Crispy Oven-Baked Lemon Pepper Tilapia

This baked lemon pepper tilapia is low-carb, gluten-free, and ready in about 15 minutes—an ideal choice for a fast, healthy weeknight dinner.

The bright combination of lemon pepper, butter, and garlic brings a fresh, savory flavor to mild white fish. This simple seasoning works well on its own or as a base for fish tacos, salads, or a main course served with quick sides.

What makes this recipe so useful is how easy it is: layer the fillets, add a few seasonings and pats of butter, then bake. It’s forgiving, adaptable to other flaky white fish, and quick to prepare whether the fillets are fresh or just thawed.

Why you’ll love this baked lemon pepper tilapia:

• Fast and simple—ready in about 15 minutes from start to finish.
• Light texture and mild flavor make it family-friendly and versatile.
• Works with most flaky white fish and still performs well if the fillets are only partially thawed.

Ingredients

Keep a few pantry staples on hand and you can make this lemon pepper tilapia anytime.

• Tilapia fillets (about 16 ounces, roughly 4 fillets) — any mild white fish works: cod, haddock, halibut, basa, or similar.
• Butter — about 8 teaspoons, salted or unsalted. You can also drizzle olive oil instead.
• Lemon juice — 4 tablespoons, fresh or bottled.
• Lemon pepper seasoning — about 1/4 teaspoon; pick one without added sugar for best results.
• Garlic powder — 1/2 teaspoon. Fresh garlic can be used, but powdered garlic gives even coverage.
• Sweet paprika — 1/8 teaspoon for color and a gentle flavor note (or use smoked paprika for a different profile).
• Sea salt to taste.
• Green onions — 1/4 cup sliced, optional for color and brightness.
• Parsley — 2 tablespoons chopped, optional garnish.
• Lemon slices — optional, for serving.

If you like heat, add a pinch of cayenne pepper.

The instructions below include ingredient amounts, cook times, and simple tips.

Directions with Pictures

This is a technique-driven, forgiving recipe. Measure the first time, then adjust seasonings by eye on future preparations.

1. Preheat the oven to 425°F (220°C).
2. Pat the fish fillets dry with paper towels and place them in a lightly greased baking dish.
3. Pour 4 tablespoons lemon juice over the fillets and add small pats of butter across the top of the fish. If you prefer, melt the butter first for a more even coating; otherwise the pats will melt as the fish bakes.
4. Sprinkle lemon pepper seasoning, garlic powder, sweet paprika, and sea salt evenly over the fillets. Use your fingertips to distribute the spices for better coverage.
5. Bake the fillets, uncovered, for about 10–12 minutes, or until the fish easily flakes with a fork and reaches an internal temperature of 145°F (63°C). Cooking time depends on fillet thickness, so check for flakiness as your guide.
6. Garnish with sliced green onions, chopped parsley, and lemon slices before serving.

For extra lemon brightness, grate a little lemon zest over the fish just before serving.

Storage

Store leftover lemon pepper tilapia in an airtight container in the refrigerator for 3–4 days. For longer storage, freeze portions in a sealed container for up to 2 months. Reheat gently to avoid drying the fish.

What to Serve with Lemon Pepper Tilapia

Quick side ideas that take 15 minutes or less:

• Zucchini noodles sautéed with garlic and a little olive oil.
• Cauliflower rice, quickly cooked on the stove or roasted while the fish bakes.
• Couscous or quick-cooking grains.
• Wilted spinach tossed with lemon and olive oil.
• Roasted or steamed asparagus.
• Fresh salad or marinated tomatoes.
• Microwaved corn on the cob (in the husk for a few minutes).
• Pineapple salsa or other fresh salsas for serving on tacos.

Tip: Many of these sides can be seasoned with the same lemon, garlic, and herbs used for the fish to create a cohesive meal.

If you have more time, consider serving the fish with vegetable rice pilaf, risotto, or creamy mashed potatoes.
