The Secret to Perfect French Fries (2024)

Before I went to culinary school, I thought the procedure for making French fries went something like this: soak potatoes in water, pat dry, throw into sizzling hot oil, drain, eat. (And if all else fails, make a run for McDonald's.) I had the basic idea, but then I started classes at the French Culinary Institute. If culinary training has taught me anything, it's that a little technique can elevate the most basic food from ordinary to extraordinary.

In addition to taste, what separates a so-so French fry from a superb one is its texture. A properly made fry must hit the oil twice--once at a lower temperature, and then again at 350 degrees Fahrenheit--to get the perfect creamy interior and crunchy exterior. Before all that, though, the secret is to briefly poach them in boiling water (or "blanch" them) before they go into the hot oil. This ensures that the fries are cooked all the way through before getting crisped up in the fryer.

  1. Cut 2 large Russet potatoes into uniform pieces so the fries cook evenly, about a 1/4 inch thick and 2 1/2 to 4 inches long. Note: Peeling is optional. If you do not peel the potatoes, scrub them well before cutting.

  2. Add potatoes to a small but deep saucepan filled with cold water and bring to a boil. Once boiling, let potatoes cook for about 5 minutes and then remove. Air dry on paper towels; about 10 minutes. (Make sure the potatoes are dry before frying; you can dab them off with the paper towel if necessary.)

  3. Once potatoes are thoroughly dry, fry them 300-320 degree vegetable oil in a deep fryer or a large pot (a Dutch oven would work). You'll need to use a deep-fry or candy thermometer to make sure the oil stays at the right temperature. Once the thermometer comes up to temp, turn the heat off. Fry potatoes in small batches, maybe 7-8 fries per batch, so that they cook evenly. At this point, the potatoes should not have any color. Remove and drain on paper towels. After the first batch is finished, turn the heat back on so that the oil to comes up to temperature.

  4. Now for the second fry. Heat oil to 350 degrees F and fry potatoes until they are a light golden brown; 2-4 minutes. Note: Fries will continue to get a little darker out of the oil. Drain and then toss in a bowl with salt. Serve on a plate or eat them straight out of that bowl!

What does baking powder do to french fries? ›

The baking soda is clutch, as it alkalizes the water/potatoes and contributes to the crunch effect. The salt goes both in the water and on the potatoes for maximum seasoning. A big glug of olive oil makes them super crunchy and that fat gives the super high heat something to work with.

What happens if you don't soak potatoes before making fries? ›

This step is commonly missed in making homemade fries, but it might be one of the most important! Soaking your fries in cold water helps remove excess starch, which allows for crispy, golden fries!

Why don't McDonald's fries taste the same? ›

Why does McDonald's soak their fries in sugar? ›

The dextrose, a natural form of sugar, is to help achieve a uniform golden color and the sodium acid pyrophosphate prevents the potatoes from turning grayish after they are cooked, according to McDonald's. Fear said these ingredients are of no health concern.

Why won't my fried potatoes get crispy? ›

This sure sounds a lot like potatoes that have been stored too long, in too cold of an environment before cooking. When potatoes are held below 41°F for too long a period, the starches convert to sugar and it changes the cooking chemistry.

How long should you soak potatoes for fries? ›

Place them in a large bowl and cover with cold water. Allow them to soak, 2 to 3 hours. (You can also stick them in the fridge and let them soak overnight.) When you're ready to make the fries, drain off the water and lay the potatoes on 2 baking sheets lined with paper towels.

What does vinegar do to french fries? ›

When a small amount of vinegar is added to the soaking water before frying, it can help impart a tangy flavor to the fries without making them taste overly vinegary. The acid in the vinegar can also help to slightly break down the surface of the potatoes, aiding in the development of a crispier texture during frying.

How long can potatoes soak in water? ›

How long can peeled and cut potatoes sit in water before cooking, before they begin taking on too much water? A: We usually recommend no more than 24 hours.

Why do soaking potatoes make them crispier? ›

Also, if you are going to fry them they will turn out crispier. Soaking them helps to remove the starch. Just make sure you dry them well before frying. The water will spatter and cause burns but also steam the potatoes and not get crunchy and crisp.
