Ingredients Notes
Key ingredients like fresh garlic, butter, and lemon are crucial for capturing the essence of this dish. Opt for high-quality tilapia fillets from a reputable source to ensure freshness. If fresh tilapia isn’t available, consider sourcing frozen fillets as a practical alternative. The aromatic herbs enhance the buttery sauce, providing depth and complexity.
Recipe Steps
Step 1
Preheat your oven to 375°F (190°C) and lightly grease a baking dish. Ensure your tilapia fillets are thawed, if previously frozen. Pat them dry with paper towels to remove excess moisture; this helps the seasoning adhere better.
Step 2
In a small saucepan, melt the butter over medium heat. Once melted, add minced garlic and sauté until fragrant but not browned. Remove from heat and mix in freshly squeezed lemon juice.

Place the tilapia fillets in the prepared baking dish. Pour the garlic butter mixture evenly over the fillets, ensuring they’re well coated. Season lightly with salt, pepper, and a sprinkle of your chosen herbs.
Step 4
Cover the baking dish with foil and bake for about 15-20 minutes, or until the fish flakes easily with a fork. The cooking time may vary slightly based on the thickness of the fillets.
Step 5
Once cooked, remove the dish from the oven and let it rest for a few minutes. Garnish with chopped parsley and additional lemon slices for extra zest before serving.
Storage Options
Leftover tilapia can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, place the fish in a preheated oven at a low temperature to maintain its moisture. Alternatively, the dish can be frozen for up to one month. Ensure it’s completely cooled and stored properly. Thaw in the refrigerator overnight before reheating.
Variations & Substitutions
For those with dietary restrictions, substitute the butter with a dairy-free alternative or olive oil. To inject more flavor, consider adding cayenne pepper or smoked paprika. Alternatively, switch the tilapia for another white fish such as cod or haddock for a different taste experience.
