Baked plantain chips with lime are thin rounds of green plantain tossed in oil and fresh lime juice, then baked at 190C/375F until the edges curl and crisp, about 22 to 25 minutes. No frying, no deep pot of oil to babysit. Just a sheet pan and a squeeze of lime at the end.
I’ve made these more times than I can count, and the one thing that trips people up is slicing too thick. Anything over 2mm and you get a chewy chip instead of a crisp one. A mandoline fixes that in about two minutes.
Green plantains are starchy, not sweet, so they act more like a potato chip here than a banana. Lime cuts through that starchiness and keeps them from tasting flat.
These sit right in the snack rotation for kids and adults alike, and they hold up fine packed in a lunch bag for a few hours.

- Lime keeps the starchy plantain flavor bright, not flat
- Naturally vegan and gluten-free for easy snacking
Ingredient Notes
- green plantains: Look for firm plantains with green to yellow-green peel. Ripe, black-peeled plantains will bake soft and caramelized instead of crisp.
- olive oil: A light or regular olive oil works best here. Avocado oil is a fine swap and handles the oven heat well.
- lime: Use fresh juice and zest for the brightest flavor. Bottled lime juice works in a pinch but tastes flatter.
- fine sea salt: Fine salt sticks to the oiled slices better than coarse kosher salt does.
- chili powder: Optional, but it adds a light kick. Swap in smoked paprika if you want the flavor without the heat.
Easy Homemade Baked Plantain Chips with Lime
Ingredients
Method
- Heat the oven to 190C / 375F. Line a 33 x 46 cm / 13 x 18 inch sheet pan with parchment paper.
- Cut the ends off each plantain, then score the peel lengthwise in 3 to 4 strips with a paring knife. Peel back the skin with your fingers, using the knife to help lift stubborn spots since green plantain peel doesn’t pull away as easily as a ripe banana.
- Slice the plantains crosswise into rounds 1.5 to 2mm thick using a mandoline. This step decides whether your chips end up crisp or chewy, so take your time here.
- Zest the lime into a large mixing bowl, then juice it into the same bowl. Add the olive oil, salt, and chili powder if using, and whisk to combine.
- Add the plantain slices to the bowl and toss with your hands until every slice is coated in the lime-oil mixture.
- Arrange the slices in a single layer on the sheet pan, leaving space between each one so they roast instead of steam.
- Bake for 12 minutes, then flip each chip with tongs. Bake another 10 to 13 minutes, until the edges are golden brown and curling.
- Remove from the oven and let the chips cool on the pan for 5 minutes. They crisp up further as they cool, so don’t judge them straight out of the oven.
- Transfer to a bowl and serve with extra lime zest on top if you like.
Notes
- Score the plantain peel with a knife before peeling; green plantains don’t peel like ripe bananas.
- Slice evenly at 1.5 to 2mm thick for consistent crisping.
- Don’t overlap slices on the pan or they’ll steam instead of crisp.
- Chips crisp more as they cool, so wait 5 minutes before tasting.
Tips for Success
- Slice plantains to 1.5 to 2mm thick with a mandoline for even crisping.
- Spread slices in a single layer with space between them so they roast instead of steam.
- Flip the chips halfway through baking so both sides dry out evenly.
- Let chips cool on the pan for 5 minutes before eating, since they crisp up more as they cool.
- Salt the chips right after tossing with oil so it sticks before baking.
Variations
- Swap lime for lemon and add a pinch of cumin for a smokier, earthier chip.
- Toss with chili powder and a touch of cayenne for a spicy version with real kick.
- Use ripe yellow plantains instead of green for a sweeter, softer chip with caramelized edges.
Storage and Reheating
Baked plantain chips with lime keep their crunch for about 2 to 3 days if you store them in an airtight container at room temperature. Skip the fridge, the moisture in there softens them fast.
If they lose their crispness, spread them on a sheet pan and warm at 150C/300F for 5 minutes. That dries them back out without burning the edges.
Freezing isn’t worth it here. Thawed plantain chips go soft and chewy, and there’s no fixing that in the oven.
Serving Suggestions
Baked plantain chips with lime work as a stand-in for tortilla chips wherever you’d normally reach for a bag. Scoop them through guacamole, black bean dip, or a chunky mango salsa.
For a full snack board, set them out with a Cuban-inspired mojo sauce, some queso fresco, and lime wedges on the side.
They also work as a crunchy side next to a bowl of black beans and rice or alongside grilled fish tacos.
FAQ
Why aren’t my baked plantain chips getting crispy in the oven?
Your slices are probably too thick or overlapping on the pan. Anything over 2mm traps steam and the chips turn chewy instead of crisp, and overlapping pieces do the same by trapping moisture. Slice with a mandoline, spread the pieces out, and let them cool on the pan for 5 minutes before judging, since they crisp up as they cool.
Can I use ripe yellow plantains instead of green ones for this recipe?
Yes, but the texture changes. Ripe yellow plantains have more sugar and moisture, so they bake softer and caramelize at the edges instead of turning shatter-crisp like green plantains do. They still taste good, just more like a baked chip than a crunchy one, and they brown faster in the oven.
How long do baked plantain chips with lime stay crisp after baking?
They stay crisp for about 2 to 3 days stored in an airtight container at room temperature. Skip the fridge since the extra moisture softens them fast. If they lose crunch, spread them on a sheet pan and warm at 150C/300F for 5 minutes to dry them back out.
What goes well with baked plantain chips with lime?
Guacamole, black bean dip, and a bright avocado kale lime smoothie all work well since the lime already ties into those flavors. They also make a good side next to grilled fish tacos or a bowl of rice and beans. For a snack board, add queso fresco and extra lime wedges on the side.
Are baked plantain chips with lime gluten-free and vegan?
Yes, this recipe is naturally gluten-free and vegan as written. It’s just plantains, olive oil, lime, and salt, with no dairy, eggs, or flour involved. If you add chili powder for extra kick, check the label since some blends include additives that aren’t always allergen-free.
What’s the difference between plantain chips and banana chips?
Plantain chips are savory and made from starchy green plantains, while banana chips are usually sweet, made from ripe bananas, and often fried or coated in sugar. Plantains hold their shape and crisp up in a hot oven, while ripe bananas turn soft and caramelized instead.
