Ingredients
  • 1 tablespoon olive oil
  • 1 large yellow onion, thinly sliced
  • 2 TBSP butter, unsalted
  • 1 pound of mushrooms, chopped
  • 2 cloves of garlic, minced
  • ½ tsp thyme
  • ½ tsp sea salt
  • ½ tsp cracked black pepper
  • ¼ cup white wine
  • 2 TBSP balsamic vinegar
  • 1 cup of smoked cheddar, grated
  • 2 sheets of thawed puff pastry or 1 can of biscuit dough or both
  • egg wash (1 egg and 1 TBSP water beaten together)
Instructions
  1. Preheat oven to 400 degrees. Heat the olive oil in a wide, heavy-bottomed pan over medium-low heat and add the onions. Cook, stirring occasionally, until they begin to caramelize, about 20 minutes.
  2. Add the butter to the pan. Once melted, add the mushrooms and saute, stirring occasionally, until they are completely soft and all of the liquid evaporates, about 20 minutes. Add the garlic and the thyme and saute until fragrant, about 1 minute. Season with salt and pepper to taste. Add the wine, scraping the bottom of the pan to pull up all of the browned bits, and cook until all of the liquid has evaporated. Remove from heat.
  3. Unfold the thawed sheets of puff pastry and cut out circles from the dough, placing them evenly spaced into a muffin tin or if using biscuit dough then cut out into circles and place on baking sheet. Top the rounds of puff pastry or biscuit rounds with a small spoonful of the onion and mushroom mixture. Top with the shredded cheese. Brush the edges of the dough rounds with the egg wash and place another round on top sealing with your fork. If you are using the muffin tins and puff pastry then just brush the sides with the egg wash.
  4. Bake until the pastry is golden brown, about 15 to 25 minutes. Garnish with fresh chopped parsley, green onions or chives.
