Mushroom Quiche

When you’ve ever been to brunch at my home, you understand how I really feel about quiche. I LOVE IT… and I all the time have one on the desk able to be devoured! And though I’ve tons of quiche recipes, I’ve two which might be virtually all the time on my menu: Quiche Lorraine and this wonderful bacon, onion, and mushroom quiche!

Make the Crust

In relation to making a flaky crust, the secret’s to begin with chilly substances, and maintain all the pieces chilly in the course of the course of. When you begin to see melting butter at any level, cease, cowl the bowl, and pop it within the fridge for 20 minutes or so, then resume. In any other case your butter will leak out of the crust whereas baking, and can yield a dry, flake-less, flavorless crust. COLD IS KEY!

Why Blind Bake?

Blind baking takes additional effort and time, but it surely’s an important step for baking a quiche, which has a really moist filling. The purpose of blind baking is to permit the crust to partially prepare dinner and brown earlier than it’s stuffed with the moist filling, in order that it bakes up crisp, and doesn’t change into soggy. Fortunately, blind baking isn’t onerous and solely requires some parchment paper and dried beans or pie weights.

The Quiche Filling

  • Bacon: This could simply be substituted with diced pancetta and even cooked and crumbled sausage. When you’re a vegetarian, you could omit it fully.
  • Olive Oil: No have to get fancy right here; use no matter you’ve got available!
  • Onion: I like yellow onion right here, however in a pinch white onion and even crimson onion will work simply tremendous!
  • Mushrooms: I desire cremini mushrooms… however white button or child portobello mushrooms will work.
  • Salt and Pepper: Provides seasonings and spice.
  • Thyme: You should definitely use FRESH thyme leaves, which provides each a pop of freshness and earthiness.
  • Dijon Mustard: I like Gray Poupon, however use no matter model you’ve got available or love.
  • Heavy Cream: That is an important substances and shouldn’t be changed with all milk or half and half.
  • Milk: Entire milk aka full-fat milk works finest right here.
  • Cornstarch: That is my secret ingredient! Say bye-bye to soggy moist quiche.
  • Eggs: You should definitely use massive eggs, and convey them to room temperature in order that they bond evenly with the opposite substances.
  • Cheese: I name for gruyere, however Cheddar cheese (I’d recommend a pointy white cheddar) or Swiss are tremendous substitutes.

Make the Quiche:

  1. Make your crust: You’ll have to make the dough, chill it, roll it, then blind bake. Earlier than baking, make sure to preheat the oven to 375 levels.
  2. Fry the bacon. Then drain it on a paper towel and chop it into tiny items.
  3. Prepare dinner the onions. You’ll add them into the bacon grease, scale back to medium warmth, and prepare dinner till they’re caramelized.
  4. Sauté the mushrooms till they’re crispy. Be sure to prepare dinner all of the water off of them, in any other case they’ll leak it into the quiche combination, which might trigger a soggy filling.
  5. Whisk collectively the cream, eggs, milk, salt, pepper, cornstarch.
  6. Sprinkle cheese and bacon on the crust, then high with the mushroom/onion combination.
  7. Pour within the egg combination and bake! Till the middle is about and the crust is golden brown.
  8. Cool for no less than quarter-hour earlier than serving heat… or cool fully and serve at room temperature!
