Crispy Air Fryer Salmon with Lemon Herb Crust

This version uses a light mayo-mustard binder and a crisp panko topping, so the crust turns golden without drying out the salmon underneath.

Crispy air fryer salmon with a lemon herb crust served on a neutral plate.

This recipe works best with thick centre-cut fillets and a topping that is pressed on firmly rather than loosely scattered. The mayo helps the crumbs cling, the lemon and dill keep it fresh, and the air fryer gives you a crisp top without needing to flip the fish.

Worth Knowing Before You Cook

Pat the salmon very dry before you start, then keep the topping on the flesh side only. A thin binder layer helps the crumbs stay put, and a light spray of oil on top makes the crust colour more evenly instead of drying out.

Ingredients
  

The Fish
  • 2 Atlantic salmon fillets about 150 g each, centre-cut, skin-on
The Binder
  • 1 tbsp Kewpie mayonnaise
  • 1 tsp Dijon mustard
The Lemon Herb Crust
  • 1/2 cup panko breadcrumbs
  • 1 tbsp lemon zest
  • 1 tbsp fresh dill finely chopped
  • 1/2 tsp garlic powder
Seasoning
  • 1/2 tsp sea salt
  • 1/4 tsp white pepper

Equipment

  • Air Fryer
  • Paper towels
  • Small bowl
  • Shallow bowl or plate
  • Non-Aerosol Oil Mister
  • Instant-read thermometer (optional)

Method
 

  1. Pat the salmon skin and flesh completely dry with paper towels. Dry fish helps the crust adhere and crisp better.
  2. Season the fillets lightly with sea salt and white pepper.
  3. Mix the Kewpie mayonnaise and Dijon mustard in a small bowl.
  4. Brush a thin, even layer of the mayo-mustard mixture over the top and sides of the salmon, but not the skin.
  5. In a shallow bowl, mix the panko, lemon zest, dill, and garlic powder.
  6. Press the salmon binder-side down into the crumb mixture, then use your hand to press the crust gently but firmly into place.
  7. Keep the salmon chilled until you are ready to cook so the fish stays tender while the topping browns.
  8. Place the salmon in the air fryer basket skin-side down, leaving about 2 cm between the fillets so the sides do not steam.
  9. Spray the crumb topping lightly with oil so it toasts and crisps more evenly.
  10. Cook at 200°C (400°F) for 7 to 9 minutes, until the crust is golden and the salmon is just cooked through.
  11. For a medium-rare centre, remove the salmon at about 52°C (125°F) internal temperature. If not using a thermometer, the fish should flake at the thickest part while still looking slightly translucent in the centre.
  12. Let the salmon rest in the basket for 2 minutes before serving so the crust can set.

Notes

Cooking the salmon with the skin on helps shield the bottom from direct heat, even if you do not plan to eat the skin.
If using frozen salmon, thaw it fully and dry it very well before adding the binder and crust.
Regular breadcrumbs can work, but panko gives the lightest and crispest texture.
If the crust is browning too quickly, lower the temperature slightly and add a little extra time.
For a lower-carb variation, crushed pork rinds can replace the panko.

Why Air Fryer Salmon Works So Well

Air fryer salmon works especially well when the top is coated rather than plain. The hot circulating air toasts the panko quickly, while the skin underneath helps shield the fish from direct contact with the basket. The result is a crisp, lemony crust on top and salmon that still stays tender in the centre.

  • Patting the salmon very dry is the most important step for a crisp topping.
  • A thin mayo-mustard layer helps the crust stick and brown more evenly than oil alone.
  • A quick mist of oil over the crumbs helps them turn golden instead of pale and dry.

Pro Tips

  • Keep the skin on, even if you do not plan to eat it. It protects the underside of the salmon as it cooks.
  • Leave a little space between the fillets so the sides roast instead of steaming.
  • If your air fryer runs hot, start checking at 7 minutes or drop the heat slightly to 195°C (385°F).
  • For a fully cooked centre, cook until the thickest part reaches 63°C (145°F), or until the flesh is opaque and separates easily with a fork. For a softer centre, start checking earlier and cook to your preferred doneness.

What Can Go Wrong

  • If the crust will not stay on: the binder layer was too thick or the crumbs were not pressed on firmly enough. Use a thin coating and press the topping into place.
  • If the topping colours too fast: your air fryer runs hot or the crumbs were too close to the element. Lower the heat slightly and check earlier.
  • If the salmon turns dry: it stayed in too long after the centre was done. Start checking at 7 minutes and pull it once it flakes easily at the thickest part.

Storage & Reheating

Store leftover salmon in an airtight container in the fridge for up to 2 days. Let it cool before sealing so the topping stays in better shape.

To reheat, return it to the air fryer at 180°C (355°F) for 2 to 3 minutes, just until warmed through and re-crisped on top. Avoid the microwave if you want to keep the crust crisp.

FAQ

Can I use frozen salmon?

Yes, but thaw it completely first and pat it exceptionally dry. Any lingering surface moisture will turn to steam and make it harder for the crust to stay crisp.

Why is my crust not crisping?

Usually because the salmon was still damp, the crumb topping was not pressed on well, or the top was not lightly sprayed with oil before cooking.

Can I use a different fish?

Yes, but timing will vary with thickness. Cod can work well with a similar topping, while thinner fish will need less time and a gentler check from about 5 minutes.

What I Used

The tools that make this recipe work consistently. Affiliate links — see disclosure.

Instant-Read Thermometer

Check the thickest part of the fillet rather than relying on colour or cooking time alone. For fully cooked salmon, aim for 63°C (145°F). See our recommended instant-read thermometer →

Reusable Silicone Liner — Optional

A properly fitted silicone liner can make cleanup easier when cooking oily fillets. It may slightly reduce airflow beneath the salmon, so cook directly on the basket when maximum underside browning matters. See our recommended silicone air fryer liners →

Refillable Non-Aerosol Oil Sprayer

A light, even mist helps the surface brown without leaving pools of oil on the fillets. Use plain cooking oil and follow the care instructions for your air fryer basket. See our recommended oil sprayer →

Ninja Air Fryer Max XL

This is the medium basket-style model used for the recipe. Its basket fits two centre-cut fillets in a single layer, although another similarly sized air fryer can also work. Read our full Ninja Air Fryer Max XL review →
