Description

Delectable French Onion and Mushroom Tart with Gruyere Cheese


Ingredients

Scale
  • 1 sheet puff pastry, thawed
  • 2 tbsp unsalted butter
  • 4 large yellow onions, thinly sliced
  • 8 oz cremini mushrooms, sliced
  • 2 garlic cloves, minced
  • 1 tsp fresh thyme, chopped
  • 1/4 cup dry white wine
  • 1 cup shredded Gruyere cheese
  • Salt and pepper to taste

Instructions

  1. Preheat oven to 400°F. Roll out the puff pastry and press it into a 9-inch tart pan with a removable bottom. Prick the bottom with a fork and bake for 10-12 minutes until lightly golden.
  2. In a large skillet, melt the butter over medium heat. Add the sliced onions and sauté for 20-25 minutes, stirring occasionally, until caramelized and golden brown.
  3. Add the sliced mushrooms and garlic to the skillet and cook for 5-7 minutes, until the mushrooms are tender. Deglaze the pan with the white wine and cook for 2-3 minutes until the liquid is mostly evaporated.
  4. Spread the caramelized onion and mushroom mixture evenly into the pre-baked tart shell. Top with the shredded Gruyere cheese.
  5. Bake the tart for 20-25 minutes, or until the cheese is melted and bubbly. Allow to cool for 5 minutes before slicing and serving.
