Air fryer salmon can be kept moist and tender by following three expert tips: reducing packet cooking times by around 20%, cooking the fish skin-side down, and matching fillet sizes. Julian Klenda, seafood expert at Maine Lobster Now, said packet instructions are often the reason salmon comes out dry.
Why packet timing fails in an air fryer
Klenda said: "Packet instructions are written for one type of oven, and air fryers just don't behave in the same way." He added that most people don't realise this is why their salmon keeps coming out dry, even when they have followed the cooking time exactly.
The oven timing printed on packaging is typically intended for a conventional or fan-assisted oven. In an air fryer, the heating element sits closer to the food and circulates hot air rapidly, drawing moisture away from the salmon's surface. A fillet can brown and begin to dry out around the edges before the full cooking time has passed.
Klenda advised: "As a starting point, reduce the stated oven time by around 20% and begin checking the salmon several minutes before you expect it to be ready." He also recommended placing fillets in a single layer with space between them and checking the thickest part rather than judging by the browned surface.
Positioning and fillet sizes matter
Fillet positioning is another common error. Placing salmon skin-side down shields the flesh from the direct blast of hot air beneath, producing a more consistent result. Skin-side up browns the top more quickly, which can make the fish appear ready before the centre has finished cooking.
Klenda also said: "If you cook fillets of noticeably different sizes together, do not expect them to be ready at the same time." He advised giving thickest pieces a short head start or removing thinner fillets earlier instead of leaving everything in the basket until the largest piece is done.
Arrange the salmon in a single layer and check each piece individually. For tapered fillets, folding the thin end underneath can prevent it from becoming dry and brittle while the thicker centre finishes cooking.
