With its golden-brown top, creamy texture, and savory depth, it’s no wonder quiche has earned a permanent spot in kitchens around the world.

The History of Quiche

Quiche traces its origins back to the Lorraine region of France, where it began as “quiche Lorraine” in the early 16th century. Originally, it was a simple open-faced pie made with eggs, cream, and bacon (then known as lardons), baked into a pastry shell. The word “quiche” itself comes from the German word “Kuchen,” meaning cake, reflecting the historical influence of Germanic culture in the Alsace-Lorraine area.

Over time, French chefs refined the recipe, introducing variations that included cheese, vegetables, and different meats. By the 20th century, quiche had gained international popularity, especially during the mid-1900s when American home cooks embraced it as part of the growing interest in European cuisine. Today, quiche is celebrated globally, with countless regional and personal adaptations — and the Spinach & Mushroom version stands out as one of the most beloved vegetarian options.

Ingredients Breakdown

The beauty of a Spinach & Mushroom Quiche lies in its balance of fresh ingredients and rich textures. Here’s a detailed breakdown of each component:

Pie Crust: A homemade or store-bought buttery, flaky crust forms the foundation. It provides a crisp contrast to the soft, creamy filling.
Eggs: The backbone of the custard, eggs bind the ingredients and create a silky texture when baked.
Cream or Whole Milk: Adds richness and smoothness to the custard. Heavy cream yields a denser, more luxurious quiche, while milk makes it lighter.
Feta or Gruyère Cheese: Feta adds a tangy bite that complements the earthiness of mushrooms, while Gruyère brings nutty depth and melts beautifully.
Mushrooms: Cremini, button, or shiitake mushrooms are sautéed until golden to intensify their umami flavor.
Spinach: Fresh baby spinach wilts quickly and contributes color, nutrients, and a mild vegetal note.
Onion and Garlic: These aromatics build flavor layers, providing sweetness and savoriness.
Olive Oil or Butter: Used for sautéing vegetables, enhancing mouthfeel and aroma.
Seasonings: Salt, black pepper, nutmeg (a classic quiche spice), and optional herbs like thyme or parsley elevate the overall taste.

Step-by-Step Recipe

Creating the perfect Spinach & Mushroom Quiche requires attention to detail at every stage. Follow these steps for a flawless result:

Prepare the Crust: If making homemade, combine 1 ¼ cups all-purpose flour, ½ teaspoon salt, and ½ cup cold unsalted butter (cubed). Cut in butter using a pastry cutter until mixture resembles coarse crumbs. Add 3–4 tablespoons ice water, one at a time, mixing until dough comes together. Flatten into a disk, wrap in plastic, and chill for at least 30 minutes. Roll out on a floured surface and fit into a 9-inch pie dish. Crimp edges, prick the bottom with a fork, and pre-bake (blind bake) at 375°F (190°C) for 12–15 minutes with pie weights or parchment and dried beans. Remove weights and bake 5 more minutes. Set aside to cool slightly.
Sauté Mushrooms: Heat 2 tablespoons olive oil in a skillet over medium heat. Add 1 diced onion and cook until translucent (about 5 minutes). Add 8 oz sliced mushrooms and a pinch of salt. Cook until mushrooms release moisture and turn golden brown (8–10 minutes). Stir in 2 minced garlic cloves and cook for 1 more minute. Remove from heat.
Wilt Spinach: In the same pan, add 4 cups fresh spinach in batches, stirring until wilted. Transfer to a colander and press out excess liquid using a spoon or paper towels. This step is crucial to prevent a watery quiche.
Make Custard: In a large bowl, whisk 4 large eggs with 1 cup heavy cream (or whole milk), ¼ teaspoon ground nutmeg, ½ teaspoon salt, and ¼ teaspoon black pepper until smooth and well combined.
Assemble the Quiche: Sprinkle half the cheese (½ cup crumbled feta or shredded Gruyère) over the pre-baked crust. Spread the mushroom mixture evenly, then layer with the squeezed spinach. Top with remaining cheese. Slowly pour the custard mixture over the fillings, ensuring it seeps into all gaps.
Bake: Place the quiche on a baking sheet (to catch spills) and bake at 375°F (190°C) for 35–40 minutes, or until the center is set and a knife inserted near the center comes out clean. The top should be golden and slightly puffed.
Cool and Serve: Let the quiche rest for 10–15 minutes before slicing. This allows the custard to firm up for cleaner cuts.

