Ingredients You’ll Need

Mahi Mahi fillets – fresh or frozen and thawed; firm and flaky
Zesty Italian Seasoning Mix – for a punch of flavor in every bite
Mayonnaise – helps lock in moisture while adding creaminess
Parmesan cheese – adds rich, nutty flavor to the crust
Breadcrumbs – regular or panko for that golden crisp
Garlic – always essential with fish
Olive oil – for the marinade and to keep everything juicy
Lemon wedges – a must-have for serving

Tip: If you’re out of the Italian seasoning packet, try a homemade blend of dried basil, oregano, parsley, garlic powder, onion powder, salt, and a pinch of sugar.

How to Make Baked Mahi Mahi

Marinate the fish.
In a small bowl, whisk together olive oil, minced garlic, Italian seasoning, a pinch of salt, and black pepper. Brush or spoon over the fillets and let them rest for 10–15 minutes while the oven preheats.

Prepare the crust.
In another bowl, stir together mayonnaise, shredded parmesan, and a touch more seasoning if you like. Spread this mixture evenly over the top of the fillets.

Add breadcrumbs.
Sprinkle panko or regular breadcrumbs on top of the parmesan mixture, pressing lightly so it sticks.

Bake.
Place the fish in a lightly greased baking dish or on a parchment-lined sheet. Bake at 400°F for 15–20 minutes, depending on the thickness of your fillets. The fish should flake easily and reach an internal temp of 140–145°F.

Finish with lemon.
Serve hot with fresh lemon wedges. That final squeeze of citrus brings everything together.

What to Serve With Baked Mahi Mahi

This fish pairs beautifully with:

Roasted asparagus or green beans
Rice pilaf or garlicky mashed potatoes
Side salads like a berry spinach salad or crisp garden greens
Lemon herb couscous for a quick, flavorful starch

Tips for Success

Use parchment paper or lightly spray your baking dish to prevent sticking.
Frozen fillets? Thaw them completely and pat them dry before marinating.
Make it your own. Add a little paprika or lemon zest to the crust for extra flavor.
No mayo? You can swap it with plain Greek yogurt or a little sour cream.

Storage and Reheating

Leftover mahi mahi will keep well in the fridge for up to 2 days. The best way to reheat it is in the air fryer or oven — it brings that crispy crust right back to life. Avoid the microwave, which tends to make fish rubbery and the coating soggy.

Final Thoughts

This baked mahi mahi is a recipe you’ll turn to again and again. It’s unfussy, flavorful, and feels a little more elevated than your average weeknight dinner. Whether you’re serving it with spring veggies or a buttery baked potato, it’s a dish that always hits the spot.
