Crispy Pommes Frites Recipe: Thin-Cut French Fries

Few side dishes can compete with a pile of freshly fried pommes frites. Thin, golden, and audibly crisp on the outside with fluffy potato inside, these classic fries are exactly what you want beside a burger, steak, sandwich, or bowl of mussels—or simply served on their own with a good dipping sauce.

The secret to truly crisp homemade fries is not a complicated ingredient list. Potatoes, frying oil, and salt are really all you need. What matters is the technique. The potatoes are cut into thin, even sticks, soaked in cold water to remove excess surface starch, thoroughly dried, and then fried twice.

The first fry cooks the potatoes through without deeply browning them. After a brief rest, the second fry happens at a higher temperature, creating the crisp, golden shell that makes pommes frites so irresistible.

Serve them immediately with ketchup, mayonnaise, garlic aioli, Dijon mustard, or use them as the foundation for homemade poutine.

🍟 Crispy Pommes Frites Recipe

Prep time: 15 minutes
Soaking time: 30 minutes
Cook time: About 15 minutes
Total time: About 1 hour
Servings: 4–6

Ingredients

2 pounds russet or Idaho potatoes
2 quarts canola, vegetable, peanut, or another neutral high-heat frying oil, as needed
Fine sea salt or kosher salt, to taste
Freshly ground black pepper, optional
Chopped fresh parsley, optional

🔪 Cut the Potatoes into Thin Fries

Peel the potatoes if you prefer completely smooth pommes frites, or leave some or all of the skins in place for a more rustic appearance.

Cut each potato lengthwise into slices approximately 1/4 inch thick, then stack several slices and cut them again into 1/4-inch sticks.

Try to keep the fries relatively uniform. Very thin pieces can become overly dark before thicker ones crisp, while unusually thick fries may remain soft when the rest are ready.

A sharp chef’s knife works perfectly well. A French fry cutter or mandoline with the appropriate attachment can make the job faster if you prepare fries frequently.

💧 Soak the Potatoes in Cold Water

Place the cut potatoes in a large bowl and cover them completely with cold water.

Let them soak for at least 30 minutes. If you want to prepare them ahead, they can soak in the refrigerator for several hours.

The water may become cloudy as starch leaves the cut surfaces of the potatoes. Removing some of that surface starch helps keep the fries from sticking together and contributes to a cleaner, crisper exterior.

Once the soaking time is complete, drain the potatoes thoroughly.

🧻 Dry the Potatoes Completely

Spread the drained potato sticks across clean kitchen towels or several layers of paper towel and pat them thoroughly dry.

This is an important step for both crispness and safety. Water and hot frying oil do not mix well, and wet potatoes can cause dangerous splattering.

Take the extra minute to make sure there are no puddles of water hiding among the fries before they go anywhere near the oil.

🌡️ Heat the Oil for the First Fry

Pour the frying oil into a large, heavy-bottomed Dutch oven or deep pot. The oil should be deep enough for the fries to move relatively freely, but do not fill the pot excessively.

Heat the oil to 325°F using a deep-fry or candy thermometer.

A thermometer makes homemade fries much easier because the oil temperature changes every time cold potatoes are added.

Keep the pot handles turned away from the edge of the stove, and never leave hot frying oil unattended.

🍟 First Fry: Cook the Potatoes

Working in small batches, carefully lower some of the dried potato sticks into the 325°F oil.

Do not crowd the pot. Adding too many potatoes at once causes the oil temperature to fall sharply, which can make the fries greasy and unevenly cooked.

Fry each batch for about 3 to 4 minutes, or until the potatoes are tender and pale with little or no deep golden color.

This first fry is not meant to make them crisp and brown. Its job is to cook the interior.

Remove the potatoes with a spider or slotted spoon and transfer them to a wire rack set over a baking sheet. Repeat with the remaining potatoes.

Let the first-fried potatoes rest for about 10 to 15 minutes while you increase the temperature of the oil.

🔥 Second Fry: Make Them Golden and Crispy

Increase the oil temperature to 375°F.

Return the fries to the hot oil in small batches and fry for another 2 to 3 minutes, or until deeply golden and crisp.

Because the potatoes are already cooked inside, this second frying stage can happen relatively quickly. Watch them closely.

Lift the fries from the oil and allow the excess fat to drain briefly before transferring them to a large bowl or paper towel-lined tray.

