Roma tomatoes are the secret weapon here—their dense flesh holds up perfectly to slicing and frying. Grab the firmest ones from the produce section, avoiding any with soft spots. I always check the price per pound at Whole Foods or my local farmers market—they’re worth the extra cost for this recipe. For heirloom varieties, look for bright, even coloring and a slight give when gently squeezed. If you’re using beefsteak tomatoes, slice them against the grain for maximum crispiness. The key is consistency: aim for slices about 1/16-inch thick—use a mandoline if you’ve got one, but a sharp knife works too.
No avocado oil? Vegetable or canola oil works in a pinch, but avocado oil’s high smoke point keeps the flavor clean. Short on smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close. The cornstarch is optional but makes a world of difference for extra crunch—just toss the slices in it before frying. For a tangy kick, swap the lemon juice for lime juice. And if you’re feeling fancy, Trader Joe’s carries pre-grated nutritional yeast that’s perfect for this. The flaky sea salt should be the good stuff—Maldon if you’re splurging, or any high-quality flake salt from the grocery store’s baking aisle.
These chips are best served immediately after frying, but you can keep them warm in a 200°F oven for up to 15 minutes if you’re serving a crowd. For storage, let them cool completely, then layer between paper towels in an airtight container. They’ll stay crisp for 2-3 days at room temperature, though they’re best enjoyed fresh. Freezing? Not ideal—they’ll lose their satisfying crunch. I usually make a big batch and eat them all within the first day, but the leftovers make a great snack the next. Pair with salsa, guacamole, or just a sprinkle of the flaky salt for the ultimate snack experience.

Step-by-step instructions for tomato chips recipe
Here's how to transform simple garden tomatoes into restaurant-quality chips with perfect texture and bold flavor.
Prepare the Tomatoes for Perfect Slices
Cut the 4 whole fresh Roma tomatoes in half lengthwise and remove the seeds using a small spoon. This step is crucial—seeds can make your chips bitter and uneven. Pat each tomato half completely dry with the 4 sheets paper towels, pressing firmly to remove all moisture. Any lingering water will prevent crispiness during frying.
Slice each tomato half into ⅛-inch thick rounds, working quickly to prevent oxidation. You should get about 24 slices total. For even cooking, arrange the slices on a clean surface and lightly brush both sides with 1 tablespoon lemon juice. This acid touch helps preserve color and enhances the tomato's natural sweetness while preventing browning during prep.
Create the Flavor Coating
In a shallow bowl, combine 1 tablespoon cornstarch, 1 tablespoon nutritional yeast, 2 teaspoons sea salt, 1 teaspoon smoked paprika, 0.5 teaspoon garlic powder, and 0.25 teaspoon cayenne pepper. The nutritional yeast adds that savory umami depth while the spices create a complex flavor profile that stands up to the tomato's natural sweetness.
Gently toss each tomato slice in this dry mixture, pressing lightly to ensure even coating. Don't worry if some powder remains—this will burn off during frying, leaving behind just the perfect seasoning. Let the coated slices rest for 5 minutes while you prepare your frying station. This brief resting period helps the seasoning adhere better and prevents the slices from curling during cooking.
Fry in Small Batches for Optimal Crispiness
Heat 0.5 cup avocado oil in a deep skillet over medium heat until it reaches 350°F. Use a thermometer for accuracy—this temperature is critical for achieving that perfect balance between crispy exterior and tender interior. When the oil is ready, add 4-5 tomato slices at a time, being careful not to overcrowd the pan. Fry for 1-2 minutes per side until they turn golden brown and crisp.
Watch closely as the chips cook—they'll darken quickly. You're aiming for a deep golden color, not burnt edges. As each batch cooks, transfer the chips immediately to a paper towel-lined plate to drain excess oil. The residual heat will continue cooking them slightly, so don't leave them in the oil too long. Work in batches to maintain consistent oil temperature throughout the process.
Season and Serve Immediately
While the chips are still warm, sprinkle them generously with the 1 tablespoon flaky sea salt. The contrast between the crispy texture and the flaky salt crystals creates an irresistible sensory experience. Serve immediately while they're at their peak crunch. These chips will lose crispiness as they cool, so enjoy them straight from the fryer.
For the best results, arrange the chips on a wire rack set over a baking sheet to keep them crispy for longer. They'll maintain their perfect texture for about 15 minutes after frying. Pair with your favorite dipping sauce or enjoy them as-is—they're delicious enough to stand alone. The combination of smoky, garlicky, slightly spicy flavors with that satisfying crunch makes these chips truly special.
