Ingredients  

  • 3 tbsp softened butter, divided
  • 1 lb fresh asparagus, sliced into ½-1 inch pieces
  • 1/2 lb mushrooms, sliced
  • 1 cup peas, frozen
  • 1/2 tsp teaspoon salt
  • 1 tsp Italian seasoning
  • 1/4 tsp teaspoon black pepper
  • 1 tsp minced garlic
  • 1 refrigerated pie crust
  • 5 eggs
  • 1/8 tsp nutmeg
  • 1 1/2 cups shredded cheese, I used a blend of mozzarella and sharp cheddar

Instructions 

  1. Preheat oven to 350
  2. In a large skillet, melt 1-2 tablespoons butter over medium-high heat. Add cut asparagus and mushrooms and cook until tender. After a few minutes, add frozen peas. Cook until tender, about 6-8 minutes. Season with salt, pepper, Italian seasoning and garlic.
  3. Take premade pie crust* and unroll onto 9” pie plate. Spread the remaining tablespoon of butter on it.
  4. Whisk eggs in a medium bowl. Add in cooked asparagus mixture, nutmeg and cheese.
  5. Sprinkle more cheese on top, if desired.
  6. Bake for 40-45 minutes, or until center is set.

Notes

*You may need to let your pie crust reach room temperature first. Follow directions on pie crust.
To make a crustless quiche: Follow the same instructions without using a pie crust to make this crustless asparagus mushroom quiche.
STORAGE:
  • To pre-make quiche ahead of time: You can bake this easy vegetarian quiche recipe ahead of time and then chill it and have it available to reheat the next day. You could also technically make the filling ahead of time and store it in the fridge (few days max) until you're ready to bake! 
  • To freeze quiche: You can freeze quiche either before or after baking. If freezing after baking, allow it to fully cool and then wrap foil or saran wrap over the quiche. I like to add it to a freezer bag to protect it a little more. Make sure you squeeze the air out! When rebaking, bake for 15-20 minutes or until heated through, at 350-400 degrees.  For unbaked frozen quiche, add 15-20 minutes to the total cooking time. They make the best freezer meals for new moms!
