Preheat the oven to 400°F, placing the oven rack in the upper middle position. Line a 13x9-inch baking dish with parchment and set aside.
Pat dry the tilapia fillets with paper towel and place in the prepare pan.
In a small bowl, whisk together the melted butter, lemon juice, garlic, salt, pepper and optional herbs.
Brush the tilapia evenly with the butter mixture until fully coated.
Bake uncovered for about 10 minutes. After 8 minutes, check the internal temp of tilapia by inserting an instant-read thermometer into the thickest part of the fish. You can remove it from oven with a reading of 140°F (60°C) for a final temp of 145°F upon serving.
