This delicate fish is a surprising treat at the end of a long day. Turbot is found in salt waters of both the Atlantic and Pacific oceans. It is also known as flounder, brill, fluke, and plaice. It is a member of the flatfish family, which also contains halibut. Any of those would make fine substitutions in this dish.

  • almond flour or all-purpose flour
    1/2 cup
  • salt
    1/4 tsp
  • black pepper
    1/4 tsp
  • crushed red pepper flakes
    1 pinch
  • turbot or other white fish
    4 (5 oz) fillets
  • olive oil (divided)
    4 tbsp
  • frozen yellow squash and zucchini (thawed and drained)
    2 lbs
  • lemon (juiced)
  • water
    1 cup
  • fresh thyme
    2 sprig
  • balsamic vinegar
    1 tbsp
  • watercress (washed thoroughly and trimmed)
    1 bunch


  1. Place the flour on a plate. Add the salt, black pepper, and red pepper, and stir to combine. Dip the turbot fillets in the mixture to coat. Shake off the excess. Transfer to a plate and set aside.

  2. Heat 2 Tbsp of the olive oil in a large, wide, nonstick skillet over medium heat. Add the fish and brown on both sides (about 2 minutes per side).

  3. Add the squash and zucchini, lemon juice, and water. Add the thyme, cover, and allow to simmer for 5 to 10 minutes, or until the fish is cooked through and the squash is tender. Remove and discard the thyme.

  4. In a small bowl, whisk the balsamic vinegar with the remaining 2 Tbsp of olive oil until incorporated.

  5. Toss the watercress with the dressing, taste, and season with salt and pepper as needed. Place the watercress on the bottom of a large serving platter or divide among 4 individual plates.

  6. Place the fish fillets on top of the watercress and scatter zucchini and squash around the sides.