Season immediately with salt while the fries are still piping hot.

Repeat with the remaining batches, allowing the oil to return to approximately 375°F between each one.

Serve immediately.

🥔 What Are Pommes Frites?

Pommes frites simply means fried potatoes in French, and the term is widely used for the thin fries associated with French and Belgian cooking.

They are typically thinner than many steak fries or pub-style chips and are valued for their contrast between a crisp exterior and tender center.

Pommes frites are famously served with steak in steak frites, alongside mussels in moules-frites, and with an enormous variety of sauces.

In Belgium and parts of Europe, mayonnaise is an especially familiar accompaniment. Ketchup remains an easy favorite, while garlic aioli, mustard, and herb sauces all work beautifully too.

🥔 Why Russet Potatoes Make Great Fries

Russet potatoes are an excellent choice because their relatively high starch content helps create a fluffy interior and crisp exterior.

Waxy potatoes tend to retain a denser, creamier texture after cooking. They can still be fried, but they do not produce quite the same classic French fry result.

Idaho potatoes are another excellent choice; many potatoes sold under the Idaho name are russet varieties.

Look for large, firm potatoes without soft areas, green patches, or extensive sprouting. Long potatoes also make it easier to create attractive fries of roughly equal length.

📏 How Thin Should Pommes Frites Be?

About 1/4 inch thick is an excellent target.

The current Pop & Thistle recipe already calls for thin 1/4-inch strips, and I would keep that measurement because it distinguishes these from thicker pub fries or steak fries.

Consistency matters more than achieving mathematically perfect dimensions.

A few slightly thinner fries will simply become extra crisp, but dramatically different sizes make frying harder because they finish at different times.

💦 Why Soak Potatoes Before Frying?

Cut potatoes have starch coating their exposed surfaces.

Soaking them in cold water rinses away some of that excess starch while also preventing the cut potatoes from discoloring as they wait to be cooked.

Food Network’s double-fried fry methods similarly soak cut russet potatoes before frying, with some recipes allowing a soak from 30 minutes up to overnight.

For this recipe, 30 minutes is a practical minimum that fits easily into dinner preparation.

The most important step after soaking is drying. Potatoes that leave the water bath need to be thoroughly dried before going into hot oil.

🍳 Why Fry French Fries Twice?

The double-fry technique separates two jobs that are difficult to accomplish perfectly at the same time.

During the first fry at the lower temperature, the potato cooks through and the interior softens without allowing the outside to become deeply browned.

The fries then rest briefly.

During the hotter second fry, moisture leaves the surface quickly and the outside becomes deeply golden and crisp while the already-cooked interior stays fluffy.

The additional step is worth it if your goal is crisp restaurant-style fries.

🌡️ Why Oil Temperature Matters

Maintaining the right oil temperature is one of the biggest differences between crisp fries and greasy fries.

When potatoes enter oil that is too cool, they take longer to develop a crust and can absorb more oil.

If the oil becomes excessively hot, the outside may turn dark before the desired texture develops.

A deep-fry thermometer takes most of the guesswork out of the process.

After adding each batch, expect the oil temperature to fall somewhat. Adjust the burner and allow the oil to recover before adding the next batch.

Do not compensate by overcrowding the pot. Smaller batches produce better fries.

🛢️ What Oil Is Best for Pommes Frites?

Choose a neutral oil suitable for high-temperature frying.

Canola oil and vegetable oil are widely available and work well. Peanut oil is another excellent frying oil and is used in many French fry recipes.

The oil should not contribute a strong flavor that competes with the potato.

Extra-virgin olive oil is generally not the most practical choice for deep-frying a large batch of pommes frites. Neutral oils are usually more economical and better suited to this particular cooking method.

🧂 Salt the Fries Immediately

Salt sticks best when the fries have just left the oil and still have a thin film of hot fat on their surface.

Transfer each finished batch to a bowl or tray and season right away.

Fine salt distributes particularly well across thin fries because the smaller crystals cling easily.

If you are making several batches, season each one individually rather than waiting until every fry has finished cooking.

Taste before adding another round of salt at the table. Thin fries offer a great deal of surface area, so a modest amount can go a long way.

🌿 Should You Add Herbs?

You certainly can, but I would move herbs from the main recipe to an optional variation.

The existing Pop & Thistle recipe lists rosemary or thyme almost as standard ingredients. Classic pommes frites are usually perfectly good with nothing more than salt.

