Cajun Blackened Salmon (Air Fryer Recipe)

This is the recipe I turn to when I want big, bold flavor fast — no cast iron skillet required. Thanks to the air fryer, you get that perfect blackened crust without the smoky kitchen. The exterior is rich with Cajun spice and just the right amount of caramelization, while the inside stays buttery and moist.

This salmon is the definition of weeknight-friendly with weekend-worthy flavor. In less than 10 minutes, you’re biting into spicy, crisp-edged salmon that tastes like it came from your favorite New Orleans bistro.

And to cool things off? I love serving it with a creamy avocado-lime sauce that balances the heat beautifully. It’s fast, fresh, and full of contrast.

🌿 Ingredients Overview

• Salmon fillets: Try to use center-cut pieces that are about 1 inch thick.
• Olive oil: Helps the spice mix stick and crisps the surface.
• Cajun seasoning: Use your favorite blend or make your own.
• Brown sugar: Just a bit for caramelization and balance.
• Garlic powder: Boosts the savory depth.
• Lemon wedges: For a finishing burst of brightness.

Optional additions:

• Make your own Cajun mix with paprika, cayenne, thyme, onion powder, and black pepper.
• Add smoked paprika or chili flakes for extra heat.

📆 Step-by-Step Instructions

1. Make the seasoning: Mix 1 tbsp Cajun seasoning, 1 tsp brown sugar, and ½ tsp garlic powder in a small bowl.

2. Prep the salmon: Pat the fillets dry and brush the top (flesh side) with olive oil.

3. Season generously: Press the spice mixture firmly onto the oiled flesh side.

4. Air fry: Preheat air fryer to 400°F. Place salmon skin-side down in the basket. Cook for 7–8 minutes.

5. Serve: Squeeze with fresh lemon juice and serve with avocado cream sauce if desired.

Avocado Cream Sauce:

• Mash 1 ripe avocado with ¼ cup sour cream, 1 tbsp lime juice, and a pinch of salt.

Tip: Don’t flip the salmon — you want the spice crust to stay intact!

⚠️ Common Mistakes to Avoid

• Skipping the oil: It helps create the crust and prevents sticking.
• Using too much sugar: Just a pinch enhances crust without burning.
• Crowding the basket: Cook in batches for that crispy finish.
• Flipping the salmon: It can disrupt the spice coating.
• Underseasoning: Press the spice in well for maximum flavor.

🍼 Variations & Add-Ons

• Spicy twist: Add cayenne or hot sauce to the avocado cream.
• Low-carb: Serve with cauliflower rice or a green salad.
• Comfort version: Pair with creamy mashed potatoes or mac & cheese.
• Southern-style bowl: Serve with corn salsa and black beans.
