Easy Bacon Spinach Mushroom Cheese Quiche Recipe
Some brunch dishes feel elevated, satisfying and quietly impressive without complicated steps. This Bacon, Onion, Spinach, Mushroom, and Pepper Jack Cheese Quiche is one of my most reliable go-to recipes when I’m hosting. It’s rich, savory, and layered with flavor, yet simple enough to prepare without stress. Moreover, it keeps the best possible company at brunch — a tray of bacon, spinach and cheese egg muffins and my apple cinnamon overnight oats cover everyone at the table.
As someone who entertains often, I’ve come to appreciate recipes that deliver both ease and impact. This quiche does exactly that. It’s the kind of dish that fills the kitchen with warmth, invites guests to linger, and works beautifully across everything from casual brunches to more intentional gatherings, whether I am pouring my champagne brunch punch or building a full champagne bar.
If you love recipes that feel thoughtful but approachable, this is one you’ll come back to again and again. In particular, pour something lovely beside it: holiday mimosa recipes for a crowd, or a single spiked iced coffee on a slow morning.
What Is Bacon Spinach Mushroom Quiche?
Bacon, Onion, Spinach, Mushroom, and Pepper Jack Cheese Quiche is a savory, oven-baked egg custard dish layered with smoky, creamy, and slightly spicy flavors—all set inside a buttery pie crust. Equally important, that same pastry instinct runs through my tomato basil mozzarella puff pastry and these rhubarb puff pastries with mascarpone cream.
At its core, quiche is a classic dish made from eggs and dairy, gently baked until it forms a soft, sliceable custard. What makes this particular version stand out is the combination of ingredients that create both balance and depth. To illustrate, it is the savory sibling of my spinach and bacon quiche — same custard logic, different personality.
Here’s how I think about it:
- Bacon adds a rich, smoky saltiness that anchors the dish
- Onions bring a subtle sweetness once cooked
- Spinach adds freshness and lightness
- Mushrooms give it an earthy, savory depth
- Pepper Jack cheese introduces a creamy texture with a gentle kick of heat
All of this is folded into a mixture of eggs and milk, then baked slowly so the texture stays smooth and custardy—not dense or dry.
The result is a dish that feels comforting yet elevated. It’s hearty enough to stand on its own, but still light enough to serve at brunch or alongside a simple salad. Given that, I will serve it with my winter salad in cold months and one of these eight salads the rest of the year.
I often describe quiche like this:
it’s where simplicity meets intention. You’re taking everyday ingredients and transforming them into something cohesive, balanced, and quietly impressive. What’s more, a spring charcuterie board beside it turns brunch into something people photograph before they eat.
This version, in particular, is ideal when you want something that feels a little more special than a typical breakfast—but still easy to prepare and serve. On the other hand, when the morning calls for something sweet instead, my orange-scented olive oil bundt cake and cinnamon rolls for cozy mornings do the job.
Bacon Spinach Mushroom Quiche Ingredients (With Purpose & Flavor Notes)
Each ingredient in this quiche plays a role—not just in flavor, but in texture and structure.
Bacon
Adds a rich, savory depth and slight crispness that anchors the entire dish.
Eggs
The foundation of the custard—responsible for structure and creaminess.
Whole Milk
Creates a smooth, silky texture. I always use whole milk for richness.
Salt & Garlic Salt
Enhances overall flavor while adding a subtle savory note.
Black Pepper
Adds warmth and balance.
Fresh Spinach
Brings freshness and a slight bitterness that balances the richness.
Mushrooms
Earthy and grounding, adding depth and texture.
Onion
Aromatic and slightly sweet once sautéed.
Pepper Jack Cheese
Creamy with a gentle spice that elevates the flavor profile.
Mild Cheddar Cheese
Adds sharpness and richness.
9-inch Deep Dish Pie Crust
Provides structure and a buttery contrast to the custard filling.
Pro Tips For the Best Quiche
These are the small, thoughtful details I rely on to make sure this quiche turns out consistently creamy, balanced, and beautifully finished:
- Cook out excess moisture
Sauté vegetables until all liquid is gone to avoid a watery filling. - Balance eggs and dairy
The right ratio ensures a creamy, custardy texture—not rubbery or dense. - Bake low and steady
Lower heat helps the custard set gently without scrambling the eggs. - Let it rest before slicing
Resting for 20–25 minutes allows the quiche to fully set and hold its shape. - Use a deep-dish crust
This keeps the filling contained and gives you a more substantial, even bake.

