Key Ingredients & Notes

Pie Crust
Use a 9-inch (23 cm) pie crust. Store-bought saves time, but homemade gives a richer flavor. For tips on perfect crust texture, explore baking techniques from King Arthur Baking.

Fresh Spinach (2 cups / 60g)
Fresh spinach wilts beautifully and keeps a vibrant color. Frozen spinach works too, just squeeze out excess water thoroughly to avoid a watery quiche.

Mushrooms (1½ cups / 150g, sliced)
Cremini or button mushrooms are ideal. Sauté until golden to deepen flavor. Mushrooms are rich in nutrients, as explained by Healthline.

Eggs (5 large)
Eggs form the custard base. Use room temperature eggs for smoother blending.

Milk or Cream (1 cup / 240 ml)
Heavy cream creates a richer texture, while whole milk keeps it lighter. A mix of both is ideal.

Cheese (1 cup / 100g)
Gruyère, Swiss, or cheddar melt beautifully. Gruyère adds a nutty depth that pairs perfectly with mushrooms.

Onion or Shallot (¼ cup / 40g)
Adds subtle sweetness and aromatic depth.

Garlic (2 cloves)
Enhances the savory profile.

Olive Oil or Butter (1 tablespoon / 15g)
Used for sautéing and building flavor.

How to Make Easy Spinach Mushroom Quiche

1. Preheat the Oven
   Set oven to 375°F (190°C). Place rack in the center.
2. Prepare the Crust
   Fit your crust into a 9-inch (23 cm) pie dish. Prick the base with a fork. Pre-bake for 8 to 10 minutes for a crisp base.
3. Sauté the Vegetables
   Heat oil or butter in a skillet over medium heat. Add onions and cook for 2 to 3 minutes until soft. Add mushrooms and cook 6 to 8 minutes until golden and moisture evaporates.
4. Add Spinach
   Stir in spinach and cook until wilted, about 2 minutes. Remove from heat and let cool slightly.
5. Whisk the Custard
   In a bowl, whisk eggs, milk or cream, salt, and pepper until smooth.
6. Assemble the Quiche
   Spread the vegetable mixture evenly in the crust. Sprinkle cheese on top. Pour egg mixture gently over everything.
7. Bake
   Bake for 35 to 45 minutes until the center is just set. The edges should be lightly golden and the center slightly wobbly.
8. Cool and Serve
   Let rest for 10 to 15 minutes before slicing. This helps the custard fully set.

Pro Tips for Success
