Breakfast & Brunch
This bacon mushroom spinach cheese quiche delivers the perfect balance of smoky, savory, and creamy flavors in every bite—starting with a flaky crust that shatters when cut. The secret to success lies in pre-cooking the fillings to prevent a soggy bottom, while the cheese melts into golden perfection.
I've perfected this recipe over years of weekend brunch experiments, ensuring the bacon stays crispy and the spinach maintains its vibrant color.
What sets this quiche apart is the layered approach: crispy bacon forms the flavor base, mushrooms add earthy depth, and spinach brings freshness, all bound together by a rich egg custard. The crust can be store-bought for convenience or homemade for that extra-crispy edge—both methods yield impressive results.
Baking at the right temperature ensures the center stays just set while the edges achieve that signature golden-brown finish.
By the time it emerges from the oven, you'll have a quiche with a lattice of textures—flaky crust, tender bacon, wilted spinach, and melted cheese that pulls in long strands.
The aroma alone will have everyone gathering around the table, and each slice delivers that satisfying combination of smoky, cheesy, and herby flavors. This is the kind of brunch dish that becomes a household favorite in just one serving.
Perfect for weekend gatherings, meal prep, or a special breakfast treat, this quiche scales easily for crowds while maintaining its restaurant-quality appeal. The filling can be prepped ahead, making it ideal for stress-free mornings. Let's get started on creating your perfect quiche.
Ingredients for bacon mushroom spinach cheese quiche
Six crispy, cheesy, smoky layers—all you need for a brunch showstopper.

The bacon is non-negotiable here—thick-cut stays crispy longer. Costco or Trader Joe's always have the best quality, but any smoked or hickory-flavored bacon works. For mushrooms, white or cremini slice fastest—avoid the pre-sliced kind, it gets mushy. Spinach? Baby spinach is ideal, but regular leaves work if you chop them small. The cheese? Sharp cheddar melts best, but Gruyère or Swiss add great flavor too. Freshly grated is key—pre-shredded gets clumpy and won't melt right.
No thick-cut bacon? Regular bacon chopped into small pieces works in a pinch. Mushrooms too watery? Pat them dry with a paper towel before cooking. Short on spinach? Kale or Swiss chard at half the amount works well. The custard can be made ahead—just keep it refrigerated and whisk well before pouring. For the crust, homemade is worth it if you're feeling fancy, but store-bought saves time. The secret? Chill the crust for 15 minutes before baking to keep it flaky.
This quiche reheats like a dream—350°F for 10-15 minutes until warm through. Keeps 4-5 days in the fridge, 3 months frozen. I always make a double batch—one for brunch, one for lunches. The crust stays crispy if you store it in an airtight container. For extra crispiness, broil for 2 minutes at the end of baking. Trust me on this—the first slice is always the best.
Why You'll Love This Recipe
- No-Fuss Assembly: I swear, this quiche comes together faster than a microwave dinner. Crumble that pre-made crust, fry the bacon in the same pan you’ll sauté the mushrooms—no extra dishes—and just fold in the spinach and cheese. Honestly, my lazy Sunday mornings have never been this satisfying.
- Crispy-Creamy Magic: That first bite? The buttery crust gives way to a creamy custard, while the bacon stays perfectly crispy—not soggy. The sharp cheddar melts into little pockets of gooey goodness, and the mushrooms add this earthy depth that makes it taste like a restaurant dish. (Yes, even on a Tuesday night.)
- Leftovers That Don’t Suffer: Between us, most quiches turn into a sad, rubbery mess when reheated. Not this one. The bacon stays crisp, the cheese holds its shape, and the spinach doesn’t wilt into a swamp. I’ve packed this for lunches all week—no one’s complained yet.
- Budget Breakfast for Crowds: You’re getting all the flavors of a fancy brunch for pennies. Thick-cut bacon adds richness without breaking the bank, mushrooms bulk it up, and cheddar stretches further than some fancy cheeses. Feed four for less than takeout, and still have leftovers. My wallet thanks me every time.
