Why You'll Love This Recipe

I have tried countless fries recipes over the years, but this method nails that luscious, thin-cut, crispy texture—just like McDonald’s, but homemade. It’s become my go-to because it’s surprisingly easy, and the results always impress my friends and family.

Two-step frying technique: This ensures fries are perfectly crispy on the outside and tender inside without being greasy.
Vinegar blanch: A simple vinegar soak adds flavor and helps the fries hold their structure during frying.
Perfect cut size: Cutting the potatoes into ¼-inch sticks creates that iconic thin fry everyone loves.
Peanut oil frying: High smoke point oil keeps fries crispy and optimizes browning.

Ingredients & Why They Work

Choosing the right ingredients is key here, especially the potatoes and oil. I always reach for russet potatoes since they have the perfect starch content to get that crisp exterior and soft interior. And yes, peanut oil might not be your everyday oil, but it’s a game-changer for frying at home.

Russet potatoes: Their high starch and low moisture make them ideal for crispy, golden fries.
Distilled white vinegar: Added to boiling water to help the fries maintain structure and add a subtle tang.
Kosher salt: For seasoning both the blanching water and finishing the fries to taste.
Peanut oil: With its high smoke point, it’s perfect for deep-frying without breaking down or imparting off flavors.

Make It Your Way

The magic of this Crispy Thin French Fries Recipe lies in its simplicity, but that doesn't mean you can't make it your own! From seasoning twists to cooking oils, there's plenty of room to customize while keeping that iconic crunch and golden finish.

Herb-Infused Twist: I love tossing the fries with a sprinkle of rosemary or thyme right after the second fry. It adds a fragrant layer of flavor that brightens up the classic taste.
Spicy Kick: Mix a little smoked paprika or cayenne pepper with your kosher salt for a subtle spicy note that pairs beautifully with the crispy texture.
Oil Alternatives: While peanut oil gives a great flavor and high smoke point, I've also had success using canola oil or vegetable oil when peanut allergy is a concern or pantry options are limited.
Dip it Differently: Beyond ketchup, try serving your fries with garlic aioli, tangy mustard, or even a dash of truffle oil and parmesan for a gourmet spin.
Sweet Potato Swaps: For something seasonal, you can try the same method with sweet potatoes—just keep an eye on timing since their moisture content is different.

Next to the fries, on the right side of the plate, sits a small white square bowl filled with thick, deep red ketchup. A light dusting of salt is sprinkled on the plate near the fries. The plate rests on a white marbled surface with a soft white cloth casually placed nearby. Photo taken with an iphone --ar 2:3 --v 7

Step 1: Boil and Vinegar Bath to Lock in Crispiness

Start by peeling and cutting 2 pounds of russet potatoes into thin ¼-inch by ¼-inch fries. Submerge them in a large saucepan with 2 tablespoons of distilled white vinegar, 2 quarts of water, and 2 tablespoons of kosher salt. Bring this to a rolling boil over high heat and let it cook for 10 minutes. You'll want the fries to be fully tender but not falling apart—this step is key for the perfect texture. Drain them thoroughly and spread them out on a paper towel–lined rimmed baking sheet, letting them dry for 5 minutes to remove any excess moisture.

Step 2: First Fry – The Quick Blanch for Crunch

While the potatoes dry, heat 2 quarts of peanut oil in a large Dutch oven or wok to 400°F (204°C). Add about one-third of the fries at a time—the oil temperature should drop to around 360°F (182°C). Fry them for 50 seconds, gently moving them around with a wire mesh spider or slotted spoon. Remove the batch onto a second paper towel–lined rimmed baking sheet to drain. Repeat with the remaining fries, making sure the oil returns to 400°F each time. After all fries are cooked, allow them to cool to room temperature for about 30 minutes. For that extra-crispy, unbeatable texture, I recommend freezing the fries overnight or up to 2 months before the next step.

Step 3: Second Fry – Achieving the Signature Golden Crisp

Return the oil heat back up to 400°F. Fry half of the potatoes at a time until they turn crisp and light golden brown—about 3 ½ minutes. Keep adjusting the heat to maintain the oil temperature near 360°F to avoid burning while ensuring crispiness. Once cooked, drain the fries on paper towels and season immediately with kosher salt. To keep them warm and crispy as you finish frying the rest, place them on a wire rack set over a sheet tray in a 200°F (90°C) oven. Serve your fries hot and enjoy every crunchy bite!

Top Tip

These tips will help you master our Crispy Thin French Fries Recipe, so every batch comes out perfectly golden and crunchy—just like your favorite diner fries.

Don’t Skip the Vinegar Boil: This simple step not only seasons the potatoes but also firms them up, helping you get that iconic crunch we all crave.
Patience During Drying: After boiling, drying your fries thoroughly on paper towels is a game changer. Moisture is the enemy of crispiness, so give them that 5-minute rest.
Control Your Oil Temperature: Using a thermometer to keep your oil between 360°F and 400°F during both fries batches keeps them from greasing up or burning.
Freeze for Flavor and Crunch: If you have the time, freezing your fries overnight between the first and second fry makes a noticeable difference—it locks in texture and deepens flavor.

Garnishes

Keep things simple to let those perfectly crispy fries shine! Sprinkle a little extra kosher salt just after frying. Experiment with garlic powder, smoked paprika, or finely chopped fresh herbs like parsley or rosemary for a burst of flavor that complements the crunch beautifully.

Side Dishes

These fries pair wonderfully with classic burgers, juicy grilled chicken, or crispy fish sandwiches. Serve alongside a creamy coleslaw or a fresh garden salad for a balanced meal. And don’t forget the dipping sauces—ketchup, garlic aioli, or a tangy chipotle mayo will elevate every bite.

Make Ahead and Storage

Storing Leftovers

Store any leftover fries in an airtight container lined with paper towels to absorb excess moisture. They’ll stay fresh in the fridge for up to 2 days, but crispiness may diminish over time.

Freezing

For best results, freeze your fries after the first fry and cooling step. Arrange them in a single layer on a rimmed baking sheet lined with parchment paper, freeze overnight, then transfer to a sealed freezer bag. They can be kept frozen for up to 2 months and crisp right up during the final frying.

Reheating

To bring leftovers back to life, spread fries out on a baking sheet and heat in a 400°F (204°C) oven for 5–7 minutes. This method restores much of the crispiness without drying them out like a microwave does.

Frequently Asked Questions:

Why do we boil the fries with vinegar before frying?

Boiling the potatoes in water with vinegar helps set their structure, making them less likely to fall apart during frying. The vinegar also adds a subtle tang and helps achieve a crisp exterior.

Can I use oils other than peanut oil?

Yes! While peanut oil’s high smoke point makes it ideal, you can substitute canola or vegetable oil if preferred. Just make sure to maintain the frying temperatures carefully.

Is freezing really necessary?

Freezing after the first fry is optional but highly recommended. It helps dry out the fries further and solidifies their structure, leading to extra crispiness on the second fry.

How can I keep fries crispy if making ahead?

Keep cooked fries warm and crisp on a wire rack in a 200°F (90°C) oven if you’re frying multiple batches or serving later. For leftovers, reheating in a 400°F oven helps regain crispiness without sogginess.
