Make Ahead Friendly: Par-fried fries can be frozen to enjoy fresh, crispy fries anytime.

Ingredients & Why They Work

Before we dig in, a quick note: using the right kind of potato and oil makes all the difference. I always opt for russets because of their high starch content, which means crispier fries that aren’t oily.

Russet Potatoes: Their starchy texture is perfect for achieving that light, crispy fry.
Distilled White Vinegar: A little vinegar in the blanching water helps maintain crispiness and keeps the fries from getting mushy.
Kosher Salt: Ideal for seasoning because it sticks well and adds just the right flavor punch.
Peanut Oil: This oil’s high smoke point lets you fry at the perfect temperature without burning the fries.

Make It Your Way

One of the best parts about this Crispy Thin French Fries Recipe is how easy it is to customize it to your taste. Whether you like them spicy, herby, or just simply salted, there’s room to make these fries truly your own.

Spicy Kick: Toss your fries in a mix of smoked paprika, cayenne, and garlic powder right after frying for a smoky, spicy twist. I love this combo when serving fries as a flavorful snack!
Herb Lover’s Delight: Sprinkle freshly chopped rosemary or thyme along with kosher salt while the fries are still hot. The herb aroma adds a fresh, earthy note that’s irresistible.
Cheesy Indulgence: While still warm, sprinkle grated Parmesan cheese over the fries. It melts slightly and creates a savory, cheesy crust that takes them over the top.
Vegan & Healthy Swap: Instead of frying, par-fried fries can be baked at a high temperature for a crispier, oil-light version. Just bake them at 425°F (220°C) for about 20 minutes, flipping halfway through.
Seasonal Flavors: Experiment with truffle salt or a dusting of cinnamon and brown sugar for a sweet-savory fall treat. Perfect when paired with a cozy dipping sauce.

Step 1: Blanch with Care for Tender Fries

Start by submerging your peeled and evenly cut ¼-inch fries into a saucepan filled with 2 quarts of water, 2 tablespoons of distilled white vinegar, and 2 tablespoons of kosher salt. Bring this mixture to a boil over high heat and let it bubble away for exactly 10 minutes. The fries should become fully tender but still hold their shape—not mushy! This blanching step is your ticket to that perfect tender-but-firm bite.

Step 2: Drying Down for Maximum Crispiness

Drain the blanched fries thoroughly and spread them out on a rimmed baking sheet lined with paper towels. Let them rest for about 5 minutes so they can release excess moisture. This drying step is crucial — moisture on the surface can cause oil splatter and soggy fries, so don’t rush it!

Step 3: Par-Fry to Build a Crispy Shell

Heat 2 quarts of peanut oil in a large Dutch oven or wok over high heat until it reaches 400°F (204°C). Working in three batches, carefully add one-third of your fries to the hot oil. The temperature will dip to about 360°F (182°C) — that's perfect. Fry each batch for 50 seconds, stirring gently to keep fries from sticking. Remove fries to a paper towel–lined tray to drain.

Allow the oil to heat back to 400°F before starting the next batch. Once all fries have been par-fried, let them cool to room temperature for about 30 minutes. If you can wait longer, freezing them overnight will give you the crispiest fry imaginable when you finish frying!

Step 4: The Final Fry for Golden Perfection

Heat the peanut oil again to 400°F (204°C). Fry half of your fries until they turn crisp and a beautiful light golden brown — roughly 3 and a half minutes. Adjust the heat as needed to keep the oil temperature hovering around 360°F (182°C).

Drain the fries on paper towels, then season immediately with kosher salt while still hot so the salt sticks perfectly. Keep cooked fries warm and crispy by placing them on a wire rack set over a baking sheet in an oven heated to 200°F (90°C) while you finish frying the rest.

Step 5: Serve and Enjoy Immediately

The true magic happens when you serve these fries right away—hot, crispy, and perfectly seasoned. Pair them with your favorite sauces or enjoy them all on their own. I promise, your homemade fries will rival any fast-food classic!

Top Tip

Mastering the art of crispy fries at home is easier than you think, especially with a few insider tricks that help capture that perfect McDonald’s-style crunch and tenderness.

Vinegar Blanching: I found that blanching the potatoes in vinegar-infused water not only keeps them from falling apart but also helps boost crispiness without altering the flavor.
Don't Skip Drying: Removing excess moisture after blanching is a game changer. Wet fries lead to sogginess and annoying oil splatters—drying them on paper towels for 5 minutes really made a difference.
Two-Step Frying: Par-frying at 400°F then chilling the fries before the final fry locks in that golden crisp exterior while keeping the inside soft and fluffy.
Season Immediately: Seasoning fries with kosher salt right after frying, while they’re hot, ensures the salt sticks beautifully, giving you that perfect savory finish.

Garnishes

For an elevated experience, sprinkle your fries with freshly chopped parsley or a pinch of smoked paprika. If you're feeling indulgent, toss them with grated Parmesan cheese, or add a drizzle of garlic aioli for dipping to complement the crispy texture beautifully.

Side Dishes

These fries pair wonderfully with classic sides like juicy cheeseburgers, crispy fried chicken, or even a fresh garden salad. They’re also perfect alongside grilled sandwiches or as a crunchy addition to a hearty steak dinner.

Make Ahead and Storage

Storing Leftovers

If you have leftovers, store them in an airtight container in the refrigerator for up to 2 days. To avoid soggy fries, line the container with paper towels to absorb excess moisture.

Freezing

For the crispiest results, freeze your par-fried fries overnight or up to 2 months before the final fry. Lay them out on a baking sheet in a single layer, freeze until firm, then transfer to a freezer-safe bag. This method locks in texture and flavor.

Reheating

Reheat your fries in a preheated oven at 400°F (204°C) on a wire rack for about 5-7 minutes to crisp them back up. Avoid microwaving, which tends to make fries soggy and greasy.

Frequently Asked Questions:

Can I use a different type of potato for this Crispy Thin French Fries Recipe?

Russet potatoes are the best choice because of their high starch content and low moisture, which help create that perfect crispy exterior and fluffy interior. Using waxy potatoes like red or new potatoes may result in fries that aren’t as crisp.

Why do I need to blanch the fries in vinegar water?

Blanching in vinegar-infused water helps break down the potato’s surface starches and keeps the fries from falling apart during frying. It also contributes to a firmer texture and crispness in the final fries.

Is peanut oil necessary, or can I use another oil?

Peanut oil is recommended because of its high smoke point and neutral flavor, which are ideal for deep-frying without burning or altering the taste. However, you can use other oils with high smoke points like canola or vegetable oil if needed.

How do I keep the fries crispy if I’m making a large batch?

After the final fry, keep cooked fries warm and crispy by placing them on a wire rack set inside a baking sheet in a 200°F (90°C) oven. This prevents sogginess as you finish frying the remaining batches.

Final Thoughts

Making restaurant-quality crispy thin French fries at home is such a rewarding experience—and with this recipe, it’s totally achievable. The combination of vinegar blanching, drying, and two-step frying really makes all the difference. I hope you enjoy creating these golden, crispy fries that bring a little bit of classic American comfort right to your kitchen. Happy frying!
