How to Make Garlic Butter Oven Baked Tilapia

Place the tilapia fillets on top of the lemon slices. Ensure they are arranged evenly for a consistent cooking texture.
Pour the prepared garlic butter mixture over the fillets. Make sure to coat them well, as this will keep the fish moist and flavorful while baking.
