Baked Flounder with Lemon Garlic and Butter is an easy dinner that goes from prep to table in under 30 minutes. The fish is buttery, flaky, and full of fresh citrus and garlic flavors.
Who doesn’t love an easy meal that’s big on flavor? We are big fans of quick and easy dishes that use fresh herbs, citrus, and spices to add flavor without a lot of fuss.
Baked flounder with lemon garlic and butter is one of those meals. The flounder is baked in a lemon butter sauce filled with fresh garlic, onion powder, salt, and pepper.
Then the fish is sprinkled with smoked paprika for an extra touch. Flounder is a light, white fish that flakes beautifully and pairs well with vegetables or salad for an easy dinner.
How to Make Baked Flounder with Lemon Garlic and Butter:
Start by preheating the oven, and buttering a 9 x 13-inch baking dish. Set aside. Since the fish is usually on the thinner side and it’s delicate, we bake it on a lower temperature of 325°F.
In a small bowl, whisk together the melted butter, lemon juice, garlic, onion powder, salt, and pepper. Please use freshly squeezed lemon juice and not imitation.
Pat the fish fillets dry with a paper towel, and check for any small bones. Lay the fillets in the prepared baking dish.
It’s okay to overlap the fish if it doesn’t fit in an even layer as long as all the fillets are in an even layer. Pour the lemon butter mixture over the fish.
Sprinkle the flounder with smoked paprika, and bake for 15 to 20 minutes or until the fillets flake easily with a fork. Depending on the thickness of the fish, it may need to bake it for a couple extra minutes.
Serve the baked flounder immediately with a drizzle of the lemon butter and garlic, extra lemon wedges, fresh vegetables, or a side salad.
What goes with baked flounder?
How do you bake fish without drying it out?
Make sure to cook the fish at the correct time and temperature for the variety that you’re baking. Although, most fish varieties cook at similar oven temperatures, they can vary slightly. The thickness and texture of the fish is also important. Less oily fish tend to dry out more easily than fattier fish like salmon or sea bass.
How do you know when flounder is cooked?
Baked flounder will be white and flake easily with a fork when it’s finished baking. Additionally, the internal temperature should range between 140° – 145°F on an instant read thermometer.
Can you use frozen fillets for baked flounder with lemon garlic and butter?
We used frozen fillets that had been thawed and patted dry, and don’t recommend using completely frozen fillets. Fresh fillets are the best bet if you’re able to locate them.
Do you have to use a lemon garlic and butter sauce?
No, there are a ton of ways to flavor flounder. Here’s a recipe for Spicy Garlic Soy Baked Flounder in a Foil Pouch that uses Asian-inspired flavors.
You can also use olive oil, salt, and pepper with some fresh lemon juice at the end. Anything that’s light and flavorful will work well without overpowering the fish.
