Roasted Potato Chips Recipe: Vinegar-Infused Crunch Without a Fryer

Skip the fryer and master this easy roasted potato chips recipe—crispy, tangy, and packed with oven-baked perfection. The secret lies in thin, evenly sliced potatoes roasted at high heat until golden and shatteringly crisp—no oil splatter or greasy cleanup required.

I developed this method after years of experimenting with starchy vegetables, and it delivers chips that hold their shape while packing a tangy, savory punch.

This recipe transforms simple russet potatoes into addictive chips using just a few key techniques: precise slicing, vinegar soaking, and careful layering on the baking sheet. The vinegar infusion enhances natural potato sweetness while preventing sogginess, and baking at 425°F ensures maximum crispiness without burning.

You’ll need only basic equipment—a sharp knife, baking sheets, and parchment paper—but the results are undeniably professional.

What you’ll end up with are perfectly crisp potato chips with a delicate vinegar tang and clean, golden edges that crumble at the slightest touch. The process is simpler than store-bought versions yet far more satisfying, with no artificial additives or preservatives.

Each batch yields about 4 cups of chips, enough to satisfy a snack craving or impress guests with minimal effort.

For extra flavor, try sprinkling with sea salt, smoked paprika, or garlic powder before baking. These chips reheat beautifully too, making them ideal for meal prep or last-minute snacking. Let’s get started on creating your own crispy, vinegar-kissed masterpiece.

Ingredients for roasted potato chips

Four simple ingredients transform russets into addictive, vinegar-kissed chips with zero fryer mess.

Russets are non-negotiable here—their high starch content delivers that perfect crunch. Buy organic if you can, but regular russets work fine. The key is uniform slices: aim for about 1/16-inch thickness. I use a mandoline for consistency, but a sharp knife works too (just be careful). Soak the slices in cold water for 30 minutes after slicing—this removes excess starch that causes sogginess. Trader Joe's and Whole Foods usually carry russets with fewer blemishes, which means fewer spots to rot during slicing.

No white vinegar? Apple cider vinegar or lemon juice works in a pinch, though white delivers that classic tang. The olive oil is purely for crispiness—use a light variety like California extra-virgin to avoid overpowering the potato flavor. For the spices, smoked paprika from Penzeys adds depth, but any good brand will do. Want extra crunch? Toss the dried chips with cornstarch before baking—just a light dusting. And if you're short on time, skip the soak: pat the slices dry with paper towels and bake immediately, though they might be slightly less crisp.

These chips are best eaten fresh but reheat beautifully in a 200°F oven for 5-10 minutes. Store in an airtight container for up to 3 days, though they lose crispiness faster than store-bought. For longer storage, freeze the cooled chips in a single layer on a tray, then transfer to a bag. They’ll keep for up to 3 months this way. Pro tip: Portion into snack-sized bags before freezing—no more digging through a giant container for just a handful.

Step-by-step instructions for vinegar-infused roasted potato chips

Here's how to make restaurant-style chips with crispy edges and fluffy centers using just your oven.

Start by peeling the 2 lb russet potatoes and slicing them into uniform ⅛-inch thick rounds using a mandoline or sharp knife. Consistency is key—thicker slices will be soft inside, while thinner slices burn faster. Immediately submerge the slices in a large bowl of cold water to prevent browning while you work.

Drain the water and pat the potato slices completely dry using the package of paper towels. Any moisture left on the potatoes will steam instead of crisp in the oven. I press each slice between two fresh paper towels to ensure they're bone dry before proceeding. This step is non-negotiable for achieving that perfect crunch.

In a large bowl, whisk together the 0.5 cup white vinegar and 0.25 cup extra-virgin olive oil. The vinegar acts as a natural preservative and enhances the crispiness by breaking down the potato starches. Add the 1 tbsp diamond crystal kosher salt, 1 tsp smoked paprika, and 0.5 tsp garlic powder to the mixture, stirring until fully combined.

This seasoned oil will infuse the potatoes with flavor as they crisp. The vinegar also helps create that classic "chippy" tang that sets these apart from regular oven-baked potato slices. Give the mixture a final stir before adding the potatoes to ensure even coating.

Working in batches, remove the potato slices from the paper towels and toss them in the seasoned oil mixture until every surface is evenly coated. I use my hands for this step—it's more thorough than a spoon. Transfer the coated slices to the prepared baking sheets lined with parchment paper, arranging them in a single layer with no overlapping.

Leave about ½ inch between each slice. This spacing ensures even crisping and prevents soggy spots where slices touch. For extra crispiness, I like to press down gently on each slice with my fingers before baking—this creates more surface area for browning.

Preheat your oven to 425°F with the baking racks positioned in the middle and upper third positions. This two-level baking creates a convection effect that circulates hot air around the potatoes. Once preheated, bake the potatoes for 18-22 minutes, flipping them halfway through using a thin spatula.

You'll know they're done when the edges are deep golden brown and the centers are still slightly soft when pressed gently. The exact time depends on your oven—if they brown too quickly, reduce the temperature to 400°F for the second half of baking. Don't overcrowd the oven, or the temperature will drop and your chips will steam instead of crisp.

Remove the chips from the oven and let them cool on the baking sheets for 3-5 minutes. This resting period allows the starches to set and makes them extra crispy. Serve them warm for the best texture—they'll continue crisping as they cool, but the flavor is most vibrant when fresh from the oven.

For maximum crunch, store any leftovers in an airtight container for no more than 2 days. The vinegar helps preserve them longer than regular oven chips, but they're best enjoyed immediately. These chips pair perfectly with dips, soups, or even as a snack on their own—just be prepared for them to disappear quickly!
