Homemade Crispy French Fries Recipe (Double-Fried)

Restaurant fries are crisp on the outside, fluffy on the inside, and stay that way long enough to finish the basket. Homemade fries are usually limp, or brown on the outside and raw in the middle. The difference is not the potato or the oil. It is that restaurants fry their potatoes twice.

The first fry, at a lower temperature, cooks the potato through and drives out moisture. The second fry, at a higher temperature, crisps the outside in a couple of minutes. It sounds like more work, but the first fry can be done hours ahead, which makes fries easier to serve with dinner, not harder.

This recipe walks through the full method with a thermometer, and gives honest oven and air-fryer versions for nights when you do not want a pot of oil on the stove.

Why this recipe works

• Russet potatoes are high in starch and low in moisture, so they fry up fluffy inside and crisp outside.
• Soaking in cold water washes surface starch off the cut potatoes so they do not stick together or brown unevenly.
• The low first fry gelatinizes the interior and dries the surface; the hot second fry turns that dry surface into a crisp shell.
• Cooling between fries lets steam escape, which is what makes the final crust shatter instead of bend.

The best potatoes and oil for fries

Russets (Idaho potatoes) are the only choice for classic fries. Yukon Golds make a creamier, slightly less crisp fry that some people prefer; waxy red potatoes do not work. Leave the skin on for rustic fries or peel for classic ones.

Use a neutral oil with a high smoke point: peanut oil is the traditional favorite, and canola, vegetable or refined sunflower oil all work well. You need about 2 quarts for a Dutch oven, and the oil can be strained and reused two or three times for frying.

How to cut fries evenly

Square off the sides of each potato, cut it into 1/4- to 3/8-inch planks, then cut the planks into sticks the same width. Uniform size is what makes them all finish at the same time. A mandoline with a julienne blade or a French fry cutter makes this take a minute. For thick steak fries, cut 1/2-inch sticks and add 2 minutes to the first fry.

Oven fries and air fryer fries

Oven: after soaking and drying, toss the potatoes with 3 tablespoons of oil and 1 teaspoon of salt, spread in a single layer on two sheet pans, and bake at 450°F for 20 minutes. Flip and bake 10 to 15 minutes more until browned and crisp. They will not be quite as crisp as fried, but they are very good.

Air fryer: toss the soaked, dried potatoes with 1 tablespoon of oil and cook at 380°F in a single layer, shaking every 5 minutes, for 15 to 18 minutes. Work in two batches; crowding makes them steam.

Safety with hot oil

• Use a deep, heavy pot filled no more than halfway. The oil bubbles up when potatoes go in.
• Dry the potatoes completely; water makes hot oil spatter violently.
• Keep a lid nearby. If oil ever catches fire, cover the pot and turn off the heat. Never use water.
• Let the oil cool completely before straining and storing it.

How to store crispy french fries

• Fries are best within minutes of the second fry.
• After the first fry, they hold at room temperature for 4 hours or in the refrigerator overnight; finish with the second fry when ready.
• Leftover finished fries reheat well in an air fryer or a 425°F oven for 5 minutes. The microwave makes them soft.

Variations to try

• Garlic Parmesan fries: toss the hot fries with 2 tablespoons melted butter, 1 minced garlic clove, 1/4 cup grated Parmesan and chopped parsley.
• Cajun fries: add 1 teaspoon paprika, 1/2 teaspoon garlic powder and 1/4 teaspoon cayenne to the salt.
• Sweet potato fries: same method, but cut thicker and fry at 350°F for the second fry, since they brown faster.
• Loaded fries: top with shredded cheddar, chili from this site, sour cream and green onions.

Frequently asked questions

Why are my homemade fries soggy?

They were fried only once, the oil was not hot enough, or the pot was overcrowded. Fry twice with a cooling break, use a thermometer, and cook in batches small enough that the oil temperature does not crash when the potatoes go in.

Do I really need to soak the potatoes?

Yes. Soaking removes surface starch that would otherwise make the fries stick together and brown in patches before they crisp. Thirty minutes is enough; overnight is better.

What oil is best for French fries?

Peanut oil for flavor and a high smoke point, or canola or vegetable oil for a neutral, inexpensive option. Avoid olive oil and butter, which burn at frying temperatures.

Can I make the fries ahead for a party?

Do the first fry up to 4 hours ahead and leave the fries on a sheet pan. When guests arrive, the second fry takes only a few minutes per batch.

Can I reuse the frying oil?

Yes, two or three times for potatoes. Cool it completely, strain through a coffee filter or fine sieve, and store in a sealed container away from light. Discard it when it smells off, foams or darkens.
