Ingredients (Serves 4)

  • 4 flounder fillets (about 6 ounces each)
  • 3 tablespoons melted butter
  • 3 cloves garlic, minced
  • 1 cup grated Parmesan cheese
  • 1 teaspoon paprika
  • Salt and pepper, to taste
  • Fresh parsley, chopped (for garnish)
  • Lemon wedges, for serving

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). This ensures the Parmesan topping will crisp up beautifully while keeping the fish juicy and tender.

Step 2: Prepare the Baking Dish

Lightly grease a baking dish with cooking spray or a small amount of butter. This will prevent the flounder from sticking and make cleanup easier.

Step 3: Mix the Garlic Butter Sauce

In a bowl, stir together the melted butter and minced garlic until well blended. Then add half of the grated Parmesan cheese, the paprika, and a pinch of salt and pepper. Mix until combined — this will become your flavorful, rich topping.

Step 4: Coat the Flounder

Arrange the flounder fillets in the prepared baking dish. Spoon the garlic butter mixture evenly over the top of each fillet, ensuring the fish is well coated for maximum flavor.

Step 5: Add More Parmesan

Sprinkle the remaining Parmesan cheese generously over the coated fillets. The cheese will melt and form a deliciously crispy, savory crust while baking.

Step 6: Bake

Transfer the baking dish to the oven and bake for 12–15 minutes, or until the flounder easily flakes apart with a fork and the top is golden brown.

Step 7: Garnish and Serve

Once baked, remove from the oven and sprinkle with chopped fresh parsley for a burst of color and freshness. Serve each portion with lemon wedges on the side — the bright acidity of lemon is the perfect contrast to the rich, cheesy topping.

Enjoy this dish hot, fresh from the oven, for the best flavor and texture!

Why This Recipe Works

Flounder is a mild, delicate white fish that pairs beautifully with bold flavors. The combination of melted butter, garlic, and Parmesan enhances the flounder without overpowering it, while paprika adds a subtle smoky warmth.

Because flounder fillets are thin, they cook quickly, making this an ideal weeknight dinner. The quick oven bake locks in moisture while the Parmesan topping crisps to perfection.

Tips for Success

  • Use fresh flounder if possible: It has the best flavor and texture
  • Pat fish dry: This helps the topping adhere and prevents watery results
  • Don’t overbake: Flounder cooks fast; check after 12 minutes
  • Customize the flavor: Add a sprinkle of crushed red pepper for heat, or swap paprika for smoked paprika
  • Serve immediately: This dish is best enjoyed hot, straight from the oven

Storage & Reheating

Storage: Store leftover garlic Parmesan flounder in an airtight container in the fridge for up to 2 days.

Reheating: Reheat gently in a 300°F oven for about 5–7 minutes, or until just warmed through. Avoid the microwave, which can make fish rubbery.

Variations

  • Lemon zest: Stir a teaspoon of lemon zest into the butter for extra brightness
  • Fresh herbs: Add chopped basil, thyme, or dill to the garlic butter
  • Breadcrumbs: Mix in 1/4 cup of panko breadcrumbs for extra crunch
  • Low-carb: This recipe is naturally low-carb and keto-friendly
  • Different fish: Swap flounder for sole, tilapia, or cod if needed

Serving Suggestions

  • With a side of roasted asparagus or green beans
  • Over a bed of creamy mashed potatoes
  • With a crisp garden salad and a light vinaigrette
  • Paired with crusty bread for mopping up extra garlic butter
  • Alongside lemon butter pasta for a truly luxurious seafood dinner

Perfect for These Occasions

  • Quick weeknight dinners
  • Holiday seafood feasts
  • Dinner parties with friends
  • Romantic date nights