Fresh parsley is an easy addition because it provides freshness without overwhelming the potato.

For rosemary fries, finely mince a small amount of fresh rosemary and toss it with the fries immediately after cooking.

Garlic and parsley are another excellent combination, especially when tossed with a small amount of melted butter.

🧄 Garlic-Parsley Pommes Frites

For garlic fries, melt about two tablespoons of butter in a small saucepan and gently cook one finely minced garlic clove just until fragrant.

Remove it from the heat and stir in chopped fresh parsley.

Drizzle only a small amount over the freshly fried potatoes and toss gently.

Do not saturate the fries with butter or they will lose their crisp texture.

Finish with salt and serve immediately.

🧀 Parmesan Fries

Freshly grated Parmesan is another easy variation.

Fry and salt the potatoes normally, then toss them with a few tablespoons of finely grated Parmesan while they are still hot.

Add chopped parsley and freshly cracked black pepper if desired.

Use finely grated rather than thickly shredded cheese so it distributes evenly and clings to the hot potatoes.

Parmesan fries are particularly good with garlic aioli.

🌶️ Spicy Pommes Frites

For a little heat, combine salt with a pinch of cayenne, smoked paprika, or chile powder.

Sprinkle the seasoning over the fries immediately after the second fry.

You can also serve them with a spicy mayonnaise or chipotle aioli instead of adding chile directly to the potatoes.

When seasoning fries with spice blends, check whether the blend already contains salt before adding additional salt.

🥣 Best Dipping Sauces for Pommes Frites

Ketchup may be the easiest option, but thin fries are made for dipping.

Mayonnaise is a classic European accompaniment and can be transformed quickly with garlic, mustard, herbs, or hot sauce.

Garlic aioli, Dijon mayonnaise, curry mayonnaise, spicy mayo, and truffle mayonnaise all work beautifully.

For something tangier, try malt vinegar or a mustard-forward dipping sauce.

And if you have homemade gravy and cheese curds available, these pommes frites make an excellent starting point for poutine.

🇨🇦 Turn Them Into Poutine

Freshly fried potatoes are the foundation of good poutine.

Pile the hot pommes frites onto a serving plate, scatter fresh cheese curds over them, and pour hot gravy over the top.

The gravy should be hot enough to soften the cheese curds slightly without completely dissolving them.

Because poutine adds plenty of salt from both the cheese and gravy, season the fries a little more cautiously if you know that is how they will be served.

🥩 What to Serve with Pommes Frites

Steak and fries may be the iconic combination, but pommes frites go with practically anything that would normally be served with French fries.

Serve them alongside burgers, grilled chicken, fried fish, hot dogs, or sandwiches.

They are excellent beside a Philly cheesesteak because the thin crisp potatoes contrast nicely with the soft bread, beef, onions, and melted cheese.

A large plate can also work as an appetizer when accompanied by several dipping sauces.

For a bistro-inspired meal, serve them with steak and a simple green salad dressed with a sharp vinaigrette.

🔥 Can You Make Pommes Frites in the Oven?

Yes, although oven fries will not have exactly the same texture as true twice-fried pommes frites.

Cut and soak the potatoes as directed, then dry them extremely well.

Toss them lightly with neutral oil and spread them across a large baking sheet without overlapping.

Bake in a hot oven, around 425°F, turning the fries partway through cooking so several sides have direct contact with the hot pan.

Continue cooking until deeply golden and crisp, then season immediately.

This method uses considerably less oil and is convenient for everyday meals, but deep-frying remains the best method when you want the classic pommes frites texture.

💨 Can You Make Them in an Air Fryer?

Yes.

Cut, soak, and thoroughly dry the potatoes, then toss them with a small amount of neutral oil.

Arrange the fries in the air fryer basket without packing them tightly together.

Cook around 380–400°F, shaking the basket several times during cooking, until the potatoes are golden and crisp.

Cooking time varies considerably among air fryers and according to the thickness of the potatoes, so check the fries frequently toward the end.

You may need to work in several batches. Overcrowding an air fryer interferes with the circulation that creates its crisp texture.

🍟 How to Keep Fries Crispy Between Batches

Fresh fries begin losing crispness as they sit, particularly if they are piled on top of one another while steaming hot.

A wire rack set over a baking sheet is ideal for draining the first-fried potatoes because air can circulate underneath them.

After the second fry, serve each batch as soon as practical.

