  • ¾ pound spinach fresh & washed. Alternately you may use baby turnip greens
  • 2 pounds mushrooms small and cleaned
  • 1 cup butter divided
  • 2 medium onions chopped
  • 3 cloves garlic chopped
  • ½ cup breadcrumbs or panko
  • ½ teaspoon Dijon mustard
  • Salt
  • black pepper Freshly ground
  • ½ cup grated Parmesan cheese


  • Preheat oven to 350 degrees.
  • Remove and discard any stems and tough leaves from the greens. Chop the leaves in a food processor. If greens are large, blanch briefly and drain well.
  • Remove and chop the stems of the mushrooms and set aside.
  • Melt 1 ⁄ 2 cup butter in a Dutch oven or deep skillet over medium heat, and dip the mushroom caps into it until well coated on all sides. Place them top side down on a greased rimmed baking sheet.
  • Heat remaining butter in the skillet; add the onions, garlic, and chopped mushroom stems, and sauté until very soft, about 10 minutes.
  • Add the greens and cook a few minutes until wilted; drain off and reserve some of the liquid.
  • Add the breadcrumbs and mustard, and mix well. Add back some of the reserved liquid if the mixture is so dry that it doesn’t stick together easily.
  • Season to taste with salt and pepper.
  • This filling can be made several days in advance or frozen and defrosted before stuffing mushrooms.
  • Fill each buttered mushroom cap (up to 1 day in advance) with this mixture, mounding it high, and sprinkle with Parmesan cheese. Bake 10 to 15 minutes.


  1. Variation: Add 1 ⁄ 2 cup finely chopped ham, crisp bacon, sautéed sausage, chopped shrimp, crabmeat, or smoked turkey.
  2. Garnish with chopped herbs or small whole shrimp
