Step‑by‑Step Instructions for Baked Mahi Mahi Recipe
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While the oven heats up, line a rimmed baking sheet with aluminum foil or parchment paper for easy cleanup. This will also help the fish cook evenly. Making sure your baking sheet is ready will streamline the process as you prepare your delicious Baked Mahi Mahi.
Step 2: Arrange the Lemon Slices
Once your baking sheet is ready, arrange the thin lemon slices on it in a single layer. These slices not only add moisture but also infuse the mahi mahi with a wonderful citrus flavor. The bright yellow color will make your dish visually appealing while serving as a bed for the fish as it bakes.
Step 3: Place Mahi Mahi on Lemon
Next, take your fresh mahi mahi fillets and place them gently on top of the arranged lemon slices. Carefully coat both sides of each fillet with the melted butter, ensuring they are well covered. This step enhances the flavor and promotes browning while the fish bakes, resulting in that flaky texture we love in a good Baked Mahi Mahi.
Step 4: Season the Fish
In a small bowl, combine the paprika, garlic powder, dried oregano, sea salt, thyme, onion powder, black pepper, and red pepper flakes if you like a little heat. Sprinkle this seasoning blend evenly over your mahi mahi fillets. This will elevate the fish’s natural flavor, making your meal truly tantalizing.
Step 5: Bake the Mahi Mahi
Place the baking sheet in the preheated oven and bake the mahi mahi for about 10 minutes. Your fish is done when it is opaque and flakes easily with a fork. This quick baking time keeps the mahi mahi moist and full of flavor, fitting perfectly into your Baked Mahi Mahi Recipe.
Step 6: Broil for Finishing Touch
After baking, switch your oven to broil on high for an additional 1.5 minutes. Keep a close eye on the fish during this time; you want to achieve a light, golden-brown crust on top. This final step adds a beautiful finish to your dish and ensures a deliciously crisp texture on the surface.
Step 7: Garnish and Serve
Once broiling is complete, remove the baking sheet from the oven. Sprinkle the chopped parsley over the top of the mahi mahi for a burst of color and freshness. Serve immediately while hot, and relish the delightful combination of flavors in your freshly made Baked Mahi Mahi Recipe.

How to Store and Freeze Baked Mahi Mahi
Fridge: Store leftovers in an airtight container for up to 3 days to keep the fish fresh. Reheat in the microwave, covered with a paper towel, to retain moisture.
Freezer: If you have extra baked mahi mahi, freeze it in a freezer-safe container for up to 3 months. Wrap each portion to prevent freezer burn, ensuring delicious meals later.
Reheating: When reheating from frozen, defrost in the fridge overnight first. Then, warm in the oven at 350°F (175°C) for 10-15 minutes or until heated through. A splash of lemon juice can brighten the flavors in your reheated dish.
