Eggs
Milk or cream
Gruyère, Swiss, or cheddar cheese (shredded)

Directions

Preheat the oven to 375°F (190°C). Roll out the pie crust and fit it into a tart or pie dish. Blind bake the crust for 10 minutes, then set aside.
Heat olive oil or butter in a skillet over medium heat. Sauté onion or leek until softened, then add garlic, mushrooms, and spinach. Cook until vegetables are tender and any excess moisture has evaporated.
Whisk together eggs, milk or cream, salt, pepper, and fresh herbs in a bowl.
Spread roasted winter vegetables and sautéed mixture evenly over the crust. Sprinkle with shredded cheese.

Storage/Reheating

Store leftover quiche in an airtight container in the refrigerator for up to 4 days. Reheat slices in the oven at 350°F for 10–12 minutes until warmed through, or microwave gently if short on time. For longer storage, freeze baked quiche (whole or sliced) for up to 2 months. Thaw in the fridge overnight before reheating in the oven.

FAQs

What kind of cheese works best?

Gruyère, Swiss, cheddar, or goat cheese all pair beautifully with winter vegetables.

Can I use frozen vegetables?
