    What is the best way to cook Mahi Mahi? In the air fryer, of course. Preparing a restaurant quality Mahi dish with only 3 ingredients in 15 minutes may seem too good to be true, but this recipe is here to prove it.

    With fresh, wholesome ingredients and an air fryer, you'll bring out the best of Mahi Mahi - a delicate and delicious fish!

    Is Mahi Mahi good eating?

    Before diving into the recipe, here are just a few of the reasons Mahi Mahi is indeed good eating:

    Sustainable: Mahi Mahi is typically commercially fished in abundance off the coast of Hawaii, Costa Rica, the Indian Ocean, and the Gulf of Mexico. That said, the Mahi Mahi population is of very little concern when it comes to over harvesting and is a responsible fish option.

    Lean & clean: Mahi Mahi is a great extra lean and low-calorie protein source. Not to mention, it's inherently gluten free, low carb, and keto friendly.

    Fresh & flavorful: One bite of this mild fish, and you'll understand the hype. The flesh has a distinctive rich, buttery, and subtly sweet flavor.

    Why You'll Love This Recipe

    • It's a healthy fish fry! There's no breading and very little oil.
    • It's quick. If you’re looking for an easy weeknight dinner option using fresh ingredients, this is it.
    • Customizable - you can season your fish with cajun spices or any seasonings you like.
    • The serving possibilities are endless.

    Ingredients You'll Need

    Labeled ingredients for the Mahi Mahi.
    • Mahi Mahi: You can cook most white fish from fresh or frozen in the air fryer, but I recommend thawing first. If you can source fresh, never frozen Mahi, even better!
    • Cajun Seasoning: A blend of salty, spicy, and smokey spices that pair perfectly with mild-tasting white fish.
    • Olive Oil: Coating the fish in oil will help achieve lightly crisped surfaces and juicy, tender centers. You can also use avocado oil or melted butter/ghee.
    • Lemon Juice: A squeeze of fresh lemon is optional but certainly recommended to enhance the flavors. Lime juice works too.

    Step-By-Step Instructions

    Steps to make the mahi mahi.

    Step 1: Prep fish. Coat both sides of the Mahi with olive oil and then rub both sides with the Cajun seasoning.

    Step 2: Cook in the air fryer. Spray the air fryer basket with nonstick cooking spray and place the fish in a single layer in the basket, leaving space between each piece. Cook for 10 to 12 minutes at 350 ℉.

    Step 3: Serve. Finish with a squeeze of fresh lemon juice and serve hot. Enjoy!

    Expert Tips

    • Pat your fish filets dry with a paper towel before coating them in oil.
    • Don't forget to spray your air fryer basket with cooking spray to keep the fish from sticking to the bottom of the basket.
    • The ideal temperature for a firm yet tender piece of Mahi is 137-145 ℉. You can use a meat thermometer or eyeball it. The flesh should flake effortlessly when pierced with a fork and be no longer be opaque.
    • Begin checking for doneness around 10 minutes. Overcooked Mahi Mahi can be very dry and chewy.
    • Mahi Mahi is best served immediately, so have the rest of the meal ready to go when the fish is finished.

    Variations

    Seasonings: Switch things up with different blends like fajita seasoning, taco seasoning, Old Bay, and garlic & herb. Spices like paprika, cayenne, cumin, oregano, chili pepper, and red pepper go great with Mahi Mahi.

    Using a different fish: You can follow this recipe using any white fish (cod, halibut, or tilapia are good options). You may need to adjust the cooking time depending on the size and thickness of your fish.

    Serving

    Seasoned and air fried Mahi Mahi goes with just about everything and can be served in a variety of different ways. Here are a few of my favorites:

    • Fish tacos: Serve flaked pieces of Mahi in corn or flour tortillas with lettuce, tomato, onion, blender salsa with fresh tomatoes, etc.
    • Cajun fish sandwich: Serve in a toasted hoagie roll with lettuce, tomato, and tartar sauce.
    • Serve with healthy sides: Prepare a couple of nutritious dishes to serve on the side like a simple green salad, keto mashed cauliflower, roasted vegetables, roasted potatoes, and mashed potatoes.

    Storing & Freezing

    Storing: Keep your cooked and cooled Mahi Mahi in an airtight container in the refrigerator for up to 3 days.

    Freezing: Wrap the fish tightly in plastic wrap and place in a freezer-safe bag or container. Store in the freezer for up to two months. Thaw in the refrigerator before reheating.

    Recipe FAQ‘s

    How long does it take to cook frozen Mahi Mahi in an air fryer?

    Frozen Mahi Mahi takes about 12 minutes to cook in the air fryer between 375 and 400 ℉. Coat the frozen fish in olive oil for the best results, cook for 5 to 6 minutes, and then coat in seasoning. Cook for 6 to 7 more minutes.

    What is the best way to thaw frozen fish?

    The most efficient way to defrost fish is by submerging the frozen fish in a bowl of cool water and leaving it be for about 20 minutes. Do not use warm or hot water because it will start cooking the fish.

    How do I reheat Mahi Mahi in the air fryer?

    Reheating fish in the air fryer is a good way to warm it without drying it out. To reheat, preheat your air fryer to 375 ℉ and cook until heated through (3 to 4 minutes).

      Sounds delicious. Is it necessary to flip the Mahi halfway through the cook time?

        Hi Cynthia, I like to flip to make sure the fish is evenly cooked on both sides, but I think it would be ok as well if you didn't flip.
