Description

This mushroom quiche recipe is filled with tender sautéed mushrooms, shallots, fresh rosemary, cheese and eggs then baked in a ready-made crust!


Ingredients

Units Scale
  • 2 teaspoons avocado oil or unsalted butter
  • 2 shallots, minced
  • 10 ounces mushrooms, sliced
  • 5 large eggs
  • 1/2 cup half & half
  • 2 teaspoons Dijon mustard
  • 1/2 teaspoon salt
  • 1/2 teaspoon chopped fresh rosemary or 1 teaspoon fresh thyme or 1/2 teaspoon dry thyme
  • 1/4 teaspoon freshly ground pepper
  • 1 1/2 cups shredded Cheddar cheese (6 ounces)
  • 1 frozen pie shell

Instructions

  1. Arrange oven rack in the lower third of the oven. Preheat oven to 375 degrees F.
  2. Heat oil or butter in a large non-stick skillet over medium-high heat. Add shallots and mushrooms and cook, stirring often until the mushrooms have softened, released their juices and start to brown, 5 to 7 minutes. Scrape onto a plate to cool.
  3. Whisk eggs, half and half, mustard, salt, rosemary and pepper in a large bowl. Stir in the mushroom mixture and 1 cup (4 oz) cheese.
  4. Place the pie shell on a parchment lined baking sheet. Pour the egg mixture into the crust. Top with the remaining ½ cup (2 oz) cheese.
  5. Transfer the baking sheet to the rack in the lower third of the oven and bake until the center of the quiche is lightly puffed and the crust is golden, about 35 to 40 minutes. Let cool 10 to 20 minutes before slicing and serving.

Notes

Reheating Instructions: Reheat a slice of quiche in the airfryer on 300 degrees for 10 minutes. Reheat single slice in the oven 12 minutes at 350 degrees F. To reheat whole quiche heat at 350 degrees F until hot all the way through, or 160 degrees F, when tested with an instant-read thermometer, about 35 minutes.
