Simple Mixed Vegetable Quiche

Simple Mixed Vegetable Quiche makes a bright, homey meal you can serve for breakfast, lunch, or a light dinner. This version uses a flaky crust, fresh vegetables, eggs, and a touch of cheese for creaminess without fuss.

You can try a crustless take if you want a lighter option; see a crustless version for reference at crustless vegetable quiche ideas.

What makes this quiche so appealing

This quiche feels friendly and seasonal. Roast or sauté whatever vegetables you have bell peppers, zucchini, spinach, mushrooms, and onions all work well and they turn into a flavorful, tender filling. The recipe is simple enough for a weeknight and flexible enough for weekend brunch.

You’ll notice cozy, familiar flavors from everyday ingredients: eggs, milk, and a modest amount of cheese bind the vegetables into a sliceable, satisfying pie. If you want a matching main for a casual meal, a quick stir-fry makes a nice contrast; try pairing with a simple stir-fry idea at chicken and vegetable stir-fry suggestions.

Ingredients and substitutions

Below is what you’ll need and how to swap items to match your pantry or diet.

What you’ll need for this recipe

• 1 pie crust (store-bought or homemade, 9-inch)
• 4 large eggs
• 1 cup whole milk or half-and-half (use plant milk + 2 tbsp vegan cream for dairy-free)
• 1 cup mixed vegetables, chopped (bell pepper, zucchini, spinach, mushrooms, onion)
• 1 cup grated cheese (cheddar, Gruyère, or a blend)
• 1 tbsp olive oil
• 1/2 tsp salt and 1/4 tsp black pepper
• 1/2 tsp dried thyme or a handful of fresh herbs
• Optional: 1 clove garlic, minced

Smart swaps for dietary needs

• For a lighter quiche, use 2 eggs + 2 egg whites and 3/4 cup milk.
• For dairy-free, swap cheese for a dairy-free melting alternative and use unsweetened oat or soy milk with a tablespoon of neutral oil for richness.
• For a gluten-free crust, use a premade gluten-free pie crust or make a simple almond-flour crust.
• If you want a crustless version, skip the crust and bake in a greased pie dish; you’ll find a crustless approach helpful at crustless vegetable quiche ideas.

Smart variation (optional)

Add a teaspoon of smoked paprika for a warm note, or fold in a handful of cooked potatoes for a heartier slice.

How to make Simple Mixed Vegetable Quiche

Follow these clear steps to cook the quiche from start to finish. The method keeps the filling moist but not soggy and the crust crisp.

Step-by-step cooking instructions

1. Preheat oven to 375°F (190°C).
2. Blind-bake the crust: line the pie crust with parchment and fill with pie weights or dried beans. Bake 12 minutes, remove weights, and bake 5 more minutes until lightly golden.
3. While crust bakes, heat oil in a skillet over medium heat. Add onion and sauté 3–4 minutes until soft. Add mushrooms or firmer vegetables and cook until just tender. Stir in spinach until wilted. Season with salt, pepper, and garlic if using. Remove from heat and let cool slightly.
4. In a bowl, whisk eggs, milk, herbs, and cheese. Stir in the cooled vegetables.
5. Pour the filling into the pre-baked crust and smooth the top.
6. Bake 35–40 minutes, or until the center sets and a knife inserted near the center comes out mostly clean.
7. Let rest 10–15 minutes before slicing. This helps the quiche hold its shape.

Step	Details
1	Preheat oven to 375°F (190°C) and blind-bake crust for a crisp base.
2	Sauté vegetables until tender; cool slightly before mixing with eggs and milk.
3	Bake filled quiche 35–40 minutes until set; rest before slicing.

Tips for texture, timing & tools

• Use a metal pie pan for a crisper crust; glass holds heat longer and may overbake the edges.
• Avoid overfilling; the custard rises a little while baking.
• Let the quiche cool enough to slice cleanly; 10–15 minutes is usually enough.
• If vegetables release a lot of moisture (like mushrooms), cook them until the liquid evaporates to prevent a watery filling.
• For even cooking, rotate the pan halfway through baking.

Storage, reheating

How to store it right

Cool the quiche completely, then wrap tightly in plastic wrap or store in an airtight container. Keep in the refrigerator for up to 4 days. For longer storage, freeze slices wrapped in foil and bagged for up to 2 months.

Reheating without losing flavor

Reheat slices in a 350°F (175°C) oven for 10–12 minutes, or until warm through. Microwaving works for a quick snack (about 1–2 minutes), but the crust will soften.

A dish worth making again and again

This recipe rewards improvisation: swap vegetables by season, change herbs, and adjust cheese to taste. It stores well, reheats nicely, and doubles easily for a crowd.

FAQs

Can I make this quiche ahead of time?

Yes. You can assemble and refrigerate the filled quiche for up to 24 hours before baking. Add a few extra minutes to the baking time if baking straight from chilled.

Can I freeze the baked quiche?

Yes. Freeze whole or sliced quiche wrapped tightly for up to 2 months. Thaw overnight in the fridge and reheat in the oven.

Can I use frozen vegetables?

You can. Thaw and drain them thoroughly, then sauté briefly to remove excess moisture before adding to the filling.

How do I prevent a soggy crust?

Blind-bake the crust and avoid excess liquid from vegetables. Cook watery veggies until their juices evaporate, and drain if needed before adding.