Salad Spinner
Wash the spinach and spin it bone-dry first; less water in the greens means a custard that sets instead of weeping.
Cast Iron Skillet
One pan crisps the bacon, then sautés the onions, mushrooms and spinach right in those savory drippings.
XL Cheese Grater
Freshly grated pepper jack and cheddar melt far more smoothly into the custard than bagged shreds.
Glass Measuring Cups
The 2-cup measure is just right for the milk, and an exact pour keeps the custard silky rather than rubbery.
Glass Mixing Bowls
The largest bowl gives you room to whisk the custard and fold in every filling without a splash.
Stainless Steel Whisk Set
Whisk the eggs, milk and seasonings until completely smooth, so no streaks of egg white bake into the slice.
Deep Dish Pie Pan
A 9-inch ceramic deep dish holds every drop of filling and goes straight from the oven to the brunch table.
Pie Crust Shield
If the crust edge browns before the center sets, slip this on for the last stretch of baking.
Wire Cooling Racks
Air all the way around the pan helps the quiche set evenly during its 25-minute rest.
Pie Server
A sharp, wedge-shaped server lifts out clean slices without the filling sliding off.
Glass Cake Stand with Dome
Present the whole quiche on a pedestal, and the dome keeps it covered until your guests sit down.
Airtight Storage Containers
Leftover slices keep for three to four days in the fridge, ready to reheat gently in the oven.
How To Make Bacon Spinach Mushroom Quiche
1
Prepare the base
Cook the bacon until crisp, then sauté the onions, mushrooms, and spinach until softened and moisture is removed.
2
Make the custard
Whisk together eggs, milk, and seasonings until smooth. Stir in the cooked fillings and most of the cheese.
3
Assemble
Pour the mixture into the pie crust and top with the remaining cheese.
4
Bake and rest
Preheat the oven to 400°F, then reduce it to 350°F when the quiche goes in. Bake for about 35 to 40 minutes, until just set and lightly golden, then let it rest for at least 25 minutes before slicing.
Bacon, Onion, Spinach, Mushroom and Pepper Jack Cheese Quiche
Ingredients
- 6 slices bacon
- 4 large eggs beaten
- 1 ½ cup whole milk
- ½ tsp salt
- ½ tsp garlic salt
- ½ tsp black pepper
- 2 cups fresh spinach chopped
- 2 cups mushrooms chopped
- ½ cup onion chopped
- 1 cup shredded pepper jack cheese
- 1 cup shredded mild cheddar cheese
- 1 9-inch deep dish pie crust
Instructions
- Preheat your oven to 400°F (200°C).
- Cook the bacon in a skillet over medium heat until crisp. Drain, crumble, and set aside.
- In the same pan, sauté the onions, mushrooms, and spinach until softened and excess moisture has evaporated. This step is essential—too much moisture will affect the custard.

- Pour the mixture into the pie crust and top with the remaining cheese.
- Reduce the oven temperature to 350°F and bake for about 35–40 minutes, or until the center is just set and the top is lightly golden.
- Let the quiche rest for at least 25 minutes before slicing. This step is non-negotiable—it allows the custard to fully set.

Bacon Spinach Mushroom Quiche FAQs
Why is my quiche watery?
This usually comes from excess moisture in vegetables or too much milk. Always sauté and measure carefully.
Can I make this ahead of time?
Yes—and I often do. Bake it the day before and reheat gently before serving.
How do I know when it’s done?
The center should be just set with a slight jiggle—not liquid. It will firm up as it rests.
Can I use cream instead of milk?
You can, but it will be richer. I prefer a balance of milk for a lighter texture.
Do I need to pre-bake the crust?
This recipe pours the filling into an unbaked deep-dish crust. If you like a crisper bottom, you can pre-bake the crust for about 10 minutes first.
Can I use frozen spinach?
Yes. Thaw it completely and squeeze out as much liquid as possible before adding it to the pan.
Final Thoughts
This Bacon, Onion, Spinach, Mushroom, and Pepper Jack Cheese Quiche is one of those recipes that proves simple can still feel elevated. It’s comforting, versatile, and quietly impressive—everything I look for when I’m hosting.
