Cheese and Mushroom Quiche

We love this fluffy Cheese and Mushroom Quiche. It has an incredible creamy texture that melts in your mouth. Pair that with a flaky buttery crust, Gruyère cheese, sauté mushrooms, and it tastes heavenly. Quiche makes a great breakfast, brunch, or dinner. Yum!

  • 1 9" unbaked pie shell frozen, or refrigerated
  • 2 teaspoons olive oil
  • 1 pound assorted mushrooms, trimmed & sliced
  • 1/2 medium onion sliced
  • 5 large eggs
  • 1 cup half & half
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 1 cup Gruyère or Swiss Cheese shredded
  • 1 tablespoon chives chopped (optional for the top)


  • Preheat oven to 350o F, and set the oven rack to the bottom of the oven.
  • Blind bake the pie shell by placing a piece of parchment paper over the pie dough, and fill it with dried beans or pie weights. Then, place it on a baking sheet, and bake 10-15 minutes until light golden brown. Remove from the oven, let cool, then remove the pie weights and parchment paper. Next, poke the bottom of the crust with a fork, and return to oven to bake for an additional 10 minutes, or until golden brown.
  • Meanwhile, cut the mushrooms and onion. Then, heat a large skillet with the oil and add the mushrooms & onions. Heat 5-6 minutes until all moisture is gone, mushrooms are browned, and onions have softened. Set aside.
  • Make the filling. In a large bowl, whisk together eggs, half & half, salt and pepper.
  • Add the mushrooms & onions, cheese, & egg mixture into the pie shell. Leave at least 1/4" from the edge.
  • Bake for 30-35 minutes, or until slightly brown on top and the center is a little jiggly. Let cool for 5-10minutes before slicing and serving.
  • Sprinkle green onions on top. (optional) Cut & serve. Tastes best out of the oven still hot.
