  • 1.1 lb mahi mahi fish fillets or 500 gm.
  • 2 tsp. extra virgin olive oil
  • 2 tbsp. Cajun spice or fajita seasoning or see Notes for other spice rub suggestions
  • ½ tsp. pepper optional
  • ¼ tsp. salt
  • 1 tbsp. lemon juice for garnish optional


  • I used a large filleted fish of about 1.1 lb and cut it into smaller fillets. Pat them dry and keep aside.
  • Assemble 2 tsp. olive oil, 2 tbsp. Cajun spice or fajita seasoning, ½ tsp. pepper (optional if you like more heat) and salt to taste. Mix well.
  • Brush the fillets with oil and apply the spice rub all over the fish. You may keep aside for 15 minutes or cook right away.
  • Preheat air fryer at 360F or 180C for 4 minutes.
  • Brush air fryer basket with oil and lay the prepared fillets so that they have ample space between them.
  • Air fry for 10-14 minutes at 360F or 180C till they are flaky and well cooked inside. You can check with a fork to be sure.
  • A trick I use is to remove the thinner or smaller fillets first as they cook faster and cook some more for thicker or larger fillets.
  • Take care not to overcook the fish or it will get rubbery.
  • Sprinkle lemon juice on top and serve hot. It is delicious. You can serve with sautéed veggies, salad and/or some rice.


1. Do not overcook. Always check with a fork. If the fish flakes easily, it is done. If not, cook for 1-2 minutes more and check again.
2. You can make the same recipe with frozen fillets too. Just make sure you cook it in the air fryer till the fish is thawed which takes about 3-4 minutes. Then apply the oil and spice rub and cook as normal.
3. You can vary the seasonings as per choice. You can also just use salt, pepper and some smoked paprika or cayenne as a rub if you want something simpler.
4. There is no need to flip the fillets during cooking.
5. Do not crowd the air fryer while cooking so that the fillets cook evenly.
6. If your fillets are unevenly sized then pay attention that the smaller, thinner fillets will get cooked quickly while the thicker, bigger ones will take longer.
7. You can use ½ tsp. onion powder, ½ tsp. garlic powder, ½ tsp. pepper, ½ tsp. cayenne or paprika, ½ tsp. Italian seasoning and salt to taste in place of Cajun spice or fajita seasoning and use.