Step-by-step instructions for bacon mushroom spinach cheese quiche
Here's how to build a quiche with layers of crispy bacon, tender mushrooms, wilted spinach, and a perfectly set custard.
Prepare the Crust for Maximum Flakiness
Preheat your oven to 375°F. Remove the store-bought pie crust from its packaging and gently unfold it onto a clean work surface. I like to press it into a 9-inch pie dish using my fingers, working from the center outward. This ensures an even thickness and helps prevent cracking during baking.
Here's the secret to flaky perfection: prick the bottom of the crust all over with a fork, about ¼-inch apart. This creates tiny vents that allow steam to escape, preventing a soggy bottom. Line the crust with a single layer of parchment paper, then fill it with pie weights or dried beans. Bake for 12-15 minutes until the edges are light golden brown. Remove the weights and return the crust to the oven for another 2-3 minutes to crisp up any soft spots.
Cook the Bacon and Sauté the Vegetables
While the crust is baking, place the 0.5 lb thick-cut bacon in a large skillet over medium heat. Cook for 8-10 minutes, flipping occasionally, until the bacon is deep golden brown and crispy. Use a slotted spoon to transfer the bacon to paper towels to drain excess fat, leaving about 2 tablespoons of rendered fat in the pan.
In the same skillet (no need to wipe it clean—the bacon fat is flavor gold), add the 1 cup sliced white mushrooms and cook for 4-5 minutes until they release their moisture and begin to brown. Add the 4 cups baby spinach and cook for another 2 minutes until just wilted. Sprinkle with 0.5 tsp garlic powder and 0.5 tsp onion powder, stirring to coat evenly. Remove from heat and set aside.
Make the Rich Custard Filling
In a large bowl, whisk together the 4 whole large eggs, 0.5 cup heavy cream, 0.5 cup milk, 0.25 cup all-purpose flour, 0.5 tsp salt, and 0.25 tsp black pepper until completely smooth. The mixture should be pale yellow and slightly thickened. Here's the thing—this custard needs to be perfectly blended so it sets smoothly without lumps.
Gently fold in the cooked bacon, mushroom-spinach mixture, and 1.5 cups shredded sharp cheddar cheese using a spatula. You want to distribute everything evenly without overmixing. The cheese should be melted and well incorporated, but don't worry if it looks slightly streaky—it'll blend beautifully during baking.
Assemble and Bake to Golden Perfection
Carefully pour the custard mixture into the pre-baked crust. The filling should come about ½-inch below the crust's edge—this prevents overflow. Dot the top with the remaining 1 tablespoon butter, cut into small pieces, for extra richness.
Bake for 35-40 minutes until the custard is set but still slightly jiggly in the center (it'll continue firming up as it cools). The edges should be deep golden brown, and the top should have a beautiful, slightly puffed appearance. If the crust starts to darken too quickly, loosely cover it with aluminum foil.
Rest and Serve with Confidence
Remove the quiche from the oven and let it cool for 10-15 minutes before slicing. This resting period allows the custard to fully set and the flavors to meld together. You'll notice the quiche will puff slightly as it cools—this is a good sign!
Use a sharp knife to cut into 6 equal wedges, wiping the blade between cuts to ensure clean slices. Serve warm with a simple side salad or crusty bread. Each bite should deliver a perfect balance of crispy bacon, earthy mushrooms, tender spinach, and that rich, creamy custard—all wrapped in a flaky, buttery crust that's the star of the show.
Pro Tips For Making Bacon Mushroom Spinach Cheese Quiche
- Crisp the Bacon First: Cook the thick-cut bacon until it’s slightly underdone—just past the bendy stage, not fully crisp. That extra fat renders out into the filling, making the quiche richer without needing extra oil. (Yes, even if you’re impatient like me.)
- Sauté Mushrooms Until Dry: Push those mushrooms around the pan until they release all their moisture and develop a golden crust. Wet mushrooms will turn your filling into soup, and nobody wants a soggy quiche. A dry pan and 5-7 minutes of attention make the difference.
- Prevent Spinach from Curdling: Toss the baby spinach with a pinch of salt and let it wilt completely before adding it to the quiche. Cold, fresh spinach stays stubborn—warm it up first, or you’ll end up with a sad, watery mess. (Your future self will thank you.)
