HOW TO MAKE FLOUNDER RECIPE:

  • Mix seasonings:  First, combine a teaspoon of salt, paprika, and some black pepper in a small bowl
  • Prep flounder: Pat the fish dry and cut flounder filets in half, or keep them whole if you prefer. Season each filet on both sides with the prepared seasoning mixture.

  • Cook flounder: Melt butter in a large skillet and add flounder fillets. Saute for 3-4 minutes per side, depending on the thickness of the filets. Remove from pan and cover to keep warm.

Then, add tomatoes, chicken broth, garlic, and the remaining seasoning. Saute over medium heat until vegetables are tender.

Frequently asked questions-

Is flounder healthy?

Flounder is a mild, saltwater fish high in vitamin B12 and omega-3 fats. It also contains magnesium and phosphorus, which are important to include in a well-balanced diet. Plus, it is high in protein and low in calories, so it is a perfect addition to your weekly meal plan.

How do I know my fish is cooked through?

Flounder is a delicate fish that cooks quickly! Make sure not to overcook by cooking just until the inside of the fish reaches a temperature of 140-145 degrees F. When you pierce fish with a fork in the thickest spot and twist gently, it should flake easily when done.

Can I use frozen fish for this recipe?

You can use frozen flounder. Make sure to thaw completely and pat dry before cooking.

Can I bake the flounder?

Yes. Preheat the oven to 325°F. Place seasoned flounder in a baking dish and bake for 15-25 minutes, depending on the thickness of your fillets. Prepare sauce as directed and add baked flounder to the skillet and serve.

STORE & REHEAT:

  • Store: Keep leftovers in an airtight container in the fridge for 2-3 days.
  • Reheat: Place in a skillet until just warmed through or place in a microwave.
  • Freezing: We do not recommend freezing this recipe. The textures of the sauce and fish will change if frozen, so this meal is best enjoyed fresh.
