Ingredients

4 tilapia fillets (about 6 oz each)
3 tablespoons unsalted butter, melted
3 garlic cloves, minced
1 tablespoon fresh lemon juice
1 teaspoon lemon zest
1 teaspoon paprika
½ teaspoon salt
¼ teaspoon black pepper
Fresh parsley, chopped, for garnish
Lemon wedges, for serving

Instructions

Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it with butter.
Prepare the lemon garlic butter: In a small bowl, mix melted butter, minced garlic, lemon juice, lemon zest, paprika, salt, and pepper.
Place tilapia fillets on the prepared baking sheet in a single layer. Brush generously with the lemon garlic butter mixture on both sides.
Bake the tilapia for 10–12 minutes, or until the fish flakes easily with a fork. Baking time may vary depending on fillet thickness.
Optional broil: For a lightly golden finish, broil the tilapia for an additional 1–2 minutes, watching closely to prevent burning.
Garnish and serve: Sprinkle chopped parsley over the baked tilapia. Serve immediately with lemon wedges on the side.

Tips for the Best Baked Tilapia

Check for doneness: Tilapia is done when it flakes easily with a fork and is opaque throughout. Overcooking can make it dry.
Fresh fish matters: If possible, buy fresh tilapia from a reliable source; frozen fillets work too, but thaw completely first.
Customize the butter: Add a pinch of cayenne for heat or a teaspoon of honey for a subtle sweetness.
Prevent sticking: Use parchment paper or lightly oil the baking sheet to prevent the delicate fillets from sticking.

Variations to Try

Herb-Infused Tilapia: Add fresh thyme, rosemary, or dill to the lemon garlic butter for a more aromatic profile.
Spicy Tilapia: Mix ¼ teaspoon chili flakes or smoked paprika into the butter sauce.
Parmesan Tilapia: Sprinkle 2 tablespoons of grated Parmesan on top before baking for a cheesy crust.
Mediterranean Style: Add chopped olives, cherry tomatoes, and a drizzle of olive oil after baking.

Serving Suggestions

Pair this tilapia with:

Steamed vegetables (broccoli, asparagus, or green beans)
Rice pilaf or quinoa
Garlic mashed potatoes
A fresh garden salad
Crusty bread to soak up the lemon garlic butter
