  • 1 Tbsp. vegetable oil

  • 1 Tbsp. Dijon mustard
  • 2 tsp. minced parsley
  • 4 lemon wedges

  2. Sprinkle the fillet halves with salt and pepper. Brush with vegetable oil.
  3. Arrange the fillets on a pan.
  4. Blend mayonnaise, Dijon mustard, and minced parsley; brush evenly over the fillets.

  6. Broil for about 1 minute or until golden brown on top and the fish is cooked through.
  7. Serve with lemon wedges.

Tips & Substitutions

For added flavor, consider marinating the flounder in lemon juice and herbs for 30 minutes before cooking. If you don't have Dijon mustard, yellow mustard can be a substitute, though the flavor will be milder. Fresh parsley can be swapped with dried, using about one-third of the amount. Keep an eye on the broiler to prevent burning, as cooking times may vary.

Serving Suggestions

Serve the broiled flounder with a side of steamed vegetables or a fresh salad for a light meal. The dish pairs well with lemon rice or quinoa for a wholesome experience. Consider serving it alongside a tangy dish like Slaw Overnight for a refreshing contrast.

Storage & Reheating

Store any leftover broiled flounder in an airtight container in the refrigerator for up to 2 days. To reheat, place the fillets in a preheated oven at 350°F for about 10 minutes or until warmed through, ensuring they don’t dry out. Avoid microwaving, as it may result in a rubbery texture.

Frequently Asked Questions

Can I use frozen flounder fillets for this recipe?

Yes, you can use frozen flounder fillets. Just ensure they are completely thawed and patted dry before cooking. This helps the seasoning adhere better and prevents excess moisture from affecting the cooking process.

What other herbs can I use instead of parsley?

You can substitute parsley with other fresh herbs like dill or chives, which will add a different yet delightful flavor to the dish. If using dried herbs, use about one-third of the quantity, as dried herbs are more potent than fresh ones.

How do I know when the fish is done cooking?

The flounder is done when it is opaque and flakes easily with a fork. Typically, broiling for about 1 to 3 minutes is sufficient, but check frequently to avoid overcooking. The internal temperature should reach 145°F for safety.
