Champignon Florentine (Portobello Mushrooms with Spinach-Cheese Filling)
  • 6-12 portobello mushrooms, depending on size1 or 2 per person
  • 2tablespoons olive oil or ghee
  • 1pound raw spinachabout 8 cups
  • 1cup (4 ounces) grated Gruyère, Swiss, or cheddar cheese
  • 1tablespoon freshly grated Romano cheese
  • 1/4teaspoon freshly ground black pepper
  • Dash of hot sauce (such as Tabasco), or a pinch of cayenne pepper
  • Toasted pine nutsfor garnish
  • 2 1/2tablespoons melted butter or ghee
  • 2tablespoons unbleached white flour
  • 1 1/2cups steaming hot low-fat milk
  • 1cup (4 ounces) grated Gruyère or Swiss cheese
  • Pinch of grated nutmeg
  • Pinch of ground coriander
  • Salt and pepperto taste
  1. Remove mushroom stems and gills; discard. Wipe mushroom caps with a damp cloth to clean. In a large skillet, sauté mushrooms in 2 tablespoons olive oil or ghee until barely tender and juicy. (You don’t need to cook all the way through because they will also be baked.) Transfer to a lightly oiled 10×13-inch baking dish or sheet.
  2. For the Mornay sauce, melt butter or ghee in a saucepan. Add flour and stir to make a thick paste. Rapidly whisk in steaming milk. Heat until thickened, whisking briskly and constantly to prevent lumps. Gently whisk in grated cheese and seasonings. Cover and keep warm.
  3. Wash spinach and remove tough stems. Transfer to a large saucepan; cover and steam in the water that clings to the leaves until just wilted, about 5 minutes. Place wilted spinach in a colander and spray with cold water. Squeeze out excess moisture and chop. Stir chopped spinach, grated cheeses, black pepper, and hot sauce or cayenne into hot Mornay sauce.
  4. Fill each mushroom with a generous spoonful of spinach-cheese mixture. Bake, uncovered, at 350° for 15–20 minutes or until filling is bubbling and lightly browned. Sprinkle with toasted pine nuts and serve hot.
