Prep Time10 minutes mins
Cook Time40 minutes mins
Total Time50 minutes mins
Servings: 6 servings
- 2 tablespoons unsalted butter
- 4 ounces mushrooms sliced (1 ½ cups)
- ½ zucchini diced (½ cup)
- ½ red onion diced (½ cup)
- 1 cup shredded white cheddar cheese divided
- 8 large eggs
- 1 cup milk
- ½ teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon oregano
- 2 tablespoons chopped parsley for garnish
Preheat the oven to 375°F. Grease a 9-inch pie dish with butter or cooking spray.
In a medium skillet over medium heat, melt the butter. Add the mushrooms and sauté until softened and browned, about 5 minutes. Add the zucchini and onion on top of the mushrooms, and cook until softened and lightly browned, about 10 more minutes. Add to the pie dish and sprinkle with ½ cup cheddar cheese.
In a large bowl, whisk together the eggs, milk, salt, pepper, and oregano until well combined. Pour the mixture over the vegetables and cheese, and sprinkle with the remaining ½ cup cheese.
Bake for 30–35 minutes, until the center sets and a knife inserted in the middle comes out clean.
Let cool for about 10 minutes before cutting and serving.
- My Top Tip: Thoroughly cook the vegetables before you add the egg mixture. If you don't cook out all of the moisture, the quiche could be liquid-y.
- Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350ºF or in the microwave until warmed through.
- Freezing: Wrap the quiche in plastic wrap and place it in a freezer-safe bag. It'll last in the freezer for up to 3 months. Thaw in the fridge overnight and reheat in the oven at 350ºF or in the microwave until warmed through.
