Quick answer
Air-fry two salmon fillets at 180–190°C for roughly 7–12 minutes, depending on thickness and starting temperature. Put skin-on fillets skin-side down and begin checking early. Cooked fish should be opaque and separate easily with a fork; follow packet advice and use a thermometer when extra certainty is needed.
Estimated air-fryer salmon times
| Fillet | Temperature | Estimated time | Doneness cue |
|---|---|---|---|
| Thin, 2cm | 180°C / 355°F | 7–9 min | Opaque; flakes at thickest point |
| Medium, 3cm | 185°C / 365°F | 9–11 min | Opaque; separates easily |
| Thick, 4cm | 180–190°C / 355–375°F | 11–14 min | Centre hot and opaque |
Two fillets and basket space
Choose fillets of similar thickness and leave a gap between them. If the basket is too small for both to lie flat, cook one at a time. Crowding slows cooking and softens the surface.
Skin-on versus skinless
Put skin-on salmon skin-side down; the skin protects the flesh and can crisp where air reaches it. Lightly oil the basket for skinless fillets to reduce sticking. There is usually no need to turn either type.
Temperature, preheating and timing
Use 180–190°C as a practical range. Preheat only if your model recommends it, and reduce your first check time when the basket is already hot. Fillet thickness, not just weight, determines how quickly the centre cooks.
Fresh versus frozen salmon
Defrosting in the fridge gives the most even result. Some frozen fillets can be air-fried from frozen, but they need longer and may cook less evenly; follow the packet and appliance instructions and check the centre carefully.
Responsible doneness guidance
The Food Standards Agency advises that cooked fish flesh should turn opaque and separate easily with a fork. A thermometer offers extra confidence, especially for thick or previously frozen portions. People who need to avoid undercooked fish should follow their clinician’s advice and cook it thoroughly.
Seasoning and resting
Brush with a little oil and try lemon pepper, dill, paprika, garlic or a thin honey-soy glaze. Add sweet glazes during the final few minutes to limit scorching. Rest the fillets for two minutes before serving.
Storage and reheating
Cool leftovers promptly and refrigerate within two hours. Eat within 48 hours or freeze. Reheat only once until steaming hot, using a lower air-fryer temperature and checking early to avoid drying the fish.

Frequently asked questions
Do I need to flip salmon in an air fryer?
Usually not. Skin-side down keeps the fillet stable and protects the flesh while hot air cooks the top.
Can I air-fry salmon from frozen?
Follow the packet if it permits cooking from frozen. It will take longer and needs a careful centre check; fridge-defrosted salmon cooks more evenly.
