I’ve always loved how salmon can transform from a simple cut of fish into a bold, flavorful dish with just the right seasoning. When I started experimenting with my air fryer, Cajun salmon quickly became a weeknight favorite. The crispy edges, juicy interior, and smoky-spicy kick of Cajun seasoning make it taste like something straight out of a restaurant, yet it’s ready in under 15 minutes.
For me, this recipe is all about balance—spice without being overwhelming, a touch of zest to brighten things up, and that irresistible tenderness that only salmon can bring. It’s a dish that looks impressive on the plate but is wonderfully simple to pull together, even on busy days. Trust me, once you try this air fryer version, you’ll keep coming back to it again and again.
What You Need To Make This Recipe
Salmon fillets: The star of the dish. Look for fresh, skin-on salmon if possible because the skin helps hold moisture and crisps beautifully in the air fryer. The natural richness of salmon pairs perfectly with bold Cajun flavors.
Cajun seasoning: This blend of paprika, garlic, onion, cayenne, oregano, and thyme brings smoky heat and savory depth. It’s what gives the salmon that punchy kick without requiring a lot of extra effort. You can use store-bought or mix your own at home.
Olive oil: A drizzle of olive oil ensures the spices stick to the salmon while also helping to achieve that golden, slightly crispy finish in the air fryer. It adds a touch of richness that complements the fish.
Lemon juice: A squeeze of fresh lemon brightens the dish and cuts through the richness of the salmon. It’s the little detail that makes each bite feel lighter and more balanced.
Salt and pepper: Though Cajun seasoning already packs flavor, a touch of salt and black pepper fine-tunes everything. Think of these as the supporting players that bring the entire dish together.
Ingredients List
- 2 salmon fillets (about 6 oz each, skin-on)
- 1 tablespoon Cajun seasoning
- 1 teaspoon olive oil
- 1 teaspoon fresh lemon juice
- ¼ teaspoon salt (optional, depending on seasoning blend)
- ¼ teaspoon black pepper
How to Make Air Fryer Cajun Salmon
Step 1: Prepare the salmon
Pat the salmon fillets dry with a paper towel to remove excess moisture. This helps the seasoning adhere and ensures a crispier finish once cooked.
Step 2: Season generously
Brush each fillet lightly with olive oil, then sprinkle Cajun seasoning over the top and sides. Add a little salt and pepper if needed, depending on how salty your seasoning blend is.
Step 3: Air fry to perfection
Place the fillets skin-side down in the air fryer basket, making sure they aren’t touching. Cook at 400°F (200°C) for 8–10 minutes, depending on thickness. The salmon should flake easily with a fork when done.
Step 4: Add the finishing touch
Once cooked, squeeze fresh lemon juice over the fillets just before serving. This final touch enhances the flavors and balances the smoky spice.
Tips for Making This Recipe
- Don’t overcrowd the air fryer basket—this ensures the salmon cooks evenly and gets that perfect crisp.
- Adjust cooking time depending on thickness; thinner fillets may be done in 7–8 minutes, while thicker ones may need 11–12 minutes.
- If you like extra heat, sprinkle a pinch more cayenne or red pepper flakes before cooking.
- For a lighter version, spray the salmon with cooking spray instead of brushing with oil.
- Pair it with sides like garlic green beans, roasted potatoes, or a fresh cucumber salad for a complete meal.
