Step‑by‑Step Instructions for Autumn Vegetable Quiche
Step 1: Make the Pie Crust
In a large bowl, combine 1 ¼ cups of all-purpose flour and ½ teaspoon of salt. Cut in ½ cup of cubed cold butter until the mix resembles coarse crumbs. Gradually add 3 tablespoons of ice water, one tablespoon at a time, mixing until the dough forms. Shape the dough into a disk, wrap it tightly, and chill in the fridge for at least 30 minutes.
Step 2: Prepare the Crust for Baking
Once the dough has chilled, roll it out on a floured surface to a 9-inch circle. Fit the dough into a pie dish, trimming any excess, and prick the bottom with a fork. Line the crust with parchment paper and fill it with pie weights. Blind bake at 375°F (190°C) for about 12 minutes until lightly golden. After baking, set the crust aside to cool.
Step 3: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the sliced onion, 1 cup of sliced mushrooms, chopped zucchini, and red bell pepper, cooking for 5-7 minutes until softened and fragrant. Remove from heat and gently fold in 1 cup of roasted butternut squash. Allow the vegetable mixture to cool slightly before proceeding to the next step.
Step 4: Whisk the Egg Mixture
In a medium bowl, whisk together 3 eggs until well blended. Then stir in ½ cup of half-and-half, 2 tablespoons of freshly chopped herbs, and season with salt and pepper to taste. This custard will enhance the flavors of the Autumn Vegetable Quiche while binding the filling together beautifully.
Step 5: Assemble the Quiche
Evenly scatter the cooled vegetable mixture across the bottom of the pie crust. Next, sprinkle ½ cup of shredded Gruyère cheese over the veggies, ensuring even distribution. This will not only add a rich flavor but also create a delightful melty texture once baked.
Step 6: Pour the Custard Mixture
Gently pour the egg custard over the vegetable and cheese layers in the quiche, allowing it to seep in evenly. Ensure that the filling is well-distributed in the crust.
Step 7: Bake the Quiche
Carefully place the assembled Autumn Vegetable Quiche in the preheated oven at 375°F (190°C). Bake for 35-40 minutes, or until the center is set and the top is golden brown. If the crust edges brown too quickly, shield them with foil to prevent burning.
Step 8: Cool and Slice
Once baked, remove the quiche from the oven and let it cool for at least 10 minutes before slicing. This resting period allows the filling to set further, making it easier to serve. Now you're ready to enjoy a delicious slice of your homemade Autumn Vegetable Quiche!

Expert Tips for Autumn Vegetable Quiche
• Use Chilled Ingredients: Keep your butter and water cold to ensure a flaky crust. Warm ingredients can lead to a tough texture.
• Don’t Overmix: When combining the pie crust ingredients, mix just until combined. Overmixing can cause the dough to become rubbery.
• Add Cheeses Strategically: Layer the Gruyère cheese beneath the vegetables. This prevents it from browning too quickly and adds delicious creaminess to every bite.
• Season Wisely: Always taste your vegetable mixture before adding it to the quiche. A pinch of salt can elevate the flavor of your Autumn Vegetable Quiche significantly.
• Check Doneness: Use a knife to test the center of the quiche. It should come out clean when fully baked, ensuring a perfectly set filling.
• Storage Tip: This quiche keeps well in the fridge. For best results, store it in an airtight container, and enjoy leftovers within three days.
How to Store and Freeze Autumn Vegetable Quiche
Fridge: Store any leftover Autumn Vegetable Quiche tightly covered in an airtight container for up to 3 days. This helps maintain its delightful flavors and texture.
Freezer: If you want to save extra slices, wrap the quiche in plastic wrap and then place it in a freezer-safe bag. It can be frozen for up to 2 months.
Reheating: To enjoy your quiche again, preheat the oven to 350°F (175°C) and reheat it for about 15-20 minutes until warmed through. You can also microwave individual slices for quick meals.
Serving Tip: Allow the quiche to cool slightly before slicing and store what you won't eat right away to keep it fresh and delicious!

Make Ahead Options
Making your Autumn Vegetable Quiche in advance can be a lifesaver for busy weeknights! You can prepare the pie crust up to 24 hours ahead—just roll it out, fit it into the dish, and then cover it tightly with plastic wrap before refrigerating. The sautéed vegetable filling can also be made up to 3 days in advance; simply cool it completely and store it in an airtight container in the fridge. To maintain quality, avoid pouring the egg custard mixture until you're ready to bake. When you're set to serve, scatter the veggies and cheese in the crust, pour the custard over, and bake as directed for a fresh, delicious quiche that tastes just as good as if it were made that day!

Autumn Vegetable Quiche Recipe FAQs
How do I choose the best vegetables for my quiche?
Absolutely! For this Autumn Vegetable Quiche, aim for vibrant vegetables that are in season, like zucchini, bell peppers, and butternut squash. Look for zucchini that feels firm with a shiny skin, and select bell peppers that have a rich color and few blemishes. Avoid any that have dark spots or feel soft, as they may be overripe.
What’s the best way to store leftover quiche?
Very! Store any leftover Autumn Vegetable Quiche in an airtight container in the fridge for up to 3 days. If you want to keep its flavors fresh, wrap the quiche tightly in plastic wrap before placing it in the container. This also helps maintain its texture without it drying out.
Can I freeze my quiche, and if so, how?
Of course! To freeze your Autumn Vegetable Quiche, first let it cool completely. Wrap the quiche tightly in plastic wrap, ensuring there are no gaps to let air in, then place it in a freezer-safe bag. You can freeze it for up to 2 months. When you’re ready to enjoy it again, thaw it in the fridge overnight, then reheat in the oven at 350°F (175°C) for about 15-20 minutes.
What if my quiche center isn’t set after baking?
Don't worry! If your quiche isn’t set in the center after 40 minutes, it may need a little longer in the oven. Check it every 5 minutes or so. If the edges of the crust are browning too quickly, shield them with foil while continuing to bake. When the center is set, a knife inserted should come out clean.
Is this quiche safe for pets or those with egg allergies?
Good question! While the Autumn Vegetable Quiche features wholesome ingredients, it is not suitable for pets—especially because of the cheese and garlic in the herbs you may use. If making for someone with egg allergies, consider using a substitute such as a flaxseed meal mix (1 tablespoon flaxseed meal plus 2.5 tablespoons water equals one egg) to enforce the binding without using eggs.
