Caramelized Onion and Mushroom Quiche

Picture this: a golden-brown, savory quiche with a perfectly flaky crust, filled with the rich flavors of caramelized onions and earthy mushrooms. It’s a dish that’s as delightful to the eyes as it is to the taste buds.


  • 1 pre-made pie crust
  • 2 large onions, thinly sliced
  • 8 oz mushrooms, sliced
  • 1 cup shredded Gruyère cheese
  • 4 large eggs
  • 1 cup heavy cream
  • Salt and pepper to taste
  • 2 tablespoons olive oil


  1. Preheat your oven to 375°F (190°C).
  2. In a large skillet, heat the olive oil over medium-low heat. Add the sliced onions and cook, stirring occasionally, until they turn a deep golden brown, about 20-25 minutes.
  3. Add the sliced mushrooms to the caramelized onions and cook for an additional 5 minutes until they’re tender.
  4. While the onion and mushroom mixture cools slightly, whisk together the eggs and heavy cream in a bowl. Season with salt and pepper.
  5. Place the pre-made pie crust in a pie dish. Spread the caramelized onion and mushroom mixture evenly over the crust. Sprinkle the shredded Gruyère cheese on top.
  6. Pour the egg and cream mixture over the filling.
  7. Bake in the preheated oven for 35-40 minutes or until the quiche is set and the top is golden brown.
  8. Remove from the oven and let it cool slightly before slicing.
