If you’re craving restaurant-worthy fish with a bold, smoky crust, this Air Fryer Blackened Cod is about to become your new favorite weeknight dinner. Thick cod fillets get coated in a fiery blackened spice rub, then air fried at 400°F until the outside is dark and crispy while the inside stays perfectly flaky and moist. Best of all, it’s on the table in about 20 minutes — served with a creamy lemon-dill dipping sauce that makes every bite irresistible.
Ingredients
- 2 to 4 thick-cut cod fillets (loins work best; thicker is better for the air fryer)
- 2 tablespoons olive oil or avocado oil (melted butter also works for extra richness)
- 1 tablespoon smoked paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried oregano
- 1/2 teaspoon cayenne pepper (adjust for heat)
- 1 teaspoon salt
- 1/2 teaspoon cracked black pepper
Creamy Lemon-Dill Sauce
- 1/3 cup mayonnaise
- 1 tablespoon Dijon mustard
- 1 tablespoon fresh dill, chopped (plus extra for garnish)
- 1 tablespoon minced capers or pickles
- 1 tablespoon fresh lemon juice
- 1 pinch of lemon zest
- Fresh parsley and extra lemon zest, for garnish
Instructions
- Prep the fish: Pat the cod fillets extremely dry with paper towels. This is the secret to getting that dark, crispy crust rather than “steamed” fish.
- Coat: Brush each fillet generously with oil or melted butter on all sides.
- Season heavily: Mix the spices together and press the rub firmly into the fish. You want a thick layer to create that beautiful blackened crust.
- Preheat: Heat your air fryer to 400°F (200°C).
- Air fry: Place the fillets in the air fryer basket, making sure they aren’t touching. Cook for 8 to 11 minutes, depending on thickness. Cod is done when it reaches an internal temperature of 145°F and flakes easily with a fork.
- Make the dip: While the fish cooks, whisk the sauce ingredients together. Top with a little extra fresh parsley and lemon zest for a gourmet look.
- Serve: Plate the cod with the creamy dill sauce and lemon wedges. Enjoy!
Tips for success: Don’t flip — cod is very fragile, and the circulating hot air will cook the bottom sufficiently. Start checking at the 8-minute mark, since cod can go from perfectly flaky to rubbery in about 60 seconds.
This blackened cod pairs beautifully with roasted vegetables, a crisp salad, or fluffy rice — a simple, healthy dinner that tastes like a treat. Give it a try and let me know how it turned out!
