Air Fryer Salmon: Times by Thickness & How to Tell It’s Done

Quick answer: 180°C (350°F) for 10–12 minutes depending on thickness, skin-side down if skin-on. Salmon overcooks fast, so check a minute or two early the first time you try a new fillet size.

Why Salmon Needs a Lighter Touch

Salmon is more forgiving than white fish, but far less forgiving than chicken — the window between “perfectly flaky” and “dry and chalky” is narrow. Thickness varies a lot between fillets, which is the main reason a single fixed time doesn’t work well here.

Step-by-Step Method

1. Pat the fillet dry and brush lightly with oil.
2. Season simply — salt, pepper, and a squeeze of lemon is hard to beat. Garlic, dill, or a light soy-honey glaze all work well too.
3. Place skin-side down if the skin is on — this protects the flesh from direct heat and helps the skin crisp.
4. Air fry at 180°C (350°F): 8–10 minutes for a thin fillet (under 2cm), 10–12 minutes for an average fillet (2–3cm), 13–15 minutes for a thick centre-cut piece.
5. It’s done when it flakes easily with a fork and is opaque throughout, or hits an internal temperature of 50–52°C for medium (still slightly translucent in the centre) or 60°C for well done.

Skin On or Off?

Skin-on holds together better in the air fryer’s airflow and can crisp up nicely if the basket is preheated. Skinless is easier if you’re not a fan of the texture, but it’s more prone to sticking — a light oil coating and preheating both help.

Cooking From Frozen

Salmon can go straight from frozen — add roughly 50% to the cook time and check earlier than you’d expect, since frozen fillets vary more in how they cook through.

Frequently Asked Questions

How do I know when salmon is actually done without cutting it open?

Press gently with a fork — it should flake easily and look opaque rather than glassy. If you have a thermometer, the Doneness Checker walks through both the visual and temperature cues.

Why did my salmon stick to the basket?

Usually not enough oil, or placing it in before the basket was properly preheated. A light oil coating on both the fish and the basket helps.

Can I cook salmon with the skin facing up?

You can, but skin-side down generally gives better results — it protects the delicate flesh and gets a crispier result on the skin itself.
