Ingredients

  • 8 small skinless, boneless flounder fillets (about 1 lb.)
  • salt and fresh ground pepper
  • 1 Tbsp vegetable oil
  • 2 Tbsp mayonnaise
  • 1 Tbsp Dijon mustard
  • 2 tsp finely chopped parsley
  • 4 lemon or lime wedges

Instructions

  1. Preheat the broiler and prepare a baking sheet lined with foil or parchment.
  2. Season the flounder fillets with salt and freshly ground pepper on both sides.
  3. Place the fillets on the prepared baking sheet.
  4. In a small bowl, mix mayonnaise, Dijon mustard, and chopped parsley.
  5. Spread the mustard mixture evenly over the fillets.
  6. Broil the fillets about 4 inches from the heat for 4 to 6 minutes, or until the fish flakes easily with a fork.
  7. Serve immediately with lemon or lime wedges.

Tips & Substitutions

For a twist, try using Greek yogurt instead of mayonnaise for a lighter version. If you don't have Dijon mustard, yellow mustard can work in a pinch, although the flavor will be slightly different. Be careful not to overcook the flounder; it should flake easily but remain moist. Fresh herbs like dill or chives can also enhance the flavor profile.

Serving Suggestions

Serve the broiled flounder with a side of steamed vegetables or a fresh salad for a light meal. It pairs beautifully with Summer Fruit Salad for a refreshing contrast. Consider offering a crusty bread to soak up any remaining mustard sauce, enhancing the overall dining experience.

Storage & Reheating

Store any leftover broiled flounder in an airtight container in the refrigerator for up to 2 days. To reheat, place the fillets on a baking sheet and warm them in a preheated oven at 350°F (175°C) for about 10 minutes, or until heated through. Avoid microwaving, as it can make the fish rubbery.

You can substitute flounder with other mild, white fish like sole, tilapia, or cod. Just keep in mind that cooking times may vary slightly depending on the thickness of the fillets, so monitor them closely while broiling.

How can I make this dish gluten-free?

This recipe is naturally gluten-free, but always check your mayonnaise and mustard brands for gluten-containing ingredients. You can also serve it with gluten-free sides like quinoa or rice to keep the meal entirely gluten-free.
