What Is a Vegetarian Quiche?
A vegetarian quiche is a savory baked custard made with eggs, cream or milk, cheese, and vegetables, all poured into a pastry crust and baked until just set. Think of it as a creamy, sliceable omelet wrapped in a buttery crust.
Unlike meat-based quiches, vegetarian quiche relies on layers of flavor from vegetables, herbs, and cheeses. When done right, it’s rich, balanced, and deeply satisfying—without needing bacon or sausage to shine.

Step-by-Step Guide to Making Vegetarian Quiche
Follow these clear steps for a perfectly set, flavorful vegetarian quiche.
Step 1: Prepare the Quiche Crust
In a large bowl, mix flour and salt. Cut in cold butter until the mixture looks like coarse crumbs with visible butter pieces. Add ice-cold water one tablespoon at a time, mixing gently until the dough just comes together. Shape into a disk, wrap, and chill for 30 minutes to prevent shrinking.
Step 2: Roll and Blind-Bake the Crust
Roll chilled dough into a 12-inch circle and fit into a 9-inch quiche pan. Trim edges. Preheat oven to 375°F (190°C). Line crust with parchment, fill with pie weights, and bake 15 minutes. Remove weights and bake 5–7 minutes until lightly golden.
Step 3: Prepare the Vegetables
Heat olive oil in a skillet over medium heat. Sauté onions until soft, add garlic and mushrooms until moisture evaporates, then bell peppers and zucchini for 2–3 minutes. Stir in spinach until wilted. Season lightly and remove from heat to avoid a watery quiche.
Step 4: Make the Custard Filling
Whisk eggs until smooth. Add cream or milk, salt, pepper, and a pinch of nutmeg. The mixture should be silky, not foamy.
Step 5: Assemble the Quiche
Sprinkle half the cheese into the crust. Add vegetables evenly, top with remaining cheese, then slowly pour in the custard. Gently tap the pan to release air bubbles.
Step 6: Bake the Quiche
Bake at 375°F (190°C) for 40–45 minutes until the center is just set and the top is lightly golden. Tent with foil if browning too fast.
Step 7: Rest and Serve
Let rest 10–15 minutes before slicing for clean, firm cuts.

FAQs about Vegetarian Quiche Recipe
1. Can I make vegetarian quiche ahead of time?
Yes. Vegetarian quiche often tastes even better the next day as the flavors settle. Bake it fully, allow it to cool, refrigerate, and reheat gently before serving.
2. Can I use milk instead of cream?
Yes. Whole milk works well, though cream gives the quiche a richer, silkier texture. Avoid low-fat milk, as it can make the filling watery.
3. How do I prevent a soggy quiche crust?
Blind bake the crust before filling it, and always sauté vegetables to remove excess moisture prior to assembly.
4. Can vegetarian quiche be frozen?
Absolutely. Freeze the fully baked and completely cooled quiche, tightly wrapped, for up to two months. Thaw overnight before reheating.
5. What’s the best cheese for vegetarian quiche?
Gruyère, Swiss, cheddar, and feta are excellent choices. You can use one variety or combine them for deeper flavor.
