Ingredients

Here’s what you’ll need to make one 9-inch vegetarian quiche. For added convenience, you’ll find the key ingredients highlighted in the table below.

Equipment

• 9-inch pie dish or tart pan
• Mixing bowls (medium and large)
• Measuring cups and spoons
• Whisk
• Spatula or wooden spoon
• Nonstick skillet
• Baking sheet (optional, for easier oven transfer)
• Knife and cutting board
• Oven mitts
• Cooling rack (optional)

Instructions

1. Preheat the oven to 375°F (190°C). If using a homemade crust, roll it out and fit it into your 9-inch pie dish. Trim and crimp the edges as desired.
2. Blind bake the crust: Line the crust with parchment paper and fill with pie weights or dried beans. Bake for 12-15 minutes, then remove the weights and parchment. Continue baking for 5 more minutes until slightly golden. Let cool slightly.
3. Prepare the vegetables: While the crust bakes, heat olive oil in a nonstick skillet over medium heat. Add onions and sauté for 2-3 minutes until just translucent.
4. Stir in bell pepper and mushrooms. Cook for another 3-4 minutes, until softened and any moisture from the mushrooms has evaporated.
5. Add broccoli and cook for 2 more minutes. Toss in the garlic and spinach, stirring until spinach wilts. Remove from heat and allow to cool for a few minutes.
6. Whisk the egg mixture: In a large mixing bowl, whisk together eggs, milk, salt, pepper, and nutmeg until smooth.
7. Assemble the quiche: Spread the sautéed vegetables evenly in the cooled pie crust. Top with shredded Gruyère cheese.
8. Pour the egg mixture gently over the vegetables and cheese, tapping the dish lightly to help the custard settle and eliminate air pockets.
9. Bake: Place the quiche on a baking sheet (for easy transfer) and bake for 35-40 minutes, or until the center is just set and the top is lightly golden.
10. Cool and garnish: Remove from oven and let cool for at least 15 minutes before slicing. Sprinkle with fresh chives or parsley for a fresh finish.

Pro Tip: If you notice the edges of your crust browning too quickly, cover them with a strip of foil or a pie crust shield about halfway through baking.

Tips & Variations

• Make it vegan: Use a vegan pie crust, substitute eggs with a chickpea flour “egg” mixture, and swap dairy milk and cheese for plant-based alternatives. Need inspiration? Check out my Vegan Bechamel Sauce Recipe for Creamy Pasta Dishes.
• Change the vegetables: Try roasted zucchini, asparagus, sun-dried tomatoes, or caramelized leeks. Leftover cooked veggies also work well.
• Mix up the cheese: Feta, goat cheese, or even a sharp cheddar can add a new twist. For a lighter version, use part-skim mozzarella.
• Crustless quiche: Skip the crust for a lower-carb, gluten-free option—just grease the pie dish well before adding the filling.
• Spice it up: Add a pinch of cayenne, smoked paprika, or fresh herbs like dill and basil to the egg mixture for more flavor.
• Meal prep: Quiche can be baked in advance and refrigerated for up to four days. It also freezes well—just thaw and reheat gently.
