The Secret to Perfect French Fries (2024)

Copyright iStockphoto.com/PIKSEL

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!

FAQs

Why do you soak french fries in water before frying? ›

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! The cold water bath also helps the french fries retain their shape and contributes to a fluffy inside.

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

The main reasons to cut the potatoes and pre-soak in water are: To allow the excess starches and sugars to be removed from the outer surface of the fry strips AND to keep the potatoes from browning prematurely from exposure to air. Covering in water helps the potato from turning a dark color.

Why add vinegar in water for 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.

Why do french fries taste better at restaurants? ›

Blanching: The Reason Why French Fries Taste Better

Your potatoes need to take two separate dips in hot oil to reach restaurant quality. Oil-blanching is a two-part process that reduces the moisture and starch content in your fries, helping them crisp up.

How to enhance french fries? ›

An acid will help bring out the flavor of your fries.

Try pairing frozen fries with acidic ingredients to enhance their natural potato flavor. "Fries benefit from the addition of acid," Harvey told Insider. "Toppings like citrus juice, vinegar, hot sauce, and pickles contrast the richness of the crispy fries."

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.

How hot should the oil be for french fries? ›

Heat 3 to 4 inches oil in a heavy-bottomed pot over medium heat. Use a thermometer to ensure the temperature is correct: 325 degrees for French fries, 375 degrees for shoestring and basket-weave fries.

Which potato is best for French fries? ›

And the clear winners are Idaho or russet potatoes.

These potatoes are dense and have less moisture, which is key to avoiding soggy fries. You can also use Yukon gold potatoes, which are an all-purpose potato that can be used for frying. You should avoid waxy potatoes like red-skinned, new, or fingerling potatoes.

How long can potatoes soak in water before frying? ›

Just a quick 15-30 minute soak in water does the trick if you're in a rush, though if you are planning ahead you can let the sliced russets or yes, even sweet potatoes, bathe for hours or even overnight before draining, drying, and frying them up.

What happens if you don't soak potatoes before air frying? ›

I wouldn't bother doing potatoes from the raw state, without soaking. It will take about a half an hour and the texture won't be nearly as rewarding. They just don't get very crispy without that cold soak.

What to do after soaking french fries? ›

Remove potatoes from water and dry thoroughly on paper towels. Heat oil in a deep-fryer to 375 degrees F (190 degrees C). Cook potatoes in hot oil until golden, 5 to 6 minutes. Drain on paper towels and season with salt.

What happens if you don't remove starch from potatoes? ›

Starch rich potatoes usually turn soft and crumbly, while frying or baking. So, if you are making delicacies wherein you want the potatoes to be crispy and crunchy, then removing starch is the best way to keep your wafers, fries, crispy potatoes, hash browns crisp and delicious.
