Step‑by‑Step Instructions for Lemon Butter Baked Mahi Mahi
Step 1: Preheat Oven
Begin by preheating your oven to 400°F (204°C). Line a baking sheet with aluminum foil or parchment paper to catch any drips and make cleanup a breeze. This initial step is crucial for achieving that perfectly flaky texture in your Lemon Butter Baked Mahi Mahi, ensuring the fish cooks evenly.
Step 2: Prepare Citrus Base
While the oven heats, take fresh lemons and slice them into thin rounds. Lay the lemon slices neatly on the prepared baking sheet, creating a flavorful bed for your mahi mahi fillets. This not only adds a delightful citrus flavor but also elevates the presentation of the dish as it bakes.
Step 3: Arrange Mahi Mahi
Now, place your mahi mahi fillets directly on top of the lemon slices. Using a brush, coat both sides of the fillets generously with melted butter, ensuring they remain moist during the baking process. This step is key in enhancing the flavor and preparing your Lemon Butter Baked Mahi Mahi for seasoning.
Step 4: Season Fish
In a small bowl, combine paprika, garlic powder, dried oregano, sea salt, dried thyme, red pepper flakes, onion powder, and ground black pepper to create a seasoning blend. Sprinkle this mixture evenly over both sides of the mahi mahi fillets, making sure each bite is packed with flavor.
Step 5: Bake
Slide the baking sheet into the oven and bake the mahi mahi for 10 minutes. After this initial cooking time, switch to the broiler setting for an additional 1.5 minutes to achieve a beautifully golden top. Keep an eye on the fish to prevent overcooking, ensuring it remains flaky and tender.
Step 6: Garnish and Serve
Once cooked, remove the Lemon Butter Baked Mahi Mahi from the oven and sprinkle with freshly chopped parsley for a vibrant touch. Serve immediately, allowing everyone at the table to indulge in the delightful flavors, with the fragrant lemon and buttery sauce stealing the show.