If you absolutely need to hold finished fries briefly, place them in a single layer on a rack in a low oven. Do not cover them, because trapped steam quickly softens the crust.

For the very best experience, however, fries should move from fryer to salt to table as quickly as possible.

🧊 Can You Prepare the Potatoes Ahead of Time?

Yes.

Cut the potatoes and keep them completely submerged in cold water in the refrigerator for several hours or overnight.

Drain and dry them thoroughly before frying.

You can also complete the first frying stage ahead of time. Let the par-fried potatoes cool completely and refrigerate them, then perform the hot second fry immediately before serving.

This can be particularly useful when making fries for guests because most of the preparation can be finished before everyone sits down.

🔥 How to Reheat Leftover Fries

Freshly fried pommes frites are unquestionably best immediately after cooking, but leftovers can still be revived.

Avoid the microwave if crispness matters. Microwave reheating tends to make fried potatoes soft and flexible.

Instead, spread the fries across a baking sheet and heat them in a hot oven until crisp and thoroughly warmed.

An air fryer is another excellent option because circulating dry heat helps restore the exterior.

Reheat only as many fries as you expect to eat. Repeated cooling and reheating will continue degrading the texture.

❄️ Can You Freeze Homemade Fries?

Yes, and the double-fry method lends itself surprisingly well to freezing.

Complete the first fry, let the potatoes cool completely, and arrange them in a single layer on a baking sheet.

Freeze until firm, then transfer them to a freezer-safe bag or container.

When you want fries, perform the second frying stage from frozen, working carefully because any surface ice can cause hot oil to splatter.

This gives you homemade fries that can go from freezer to table much more quickly than starting with raw potatoes each time.

⚠️ Deep-Frying Safely at Home

Hot oil deserves your full attention.

Choose a heavy, stable pot with plenty of unused space above the oil. Never fill a pot close to the top because bubbling oil can overflow when food is added.

Make sure the potatoes are thoroughly dry before frying and lower them into the oil carefully rather than dropping them from a height.

Keep children and pets away from the cooking area and turn pot handles inward where they cannot be bumped.

Never leave hot oil unattended.

If frying oil ever catches fire, do not pour water onto it. Turn off the heat if you can do so safely and cover the pot with a metal lid.

❓ Frequently Asked Questions

What is the difference between pommes frites and French fries?

The terms largely refer to the same basic food—potatoes cut into sticks and fried. Pommes frites is the French term and is often associated with relatively thin, crisp fries served in French and Belgian cooking.

Why do you fry pommes frites twice?

The lower-temperature first fry cooks the potato interior, while the hotter second fry develops the crisp, golden exterior. Separating those two stages makes it easier to achieve fluffy centers and crunchy surfaces.

How thin should pommes frites be?

About 1/4 inch thick is an excellent size for thin-cut pommes frites. Try to keep the pieces reasonably uniform so they cook at approximately the same rate.

Do you have to soak potatoes before frying?

You can fry potatoes without soaking them, but soaking removes excess surface starch and helps keep the cut potatoes from discoloring before cooking. For this recipe, a 30-minute cold-water soak is worth the extra time.

Why are my homemade fries soggy?

Common causes include potatoes that were not dried well, oil that was too cool, overcrowding the fryer, or letting finished fries sit in a pile where steam softens them.

What temperature should you fry French fries?

For this double-fry method, use approximately 325°F for the first fry and 375°F for the second fry.

Can you reuse French fry oil?

Frying oil can sometimes be strained and reused if it has not burned or developed unpleasant odors or flavors. Let it cool completely before handling and store it appropriately. Discard oil that smells rancid, looks excessively degraded, or has been overheated.

Do pommes frites need to be peeled?

No. Peeling creates the smooth appearance associated with many classic pommes frites, but clean potato skins can be left on for a more rustic fry.

🍟 The Secret to Better Homemade Fries

Great pommes frites come down to technique rather than complicated ingredients.

Start with starchy potatoes, cut them into thin and even sticks, soak away some of the surface starch, and dry them completely. Then fry them once at a lower temperature to cook the center and again at higher heat to make the outside deeply golden and crisp.

Salt them the instant they leave the oil and serve them without delay.

Whether they end up beside a steak, underneath poutine gravy and cheese curds, next to a sandwich, or simply in a bowl with garlic aioli, properly made pommes frites rarely stay on the table for long.