- Bake Blind, Then Uncover: Cover the quiche with foil for the first 20 minutes—this keeps the crust from burning while the filling sets. Then, uncover and finish under the broiler for 2-3 minutes to get that golden, bubbly cheese top. (No, the crust won’t collapse. I promise.)
Essential equipment for great bacon mushroom spinach cheese quiche
Pie Dish Must-Haves
Start with a 9-inch glass or ceramic pie dish—it conducts heat evenly and prevents soggy bottoms. I recommend Corelle stoneware for its durability and even baking.
If you prefer metal, a heavy-gauge aluminum dish like Wilton works well too. Avoid dark-colored dishes—they absorb heat unevenly and can overcook the crust edges. 🥧
Crust Prep Tools
For store-bought crusts, a rolling pin helps smooth out wrinkles before pressing into the dish. If making a homemade crust, a food processor is essential for blending butter and flour quickly.
I also keep pie weights or dried beans on hand for pre-baking crusts—Wilton pie weights are my go-to for even support. A sharp knife (like Wüsthof) comes in handy for trimming excess crust edges neatly.
Skillet Essentials
Cooking bacon and mushrooms requires a 10-12-inch cast-iron skillet—Lodge is my favorite for its heat retention. For non-stick convenience, a well-seasoned carbon steel pan like Mauviel works beautifully. A slotted spoon (preferably stainless steel) helps drain excess fat while keeping crispy bacon intact.
Keep a paper towel-lined plate nearby to catch drippings—this prevents messes and makes cleanup easier.
Mixing & Measuring
Whisking the custard requires a balloon whisk or silicon spatula—I prefer OXO Good Grips for its durability. Measure liquids with a liquid measuring cup (like Pyrex) and dry ingredients with a stainless steel measuring cup set.
A kitchen scale (such as Escali) ensures precise cheese measurements for consistent melting. For folding in delicate spinach, a flexible silicone spatula prevents overmixing while keeping ingredients intact. 🥛
Baking & Resting
An oven thermometer (like Thermoworks) is non-negotiable—many ovens run hot or cold. A lightweight aluminum foil sheet helps shield crusts from over-browning. For resting, I use a wire cooling rack placed over a baking sheet to catch any drips.
A sharp chef's knife (like Victorinox) with a pie cutter attachment makes slicing clean wedges effortless. Keep a small bowl of cold water nearby to wipe the knife between cuts—this prevents crumbs from sticking.

Frequently asked questions
Can I make this quiche ahead of time?
Assemble the quiche up to 24 hours ahead and refrigerate it uncovered. Bake it straight from the fridge (add 5-10 minutes to baking time) for even cooking. For freezing, bake the quiche first, then cool completely, wrap tightly in plastic wrap and foil, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
How do I prevent a soggy crust?
Pre-baking the crust is key! Blind-bake it with pie weights for 12-15 minutes before adding filling. For extra insurance, sprinkle a thin layer of shredded cheese or crushed cornflakes on the pre-baked crust before pouring in the custard. This creates a moisture barrier while adding flavor.
Can I substitute any ingredients?
Certainly! Swap mushrooms for sun-dried tomatoes or bell peppers for a different flavor profile. Use feta or goat cheese instead of cheddar for tangy notes, or add caramelized onions for extra sweetness. For bacon lovers, try turkey bacon or pancetta—both work beautifully. Just maintain the 1:1 ratio.
Why is my custard still runny after baking?
This usually happens from underbaking or too much liquid. Increase baking time by 5-10 minutes or reduce heavy cream by 2 tablespoons next time. Also ensure your oven is at 350°F (use an oven thermometer) and the custard isn't too hot when poured into the crust—let it sit for 10 minutes after whisking.
How should I slice and serve this quiche?
Wait 10-15 minutes after baking to let it set completely. Use a sharp knife and wipe it between slices to prevent crumbs. Serve warm with a simple arugula salad, crusty bread, or roasted potatoes. For parties, cut into 8 smaller wedges—they're easier to serve and look more elegant!
