Breakfast & Brunch
This bacon mushroom spinach cheese quiche delivers the perfect balance of smoky, savory, and creamy flavors in every bite. The secret lies in a crisp, flaky crust that holds its shape while the rich egg custard transforms into a velvety center.
I've perfected this recipe through countless test batches, ensuring the filling stays moist while the crust achieves that coveted golden-brown finish.
The magic happens in the layering: crispy bacon adds depth, sautéed mushrooms bring earthy richness, and wilted spinach keeps it vibrant. A blend of sharp cheddar and creamy Gruyère ensures the cheese melts into perfect, stretchy strands.
For the crust, I offer both a classic homemade option and a quick store-bought shortcut—because even the best quiche deserves flexibility.
What you'll end up with is a quiche that's sturdy enough to slice cleanly yet tender enough to melt in your mouth.
The aroma of baking bacon and mushrooms will fill your kitchen, while the golden crust and creamy filling make it ideal for brunch, lunch, or even a hearty dinner. This recipe combines traditional quiche techniques with modern conveniences for foolproof results.
Whether you're serving it at a weekend brunch or packing leftovers for the week, this quiche delivers restaurant-quality flavor with minimal effort. The key is patience—letting the custard set properly ensures that first bite is as perfect as the last. Let's get started on creating your ideal quiche.
Ingredients for bacon mushroom spinach cheese quiche
Six layers of flavor—crispy crust, smoky bacon, earthy mushrooms, and melty cheese—all baked into one perfect quiche.
| Ingredient | Amount | Notes |
|---|---|---|
| Bacon 🥓 | 6 oz | Thick-cut preferred, chopped small |
| Mushrooms 🍄 | 1 cup | Cremini or white, sliced thin |
| Fresh Spinach 🌿 | 2 cups | Baby spinach, roughly chopped |
| Sharp Cheddar Cheese 🧀 | 1 cup | Shredded, aged 6 months minimum |
| Gruyère Cheese 🧀 | ½ cup | Shredded, for creamy texture |
| Large Eggs 🥚 | 4 whole | Room temperature for even baking |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Whole Milk 🥛 | ¼ cup | Warmed slightly for smooth custard |
| All-Purpose Flour 🌾 | 1 ½ cups | For homemade crust |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for crust |
| Ice Water 💧 | ¼ cup | For pie crust consistency |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for warmth |
| Garlic Powder 🧄 | ½ tsp | For subtle depth |
| Onion Powder 🧅 | ½ tsp | Enhances savory notes |
The bacon is non-negotiable here—thick-cut gives the best texture, and Trader Joe's or Costco are my go-tos for quality. Cook it until crispy, then drain on paper towels to keep the filling dry. Mushrooms should be sliced paper-thin for even cooking—cremini has the best flavor, but white works too. For the spinach, baby leaves are ideal (no stems to remove), but regular spinach works if you chop it finely. The cheeses? Sharp cheddar for tang, Gruyère for creaminess—both should be freshly shredded (pre-shredded gets gummy).
No thick-cut bacon? Regular bacon at half the cook time works in a pinch. Mushroom lovers can add an extra cup—just cook it all in one batch. Swapping cheddar? Gouda or Monterey Jack are great alternatives. For the crust, store-bought works (like Pepperidge Farm), but homemade gives that flaky perfection. The eggs should be room temperature—cold eggs make the custard lumpy. And if you're short on time, pre-made pie crust cuts prep time in half without sacrificing flavor.
This quiche tastes even better the next day—3-4 days in the fridge, covered tightly. For leftovers, reheat in a 350°F oven for 15 minutes with foil over the top. Freezes beautifully for up to 2 months: wrap tightly in plastic, then foil. Slice before reheating for clean portions. The crust stays crispy, the filling stays creamy—perfect for meal prep. And if you're serving it warm? Broil for 2-3 minutes to get that golden finish.

Step-by-step instructions for bacon mushroom spinach cheese quiche
Here's how to build a quiche with layers of smoky bacon, creamy Gruyère, and tender spinach—all topped with a perfectly flaky crust.
Make the Homemade Crust
In a large bowl, combine the 1.5 cups all-purpose flour, 1 tsp salt, 0.5 tsp black pepper, 0.5 tsp garlic powder, and 0.5 tsp onion powder. Cut in the 0.5 cup unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces.
Gradually add the 0.25 cup ice water, 1 tablespoon at a time, mixing gently with a fork until the dough just comes together. It should hold when pressed but not be sticky. Turn the dough onto a lightly floured surface and knead briefly until smooth. Wrap in plastic and chill for 30 minutes—this resting time is crucial for a flaky crust.
