The sweetness of the caramelized onions complements the savory mushrooms, all enveloped in a creamy, cheesy filling. It’s the perfect dish for brunch, a light lunch, or a comforting dinner.

Ingredients

  • One nine-inch pie shell
  • 2 tablespoons olive oil
  • 2 large white onions, thinly sliced
  • 2 cloves garlic, minced
  • 1/2 teaspoon dried chilli flakes
  • 8 ounces mushrooms, sliced
  • 1 teaspoon dried thyme
  • 3 large eggs
  • 1 cup half and half cream
  • 1 cup grated havarti cheese
  • Salt and pepper to taste

Instructions

  1. Preheat your oven to 400°F (200°C). Dock the pie shell with a fork and bake for 10 to 15 minutes until it is lightly golden.
  2. While the pie shell is baking, heat the olive oil in a large skillet over high heat. Add the onions, garlic, and chilli flakes. Cook until the onions are caramelized, about ten minutes.
  3. Add the mushrooms to the skillet and continue to cook on high until the mushrooms are also caramelized, about five minutes.
  4. Remove the skillet from the heat and stir in the thyme, salt, and pepper. Set aside to cool slightly.
  5. In a large bowl, beat the eggs together with the cream and half of the grated cheese.
  6. Stir the onion and mushroom mixture into the egg mixture and mix well.
  7. Place the pre-baked pie shell on a cookie tray to catch any potential overflow. Pour the filling into the pie shell.
  8. Sprinkle the remaining cheese on top of the filling.
  9. Reduce the oven temperature to 375°F (190°C) and bake the quiche until the filling is set and the top is golden, about 25-30 minutes.
  10. Allow the quiche to cool for a few minutes before serving. Enjoy it warm from the oven.

Tips

To ensure your quiche bakes evenly, consider using a pie crust shield or tin foil to protect the edges from over-browning. Allow the quiche to cool slightly before slicing to help it set completely. Pair it with a simple green salad or a warm cup of soup for a complete meal.

Variations & Substitutions

Feel free to experiment with this recipe by adding your favorite vegetables such as spinach or bell peppers. For a different flavor profile, swap out the havarti cheese with gruyère or cheddar. If you prefer a spicier dish, increase the amount of chilli flakes or add a dash of hot sauce to the egg mixture.

Storage

Store any leftover quiche in an airtight container in the refrigerator for up to three days. To reheat, place slices in a preheated oven at 350°F (175°C) until warmed through. You can also freeze the quiche for up to a month. Be sure to wrap it tightly in plastic wrap and foil before freezing.
