How to Make Lemon Herb Baked Tilapia

Preheat your oven to 400°F (204°C) and lightly grease a large baking dish or line it with parchment paper for easy cleanup.
In a small bowl, whisk together the olive oil, minced garlic, lemon zest, lemon juice, oregano, thyme, parsley, smoked paprika, salt, and pepper until well combined. This herb marinade is the flavor backbone of the entire dish.
Pat the tilapia fillets thoroughly dry with paper towels — this step is critical for getting a slightly golden exterior rather than steaming the fish in its own moisture.
Arrange the fillets in a single layer in your prepared baking dish, making sure they don’t overlap. Pour the lemon herb mixture evenly over each fillet, using a spoon or brush to coat the tops completely.
Lay two or three thin lemon slices on top of each fillet. This keeps the fish moist during baking and infuses additional citrus flavor as it heats through.
Bake uncovered for 13 to 15 minutes, until the fish is opaque throughout and flakes easily when pressed with a fork at its thickest point. Tilapia is thin, so check at the 12-minute mark to avoid overcooking — overcooked tilapia becomes rubbery and loses its appeal.
Remove from the oven, scatter fresh parsley over the top, and serve immediately with your choice of sides. A spoonful of the pan juices drizzled back over the fish adds even more flavor.