Tips for the Perfect Quiche

Pre-bake the crust: Blind baking prevents a soggy bottom, especially important with wet ingredients like spinach.
Remove moisture: Always squeeze cooked spinach thoroughly. Excess water can ruin the custard’s texture.
Don’t overfill: Leave about ¼ inch at the top of the crust to avoid spillage during baking.
Low and slow baking: Avoid high heat, which can cause curdling. Stick to 350–375°F for even cooking.
Test for doneness: The quiche is done when the center jiggles slightly but isn’t liquid. Overbaking leads to rubbery eggs.
Use room temperature ingredients: Cold eggs or cream can affect how evenly the custard sets.
Let it rest: Allowing the quiche to cool slightly enhances flavor and improves sliceability.

Variations and Customizations

One of the greatest strengths of quiche is its adaptability. Here are some creative twists on the classic Spinach & Mushroom version:

Add Protein: Include diced cooked bacon, ham, sausage, or smoked turkey for a heartier meal.
Dairy Swaps: Replace feta with goat cheese for creaminess, or use cheddar, mozzarella, or Swiss for different flavor profiles.
Gluten-Free Option: Use a gluten-free pie crust or make a crustless quiche by greasing the pan and pouring the filling directly in.
Vegan Version: Substitute eggs with silken tofu blended with plant-based milk and nutritional yeast. Use vegan cheese and a dairy-free crust.
Additional Veggies: Add roasted red peppers, caramelized onions, sun-dried tomatoes, zucchini, or artichoke hearts.
Herb Infusions: Mix in fresh dill, basil, or chives for a bright, aromatic lift.
Spice It Up: Add a pinch of red pepper flakes or a dash of hot sauce for heat.
Mini Quiches: Bake in muffin tins for adorable, portion-controlled appetizers or party snacks.

Health Considerations and Nutritional Value

While quiche is often seen as indulgent, it can be a nutritious option when prepared thoughtfully. Here’s a breakdown of its health aspects:

Spinach: Packed with iron, vitamin K, folate, and antioxidants, spinach supports bone health, blood clotting, and immune function.
Mushrooms: Low in calories and rich in selenium, B vitamins, and beta-glucans (which support immunity), mushrooms also offer a meaty texture without saturated fat.
Eggs: A complete protein source containing all essential amino acids, plus choline (important for brain health) and lutein (good for eye health).
Dairy: Provides calcium and vitamin D, though full-fat versions increase saturated fat content. For a lighter option, use low-fat milk and reduced-fat cheese.
Custard Ratio: Using more milk than cream reduces calories and fat while still maintaining creaminess.
Crust Choices: Whole wheat or almond flour crusts add fiber and nutrients compared to traditional white flour versions.
Portion Control: One slice (1/8 of a 9-inch quiche) typically ranges from 250–350 calories depending on ingredients. Serve with a side salad for a balanced meal.

Note: Those with lactose intolerance or egg allergies should modify accordingly. Also, individuals monitoring sodium intake should use low-sodium cheese and limit added salt.

FAQ

Can I make this quiche ahead of time?
Yes! Assemble and refrigerate unbaked quiche overnight, or fully bake and reheat in a 325°F oven for 15–20 minutes. It also freezes well for up to 3 months.

Why is my quiche watery?
This usually happens if spinach wasn’t squeezed dry or if the quiche wasn’t baked long enough. Always drain vegetables thoroughly and ensure the center is set before removing from oven.

Can I skip the crust?
Absolutely. Grease the pie dish well and pour the filling directly in for a lower-carb, crustless version. Reduce baking time by 5–10 minutes.

How do I store leftovers?
Keep in an airtight container in the refrigerator for up to 4 days. Reheat individual slices in the microwave or oven.

Can I use frozen spinach?
Yes, but thaw completely and squeeze out as much liquid as possible. About 10 oz frozen spinach (cooked and drained) equals roughly 4 cups fresh.

What’s the best cheese for this quiche?
Feta offers a bold, tangy contrast, while Gruyère melts smoothly and adds nuttiness. A blend of both is excellent.

Is quiche safe to eat cold?
Yes, many people enjoy quiche chilled. It’s perfect for picnics, lunchboxes, or quick snacks.
