Seitan cooks in the air fryer in about 14 minutes at 375 °F (191 °C), shaken once at the halfway mark, until the cubes or strips are browned, firm, and crisp-edged. Seitan — 'wheat meat' made from vital wheat gluten — is dense, chewy, and very high in protein, and because store-bought (or from-scratch, pre-steamed) seitan is already cooked, the air fryer's job is to crisp and heat it rather than cook it through. Toss the pieces with a little oil, optionally a splash of soy or sauce, and give them room so every side browns. Unlike Tofu (mild pressed soybean curd) and Tempeh (fermented whole-soybean cake), seitan gets its meaty, chewy bite from wheat gluten itself — and crucially, that makes it the only one of the three that is NOT gluten-free, so it's off the table for anyone with celiac disease. 4 ways to make it: BBQ, teriyaki or soy-ginger, buffalo, and Cajun blackened.

How to tell it’s done

Done when the cubes or strips are browned and firm with crisp, chewy edges and heated through. Seitan is already cooked, so you're crisping and warming it rather than cooking raw protein — there's no internal temperature to hit. Shake the basket at the halfway mark so every side browns.

Step-by-step method

1. 1

   Prep

   Bring ingredients close to room temperature. Yes — toss the pieces with a little oil (and a splash of soy or sauce if you like) so the edges brown and crisp; bare seitan stays pale and dries out.

2. 2

   Season

   Season with BBQ: toss in barbecue sauce in the last few minutes for sticky, charred edges., Teriyaki / soy-ginger: a soy-ginger or teriyaki glaze for a stir-fry-style protein., Buffalo: toss in buffalo sauce after cooking for vegan buffalo 'wings' or bites., Cajun or blackened: a dry Cajun rub tossed on with the oil before cooking..

3. 3

   Load

   Arrange 8–10 oz of seitan, cut into cubes or strips, in a single layer; serves 2–3 for best convection airflow.

4. 4

   Cook

   Set the air fryer to 375 °F (191 °C) and cook for 14 minutes total, shaking once at 7 minutes.

5. 5

   Check & rest

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

6. 6

   Store

   Refrigerate cooked seitan airtight up to 4–5 days and re-crisp at 375 °F (191 °C) for 3–4 minutes. It also freezes well for up to 2–3 months; thaw before air-frying.

Watch out for

• !Seitan is NOT gluten-free — it's made almost entirely of wheat gluten, so never serve it to anyone with celiac disease or gluten intolerance. (This is the key difference from soy-based, gluten-free Tofu and Tempeh.)
• !Store-bought and from-scratch seitan are both already cooked — you're crisping and heating, not cooking raw protein, so go by browned firm edges rather than a thermometer.
• !Toss with oil and, if using, sauce — without it the surface stays pale and the edges turn leathery.
• !Cut even cubes or strips and keep them in a single layer with a halfway shake so every side crisps instead of steaming.
• !Add sugary sauces (BBQ, teriyaki) only in the last few minutes or after cooking — they scorch quickly in the dry heat.

FAQ about seitan in an air fryer

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

Cook seitan 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 does seitan take in an air fryer?

Seitan takes 14 minutes total at 375 °F (191 °C). Shake the basket once at 7 minutes so both sides cook evenly.

Do you need to shake seitan in an air fryer?

Yes — shake the basket once at 7 minutes. Loose pieces (seitan) 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 seitan?

Preheating is optional for seitan — 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.
