Tostones are the savoury twice-cooked GREEN-plantain discs of Caribbean and Latin American kitchens — crisp, golden, and starchy rather than sweet — and the air fryer makes them in two stages, about 15 minutes total at 400 °F (204 °C). First air-fry 1-inch rounds of unripe green plantain for roughly 8 minutes until pale and soft enough to flatten, then smash each round flat with the bottom of a glass or a tostonera, spray the freshly smashed faces with oil, and return them to crisp into deep-golden, crackly-edged discs. Two non-negotiables: the plantains must be green and unripe (ripe yellow ones are the sweet maduros, which won't smash or stay savoury), and the oil has to hit the smashed face before the second cook or the discs bake pale and leathery instead of shattering crisp. Distinct from Plantains (ripe sweet maduros, cut into slices and cooked soft just once) — tostones are the green, savoury, smash-and-refry version, served with a garlic-mojo dip. 4 ways to finish: garlic-mojo, salt-and-lime, Cajun, and garlic-Parmesan.

How to tell it’s done

Two-stage cue: after the first ~8 minutes the rounds should be pale, softened, and tender enough to flatten without shattering — that's the moment to pull and smash them. After the smash and second cook the discs turn deep golden with crisp, crackly, lacy edges and a creamy-starchy centre. Rounds that crack apart when smashed went in too green-hard or weren't cooked soft enough first; discs that stay pale and bendy after stage two need more oil and a few more minutes.

Step-by-step method

1. 1

   Prep

   Bring ingredients close to room temperature. Light mist before the first cook, then spray the smashed faces well before the second cook. The crisp, crackly tostone surface comes entirely from oil hitting the freshly smashed, starchy face in the second round — dry discs just bake pale and leathery.

2. 2

   Season

   Season with Garlic-mojo (the benchmark): served with a garlicky citrus mojo dipping sauce (mashed garlic, olive oil, lime or sour-orange juice, salt) — the classic Caribbean way, with salt on the hot tostones., Salt-and-lime: simply showered with flaky salt and a hard squeeze of lime straight from the basket., Cajun: tossed with Cajun or adobo seasoning for a spicier, smokier savoury bite., Garlic-Parmesan: brushed with garlic oil and dusted with grated Parmesan in the last minute..

3. 3

   Load

   Arrange 2 green plantains, cut into about 1-inch rounds (roughly 16 pieces), smashed and cooked in single-layer batches for best convection airflow.

4. 4

   Cook

   Set the air fryer to 400 °F (204 °C) and cook for 15 minutes total, flipping once at 8 minutes.

5. 5

   Check & rest

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

6. 6

   Store

   Tostones are best eaten hot and fresh — they turn hard and dense as they cool. If needed, refrigerate up to 2 days and recrisp at 400 °F (204 °C) for 2–3 minutes; they will never be quite as crisp as the first cook. The pale first-cook rounds (before smashing) can be frozen, then smashed and finished from frozen later.

Watch out for

• !Use GREEN, unripe plantains — firm with no yellow or black. Ripe yellow plantains are too sweet and soft to smash into savoury tostones; they turn to mush instead of crisping (those are maduros — see Plantains).
• !Peel green plantains by scoring the tough skin lengthwise and prying it off in sections — it clings far harder than a ripe banana peel and won't slip off.
• !Soak the cut rounds in salted water for 10–15 minutes, then pat dry, for a crisper, better-seasoned tostone.
• !Smash gently with the flat of a glass, a plate, or a tostonera only after the first cook softens them — smashing raw-hard rounds just splits them apart.
• !Spray the smashed faces with oil before the second cook and keep them in a single layer — the crisp shatter comes from oil on the starchy surface, and crowded discs steam soft.

FAQ about tostones in an air fryer

What temperature should I cook tostones at in an air fryer?

Cook tostones at 400 °F (204 °C). The convection air at this temperature browns the exterior quickly without drying the centre.

How long do tostones take in an air fryer?

Tostones take 15 minutes total at 400 °F (204 °C). Flip the food once at 8 minutes so both sides cook evenly.

Do you need to flip tostones in an air fryer?

Yes — flip tostones once at 8 minutes. The side touching the basket grate develops a darker, more crusted surface; flipping evens out the cook so both sides match.

Do you need to preheat the air fryer for tostones?

Preheating is optional for tostones — 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.
