Ingredients

  • 6 fillets of flounder or sole
  • 1 large red sweet onion
  • 1 lemon
  • salt
  • pepper
  • butter
  • water

Instructions

  1. Fill a large skillet with enough water to just cover the bottom.
  2. Place the flounder fillets in the skillet.
  3. Slice the red sweet onion into very thin rings and arrange them on top of the fish in the skillet.
  4. Cut the lemon in half and squeeze the juice evenly over the fish and onion.
  5. Slice the butter and place the slices around the top of the fish and onion.

Tips & Substitutions

For enhanced flavor, consider adding fresh herbs like dill or parsley atop the flounder before cooking. If you don't have flounder, sole is a great substitute. Ensure the water doesn’t boil; a gentle simmer will keep the fish tender. Adjust the amount of butter to your taste, or use olive oil for a lighter option.

Serving Suggestions

Serve the stewed flounder with a side of steamed vegetables or a light salad for a refreshing meal. It pairs beautifully with Shrimp Dip 'N Bread as an appetizer. For a heartier option, consider a side of rice or quinoa to soak up the flavorful juices.

Storage & Reheating

Store any leftover stewed flounder in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm in a skillet over low heat with a splash of water to maintain moisture. Avoid microwaving as it can make the fish rubbery.

Frequently Asked Questions

Can I use frozen flounder for this recipe?

Yes, you can use frozen flounder. Just ensure to thaw it completely in the refrigerator before cooking. This will help achieve even cooking and the best texture.

What can I substitute for red sweet onion?

If you don’t have red sweet onion, yellow onion or shallots can work as substitutes. They will provide a slightly different flavor but will still complement the dish nicely.

How do I know when the flounder is done cooking?

The flounder is done when it turns opaque and flakes easily with a fork, typically after about 5-7 minutes of gentle simmering. Avoid overcooking to keep it moist and tender.
