Cook Deep Dish Vegetarian Quiche Like This

Step 1: Prepare the Crust
Begin by preheating your oven to 375°F (190°C). In a large mixing bowl, combine the all-purpose flour and salt. Add the ice-cold butter cubes and use a pastry cutter or your fingers to work the butter into the flour until the mixture resembles coarse crumbs. Gradually add the ice-cold water, one tablespoon at a time, mixing until the dough holds together. Form the dough into a disc, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
Step 2: Roll Out the Dough
After chilling, place the dough on a lightly floured surface. Using a rolling pin, roll the dough into a circle about 12 inches in diameter. Carefully transfer the rolled-out dough to your pie dish, pressing it gently into the corners. Trim any excess dough hanging over the edges.
Step 3: Pre-bake the Crust
To prevent a soggy bottom, pre-bake the crust for about 10 minutes in the preheated oven. Remove it from the oven and set aside to cool slightly.
Step 4: Prepare the Filling
In a large bowl, whisk together the eggs and half & half until well blended. Stir in the shredded fontina cheese, Italian seasoning, salt, onion powder, garlic powder, and black pepper. Mix in the thawed spinach, sun-dried tomatoes, and feta cheese (or olives if you prefer).
Step 5: Assemble the Quiche
Pour the filling mixture into the pre-baked crust, spreading it evenly.
Step 6: Bake the Quiche
Bake the quiche in the oven for 45-50 minutes, or until the edges are golden brown and the filling is set. A knife inserted into the center should come out clean.
Step 7: Cool and Serve
Once baked, allow the quiche to cool for at least 15 minutes before slicing. This resting time helps the filling set further, making it easier to cut clean slices. Serve warm and enjoy!

Problems & Prevention
To ensure the perfect Deep Dish Vegetarian Quiche, consider these tips:
- Make sure your butter is well-chilled to create a flaky crust.
- Don’t skip the pre-baking step; it’s essential for a crisp crust.
- Let the quiche cool before slicing to prevent the filling from spilling out.
- Store leftovers in an airtight container to keep them fresh.
Best Ways to Store
To store your Deep Dish Vegetarian Quiche, allow it to cool completely before wrapping it tightly in plastic wrap or aluminum foil. It can be refrigerated for up to 3 days. If you wish to store it longer, consider freezing individual slices wrapped in plastic and placed in a freezer-safe bag for up to 3 months. Reheat in the oven or microwave before serving.
Handy Q&A
Can I make the crust ahead of time?
Absolutely! You can prepare the crust a day in advance. Just wrap it tightly and store it in the refrigerator until you’re ready to use it.
What can I substitute for fontina cheese?
If fontina cheese isn’t available, white cheddar or mozzarella are great alternatives that will still give you that creamy texture.
Can I add more vegetables to the filling?
Yes! Feel free to add your favorite vegetables. Just make sure to sauté any fresh vegetables beforehand to reduce moisture in the quiche.
How do I know when the quiche is done baking?
The quiche is done when the edges are golden brown and the center is set. You can check for doneness by inserting a knife into the center; it should come out clean.
