🥘 Introduction: The Elegant Simplicity of Spinach and Mushroom Quiche

The Story Behind Quiche: From French Roots to Brunch Favorite

Quiche may feel like a modern brunch trend, but its story begins in medieval Europe. The dish we know today as quiche actually hails from the medieval kingdom of Lothringen, now known as Lorraine in northeastern France. There, cooks created the iconic Quiche Lorraine, a savory tart made with eggs, cream, and bits of bacon nestled into a buttery crust.

Over the centuries, the concept evolved and spread throughout Europe, eventually reaching the United States and gaining traction as a sophisticated, yet simple meal option. In the 1970s, during the natural foods movement, vegetarian adaptations like spinach and mushroom quiche surged in popularity. The addition of vegetables not only lightened the dish but made it accessible for vegetarians and health-conscious eaters alike.

Whether you prefer it with cheese or crustless for a low-carb breakfast, spinach and mushroom quiche fits seamlessly into almost any menu — from a casual Sunday brunch to a weeknight meal prep.

Here are 10 regions where this quiche is especially popular:

🔧 What You’ll Need: Tools & Prep Tips for a Flawless Quiche

Essential Equipment to Get Started

Making a silky, golden spinach and mushroom quiche is easier when you’ve got the right kitchen tools on hand. You don’t need a chef’s kitchen — just a few dependable essentials:

9-inch pie pan or tart dish – Perfect size for standard quiche recipes
Mixing bowl – For whisking eggs and dairy together
Whisk or electric hand mixer – Ensures a smooth custard blend
Saute pan – To soften and caramelize vegetables
Oven – Preheated to 375°F for blind baking and final cook

Helpful Add-Ons and Time-Saving Prep Tips

If you’re aiming for an ultra-smooth crust or professional presentation, these tools and tricks make a difference:

Pie weights or dried beans – Great for blind baking the crust to avoid sogginess
Pastry brush – Helps seal the crust or add egg wash for golden color
Parchment paper – Prevents sticking and makes crust cleanup easy
Food processor – Speeds up chopping and ensures uniform veggie pieces

📝 Prep Tips for Quiche Success:

Pre-cook your spinach and mushrooms to reduce water content — excess moisture makes the custard runny.
Let your eggs sit at room temperature for 15–20 minutes before mixing to help them incorporate smoothly.
Thoroughly drain or press any frozen spinach if using, to maintain quiche texture.

👩‍🍳 Instructions: How to Make a Spinach and Mushroom Quiche from Scratch

Step-by-Step Cooking Guide

This easy spinach mushroom quiche comes together with just a few basic techniques. Follow these steps for perfect results every time:

Prep the Crust
- Preheat your oven to 375°F (190°C).
- If using a pie crust, gently press it into a 9-inch pie dish.
- Blind bake the crust by lining it with parchment paper and filling with pie weights or dried beans.
- Bake for 10 minutes, remove weights, then let the crust cool while you prep the filling.
Sauté the Vegetables
- Heat 1 tablespoon olive oil in a pan over medium heat.
- Add diced onion and cook until translucent, about 3 minutes.
- Stir in mushrooms and cook until softened and lightly browned, about 5 more minutes.
- Add chopped spinach and cook just until wilted. Remove from heat and let cool slightly.
Whisk the Custard
- In a medium bowl, whisk together 4 eggs, 1 cup milk or half & half, salt, pepper, and a pinch of nutmeg if using.
- Stir in 1 cup shredded cheese (cheddar, Swiss, or feta all work beautifully).
Assemble the Quiche
- Spread the sautéed veggies evenly across the pre-baked crust.
- Pour the egg mixture over the vegetables, using a spoon to ensure even distribution.
Bake the Quiche
- Bake at 375°F for 35–40 minutes, or until the center is just set and the top is lightly golden.
- If the edges of the crust brown too quickly, cover them with foil halfway through baking.
Cool & Slice
- Let the quiche rest for 10 minutes before slicing to allow the custard to set.
- Serve warm, at room temperature, or even chilled — it’s delicious any way you slice it.

Pro Tips for Quiche Perfection

Don’t overfill the crust — you may have a bit of custard left depending on pan depth.
Insert a knife near the center to check doneness — it should come out mostly clean.
For a firmer texture, bake on the lower oven rack to crisp the crust base. Planning a Brunch Spread? Add These Cheddar Scallion Cornbread Muffins

❓ FAQs: Your Spinach and Mushroom Quiche Questions Answered

Can you freeze spinach and mushroom quiche?

Absolutely! This dish is perfect for freezing. For best results, slice the quiche into portions, wrap each slice tightly in plastic wrap and foil, then freeze for up to 3 months. To reheat, bake at 350°F straight from the freezer for about 20–25 minutes, or until warmed through.

This makes it a go-to for make-ahead spinach mushroom quiche fans looking to stock their freezer with nourishing meals.

Is quiche healthy for breakfast?

Yes — especially when it’s made with vegetables and lighter dairy options. Eggs provide a strong source of protein, and spinach adds iron, fiber, and vitamins A and C. For a healthier version, try a crustless spinach mushroom quiche with low-fat cheese and skim milk.

This is a great alternative to sugary cereals or pastries and fits well into most meal plans, including vegetarian and low-carb.

Can I use fresh spinach instead of frozen?

Definitely. In fact, many prefer it for a fresher taste and firmer texture. Just sauté fresh spinach until wilted, and be sure to remove any excess moisture before mixing it into the filling. If using frozen spinach, thaw it completely and squeeze out all the liquid with a paper towel or cheesecloth.

How do I reheat leftover quiche?

To retain the best texture, reheat slices in the oven at 325°F for 10–15 minutes. This keeps the crust crispy and the filling soft. If you’re short on time, use the microwave, but place a damp paper towel over the slice to avoid drying it out. For a crispier edge, a toaster oven works wonders.
