Plantain chips are paper-thin crisps of green plantain — the Latin and Caribbean snack also called mariquitas or platanitos — and the air fryer makes them in about 12 minutes at 375 °F (191 °C) with a shake at the halfway mark. Slice peeled green plantains as thin as you can (a mandoline is the trick to even, shatter-crisp chips), toss them in just a little oil, spread them in a single layer, and cook until golden and curled. Two things matter most: the plantains must be green and unripe so they crisp rather than soften, and the slices must be thin and even, since thick pieces stay chewy in the middle. Like all chips they firm up as they cool, so pull them while just golden rather than waiting for a snap in the basket. Distinct from Tostones (thick rounds cooked, smashed flat, and crisped a second time) and Plantains (ripe, sweet maduros cooked soft) — plantain chips are the thin, savoury, crunchy snack form. 4 ways to season: sea-salt, garlic, chili-lime, and cinnamon-sugar.

How to tell it’s done

Done when the chips are golden, curled at the edges, and dry — they firm into a hard crisp as they cool, so pull them once they look golden and stop steaming rather than waiting for a snap in the basket. Pale, bendy chips need more time; chips browning unevenly were sliced too thick or unevenly. A few darker edges are fine, but pull before any go deep brown (they turn bitter).

Step-by-step method

1. 1

   Prep

   Bring ingredients close to room temperature. Toss the slices in just a teaspoon or two of oil to coat lightly, or mist them — thin chips need very little. Too much oil makes them greasy and slow to crisp; too little and they bake dry and powdery. Salt straight out of the basket while hot.

2. 2

   Season

   Season with Sea-salt (the benchmark): tossed with fine salt the moment they come out — the classic mariquita / platanito., Garlic: dusted with garlic powder and salt for a savoury, snackable chip., Chili-lime: hit with chili powder, lime zest, and salt for a tangy-spicy version., Cinnamon-sugar: the sweet variant — tossed in cinnamon-sugar for a dessert chip..

3. 3

   Load

   Arrange 2 green plantains, peeled and sliced paper-thin (about 1/16 inch), cooked in single-layer batches for best convection airflow.

4. 4

   Cook

   Set the air fryer to 375 °F (191 °C) and cook for 12 minutes total, shaking once at 6 minutes.

5. 5

   Check & rest

   Check the visual doneness cue and serve immediately for best texture.

6. 6

   Store

   Cool completely, then store in an airtight container at room temperature up to 4–5 days — sealed away from humidity they stay crisp. If they soften, re-crisp at 350 °F (177 °C) for 1–2 minutes. Don't refrigerate; the moisture turns them chewy.

Watch out for

• !Use GREEN, unripe plantains — firm with no yellow. Ripe yellow plantains are too sweet and soft to crisp into chips (those are the maduros at Plantains).
• !Slice paper-thin and even, ideally on a mandoline — about 1/16 inch. Thick or uneven slices stay chewy in the middle while the edges scorch.
• !Peel green plantains by scoring the tough skin lengthwise and prying it off — it clings far harder than a ripe banana peel.
• !Single layer with minimal overlap so the slices crisp instead of steaming and fusing.
• !They firm up as they cool, so pull them while just golden — over-browning turns them bitter.

FAQ about plantain chips in an air fryer

What temperature should I cook plantain chips at in an air fryer?

Cook plantain chips at 375 °F (191 °C). The convection air at this temperature cooks the food gently — higher temperatures dry it out or scorch the surface.

How long do plantain chips take in an air fryer?

Plantain chips take 12 minutes total at 375 °F (191 °C). Shake the basket once at 6 minutes so both sides cook evenly.

Do you need to shake plantain chips in an air fryer?

Yes — shake the basket once at 6 minutes. Loose pieces (plantain chips) settle into the basket and the bottom layer stays pale unless you redistribute them halfway through.

Do you need to preheat the air fryer for plantain chips?

Preheating is optional for plantain chips — most modern air fryers reach temperature in under 2 minutes and the food's total cook time already accounts for the ramp-up. If you do preheat, reduce the total time by 1–2 minutes and check earlier than usual.
