Ingredients

Scale
  • 1 frozen deep dish pie shell, thawed
  • 2 tbsp oil
  • 8 oz sliced fresh mixed mushrooms – crimini, shiitake, and oyster

  • 1 1/2 cups shredded Gruyère cheese, divided

Instructions

  1. Preheat oven to 375°F.
  2. Heat oil in a large nonstick skillet over medium-high heat. Add mushrooms; cook, stirring occasionally, until browned and tender, about 10 minutes. Add spinach; cook, tossing constantly, until wilted, about 2 minutes.
  3. Spoon mushroom-spinach mixture evenly into pie crust. Set aside.
  4. In a medium bowl, whisk eggs, milk, mustard, mustard, herbs, onion powder, garlic salt, salt and pepper. Fold in half the Gruyère cheese.
  5. Pour eggs into pie crust, covering the mushroom mixture. Sprinkle top with remaining cheese.
  6. Bake until set and golden brown, about 40-45 minutes. Remove from oven and let stand for 10 minutes before serving.

Tips:

  • For a different flavour profile, substitute Gruyère cheese with another type of shredded cheese, such as Cheddar, Swiss, or Gouda.
  • Make this quiche ahead of time; cover and refrigerate for up to 3 days.
