Preheat your oven to 400°F (200°C).

Melt 4 tablespoons of unsalted butter in a small pan over medium heat, then add 3 cloves of minced garlic and sauté until fragrant.

Lay the tilapia fillets in a baking dish in a single layer and pour the garlic butter mixture over them.

Squeeze lemon juice over the fillets and sprinkle with salt and freshly ground black pepper.

Bake the fillets for 12-15 minutes until they flake easily with a fork.

Garnish with freshly chopped herbs before serving.