Pro Tips For Making Tomato Chips
- SLICE THINLY, EVENLY: Use a sharp knife and cut the tomatoes into 1/8-inch slices—no thicker, or they’ll turn soggy. I learned this the hard way when mine came out chewy instead of crisp. A mandoline helps, but if you’re doing it freehand, hold the tomato steady and go slow.
- PAT DRY, DON’T SKIP: After slicing, blot the tomatoes with paper towels—wet slices splatter like crazy and won’t crisp properly. I used to rush this, but now I give them a good press, especially the juicier ones. Less mess, better chips.
- HIGH HEAT, LOW TIME: Cook the chips in small batches—3-4 slices at a time—on medium-high heat in avocado oil. They’re done in 2-3 minutes max, or they’ll burn before crisping. Crowd the pan, and you’ll regret it.
- SALT AFTER CRISPING: Sprinkle sea salt right after removing the chips from the oil—it sticks better and won’t make them greasy. I used to salt before frying, and the seasoning just vanished. Same goes for the smoked paprika and garlic powder—wait until they’re golden.
Dietary considerations for tomato chips
Gluten-Free Assurance
The beauty of these tomato chips is they're naturally gluten-free—no flour, no grains, just pure tomato and seasonings. The cornstarch coating is optional, but if you skip it, you're still safe.
Always double-check your spices for cross-contamination warnings if you have severe gluten sensitivity. I've tested this recipe with Penzeys Spices brands, which are certified gluten-free, so you can enjoy these worry-free. 🌾
Low-Fat Options
For a lighter version, skip the frying entirely and bake your chips instead. Toss the seasoned tomato slices with 1 teaspoon avocado oil spray (or just a light mist of water) and bake at 275°F for 1.5-2 hours on parchment paper-lined baking sheets.
Flip halfway through for even drying. These baked chips won't be as crispy as fried versions but still deliver satisfying texture with far less fat. 🔥
Oil-Free Adaptation
Want to eliminate all oil? Try the dehydrator method—slice tomatoes ⅛-inch thick, brush lightly with lemon juice, then arrange on dehydrator trays. Run at 135°F for 6-8 hours until completely dry and crisp. The result is a chewy, leathery chip with concentrated tomato flavor.
This method works best with Roma tomatoes due to their firm flesh. Store in airtight containers for up to 2 weeks—they'll soften slightly but remain edible. ✨
Vegan-Friendly
This recipe is already 100% plant-based, making it perfect for vegan diets. All ingredients are naturally vegan, including the nutritional yeast which provides that cheesy umami flavor. For extra protein, sprinkle with hemp seeds before serving.
I've even seen people add vegan parmesan as a topping—just a light dusting enhances the savory profile without overpowering the tomato. 💚
Allergy Considerations
Watch for potential allergens in your seasoning blend. Nutritional yeast is typically safe, but check labels if you have yeast sensitivities. For nut-free kitchens, ensure no cross-contamination with tree nuts. If you're avoiding all corn products, substitute the cornstarch with arrowroot powder for the coating.
Always read labels on spices—some brands process in facilities that handle soy or dairy. I keep a Penzeys Allergy-Friendly Spice Kit on hand for these recipes. 🚫
Low-Sodium Adaptation
Reduce the sea salt to 1 teaspoon total (half the original amount) and boost flavor with extra garlic powder (1 teaspoon) and smoked paprika (1.5 teaspoons). For a completely salt-free version, omit the salt entirely and use everything bagel seasoning instead—it provides complex flavor without sodium.
Taste as you go, as tomatoes vary in natural saltiness. 🧂

Frequently asked questions
Can I use any tomato variety for these chips?
Roma tomatoes work best because their dense flesh holds up perfectly to slicing and frying. For heirloom or beefsteak varieties, slice against the grain for maximum crispiness. Avoid overly watery tomatoes like cherry varieties—they won't crisp properly.
What's the secret to getting them extra crispy?
Pat slices completely dry with paper towels and use cornstarch before frying. Maintain oil at 350°F and fry in small batches—overcrowding lowers temperature and makes them greasy.
Can I bake these chips instead of frying?
Toss seasoned slices with 1 tsp oil spray and bake at 275°F for 1.5-2 hours on parchment paper. Flip halfway for even drying. They'll be less crispy but still delicious with 80% less fat.
Why did my chips turn out soggy?
Most likely from moisture—either tomatoes weren't dry enough or oil temperature was too low. Always pat slices thoroughly and use a thermometer to maintain 350°F oil. Work in batches to keep temperature stable.
How do I store leftover chips?
Keep them crispy by storing in an airtight container between paper towels. They'll stay fresh for 2-3 days at room temperature. For longer storage, freeze for up to 1 week (though texture may soften slightly).
