Mushroom Swiss Quiche

This Mushroom Swiss Quiche is a hearty, flavorful quiche that is baked up in a buttery flakey crust.

To me, quiche is one of those misunderstood foods. Many times they are placed on tea party tables or served in ladies’ brunch-style settings. But quiche is more than just a delicate dish to be served at only the uppity parties. It can be a hearty meal with lots of flavors.

Often they are filled with all the goodness as an entire meal. Meats, dairy, veggies, and carbohydrates. This Mushroom and Swiss Quiche is delicious and served hot or chilled. Which makes it a perfect summer meal whether you are having people over or looking for a great way to have leftover lunches in a snap.

The dough is ready when it all comes together in a ball. Take the dough out and roll it out onto a floured surface.

Place into a waiting pie dish and pop it in to the fridge while the oven heats up. To ensure the crust is properly baked through, see blind baking tip below.

*Pro Tips

  • Using a piece of parchment paper to roll the dough out on makes for easier clean up and transferring to the pie pan. You simply flip it over onto the pie dish with your palm in the middle and peel away the parchment paper.
  • Roll out pie dough, shape the edges. Once fitted to pie pan, pop it back into the fridge until the oven is ready to keep the dough chilled. This makes for a flakier crust.
  • Blind Bake– Before filling the pie crust with the quiche batter, blind bake the crust by putting a piece of parchment paper inside the crust and some weights (dried beans work great) then baking for 15 minutes at 375℉.

Directions For The Filling

Start by preheating your oven to 375°F. Heat a skillet and add the butter.

Absolutely! Store-bought crusts will work just fine for this recipe
