Crispy and Juicy Frozen Mahi Mahi in the Air Fryer – Quick Seafood Perfection
If you’re craving something light, flaky, and full of flavor, frozen mahi mahi in the air fryer might just be your new favorite dinner hack.
It’s super convenient—no need to thaw—and comes out beautifully cooked: golden on the outside and moist on the inside.
I suggest preheating your air fryer to 390°F (200°C) and cooking the frozen mahi mahi fillets for 10–14 minutes, depending on thickness.
Flip them once halfway through for even browning. A touch of lemon, seasoning, and a quick spray of oil will help you get that golden, restaurant-style result.

How to Make Frozen Mahi Mahi in Air Fryer
Ready to turn those frozen fillets into a delicious dinner? Here’s how to do it with ease and confidence.
Step 1: Preheat the Air Fryer
Set your air fryer to 390°F (200°C) and let it preheat for 3–5 minutes. This helps start the cooking process immediately.
Step 2: Lightly Oil and Season
Remove the frozen fillets from the packaging. Spray lightly with oil on both sides and season with salt, pepper, garlic powder, or your favorite spice mix.
Step 3: Arrange in Basket
Place the fillets in a single layer in the air fryer basket. Leave space between pieces so air can circulate. Avoid stacking.
Step 4: Air Fry and Flip
Cook for 12–14 minutes. Flip the fillets at the halfway mark to ensure even browning. Use tongs gently to avoid breaking the fish.
Step 5: Check for Doneness
The mahi mahi should be golden on the edges and opaque in the center. Internal temperature should reach 145°F.
Rest for 2 minutes before serving.
