Air Fryer Salmon (Easy & Flaky)
Air fryer salmon needs five minutes of prep and no marinade. Dijon mustard holds the seasonings against the fish during cooking. I make this after work when chopping vegetables feels like another assignment. The supplied nutrition lists 34g protein and 250 calories per serving.
Why This Works
A thin mustard layer spreads flavor across the salmon without complicated preparation. Paprika adds color, while garlic powder seasons evenly without any mincing. Salt and pepper finish the seasoning with ingredients already common in kitchen cabinets. A light olive oil spray coats the surface before cooking.
The ingredient list stays short, and nothing needs advance marinating. Each filet gets its own coating, making four portions easy to divide. The air fryer handles the cooking while you organize simple sides. Choose similarly thick pieces so each batch cooks more evenly.
The Short Version
The supplied timing lists 5 minutes prep, 15 minutes cooking, and 20 minutes total. However, the instructions require two consecutive batches of 8 to 10 minutes. That means 16 to 20 minutes cooking, plus preparation and any preheating time. Allow extra time rather than treating the listed total as guaranteed.
First, preheat the appliance and dry the salmon with paper towels. Spread Dijon across the tops, then add the seasonings and oil spray. Cook two filets, then repeat with the remaining pair. Check each batch separately, since filet thickness affects when the fish finishes.
What You Need
Seven ingredients cover the fish, coating, and seasoning. Measure the spices before handling the raw salmon to keep preparation organized. Use the quantities below for the original four servings. Optional serving ideas and substitutions appear separately later in this post.
- 4 (6-ounce) salmon filets
- 2 tablespoons Dijon mustard
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- 1/2 teaspoon kosher salt
- 1/4 teaspoon freshly ground black pepper
- Olive oil spray
How to Make It
Leave space between the filets so hot air can circulate around them. Start checking at 8 minutes instead of automatically using the longest cooking time. Check the thickest part reaches 145°F with a food thermometer.
- Preheat the air fryer to 400°F (200°C) and pat the salmon filets dry with paper towels.
- Spread an even, thin layer of Dijon mustard over the top of each salmon filet.
- Season the filets with the kosher salt, black pepper, garlic powder, and paprika, then lightly coat the tops with olive oil spray.
- Place two salmon filets in the air fryer basket and cook for 8 to 10 minutes, until the fish flakes easily with a fork.
- Repeat the cooking process with the remaining two salmon filets.
How to Serve It
Microwave rice and steamed vegetables keep the side dishes straightforward. Start them during cooking so everything finishes close together. Green beans, broccoli, or a bagged salad work alongside the seasoned fish. Serve the salmon with its coated surface facing up.
For a lighter plate, pair one filet with cucumber and tomato salad. For a larger meal, add rice or potatoes alongside the vegetables. The supplied nutrition applies to the salmon recipe without these side dishes. Account for toppings and sides separately when tracking your meal.
Leftovers and Storage
Refrigerate cooked salmon for up to 4 days at 40°F or below. Use shallow, sealed containers and refrigerate within 2 hours of cooking. Reduce that window to 1 hour when temperatures exceed 90°F. Store salad and other crisp sides separately from the fish.
To reheat, place one portion in a microwave-safe dish with a water splash. Cover loosely and heat at half power for 60 seconds. Continue in 30-second intervals until the salmon reaches 165°F throughout. Check between intervals because repeated heating can dry the edges.
Quick Notes
Even thickness and clear spacing matter more than matching a timer exactly. Check both filets because pieces can finish at different times. Keep the second batch refrigerated while the first batch cooks.
- Pat the salmon dry before spreading mustard; excess surface moisture thins the coating.
- Avoid crowding the basket or stacking filets, which interferes with air circulation.
- Compare fresh and frozen salmon prices per pound; package sizes can disguise differences.
- Measure all seasonings together beforehand to make coating the four portions faster.
- Thaw frozen filets in the refrigerator before following these cooking instructions.
- Swap smoked paprika for regular paprika in the same amount for smoky flavor.
Easy Swaps
These optional substitutions change the original recipe listed above. Start with one adjustment so the flavor difference stays easy to judge. Different products can change the supplied nutrition values.
- Use 1 teaspoon smoked paprika instead of regular paprika for a smoky coating.
- Replace Dijon with 2 tablespoons whole grain mustard for a textured topping.
- Use 1 teaspoon onion powder instead of garlic powder for different seasoning.

Common Questions
Can I use frozen salmon?
Yes, but thaw it first in the refrigerator according to package directions. Pat the thawed fish dry before adding mustard. The supplied cooking instructions do not cover salmon cooked directly from frozen.
Do I need to flip the salmon?
No flipping step appears in this recipe. Keep the mustard coating facing up during cooking. Lift each cooked portion carefully with a spatula to limit breaking.
Can all four filets cook together?
The supplied method uses two batches of two filets. A larger basket may accommodate four with clear space around each. Only combine batches when the fish fits comfortably in one layer.
Dry the fish, spread the mustard thinly, and leave room in the basket. Plan for both batches before starting your sides. Check doneness early so the salmon stays tender.
