Equipment

Ingredients
  

  • 4 cups zucchini thinly sliced (approx. 2 medium zucchini)
  • 1 cup yellow onion
  • ½ cup butter
  • ¼ tsp oregano
  • ¼ tsp sweet basil
  • ¼ tsp garlic powder
  • 2 tbsp parsley flakes
  • ½ tsp salt
  • ½ tsp black pepper
  • 2 cups shredded mozzarella freshly shredded
  • 2 eggs
  • tbsp dijon mustard
  • 1 pie crust like this one found in freezer section

Instructions
 

  • Preheat oven to 375 degrees
  • Remove frozen pie crust from freezer and bring to room temperature on counter while you prepare the quiche filling
  • Thinly slice 2 medium zucchini horizontally into coin shaped slices. I try to make zucchini slices approx 1/8" thick.
  • Dice the yellow onion. You will want approx 1 cup.
  • In a large skillet or fry pan, melt 1/2c butter over medium heat. Add zucchini and onion and cook until tender while stirring occasionally. 
  • While veggies are cooking, crack 2 eggs into a large bowl. Using a fork or a whisk, beat eggs for approx 30 seconds. 
  • Grab a small bowl to mix a spice blend. Add 1/4t oregano, 1/4t sweet basil, 1/4 t garlic powder, 2T parsley flakes, 1/2 t salt, and 1/2 t pepper . Stir with a fork to combine spices, and pour the spice blend into the bowl of egg stirring until completely combined.
  • Stir 2 cups of fresh grated mozzarella cheese into the egg mixture. Tip: I always recommend buying a block of mozzarella and grating it yourself vs buying pre shredded. Though convenient, the shredded cheese from the grocery store has a coating added to it to prevent it from clumping, but that coating also prevents it from melting well. 
  • Stir the cooked veggies into the large bowl as well and give everything a good stir until the veggies are completed coated in the egg mixture. 
  • Your pie crust should be fairly thawed by now. Use a fork to prick uncooked pie crust a few times. Smear 1.5 T of Dijon mustard onto the inside of pie crust. Smear some up the sides of the crust as well. 
  • Pour the quiche mixture from the large bowl into the pie crust.
  • Bake at 375 degrees for 20-25 minutes or until center is cooked through and you have a slightly brown crust. Let cool for 5 minutes before cutting into it. 
  • Slice and serve. See full post for serving ideas.
