Swiss Cheese Spinach and Mushroom Quiche with Crispy Potato Crust

With winter fading into the background, I have been eager to whip up as many comfort foods as I can. I still eat a few casseroles here and there in summer, but I tend to eat on the lighter side when it’s hot out. So, with the still chilly air, I feel like I need to stock up on warm, yummy, comforting food that I won’t be enjoying again for a few months.

Today I have decided to share one of my favorite comforting dishes. This quiche has a crispy potato crust and is filled with Swiss cheese, mushrooms, spinach, and eggs. I love having this with a big, full-bodied glass of wine and a light soup or salad to start. Hope you enjoy!

To begin, preheat your oven to 400 degrees F. Butter a 9-inch pie plate with 1 tablespoon (or less) of butter. Using the large holes on a box grater, shred the potatoes.

In a large bowl, mix the potatoes, onion, cornstarch, ½ teaspoon salt and ¼ teaspoon pepper.

In a large nonstick skillet, melt 1 tablespoon butter. Transfer the potato mixture to the skillet and pat into a 10-inch disk. Cook about 10 minutes until the bottom is golden brown.

Loosen potatoes and place pie plate top side down onto crust. Flip over, browned side up, onto the pie plate. Using your palm, move crust so edges are even around rim of plate. Bake about 20 minutes.

While the crust is baking, heat the skillet over high heat. Add the spinach and ¼ cup water. Keep turning with a tongs until completely wilted. When cool enough to touch, squeeze out as much water as possible by hand, then wrap in paper towels and squeeze again. Chop in small pieces. Reserve.

Heat 1 tablespoon butter in the same skillet over medium heat. Add the mushrooms and cook until brown and liquid has evaporated, stirring several times, about 10 minutes. Add the spinach to the mushrooms and season with salt. Put half of the spinach mushroom mixture in the crust, sprinkle the Swiss cheese evenly over, then the parmesan. Put the remaining spinach mixture on top.

In a bowl, mix together the eggs, egg whites, milk, ½ teaspoon salt, and ¼ teaspoons pepper and nutmeg.

Pour over the filling in the pie plate. Elevate the top mushrooms that are submerged so they will show when finished – you want it to be pretty! Bake 20-25 minutes until set. Let cool about 20 minutes before cutting.
