Ingredients

Quiche Mixture

  • 6 eggs
  • 2 cups spaghetti squash (cooked and shredded)
  • 1/2 cup plain Greek yogurt
  • 2 tbsp buffalo sauce
  • 3/4 tsp sea salt
  • 3/4 tsp black pepper

Toppings

  • 1/2 cup mozzarella cheese, shredded
  • 3-4 grape tomatoes, thinly sliced into circles

Instructions

  1. Preheat Oven: Preheat your oven to 375 degrees Fahrenheit to ensure it reaches the right temperature for even baking.
  2. Prepare Quiche Mixture: In a large bowl, whisk together the 6 eggs, 2 cups cooked spaghetti squash, 1/2 cup plain Greek yogurt, 2 tablespoons buffalo sauce, 3/4 teaspoon sea salt, and 3/4 teaspoon black pepper until the mixture is smooth and well combined.
  3. Assemble in Baking Dish: Grease a pie pan or baking dish lightly with cooking spray or butter. Pour the egg and spaghetti squash mixture into the dish. Sprinkle half of the shredded mozzarella cheese evenly over the mixture. Arrange the thinly sliced grape tomato circles evenly across the surface, then finish by sprinkling the remaining mozzarella cheese on top.
  4. Bake: Place the dish into the preheated oven and bake for 28 to 32 minutes. Bake until the eggs are fully set in the center and the edges turn a light golden brown, indicating it is cooked through and slightly crispy on the edges.
  5. Cool and Serve: Remove from the oven and allow the quiche to cool for 10 to 15 minutes. Cooling helps it firm up, making it easier to slice and serve without falling apart.
