This baked potato chips salt and vinegar recipe delivers the perfect balance of bold tangy kick and shatteringly crisp texture without a speck of grease. The secret lies in thin, even slices and a precise baking technique that transforms humble potatoes into addictive, restaurant-quality chips.
I've perfected this method after countless batches—no soggy edges or uneven cooking here.
What sets these chips apart is the tart, zesty vinegar seasoning that cuts through the richness of the potato, creating that signature salt and vinegar flavor you crave. The process is simpler than you'd think: slice, season, bake, and repeat.
With just five ingredients and 30 minutes of active time, you'll have a batch of chips so crisp they'll disappear faster than store-bought.
The result is a golden, ultra-crispy snack with a tangy, slightly sweet bite that keeps you reaching for more. These chips stay fresh for days in an airtight container, making them perfect for parties, movie nights, or satisfying that mid-afternoon craving.
The thin slices ensure maximum crispiness, while the vinegar seasoning adds that signature tang that makes these chips unforgettable.
For extra crunch, try slicing the potatoes thinner or using a mandoline slicer. Experiment with different vinegars—apple cider or white wine vinegar work beautifully—for subtle flavor variations. This recipe is your ticket to homemade chips that taste better than anything you'll find in a bag.
Ingredients for baked potato chips salt and vinegar
Five ingredients, zero grease, maximum crispy tang—this is how you make chips better than the store.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 2 lb | Thinly sliced, peeled preferred |
| White Vinegar 🍶 | ¼ cup | Distilled or apple cider vinegar |
| Diamond Crystal Kosher Salt 🧂 | 2 tbsp | Fine grain preferred |
| Cornstarch 🌾 | 2 tbsp | For extra crispiness |
| Avocado Oil 🫒 | 1 tbsp | High smoke point for baking |
Russets are non-negotiable here—their low moisture content and starchy texture make all the difference. Trader Joe’s sells pre-peeled russets in bags, which saves time, but I always peel mine myself for even slices. Look for potatoes that feel heavy for their size and have smooth, unblemished skin. If you're slicing by hand, aim for 1/16-inch thickness—any thicker and they won't crisp properly. A mandoline makes this easy, but a sharp knife works too if you take your time.
White vinegar is the MVP, but apple cider vinegar adds a subtle sweetness that works beautifully. No vinegar? Lemon juice at half the amount gives a similar tang, though it lacks that classic salt-and-vinegar depth. The cornstarch is key—it creates that signature crunch, so don't skip it. As for oil, avocado oil has the highest smoke point, but any neutral oil like canola or vegetable will work. Just avoid olive oil—it burns too easily and can make the chips taste bitter.
Sliced potatoes lose moisture fast, so keep them in cold water until ready to bake. The chips stay crispy for 3-4 days in an airtight container, though they'll lose some crunch after the first day. For longer storage, freeze them in a single layer first, then transfer to a bag—they'll stay crunchy for up to a month. Pro tip: sprinkle a tiny bit of cornstarch on the container to keep them extra crispy.

Step-by-step instructions for crispy salt and vinegar potato chips
Here's how to transform simple russets into addictively crispy chips with that perfect tangy kick.
Prep the Potatoes for Perfect Slices
Start by peeling the 2 lb russet potatoes—this ensures even cooking and prevents skin from tearing during slicing. I like to cut them lengthwise into quarters first, then slice each quarter into ⅛-inch thick rounds using a mandoline or sharp knife. For consistent thickness, stack slices and cut in batches.
As you slice, soak the potato rounds immediately in a bowl of cold water. This prevents browning and removes excess starch that would make them gummy instead of crispy. Let them soak for 30 minutes while you prepare the seasoning mixture. Drain and pat completely dry with paper towels before proceeding—any moisture will steam the chips instead of crisping them.
Create the Seasoning Blend
In a small bowl, whisk together the 0.25 cup white vinegar, 2 tbsp diamond crystal kosher salt, and 2 tbsp cornstarch until fully dissolved. The cornstarch acts as a crisping agent while the vinegar delivers that signature tang. I use fine-grain salt here—it dissolves better and coats the chips more evenly than coarse varieties.
This seasoning blend is your flavor foundation. The vinegar should be completely incorporated with no grainy texture remaining. If you prefer a stronger vinegar taste, add an extra tablespoon, but start with the recipe amount—you can always adjust after tasting a test chip.
Toss and Rest for Maximum Crispiness
Transfer the dried potato slices to a large bowl and pour the seasoning mixture over them. Using clean hands or a silicone spatula, toss the potatoes gently but thoroughly until they're evenly coated. You'll notice they'll look slightly translucent—this is normal and indicates proper seasoning absorption.
Let the seasoned potatoes rest for 10 minutes at room temperature. This resting period allows the cornstarch to adhere better to the potato surfaces, creating that perfect crispy exterior. Don't skip this step—it's what transforms good chips into exceptional ones. While waiting, preheat your oven to 400°F with racks positioned in the upper and lower thirds for even baking.
Bake in Batches for Even Crispiness
Line two baking sheets with parchment paper and lightly brush each with 1 tbsp avocado oil, using a paper towel to spread it evenly. Arrange the potato slices in a single layer, leaving ½-inch between each for proper air circulation. I work in batches to avoid overcrowding—this ensures they crisp rather than steam.
Bake for 20-25 minutes, flipping the chips halfway through, until they're golden brown and crispy with no soft spots. The edges should be slightly darker than the centers—this indicates proper doneness. Watch closely in the last 5 minutes to prevent burning. Remove from oven and let cool for 5 minutes before serving—they'll crisp up even more as they cool.
