Ingredients

  • 1/2 cup chopped onion
  • 2 tablespoons olive oil
  • 1/2 cup white wine
  • 3 cups chopped, skinned, and seeded tomatoes
  • Juice of 1/2 lemon
  • Salt and pepper to taste
  • 1 clove garlic minced
  • 2 teaspoons dried basil
  • Pinch of marjoram

Instructions

  1. Cook the chopped onion and minced garlic in olive oil over medium heat until soft.
  2. Add white wine, dried basil, and a pinch of marjoram; simmer until most of the liquid evaporates.
  3. Add chopped, skinned, and seeded tomatoes; simmer for 3 minutes.
  4. Place the flounder fillets into the simmering sauce, cover, and cook gently for 2 minutes until the fish is just firm.
  5. Remove the fish from the sauce, then add lemon juice, salt, and pepper to the sauce.
  6. Pour the sauce over the fish and serve.

Tips & Substitutions

For a richer flavor, consider adding a splash of homemade vegetable stock to the sauce alongside the wine. If you don't have fresh tomatoes, canned tomatoes can work in a pinch, just drain them beforehand. Adjust the herbs to your taste; fresh basil can replace dried for a more vibrant flavor. Pair this dish with a side of Gazpacho Salad for a refreshing complement.

Serving Suggestions

Serve the flounder poached in fresh tomato sauce with a sprinkle of fresh basil on top. This dish pairs wonderfully with a side of lentils with spinach for a wholesome meal. A light salad, such as Mushroom Cress Salad, can also provide a refreshing contrast to the richness of the sauce.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm the flounder in the sauce over low heat on the stovetop, being careful not to overcook the fish as it can become tough.
