This Easy Mushroom Quiche Recipe Is to Die For (Lunch, Brunch, Dinner) Vegetarian Brunch Dinner French Recipes Lunch Gluten-free Vegetables German Recipes

We're calling quiche night! 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.

Start by pre-baking your pie crust until golden. While the pie crust bakes, make the filing by melting butter in a skillet. Add the mushrooms (check out the health benefits of mushrooms) and onions and cook until soft. In a bowl, whisk together the shredded cheese, milk, flour, eggs, fresh thyme, ground cayenne and eggs. Add the mushrooms and onions and pour everything into the pie crust. Bake for about 40 minutes and you're ready for an amazing lunch, brunch or dinner.

Use whatever fresh mushrooms you like best – or a combination of mushrooms. Wild mushrooms would put this quiche over the top! Serve this mushroom quiche recipe with a salad for a complete meal.
