To-Die-For Mushroom Quiche Recipe: Meet Your Favorite New Quiche Recipe

Many people think quiche is a French recipe, but quiche originated in the medieval kingdom of Lothringen, under German rule, where it was called Lothringer speckkuchen. We know people will have strong opinions about this, so we're giving credit to both countries. This easy mushroom quiche recipe is so tasty, you won't care where it came from.

Cuisine: French/German
Prep Time: 5 minutes
Cook Time: 1 hour
Total Time: 1 hour and 5 minutes
Servings: 4 to 6


  • 1 unbaked deep-dish pie crust
  • 4 cups sliced fresh mushrooms (button, baby bella, cremini, shiitake, oyster, your favorite mushroom or a combination)
  • 1/2 cup chopped onion
  • 1 tablespoon butter
  • 1 cup shredded cheddar cheese, white cheddar cheese, gouda, fontina or your favorite cheese
  • 2 tablespoons flour
  • 1 1/4 cups whole milk
  • 4 eggs, beaten
  • 1 tablespoon minced fresh thyme
  • cayenne pepper, to taste

Here's how to make it: 

  1. Bake the pie crust in a preheated 425-degree F oven until golden, about 8 minutes. Remove and set aside. Reduce the oven temperature to 350 degrees F. 
  2. Heat the butter in a skillet. Cook the mushrooms and onion until tender, about 6 to 7 minutes. 
  3. In a bowl, combine the cheese, milk, flour, eggs, thyme, cayenne pepper, to taste, and salt and pepper. Whisk to combine. Stir in the mushrooms and onions. Pour into the pie crust.
  4. Bake for about 40 to 45 minutes or until quiche is set.
