Baked Potato Chips Recipe: Oven-Crispy Without the Grease

This crispy baked potato chips recipe delivers restaurant-quality crispiness without the grease or mess of deep-frying. 🔥 The secret lies in precise slicing, thorough drying, and baking at high heat—transforming simple potatoes into addictively crunchy bites that hold their shape.

I’ve perfected this method after countless batches, ensuring every chip stays crispy even after cooling.

What sets these apart is the two-step drying process that eliminates excess moisture before baking, plus a 425°F oven that creates that ideal caramelized crust. You’ll need just three ingredients—potatoes, oil, and salt—but the technique makes all the difference.

The chips turn golden and shatteringly crisp in about 20 minutes, with zero guesswork.

Once baked, these chips are versatile enough for any occasion: serve them as a snack with ketchup or sour cream, sprinkle with spices for a savory kick, or even use them as a crunchy topping for soups and salads.

The best part? They stay crispy for 3-4 days when stored in an airtight container, making them perfect for meal prep.

This isn’t just another potato chip recipe—it’s a foolproof method for crispy, healthy(ish) chips that taste like they came from a diner. Ready to make the switch from store-bought? Let’s get started.

Ingredients for baked potato chips recipe crispy

Three core ingredients plus technique create restaurant-style crispiness at home.

Russet potatoes are non-negotiable—their low moisture content and starch content make them ideal for crispy chips. Organic russets from Whole Foods or Trader Joe's work best, but any russet will do. Look for potatoes that are firm, smooth-skinned, and free of sprouts. The uniform size ensures even cooking—cut larger potatoes into smaller pieces if needed. For extra crispiness, I always use organic russets because their thicker skins hold up better during the two-step drying process. If you can't find russets, Yukon Golds are a second choice, though they'll be slightly less crisp.

Avocado oil is a must for its high smoke point—425°F won't break it down like other oils. Trader Joe's and Costco carry it affordably, or use refined olive oil in a pinch. The cornstarch is optional but adds that extra crunch—Bob's Red Mill is my go-to brand for consistent texture. For seasoning, smoked paprika adds depth without overpowering, while garlic powder enhances the savory notes. If you don't have paprika, a pinch of cayenne gives a similar smoky kick. The key is thorough drying—pat dry with paper towels after each drying step to eliminate all moisture before baking.

Store baked chips in an airtight container at room temperature for 3-4 days—they lose crispness if exposed to air. For longer storage, freeze portions in a single layer on a tray before transferring to a bag for up to 3 months. Reheat in a 350°F oven for 5-10 minutes to restore crispness. These chips reheat beautifully, making them perfect for meal prep. Avoid stacking chips in the container—they'll turn soggy faster. A light sprinkle of salt before serving keeps them fresh-tasting longer.

Step-by-step instructions for oven-crispy potato chips

Here's how to achieve restaurant-quality chips with perfect texture and zero oil mess.

Start by thoroughly washing the 2 large Russet Potatoes under cold water to remove any dirt or debris. Use a sharp chef's knife to cut them into ¼-inch thick slices—uniform thickness is key for even cooking. I like to work on a damp paper towel to prevent sticking while slicing.

Lay each slice on the 4 sheets Paper Towels and pat them completely dry with additional sheets if needed. Moisture is the enemy of crispy chips—any remaining dampness will steam the potatoes instead of crisping them. You'll notice the slices will start to stick together slightly; separate them gently with your fingers. Let them air-dry for 10 minutes while you prepare the seasoning.

In a medium bowl, combine the 1 tbsp Cornstarch, 1.5 tsp Diamond Crystal Kosher Salt, 0.5 tsp Paprika, and 0.25 tsp Garlic Powder. The cornstarch acts as a natural thickener that creates an extra crispy exterior, while the paprika and garlic powder add depth of flavor without overpowering.

Add the potato slices to the bowl and toss gently but thoroughly to coat each piece evenly. I use a silicone spatula to ensure every surface gets covered—don't skip this step. The seasoning should cling to the slices rather than just sitting in the bottom of the bowl. If you notice some slices aren't well-coated, add them back to the bowl and toss again.

Line the 1 whole Baking Sheet with parchment paper, leaving a ½-inch border around the edges. This prevents the chips from sticking and makes cleanup effortless. Arrange the seasoned potato slices in a single layer on the baking sheet, leaving about ½-inch space between each piece. Overlapping will cause uneven cooking and steaming.

Here's the thing—don't be tempted to double-layer the baking sheet. The chips need room to crisp, not steam. If you have more slices than fit comfortably, use a second baking sheet. The goal is even browning and crispiness, not crowded, soggy chips. Once arranged, lightly spray with 0.25 cup Avocado Oil using an 8-inch spray bottle—just enough to coat lightly, not soak.

Preheat your oven to 425°F with the rack positioned in the middle position. This high temperature ensures rapid cooking and maximum crispiness. Once preheated, carefully slide the baking sheet into the oven and bake for 15-18 minutes, flipping the chips halfway through at the 8-minute mark.

Watch for the edges to turn golden brown while the centers remain slightly pale. They'll crisp up further as they cool. The chips are done when they're crisp to the touch and have developed a slight char in spots. If you're unsure, remove one and let it cool for 2 minutes—it should snap when bent, not bend like fresh potato.

Remove the baking sheet from the oven and let the chips cool on a wire rack for 5-10 minutes. This cooling period is crucial—it allows the residual heat to finish cooking the centers while preventing them from becoming soggy from condensation. Don't skip this step; impatient cooling leads to limp chips.

Serve immediately while still crispy. The chips should be light and airy with a satisfying crunch that gives way slightly to a tender interior. Store any leftovers in an airtight container at room temperature for up to 3 days, but they won't be as crispy as fresh. For best results, serve as soon as they're cooled enough to handle.
