Lemon Garlic Butter Baked Fish Fillets
Lemon garlic butter baked fish is one of those simple, feel-good dinners that always feels fresh and comforting. It is light enough for a weekday meal, but still flavorful enough to feel like something special. As the fish bakes, the butter melts into the fillets, the garlic turns warm and fragrant, and the lemon adds that bright little sparkle that makes everything taste clean and lively.
This recipe is perfect for nights when you want a meal that comes together quickly without much effort. The fish turns tender and flaky, with a gently seasoned top and a buttery sauce that gathers in the bottom of the baking dish. Spoon that sauce over the fillets right before serving, and you have a beautiful, cozy seafood dinner in under 30 minutes.
It is simple, fresh, and wonderfully satisfying — the kind of recipe you can make again and again with whatever white fish you have on hand.

Ingredients
For the Fish
- 4 white fish fillets, such as cod, tilapia, haddock, or halibut
- 2 tablespoons olive oil
- 2 tablespoons unsalted butter, melted
- 3 cloves garlic, minced
- 1 tablespoon fresh lemon juice
- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon dried parsley
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon chili flakes, optional
For Garnish
- 1 lemon, cut into wedges or slices
- 2 tablespoons fresh parsley, chopped
- Extra melted butter, optional
Instructions
Preheat your oven to 400°F. Lightly grease a baking dish, or line it with parchment paper for easy cleanup.
Pat the fish fillets dry with paper towels. This helps the seasoning cling nicely. Arrange the fillets in the prepared baking dish in a single layer, giving them a little space if you can.
In a small bowl, stir together the melted butter, olive oil, minced garlic, fresh lemon juice, paprika, garlic powder, onion powder, dried parsley, salt, black pepper, and chili flakes if you want a touch of heat.
Brush the lemon garlic butter mixture generously over the fish fillets. Make sure the tops are nicely coated so every bite has that buttery, garlicky flavor.
Bake the fish for 12 to 15 minutes, depending on the thickness of the fillets. The fish is ready when it looks opaque and flakes easily with a fork.
For a little extra color on top, turn on the broiler for the last 1 to 2 minutes. Keep a close eye on it, because the butter and garlic can brown quickly.
Sprinkle the baked fish with fresh parsley. Spoon some of the buttery pan sauce over the fillets, then serve warm with lemon wedges on the side.
Presentation
For a bright, beautiful plate, place each fish fillet on a bed of rice, roasted potatoes, or steamed vegetables. Spoon a little of the lemon garlic butter sauce over the top so it glistens.
Add a lemon wedge or thin lemon slice beside each fillet for a fresh pop of color. A sprinkle of chopped parsley makes the dish look light and vibrant, while a drizzle of extra melted butter can make it feel a little more indulgent.
This fish also looks lovely served family-style in the baking dish, with lemon slices tucked around the fillets and fresh herbs scattered over the top.