Cook the Bacon and Sauté Vegetables
In a 10-inch oven-safe skillet, cook the 6 oz bacon over medium heat until crispy, about 8-10 minutes. Remove the bacon with a slotted spoon and set aside, leaving the fat in the skillet. Add the 1 cup sliced mushrooms and cook for 4-5 minutes until golden and tender.
Stir in the 2 cups chopped spinach and cook just until wilted, about 2 minutes. Remove from heat and set aside with the bacon. The skillet should still have some bacon fat—this will help create a rich, flavorful base for your quiche filling.
Assemble the Quiche Filling
Preheat your oven to 375°F. Roll out the chilled dough on a lightly floured surface to fit your skillet, about 1/8-inch thick. Transfer the dough to the skillet and press it gently into the bottom and up the sides. Trim any excess dough hanging over the edge.
In a large bowl, whisk together the 4 whole large eggs, 0.5 cup heavy cream, and 0.25 cup whole milk until well combined. Stir in the 1 cup shredded sharp cheddar cheese and 0.5 cup shredded Gruyère cheese until fully melted and smooth. Season with an additional 0.25 tsp salt if needed.
Layer and Bake to Golden Perfection
Spread the cooked bacon and mushrooms evenly over the crust. Pour the egg mixture over the top, spreading it to the edges. The filling should be about 1/2-inch thick—this ensures a creamy center without being too heavy.
Bake for 35-40 minutes until the crust is golden brown and the filling is set but still slightly jiggly in the center. If the edges brown too quickly, cover them loosely with aluminum foil. The quiche is done when the center reaches 160°F on an instant-read thermometer.
Rest and Serve
Remove the quiche from the oven and let it rest for 10 minutes before slicing. This resting time allows the filling to set completely and prevents it from running when you cut into it. The crust should be crisp, the filling creamy, and every bite packed with smoky bacon, earthy mushrooms, and melty cheese.
Serve warm with a simple side salad or crusty bread. Leftovers keep well in the refrigerator for 3-4 days—just reheat in the oven at 350°F for 10-15 minutes to restore that perfect texture.
Pro Tips For Making Bacon Mushroom Spinach Cheese Quiche
- CRISP THE BACON FIRST: I learned this the hard way—cooking bacon in the quiche pan leaves a greasy mess that soaks into the crust. Render the bacon on a separate sheet pan, then drain it well on paper towels before crumbling. The extra effort keeps your crust from turning soggy, and the bacon stays crispier longer.
- SAUTÉ MUSHROOMS UNTIL DRY: Wet mushrooms add moisture that turns your filling into a sad, watery sludge. Cook them until every last drop of liquid has evaporated—about 8-10 minutes on medium-high. If they’re still glossy, pat them dry with a clean towel first. Trust me, your quiche’s texture depends on this.
- SALT THE SPINACH: Fresh spinach wilts fast but also releases bitter juices. Toss it with a pinch of salt and let it sit for 5 minutes before adding it to the filling. This draws out excess water and mellows the flavor—no one wants a quiche that tastes like a sad salad.
- BAKE COLD, NOT ROOM TEMP: A warm egg mixture sets unevenly and can cause cracks or a gummy center. Whisk your eggs and dairy, then pop the whole bowl in the fridge for 15 minutes before pouring. Cold ingredients bake more evenly, and your quiche won’t end up with a runny middle or a crust that’s still doughy. (Yes, even if you’re impatient like me.)

Frequently asked questions
Can I make this quiche without a homemade crust?
A store-bought pie crust works perfectly—just follow the package instructions to press it into your skillet. For extra flakiness, blind-bake it for 5-7 minutes at 375°F before adding the filling. Pepperidge Farm or Pillsbury crusts are my top recommendations for this recipe.
How do I prevent a soggy crust?
Prevent sogginess by pre-baking the crust for 5 minutes before adding the filling. Another trick is to sprinkle a thin layer of crushed cornflakes or almond flour between the crust and filling. This creates a barrier that keeps the crust crisp while the filling stays creamy.
What’s the best way to reheat leftovers?
Reheat slices in a 350°F oven for 10-15 minutes with foil covering the top to retain moisture. For microwave reheating, cover with a damp paper towel and heat for 30-45 seconds—this keeps the crust from drying out. Avoid reheating at high power to prevent rubbery eggs.
Can I use frozen spinach instead of fresh?
Yes! Thaw and drain 10 oz frozen spinach thoroughly, then squeeze out excess water. Cook it with the mushrooms until fully wilted. Frozen spinach works well but loses some texture—fresh is ideal for the best bite. If using frozen, reduce the spinach to 1.5 cups to match the recipe’s moisture balance.
Why did my quiche turn out dry?
Overbaking is the most common cause. The filling is done when it’s just set but still slightly jiggly in the center (160°F internally). If you prefer a firmer texture, bake at 350°F instead of 375°F—this gives more time for the custard to set without drying. Also, ensure your eggs and dairy are at room temperature for even baking.
