Step‑by‑Step Instructions for Baked Tilapia
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This essential step ensures that your Baked Tilapia cooks evenly and achieves a delightful golden hue. While the oven heats up, gather your ingredients and prepare your baking dish for a smooth cooking experience.
Step 2: Season the Tilapia
Next, season both sides of the tilapia fillets generously with kosher salt and freshly ground black pepper. This will enhance their natural flavor and prepare them for the rich garlic lemon butter. Once seasoned, place the fillets in a lightly greased baking dish, arranging them in a single layer for even cooking.
Step 3: Prepare the Garlic Lemon Butter
In a small bowl, melt 5 tablespoons of unsalted butter in the microwave or on the stove until fully liquid. Add the finely chopped garlic, crushed red pepper flakes, lemon juice, and zest. Stir everything together until it’s well combined, creating a fragrant mixture that will elevate the taste of your Baked Tilapia.
Step 4: Pour the Butter Mixture
Carefully pour the garlic lemon butter mixture over the seasoned tilapia fillets, making sure to coat them evenly. Then, lay fresh lemon slices on top of each fillet for an extra burst of citrus flavor. This layering will not only enhance the aroma but also infuse the fish with a delightful zesty note.
Step 5: Bake the Tilapia
Place the baking dish in the preheated oven and bake for about 10 to 20 minutes. Keep a close eye on your tilapia; it is ready when its internal temperature reaches 145°F (63°C) and the fish appears opaque and flaky. The fragrant aroma filling your kitchen will signal that you’re nearly there!
Step 6: Serve and Garnish
Once baked to perfection, carefully remove the tilapia from the oven. Use a spatula to transfer the fillets to plates, drizzling any remaining garlic lemon butter from the dish over the top. Finish by garnishing with chopped fresh parsley for a colorful and flavorful touch, making your Baked Tilapia not only delicious but visually appealing!
