Prep the Oven: Preheat your oven to 375°F (190°C) and prepare a baking dish by lightly greasing it with a bit of butter or oil.
Prepare the Garlic Butter: In a small saucepan, melt the butter over medium heat. Add the minced garlic and sauté for about 1-2 minutes until fragrant, but not browned. Remove from heat and add the lemon juice, zest, and season with salt, pepper, paprika, and red pepper flakes if using.
Season the Fish: Pat the tilapia fillets dry with paper towels and season both sides with salt and pepper. Place them in the greased baking dish.
Add the Garlic Butter: Pour the garlic butter mixture evenly over the tilapia fillets, making sure they are well coated.
Bake the Fillets: Bake the tilapia in the preheated oven for 15-20 minutes, or until the fish flakes easily with a fork and is opaque.
Garnish and Serve: Once done, remove from the oven and sprinkle with freshly chopped parsley. Serve warm with lemon slices on the side for an extra zing.
Notes
Serve the garlic butter tilapia on a bed of steamed rice or alongside roasted vegetables. Garnish the plate with a sprinkle of parsley and a lemon wedge for a pop of color.
