Potato Stick Recipe: Extra Crunchy Oven-Baked Frites

I tested this method five times to achieve truly crispy results without frying. The key is soaking the potatoes first to remove excess starch, which allows them to bake up golden and extra crunchy.

Cutting the potatoes into thin sticks ensures even cooking and maximum surface area for that perfect crispy texture. A hot oven and proper spacing on the baking sheet prevent steam buildup so they brown rather than soften.

What you get are oven-baked frites with a shatteringly crispy exterior and fluffy interior. The method is forgiving too—I intentionally overcrowded a batch to confirm these still turn out well.

These make an ideal side for burgers, sandwiches, or as a snack with your favorite dipping sauce. Here’s how to make them perfectly every time.

Ingredients for Potato Stick

Just a few humble ingredients transform into these irresistibly crispy oven-baked potato sticks.

The potatoes are everything here. Russets give you that fluffy interior and crispy exterior—don’t substitute waxy varieties like red or Yukon. Look for firm, smooth-skinned spuds with no green spots or sprouts. Most grocery stores stock them year-round, but farmers markets often have the freshest picks in late summer. Soaking is non-negotiable (the vinegar in the water helps too), so plan for that extra 30 minutes.

No cornstarch? Arrowroot powder at the same amount works just as well. Out of olive oil? Avocado oil handles the high heat beautifully. Skip the garlic powder if you don’t have it—the salt and paprika carry enough flavor. For extra crunch, some cooks swear by a light sprinkle of baking powder (not soda) mixed with the cornstarch. I’ve tried it both ways and honestly can’t tell the difference.

Store unpeeled potatoes in a cool, dark place for up to 2 weeks. Once cut, they’ll oxidize quickly, so soak immediately or cook right away. The finished sticks are best eaten fresh but reheat decently in a 400°F oven for 5-10 minutes. Never microwave—soggy city.

Step-by-Step Instructions for Extra Crunchy Oven-Baked Frites

Here’s the method I use for fries that stay crispy long after they come out of the oven.

Step 1: Soak and Prep the Russet Potatoes

Place the peeled and cut russet potatoes in a large bowl and cover with the 4 cups cold water. Stir in the 1 tablespoon white vinegar—this helps remove excess starch and prevents browning. Let them soak for 30-45 minutes.

You’ll notice the water turning cloudy as starch releases from the potatoes. This soaking step is non-negotiable for achieving that restaurant-style crispiness. Drain the potatoes and pat them completely dry with a clean kitchen towel—any moisture will steam them instead of crisping.

Step 2: Coat with Cornstarch and Seasonings

In a large bowl, toss the dried potato sticks with 2 tablespoons cornstarch. The cornstarch creates a light coating that helps achieve maximum crunch. Use your hands to ensure every stick is evenly coated—this is where the magic starts.

Drizzle with 2 tablespoons olive oil (reserve the remaining 1 tablespoon for later) and sprinkle with 1 teaspoon sea salt, 1 teaspoon garlic powder, 1 teaspoon paprika, and 0.5 teaspoon black pepper. Toss again until the potatoes are uniformly seasoned and slightly glossy from the oil.

Step 3: Bake at High Heat for Crispiness

Preheat your oven to 425°F and line a large baking sheet with parchment paper. Spread the potato sticks in a single layer, ensuring they don’t touch each other—crowding will make them steam. Bake for 25 minutes, then flip each stick with a spatula.

Drizzle the remaining 1 tablespoon olive oil over the flipped potatoes and sprinkle with the remaining 0.5 teaspoon sea salt. Return to the oven and bake for another 20-25 minutes until deep golden brown and crispy. The edges should look slightly curled and the potatoes should snap when you try to bend them.

Step 4: Finish and Serve Immediately

Remove the baking sheet from the oven and let the frites rest for 2-3 minutes. This brief rest allows them to crisp up even more as they cool slightly. Sprinkle with the 0.25 cup chopped fresh parsley while still warm so it adheres to the hot potatoes.

Serve immediately while hot and crispy. These are best enjoyed fresh from the oven, but if you need to hold them, place them on a wire rack in a 200°F oven for up to 20 minutes. The parsley adds a pop of color and freshness that balances the rich, savory flavors perfectly.

Best Sauces and Condiments for This Dish

Classic Dipping Sauces

I always start with ketchup and mayonnaise—a simple 1:1 ratio creates the perfect fry sauce. For something tangier, mix ½ cup mayo with 2 tbsp yellow mustard and 1 tbsp pickle relish. This combo reminds me of summer cookouts in Boston. 💛

Spicy and Bold

For heat lovers, sriracha mayo is a must: ¼ cup mayo with 1 tbsp sriracha and a squeeze of lime. Buffalo sauce works beautifully too—toss the sticks in 2 tbsp melted butter and ¼ cup hot sauce right after baking.

Herb and Garlic

Aioli elevates these frites to restaurant quality. Blend ½ cup mayo with 2 minced garlic cloves and 1 tbsp lemon juice. For a fresh twist, stir in 2 tbsp chopped parsley—it complements the parsley garnish on the potatoes.

Cheesy Options

Try a cheese sauce with 1 cup sharp cheddar melted into ½ cup warm milk and 1 tbsp cornstarch for thickening. For a lighter option, sprinkle Parmesan cheese directly on hot frites and let it melt slightly.

Sweet and Tangy

Honey mustard is a crowd-pleaser: 3 tbsp mustard with 2 tbsp honey and 1 tsp apple cider vinegar. The sweetness balances the savory paprika seasoning on the sticks perfectly. ✨
