  • knife


  • 6 tablespoons butter divided
  • 1 yellow onion diced
  • 3 cloves garlic
  • 16 ounces brown mushrooms sliced

  • 2 teaspoons balsamic vinegar
  • ½ teaspoon salt
  • ½ teaspoon dried thyme
  • ¼ teaspoon black pepper

  • In a large, deep walled skillet add butter and melt over medium heat. Add in diced onions, and cook for about 3 minutes or until onions begin to brown.
  • Add in the pressed garlic and cook for an additional minute.
  • Add in the sliced mushrooms and cook for about 7 minutes or until most of the liquid from the mushrooms has evaporated.