Serve Immediately for Maximum Crunch
Transfer the chips to a serving bowl and toss gently with a fork to redistribute any seasoning that may have settled. Serve immediately while still crispy—these chips lose their crunch within minutes. For extra tang, offer additional white vinegar on the side. The perfect chip should be crisp enough to stand up on edge, with a satisfying crunch that gives way to the bold vinegar-salt flavor in every bite.
If you find some chips aren't perfectly crisp, simply return them to the oven for 2-3 minutes until they reach your desired texture. The secret to great homemade chips is patience—rushing leads to soggy results, but taking your time guarantees restaurant-quality crunch every time.
Pro Tips For Making Baked Potato Chips Salt And Vinegar
- USE THIN, DRY SLICES: Russets are starchy but still need care—slice them ⅛-inch thick with a mandoline (or sharp knife) and pat every slice dry with paper towels. Moisture is the enemy of crisp; I learned this after a soggy batch where I skipped this step and wondered why my chips tasted like boiled potatoes.
- SALT BEFORE BAKE: Toss the cornstarch-dusted slices in Diamond Crystal kosher salt before hitting the oven—not after. The salt needs time to adhere, and baking it in creates a crunchier, stickier crust. (Yes, even if you’re impatient like me, resist the urge to salt post-bake.)
- WATCH THE OVEN TEMP: 425°F is the magic number, but don’t crowd the tray. Use two racks if needed—overlapping chips steam instead of crisp. I once baked a full sheet at 375°F because my oven runs hot, and the result? Greasy, limp chips. Preheat for 10 minutes with the rack in the middle position.
- SKIP THE FRESH VINEGAR: Store-bought white vinegar works, but aged vinegar (3+ months old) adds depth. If you’re using fresh, simmer it for 5 minutes to mellow the harshness. (I was skeptical until I tried it—now I never go back to the stuff that burns your nose.)
Common mistakes when making perfect results
Uneven Slicing
Thickness is everything—anything thicker than ⅛-inch will turn out soft and doughy in the center. I’ve learned this the hard way after making chips that looked perfect but tasted like potato mash.
Use a mandoline slicer with a ⅛-inch blade for consistency, or if slicing by hand, cut the potatoes lengthwise into quarters first to create a flat surface. Stack slices and cut in batches for even thickness. 🔪
Skipping the Soak
That 30-minute cold water soak isn’t optional—it removes excess starch that would make your chips gummy. I once forgot this step and ended up with chips that stuck together like glue.
Drain and pat completely dry with paper towels before seasoning. Any lingering moisture will steam the chips instead of crisping them, and you’ll end up with sad, limp results.
Overcrowding the Pan
Piling chips too close together traps steam, making them soggy instead of crispy. Arrange slices in a single layer with ½-inch gaps between each. If your baking sheet is full, work in batches—this ensures proper air circulation and even browning.
I’ve had to re-bake entire batches because I was impatient and overcrowded them. Trust me, the extra 5 minutes waiting for the second tray to bake is worth it for perfect chips.
Ignoring the Rest Time
The 10-minute rest after tossing with seasoning lets the cornstarch adhere properly to the potato surfaces. Skipping this step means the seasoning will slide off during baking, leaving you with bland, unevenly flavored chips.
While resting, preheat your oven to 400°F—this ensures it’s ready when your chips are. Patience here makes all the difference between good chips and exceptional chips. ✨
Using the Wrong Oil
Not all oils are created equal—avocado oil has the highest smoke point (520°F), making it ideal for baking. Olive oil, on the other hand, burns easily and can turn your chips bitter. Lightly brush the baking sheet with oil, not the chips themselves.
Too much oil makes the chips greasy, while too little leads to uneven browning. A paper towel helps spread it evenly in a thin layer.
Burning the Chips
Watch closely in the last 5 minutes of baking—chips burn faster than you think! Remove them as soon as they’re golden brown, not dark brown. Overcooked chips taste bitter and lose their crispiness. If they’re not crispy enough, return them to the oven for 2-3 minutes at 400°F.
The key is timing: pull them out when they’re perfectly golden, not when you think they might be done. 🔥

Frequently asked questions
Can I use sweet potatoes instead of russets for this recipe?
Sweet potatoes work, but they won't be as crispy as russets due to their higher moisture content. If you try them, slice ⅛-inch thick, soak for 45 minutes (longer to remove moisture), and bake at 375°F instead of 400°F. Expect a slightly sweeter, less crispy result—better for dipping than snacking solo.
How do I make these chips spicier?
Add ½ teaspoon cayenne pepper or 1 teaspoon smoked paprika to the seasoning mix for heat. For extra kick, toss baked chips with 1 teaspoon chili powder before serving. Start with small amounts—you can always add more, but you can't remove spice once it's there!
Why did my chips turn out greasy?
Greasy chips usually mean you brushed too much oil on the baking sheet or the potatoes weren't completely dry. Use just 1 teaspoon oil per sheet (not tablespoon) and pat slices thoroughly after soaking. The oil should coat the pan lightly, not pool in it.
Can I make these chips in an air fryer?
Arrange dry, seasoned slices in a single layer in the air fryer basket (no oil needed). Cook at 375°F for 10-12 minutes, shaking halfway, until crispy. Air fryers work beautifully for smaller batches—just watch closely to avoid burning.
What's the best vinegar for extra tang?
White vinegar gives classic sharpness, but apple cider vinegar adds subtle sweetness that balances the salt. For maximum tang, use balsamic vinegar (reduce amount to ¼ cup)—it adds depth and caramel notes. Always use distilled vinegar for the most consistent results.
