Ingredients & Why They Work

Getting these fries right starts with picking the right kind of potato and the perfect frying oil. Here’s what you need and why:

Flat lay of peeled large russet potatoes cut into thin ¼-inch sticks arranged neatly next to a small white bowl filled with clear distilled white vinegar, a small white bowl containing coarse kosher salt crystals, and a small white bowl filled with golden peanut oil, all placed on a clean white marble surface, soft natural light, photo taken with an iPhone, professional food photography style, fresh ingredients, white ceramic bowls, no bottles, no duplicates, no utensils, no packaging --ar 2:3 --v 7 --p m7354615311229779997

Russet Potatoes: These starchy potatoes are ideal for crispy fries because they get fluffy inside and crisp up beautifully outside.
Distilled White Vinegar: Adds a subtle tang and helps the fries keep their shape during boiling.
Kosher Salt: Enhances flavor and helps draw out moisture for better crispness.
Peanut Oil: Its high smoke point makes it perfect for frying fries at high temperature without burning.

Make It Your Way

The beauty of this Crispy Thin French Fries Recipe is how versatile it is—you can easily customize the flavors and presentation to suit your mood or occasion. Whether you want to add a little extra seasoning or explore some creative twists, these fries are a perfect blank canvas for your culinary creativity.

Herb-Infused Twist: I love tossing the fries with finely chopped rosemary or thyme right after the final fry. It adds a fragrant, savory flavor that pairs beautifully with the fries’ crispiness.
Spicy Kick: A sprinkle of smoked paprika, cayenne, or chili powder right after frying gives these fries a subtle heat that’s just irresistible. Perfect if you like a little excitement with your crunch!
Garlic Parmesan: For a rich, indulgent variation, try mixing minced garlic and freshly grated Parmesan cheese with the fries once they’re hot. The warm fries melt the cheese slightly, creating a wonderful coating.
Vegan-Friendly Dips: Pair these fries with homemade sauces like tangy ketchup, vegan aioli, or even a creamy cashew dip to complement the crisp texture.

Step-by-Step: How I Make Crispy Thin French Fries Recipe

A pile of golden-brown French fries is placed slightly to the left on a round white plate with a dark blue inside. To the upper right of the fries, there is a small white square bowl filled with thick red ketchup. Some light seasoning is sprinkled near the fries on the plate. The plate rests on a white marbled surface with a white cloth partly visible on the left side. Photo taken with an iphone --ar 2:3 --v 7

Step 1: Prepare and Soak Your Potatoes

Start by peeling your russet potatoes and cutting them into uniform ¼-inch by ¼-inch sticks. Keep the raw potato sticks submerged in a bowl of cold water as you cut to prevent browning and to remove excess starch, which helps achieve those perfectly crispy fries. This simple soaking step is the foundation for crunchy, golden results every time.

Step 2: Blanch Your Potatoes Gently

Place the potatoes in a saucepan with the distilled white vinegar, then add 2 quarts (1.9L) of water and 2 tablespoons (24g) kosher salt. Bring the mixture to a boil over high heat, then boil for exactly 10 minutes until the potatoes are tender but still holding their shape. This blanching softens the fries just enough to cook through without breaking down. Drain the water and spread the fries on a paper towel–lined rimmed baking sheet to dry for 5 minutes—dryness here helps avoid oil splatter and ensures crispiness.

Step 3: Par-Fry for Ultimate Crisp

Heat your peanut oil in a large Dutch oven or wok to 400°F (204°C). Working in batches, add about one-third of your potatoes at a time. The temperature will drop to about 360°F (182°C); let the fries fry for 50 seconds, stirring occasionally with a wire mesh spider to keep them from sticking. Remove fries to a paper towel–lined sheet and repeat for remaining batches. Let the fries cool at room temperature for 30 minutes. For the crispiest fries, freeze them overnight or up to two months—when you’re ready, you’ll finish frying from frozen!

Step 4: The Final Fry and Season

Reheat the peanut oil to 400°F (204°C). Fry half your batch until the fries turn crisp and light golden brown, about 3 ½ minutes, keeping the oil temperature steady around 360°F by adjusting the heat accordingly. Drain immediately on paper towels and season generously with kosher salt while the fries are hot—this helps the seasoning stick beautifully. To keep fries hot and crispy while you finish the remaining batch, spread them on a wire rack in a 200°F (90°C) oven. Serve right away for that unbeatable crunch and flavor.

Top Tip

Getting that perfect golden crisp on your fries every time feels like magic, but it's really all about a few key steps that make the Crispy Thin French Fries Recipe a winner.

Double Frying: From my experience, frying the potatoes twice is the secret sauce—it gives you that unbeatable crisp without any sogginess.
Vinegar Soak: Adding vinegar while boiling keeps the fries from falling apart and helps develop that classic McDonald's-style texture I learned to love after many trials.
Temperature Control: Keeping your oil at 400°F (204°C) for frying and letting it drop during batches makes a huge difference in how evenly the fries cook.
Drying the Potatoes: Never skip drying your boiled fries on paper towels before frying—moisture is the enemy of crispiness!

How to Serve Crispy Thin French Fries Recipe

A clear glass bowl sits on a white marbled surface, filled with pale yellow potato sticks submerged in clear water. The potato sticks are long and evenly sized, stacked loosely in two layers within the bowl. The water is slightly cloudy around the edges of the potato sticks, showing they have been soaked.

Garnishes

For toppings, I love a classic sprinkle of kosher salt right after frying to help it stick perfectly. Feel free to mix it up with some garlic powder, smoked paprika, or even a dusting of Parmesan cheese for an extra pop of flavor. Freshly chopped parsley or a pinch of cayenne pepper can also add a gourmet touch!

Side Dishes

These fries pair beautifully with juicy burgers, crispy fried chicken, or even a hearty sandwich. They also make a fantastic side to a fresh, tangy coleslaw or a creamy dip like garlic aioli, ketchup, or even a zesty sriracha mayo. Basically, anything that loves to be dunked!

Make Ahead and Storage

Storing Leftovers

If you have leftovers, store them in an airtight container lined with paper towels to absorb moisture. Keep them refrigerated and enjoy within 2 days for the best texture.

Freezing

You can freeze your par-fried potatoes for up to 2 months. Simply spread them out on a baking sheet to freeze individually before transferring to a freezer-safe bag. When you're ready to enjoy, fry them from frozen for that crispy finish.

Reheating

To reheat and keep those fries crispy, pop them in a 400°F (204°C) oven for about 5 to 10 minutes or briefly refry in hot oil at 360°F (182°C) for 1-2 minutes. Avoid microwaving as it makes fries rubbery.

Frequently Asked Questions:

Why do you soak the potatoes with vinegar before frying?

The vinegar helps strengthen the potatoes' structure during boiling, preventing them from breaking apart and contributing to that perfect French fry texture reminiscent of McDonald's fries.

Can I use oils other than peanut oil?

While peanut oil is preferred for its high smoke point and neutral flavor, other oils like canola or vegetable oil can work too, but be mindful of their smoke points to avoid burning the fries.

Why is double frying necessary?

Double frying cooks the fries in two stages: the first fry cooks them through at a lower temperature, the second fry crisps them quickly at a higher temperature, resulting in fries that are tender inside and crispy outside.

Can I skip freezing before the final fry?

Freezing is optional but recommended. It helps dry the fries further and improves crispness. If pressed for time, you can skip freezing but let them cool completely before the final fry.

Making the Crispy Thin French Fries Recipe at home isn’t just about food—it’s about creating a little moment of joy, one perfectly golden fry at a time.
