  • 1 tablespoon olive oil

  • 1 tablespoon butter

  • ¼ cup clamshell mushrooms, or more to taste

  • salt and freshly ground black pepper to taste

  • 2 (7 ounce) halibut fillets

  • 1 pinch cayenne pepper, or to taste

  • ¼ cup water

  • ½ lemon, juiced

  • 1 ½ tablespoons butter, room temperature but not soft

  • 1 tablespoon chopped flat-leaf Italian parsley


  1. Heat oil and 1 tablespoon butter in a heavy skillet over medium-high heat until butter melts and begins to foam. Add mushrooms and a pinch of salt; sauté in hot butter and oil until golden brown, about 5 minutes. Push mushrooms to the edges to clear a space in the center of the skillet.

  2. Season halibut on each side with salt and cayenne pepper. Place halibut fillets in the center of the skillet and cook until fillets begin to flake, 3 to 4 minutes per side. Transfer halibut to a warm serving plate.

  3. Pour water into the pan and bring to a boil while scraping the browned bits of food off of the bottom of the pan with a wooden spoon, until water is reduced by half, 1 to 2 minutes. Pour lemon juice into mushroom mixture and stir.

  4. Stir butter and parsley into mushroom mixture. Stir constantly until butter melts and forms a sauce; remove from heat and season with salt and black pepper. Spoon sauce and mushrooms over halibut.
