These crispy homemade fries start with russet potatoes cut into thin sticks, simmered briefly in vinegar water, steamed dry, and fried in two batches until golden outside and fluffy inside.
The vinegar in the water helps the potato sticks hold their shape, and the short boil cooks the centers so the frying stage only has to crisp the outside. Season them with salt while they are hot and serve them straight from the pot.

Why This Crispy Homemade Fries Recipe Works
Rinsing the cut potatoes removes surface starch that makes fries gummy, and simmering them in lightly salted vinegar water cooks the centers until tender without letting the sticks fall apart.
Steaming the boiled fries dry on towel lined trays for 5 minutes removes surface moisture, which gives a crisp shell and less splattering in the hot oil.
Frying in small batches keeps the oil hot, so each batch turns golden and crisp instead of greasy. The result is a thin crackly coating around a soft, fluffy center.
Ingredients for Crispy Homemade Fries
- 2 1/4 pounds russet or other floury potatoes (3 to 4 potatoes)
- 2 tablespoons white vinegar
- 2 teaspoons kosher salt, for the boiling water
- 8 cups cold water, for boiling
- 4 1/4 cups canola or vegetable oil, for frying (about 1 liter)
- 1/2 teaspoon fine salt, for seasoning
- Garlic powder, smoked paprika, or grated Parmesan, for seasoning (optional)
Russet potatoes. Floury, high starch potatoes such as russet give a fluffy interior and a crisp exterior. Waxy potatoes tend to stay dense.
White vinegar. A little acid in the boiling water firms the outside of the potato sticks so they hold together while you move them.
Kosher salt. Salting the boiling water seasons the potatoes through to the center, so the fries need only a light sprinkle at the end.
Frying oil. Canola or vegetable oil has a neutral flavor and a high smoke point. Use enough to come about 1 inch up the pot.
Finishing seasonings. Fine salt sticks best to hot fries. Garlic powder, smoked paprika, or grated Parmesan add variety.
How to Make Crispy Homemade Fries
1. Cut the potatoes Peel the potatoes and cut them into sticks about 1/4 inch thick with a serrated knife. Keep the cut sticks in a bowl of cold water so they do not brown.
2. Rinse the sticks Move the sticks to a colander and rinse them under running water for 15 to 20 seconds.
3. Simmer in vinegar water Combine 8 cups of cold water, the vinegar, and the kosher salt in a large pot, add the potatoes, and bring to a boil over high heat. Reduce the heat to low so the surface is gently rippling and cook for 10 minutes.
4. Steam dry Lift the fries out with a slotted spoon onto two towel lined trays, spread them out, and let them steam dry for 5 minutes.
5. Heat the oil Pour about 1 inch of oil into a heavy pot at least 4 inches deep, leaving at least 3 inches between the oil and the rim. Heat the oil to 350 degrees F.
6. Fry the first batch Add half of the fries and fry for 5 to 6 minutes, turning occasionally, until deep golden and crisp. Drain on paper towels.
7. Fry the second batch Let the oil return to 350 degrees F, then fry the second batch the same way.
8. Season and serve Sprinkle the hot fries with salt right away and serve.
How to Serve Crispy Homemade Fries
Serve the fries hot in a paper lined bowl with ketchup or a creamy dip. They go well beside pulled chicken sandwiches, oven baked barbecue chicken, or a cold bowl of macaroni salad, and they make a comforting side next to pot roast on a cold evening.
How to Store and Reheat Crispy Homemade Fries
Fries are best eaten right away, but leftovers can be cooled and stored in an airtight container in the refrigerator for up to 3 days. Reheat them in a 400 degrees F oven or an air fryer for 8 to 10 minutes until hot and crisp, at least 165 degrees F. Skip the microwave, which makes them soft.
Tips and Variations for Crispy Homemade Fries
Use a serrated knife. A serrated knife grips the potato skin and slices clean, even sticks.
Cut evenly. Sticks of the same thickness cook at the same pace.
Keep the oil hot. Use a thermometer and wait for the oil to return to 350 degrees F between batches.
Dry well. Water in hot oil splatters, so make sure the boiled fries are steamed dry before frying.
Fry in small batches. Crowding drops the oil temperature and leads to limp fries.
Handle hot oil carefully. Use a heavy pot with plenty of space below the rim, lower the fries in gently, and never leave hot oil unattended.
Try other seasonings. Garlic powder, smoked paprika, or grated Parmesan are easy variations.
Store them safely. Cool leftovers promptly, and Purdue Extension leftover storage guidance explains how to keep them safe.
Frequently Asked Questions About Crispy Homemade Fries
What potatoes are best for crispy homemade fries?
Russet potatoes are best because their high starch gives a fluffy center and a crisp edge. Other floury potatoes such as Maris Piper also work.
Why do you boil the potatoes before making crispy homemade fries?
Boiling cooks the centers through, so the frying step only needs to crisp the outside and the fries stay fluffy.
Can I make crispy homemade fries ahead?
You can boil and steam dry the potatoes a few hours ahead, then fry just before serving for the best texture.
Can I use an air fryer?
You can finish boiled and steam dried sticks in an air fryer with a light coating of oil, though the texture will be less rich than deep fried fries.
How do I keep the oil safe?
Keep the temperature near 350 degrees F, leave room below the pot rim, and never add wet potatoes.
