Step‑by‑Step Instructions for Garlic Butter Oven Baked Tilapia
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature is perfect for ensuring that the Garlic Butter Oven Baked Tilapia cooks evenly and develops a lovely, golden top. While the oven heats, you can prepare your baking dish to streamline the cooking process.
Step 2: Prepare the Baking Dish
Lightly grease a baking dish with butter or a splash of olive oil to prevent sticking. This will help your tilapia fillets cook beautifully and remain moist. A 9×13-inch baking dish works well for this recipe, allowing enough room for the fish fillets to lay flat for even cooking.
Step 3: Sauté the Garlic
In a small saucepan, melt a generous amount of butter over medium heat. Once melted, add minced garlic and sauté for about 1 minute. Look for that wonderful aroma wafting through your kitchen—this signifies the garlic is fragrant and ready for the next step. Be careful not to let it brown, as it can become bitter, affecting the dish’s flavor.
Step 4: Add Lemon Juice and Herbs
Remove the saucepan from heat and carefully stir in fresh lemon juice and your choice of chopped herbs. This mixture will create a vibrant sauce that enhances the overall flavors of the Garlic Butter Oven Baked Tilapia. The fresh ingredients should provide a lively aroma that complements the richness of the garlic butter.
Step 5: Season the Tilapia
Place the tilapia fillets in the prepared baking dish, and season them generously with salt and pepper. Make sure to spread them out in a single layer, as this ensures that each piece cooks evenly. The tilapia should be rolled or laid flat, presenting its beautiful texture to absorb all the delightful flavors from the garlic butter.
Step 6: Drizzle with Garlic Butter
Pour the garlic butter mixture evenly over the tilapia fillets, ensuring each piece is well-coated. This step is crucial for infusing the fish with that garlicky goodness, which will melt into the fish as it bakes. You’ll want to see the butter pooling slightly around the edges, allowing for maximum flavor absorption.
Step 7: Bake the Tilapia
Place the baking dish in the preheated oven and bake the Garlic Butter Oven Baked Tilapia for 15-20 minutes. The fish is done when it appears opaque and flakes easily with a fork. Keep an eye on it to ensure it doesn’t overcook; achieving a tender, flaky texture is the goal.
Step 8: Garnish and Serve
Once baked, remove the tilapia from the oven and let it cool slightly. Garnish with additional fresh herbs and lemon wedges, if desired. This adds a lovely color contrast and enhances the dish’s fresh flavor. Your Garlic Butter Oven Baked Tilapia is now ready to be served alongside your favorite sides for a delightful meal!

Garlic Butter Oven Baked Tilapia Recipe FAQs
