Ingredients

  • 1 teaspoon butter
  • 1 teaspoon olive oil
  • 12 cup onions or 12 cup dried shallots, thinly sliced
  • 2 cups fresh white mushrooms or 2 cups cremini mushrooms, thinly sliced
  • 1 tablespoon balsamic vinegar
  • 8 eggs
  • 13 cup fresh parsley, coarsely chopped
  • fresh ground pepper

Method

  • Preheat broiler.
  • Heat butter and oil in a nonstick 8-inch ovenproof skillet over medium heat.
  • Add onions and cook for about 2 minutes or until golden.
  • Stir in mushrooms and balsamic vinegar; cook for about 3 minutes.
  • Lightly beat eggs with parsley and pepper.
  • Pour into pan and lower heat to medium-low, stirring quickly just enough to mix mushroom mixture.
  • As mixture sets at the edges, with spatula, gently lift cooked portion to allow uncooked egg to flow underneath.
  • Cook until the bottom is set and the top is almost set, about 4 minutes.
  • Place under broiler for 2-3 minutes or until eggs are set.
  • Cut into wedges to serve.
  • TIP: For a change of taste, replace 1 cup sliced mushrooms with 1 cup cooked diced ham.
  • You can also bake the frittata in the oven.
  • Spray a 9-inch square pan with vegetable spray.
  • Pour in egg and mushroom mixture.
  • Bake at 350F for 15-20 minutes, or until set.
