What Makes This Quiche Different?
Traditional quiche recipes often require making a pie crust from scratch, chilling dough, and rolling it out. While those crusts are delicious, sometimes we just need something simple.
This sourdough discard crust comes together quickly with only two ingredients and creates the perfect base for a hearty vegetable filling. It's slightly tangy from the sourdough discard and beautifully complements the savory eggs and vegetables.
It's also a wonderful recipe for reducing food waste. Instead of tossing extra vegetables or sourdough discard, you can transform them into a nourishing meal the whole family will enjoy.
Best Vegetables for Veggie Quiche
The beauty of this recipe is that almost any vegetable works. Some of our favorites include:
- Spinach
- Kale
- Zucchini
- Bell peppers
- Mushrooms
- Broccoli
- Asparagus
- Onions
- Green onions
- Cherry tomatoes
- Sweet potatoes
- Roasted vegetables
For the best texture, lightly sauté vegetables that release a lot of moisture, such as mushrooms, zucchini, and spinach. This helps prevent a watery quiche.
