Gluten-Free Air Fryer Fish

Plain fish fillets are naturally gluten-free and cook exceptionally well in the air fryer — no modification needed. Salmon: 400°F for 10–12 minutes (1-inch thick fillet), internal 145°F. Skin becomes crispy when placed skin-side down. Cod: 400°F for 12–14 minutes for a thick fillet, flakier and lighter than salmon. Tilapia: 400°F for 10–12 minutes, very quick cooking. Sea bass: 400°F for 10–12 minutes, crispy skin, tender flesh. Shrimp/prawns: 400°F for 6–8 minutes — naturally GF and very fast. All plain fish fillets need only a light oil spray, salt, pepper, and perhaps lemon zest and garlic powder. Serve with a naturally GF side: lemon wedges, wilted spinach, air fryer asparagus, or tartar sauce (check the label — most are GF).

Traditional beer batter uses wheat flour, but a rice flour and sparkling water batter is a convincing GF substitute. Mix 100g rice flour, 100g tapioca starch, 1 tsp baking powder (GF certified), ½ tsp salt, and enough sparkling water to make a thick, pourable batter. Dip dried fish fillets (cod is classic), let excess drip off, place carefully in the air fryer. Spray with cooking oil. Cook at 390°F for 12–15 minutes, flipping very carefully at the halfway point (battered fish is fragile). The batter puffs and crisps around the fish. For a lighter GF crumb coating: dip in GF flour, then egg, then seasoned GF breadcrumbs. This method is more reliable in the air fryer than wet batter — the wet batter can drip and pool in the basket, creating uneven results.

The challenge with air fryer fish and chips is that potato wedges take longer to cook than fish. Stagger the cooking to get both to the table simultaneously. Start with potato wedges: cut medium potatoes into 8 wedges, toss with oil, salt, and garlic powder. Cook at 390°F for 20–25 minutes, shaking at 10 and 18 minutes. At the 5-minute-remaining mark on the wedges, add a small tray or foil parcel of fish to the other side of the basket (in a larger dual-zone air fryer, this is much easier — cook wedges in zone 1 at 390°F for 25 min, fish in zone 2 at 400°F for the last 12–15 min). Alternatively, cook wedges fully, wrap in foil to keep warm, then cook fish. The total cook time from start to plate is 30–35 minutes.

Tartar sauce: most store-bought tartar sauces are GF but check for malt vinegar — Heinz and Hellmann's varieties are typically safe. Alternatively make your own: mayonnaise, capers, cornichons, dill, lemon juice. Lemon wedges: always GF, brighten any fish dish. Mushy peas (UK classic): dried marrowfat peas soaked overnight then slow-cooked — naturally GF, no thickeners needed. Coleslaw made with mayonnaise: GF, refreshing alongside battered fish. Chips/wedges: naturally GF when made from plain potatoes — check frozen varieties for added wheat starch. Minted peas (frozen): naturally GF, quick to cook alongside. Avocado and tomato salsa: naturally GF, works as a fresh modern accompaniment for air fryer salmon or sea bass.
