Air Fryer Salmon with Lemon and Garlic Butter: Step-by-Step Instructions

Recipe Variations

Swap the garlic butter for a herb butter made with dill, tarragon or chives for a different aromatic profile. Add a pinch of smoked paprika or chilli flakes to the butter if a subtle heat is desired. Replace the lemon juice with lime or a splash of white wine vinegar for a sharper acidity. For a Mediterranean twist, stir a teaspoon of capers and chopped olives into the butter before brushing. Use skinless fillets if you prefer a completely smooth texture; the skin can be left on for extra crispness. Substitute the salmon with trout or sea bass, adjusting the cook time by a minute or two depending on thickness. A gluten‑free version is inherent, as no flour or breadcrumbs are used. For a dairy‑free option, replace the butter with a plant‑based spread that contains a similar fat content.

Serving Ideas

Serve the salmon on a bed of wilted spinach or steamed green beans for a simple plate. A light couscous or quinoa salad with cucumber, mint and a lemon vinaigrette complements the fish without overwhelming it. Roasted new potatoes tossed in olive oil and rosemary make a heartier accompaniment. For a low‑carb option, pair with cauliflower rice seasoned with turmeric and black pepper. A dollop of Greek yoghurt mixed with chopped dill and a squeeze of lemon adds a creamy contrast. The dish also works well in a warm salad: flake the cooked salmon over mixed leaves, cherry tomatoes and red onion, then drizzle with the pan juices. If entertaining, arrange the fillets on a platter with lemon wedges and a sprinkle of parsley for a clean presentation.

Keeping It Fresh

Store any leftover salmon in an airtight container in the refrigerator for up to two days. Reheat gently in the air fryer at 150 °C for three minutes to avoid drying out the flesh. The garlic butter can be prepared a day ahead and kept covered in the fridge; bring it to room temperature before brushing. Lemon juice loses potency over time, so add it just before serving. Parsley wilts quickly; keep a small bunch in a glass of water in the fridge and chop as needed. Do not freeze the cooked fillets, as the texture becomes mushy on thawing. If you must freeze, do so before cooking: brush the raw fillets with butter, place on a tray, freeze solid, then transfer to a bag; cook from frozen adding two minutes to the air‑fry time.

Reader Questions Answered

Can I use frozen salmon fillets?

Yes, thaw them fully in the refrigerator before cooking; pat dry and follow the same steps, adding an extra minute if they are still cold.

What if my air fryer does not reach 190 °C?

Set the highest temperature available and extend the cook time by two to three minutes, checking the internal temperature.

Is it necessary to preheat the air fryer?

Preheating gives a more even sear and reduces total cooking time; skipping it may result in a softer surface.

Can I replace butter with oil?

You can use a high‑smoke‑point oil, but the flavour and richness of butter will be lost.

How do I know the salmon is cooked through?

Insert a probe into the thickest part; 60 °C indicates medium‑rare, 63 °C is fully cooked and safe.
