  • Chicken broth- brings the flavors of the sauce together.
  • Seasonings- salt, pepper, and paprika are classic seasonings that are used for this dish. The minced garlic also adds great flavor to the sauce.
  • Oil and butter- use butter to fry the flounder and saute vegetables in canola or olive oil.

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: 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.
