The classic combination of lemon pepper, butter, and garlic is versatile—equally at home on chicken, vegetables, or this mild white fish. The method is straightforward: layer the fillets, drizzle with lemon and butter, sprinkle spices, and bake. It’s forgiving, fast, and adaptable to what you have on hand.

If you find fillets in the freezer, this is one of the fastest dinners you can make. Tilapia thaws quickly and the flavors here help brighten any mild fish.

  • Flexible — works with many types of mild white fish and adapts to different seasonings.

Ingredients

  • 16 ounces tilapia fillets (or other mild white fish) — about 4 fillets
  • 8 teaspoons butter (salted or unsalted)
  • 4 tablespoons lemon juice
  • 1/4 teaspoon lemon-pepper seasoning
  • 1/2 teaspoon garlic powder
  • 1/8 teaspoon sweet paprika
  • Sea salt to taste

  1. Preheat the oven to 425°F (220°C).
  2. Pat the fillets dry with paper towels and arrange them in a baking dish coated with cooking spray.
  3. Pour the lemon juice over the fillets and dot with small pats of butter. You can melt the butter first for a more even coating, or leave it in pats so it melts while baking.
  4. Sprinkle lemon-pepper seasoning, garlic powder, paprika, and a pinch of salt evenly over the fish. Use your fingertips to distribute spices more evenly if needed.
  5. Bake uncovered for 10–12 minutes, or until the fish flakes easily with a fork and reaches an internal temperature of 145°F (63°C). Cooking time will vary with thickness—thicker fillets may need a minute or two more.
  6. Garnish with green onions, chopped parsley, and lemon slices if desired. Serve immediately.

For extra lemon flavor, grate a little lemon zest over the fillets just before serving.

Should you rinse tilapia before cooking it?

There’s no need to rinse store-bought packaged tilapia. Rinsing can spread bacteria in the kitchen. Simply pat the fillets dry with paper towels to remove excess moisture before seasoning and baking. Properly stored tilapia should not have a strong fishy odor; the lemon in this recipe helps brighten and neutralize any mild aroma.

Storage

Store leftover tilapia in an airtight container in the refrigerator for 3–4 days. For longer storage, freeze cooked fillets for up to 2 months; thaw in the refrigerator before reheating gently.
