A whole branzino cooks in the air fryer in about 14 minutes at 400 °F (204 °C), flipped once at the halfway mark, until the skin is crisp and the flesh flakes from the backbone at 145 °F (63 °C). Branzino — European or Mediterranean sea bass — is a lean, mild, sweet white fish that's almost always cooked whole, and the air fryer's dry convection crisps the skin beautifully while keeping the flesh moist. Scale and gut it (or buy it that way), pat it bone-dry, score the skin, oil it, and stuff the cavity with lemon and herbs. This is the whole-fish counterpart to Sea Bass, which on this site is the thick black or Chilean sea bass fillet — branzino is leaner and milder and served on the bone, where sea-bass fillet is buttery and boneless. It cooks much like Whole Trout (another whole fish, but oilier and earthier) and is leaner than oily frozen salmon. 4 ways to make it: classic lemon-herb, Mediterranean, Asian, or simple salt-and-citrus.

How to tell it’s done

Done when the skin is crisp and browned and the flesh at the thickest part behind the head is opaque white and flakes cleanly from the backbone. The eye turns opaque and the fins crisp. Flip the whole fish once, gently, with a wide spatula so both skins crisp without tearing.

Internal temperature: 145 °F / 63 °C. Always verify with an instant-read thermometer.

Step-by-step method

1. 1

   Prep

   Bring ingredients close to room temperature. Yes — rub the skin and cavity with olive oil so the skin crisps and doesn't stick, and so the seasoning adheres. Bare skin sticks to the basket and tears on the flip.

2. 2

   Season

   Season with Classic lemon-herb: lemon slices, parsley, and thyme tucked in the cavity with salt and olive oil., Mediterranean: garlic, oregano, cherry tomatoes, and a splash of white wine or olive oil., Asian: soy, ginger, scallion, and sesame, finished with a drizzle of hot oil., Simple salt-and-citrus: just olive oil, flaky salt, and lemon or orange to let the fish shine..

3. 3

   Load

   Arrange one whole branzino (about 1 lb / 450 g, scaled and gutted) per 1–2 people; a basket fits one fish, an oven-style air fryer fits two for best convection airflow.

4. 4

   Cook

   Set the air fryer to 400 °F (204 °C) and cook for 14 minutes total, flipping once at 7 minutes.

5. 5

   Check & rest

   Verify the internal temperature reaches 145 °F / 63 °C and rest 2–3 minutes before serving.

6. 6

   Store

   Best eaten fresh and crisp. Refrigerate leftover picked meat airtight up to 2 days; gently reheat at 320 °F (160 °C) for 2–3 minutes, though the skin won't re-crisp. Don't freeze cooked whole fish — the delicate flesh turns mushy.

Watch out for

• !Buy it scaled and gutted, then pat the skin bone-dry inside and out — wet skin steams and won't crisp, and any leftover scales make the skin unpleasant.
• !Score the skin with 2–3 shallow diagonal cuts on each side so heat reaches the centre evenly and the skin doesn't curl.
• !It is delicate — flip only once, with a wide spatula, and lift the whole fish from underneath; rushing the flip tears the skin and the fillet.
• !Watch for fine pin bones along the lateral line when eating; the flesh lifts off the backbone in two clean fillets once cooked.
• !Don't overcook — at 145 °F (63 °C) the flesh just flakes; a couple of minutes past that and lean branzino dries out.

FAQ about branzino in an air fryer

What temperature should I cook branzino at in an air fryer?

Cook branzino at 400 °F (204 °C). The convection air at this temperature browns the exterior quickly without drying the centre.

How long does branzino take in an air fryer?

Branzino takes 14 minutes total at 400 °F (204 °C). Flip the food once at 7 minutes so both sides cook evenly.

Do you need to flip branzino in an air fryer?

Yes — flip branzino once at 7 minutes. The side touching the basket grate develops a darker, more crusted surface; flipping evens out the cook so both sides match.

Do you need to preheat the air fryer for branzino?

Preheating is optional for branzino — most modern air fryers reach temperature in under 2 minutes and the food's total cook time already accounts for the ramp-up. If you do preheat, reduce the total time by 1–2 minutes and check earlier than usual.

What internal temperature is branzino safe to eat?

Branzino should reach an internal temperature of 145 °F (63 °C) measured at the thickest point with an instant-read thermometer. Visual checks alone are not a reliable substitute for protein — always confirm with a probe.
