This air fryer salmon with Dijon crust and fresh dill is a quick, flavorful way to get a restaurant-style fish dinner at home without turning on the oven. The mustard coating helps the topping cling, while the air fryer delivers a lightly crisp surface and a tender center.
Why This Air Fryer Recipe Works
Dijon mustard acts like edible “glue,” keeping the crust in place and seasoning the salmon at the same time. A little panko and olive oil encourage browning, so the top gets toasty without drying out the fish.
Fresh dill finishes the salmon with a clean, herby bite that cuts through the richness. Since air fryers heat fast and circulate air, you can get dinner on the table in under 20 minutes.
Ingredients You’ll Need
- 4 salmon fillets (about 6 oz each, skin-on or skinless)
- 1 1/2 tbsp Dijon mustard
- 1 tbsp mayonnaise (optional, helps the crust brown and stay creamy)
- 1 tsp lemon zest
- 1 tbsp lemon juice
- 1 clove garlic, finely grated (or 1/2 tsp garlic powder)
- 1/2 tsp kosher salt (plus more to taste)
- 1/4 tsp black pepper
- 1/2 cup panko breadcrumbs
- 1 1/2 tbsp olive oil (or melted butter)
- 2 tbsp fresh dill, chopped (plus more for serving)
- Optional: lemon wedges for serving
Salmon notes: center-cut fillets cook most evenly. If your fillets are very thin on one end, tuck that end under to slow it down.
How to Make Air Fryer Salmon with Dijon Crust and Fresh Dill in the Air Fryer
1) Preheat the air fryer to 390°F for 3 minutes. Lightly oil the basket or use air fryer parchment with holes.
2) Pat the salmon dry with paper towels. Season with salt and pepper.
3) In a small bowl, mix Dijon, mayonnaise (if using), lemon zest, lemon juice, and garlic. Spread a thin, even layer on the top of each fillet (not the skin side).
4) In another bowl, stir together panko, olive oil, and chopped dill. The crumbs should look evenly moistened, not soggy.
5) Press the panko mixture onto the mustard-coated side of the salmon, gently but firmly so it adheres.
6) Place salmon in the air fryer basket, crust side up, with space between pieces for airflow. Cook until the crust is browned and the salmon flakes easily.
7) Rest 2 minutes, then finish with extra fresh dill and lemon wedges if you like.
Air Fryer Time and Temperature
Cook at 390°F. Most 1-inch-thick fillets take 8–10 minutes.
- Thin fillets (3/4 inch): 7–9 minutes
- Thicker fillets (1 1/4 inch): 10–12 minutes
Doneness check: the salmon should flake with a fork and look opaque on the outside with a slightly deeper shade in the center. If the crust is browning faster than the fish is cooking, lower the temp to 375°F for the last couple minutes.
Tips for the Best Results
- Dry the surface well. Less moisture means better browning and a crust that sticks.
- Don’t overload the basket. Airflow is what crisps the panko.
- Use oil in the crumb mix. It helps the panko toast instead of staying pale.
- Keep the crust on top only. If crumbs fall to the bottom, they can burn.
- Rest briefly. Two minutes lets juices settle so the salmon stays moist when you cut into it.
If the crust won’t adhere, you likely need a slightly thicker Dijon layer or more pressure when applying the crumbs. If the top looks dry, add 1–2 tsp more oil to the panko next time.
Variations and Substitutions
- More tang: swap half the Dijon for whole-grain mustard.
- Gluten-free: use gluten-free panko or crushed gluten-free crackers.
- Extra crunch: mix 2 tbsp grated Parmesan into the panko.
- No mayo: skip it and add 1 tsp olive oil to the Dijon mixture for a smoother spread.
- Different herbs: parsley or chives work if you’re out of dill, but dill is the cleanest match with salmon and Dijon.
What to Serve With It
This salmon is great with simple sides that won’t compete with the Dijon and dill. Aim for something fresh, something starchy, or both.
- Air fryer asparagus or green beans with lemon
- Roasted baby potatoes or a quick rice pilaf
- Simple arugula salad with a light vinaigrette
- Steamed broccoli with a little butter and pepper

Storage and Reheating
Store leftover salmon in an airtight container in the refrigerator for up to 3 days. Keep lemon wedges separate so the crust doesn’t get soggy.
To reheat, place fillets in the air fryer at 350°F for 3–5 minutes, crust side up, until warmed through. If the crust starts to over-brown, lower to 325°F and extend the time slightly.

FAQ
Can I use frozen salmon in the air fryer for this recipe?
It’s best to thaw first so the Dijon and panko crust can stick. If you must cook from frozen, air fry the salmon plain for a few minutes until the surface thaws, then add the Dijon and crust and finish cooking.
Do I cook salmon skin-side down in the air fryer?
Yes. Place skin-on fillets skin-side down so the crust stays on top and the salmon is easier to lift out. The skin also acts as a barrier that helps keep the fish moist.
How do I keep the Dijon crust from blowing off?
Press the crumb mixture onto a full, even Dijon layer and avoid moving the fillets once they’re in the basket. Also make sure the panko is lightly oiled so it clumps slightly instead of staying dusty.
What temperature should salmon be cooked to?
Many home cooks pull salmon when it flakes easily and looks opaque on the outside, since it will carry over slightly as it rests. If you use a thermometer, follow your preferred doneness and food safety guidance for fish.
Can I make this with salmon portions of different sizes?
Yes, but cook the thicker pieces in the center of the basket and thinner ones toward the edges. You can remove thinner fillets early and keep them warm while the rest finishes.
