Ingredients for bacon cheese and onion quiche
This quiche recipe balances rich crust, smoky bacon, and caramelized onions for brunch perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crust |
| All-Purpose Flour 🌾 | 2 ½ cups | Plus 2 tbsp for rolling |
| Ice Cubes ❄️ | ½ cup | For chilled dough |
| Large Eggs 🥚 | 3 whole | Room temperature |
| Heavy Cream 🥛 | 1 cup | Full-fat preferred |
| Whole Milk 🥛 | ½ cup | Warmed slightly |
| Sharp White Cheddar Cheese 🧀 | 1 ½ cups | Shredded, block preferred |
| Cooked Bacon 🥓 | 8 oz | Crumbled, thick-cut |
| Yellow Onions 🧅 | 1 ½ cups | Diced, caramelized |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Nutmeg 🌿 | ¼ tsp | Freshly grated |
The crust starts with cold butter—cut it into small cubes and pulse with flour in a food processor for maximum flakiness. King Arthur or Gold Medal flour yields the best texture, but any all-purpose works. Chill the dough between rolls to prevent shrinking. For extra crispiness, blind-bake the crust for 15 minutes before adding filling. If using a gluten-free crust, follow package instructions for pre-baking times—some require 20+ minutes to achieve the same stability.
Caramelizing onions transforms them from sharp to sweet—yellow onions work best for their balance. Cook them low and slow until deep golden brown, about 30 minutes. No patience? Use 1 cup pre-caramelized onions from the grocery store (check the refrigerated section). The bacon should be thick-cut and cooked until crispy—drain on paper towels to remove excess fat. For a dairy-free option, substitute sharp white cheddar with nutritional yeast (though texture will differ). The custard relies on room-temperature eggs to blend smoothly—crack them into a bowl first to check for freshness.
Assemble the quiche just before baking to prevent a soggy crust. Pre-bake the crust thoroughly—this is non-negotiable for crispy edges. The custard should set in 35-40 minutes at 375°F, but use a toothpick test: it should come out clean. Leftovers keep 4 days in the fridge, though this quiche reheats better than most—10 minutes at 350°F restores crispiness. For make-ahead prep, assemble the quiche (without baking) and refrigerate overnight, then bake straight from the fridge (add 5-10 minutes to cooking time).

Step-by-step instructions for bacon cheese and onion quiche
Master the perfect balance of flaky crust, rich custard, and smoky-sweet filling.
Prepare the Classic Pâte Brisée Dough
Cut the 1 cup unsalted butter into ½-inch cubes and place in the freezer for 10 minutes to firm up. In a food processor, pulse together the 2.5 cups all-purpose flour and 1.5 teaspoons salt until combined. Add the chilled butter cubes and process until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.
Transfer the mixture to a bowl, sprinkle over the 0.5 cup ice cubes, and toss gently with a fork until the ice melts and the dough begins to clump. Avoid overworking—just combine until it holds together when pressed. Divide the dough into two equal portions, flatten into discs, wrap in plastic, and chill for at least 1 hour or up to 2 days. This resting time is crucial for developing flavor and preventing shrinking during baking.
Assemble the Crust and Filling
Preheat your oven to 375°F. Roll out one dough disc on a lightly floured surface to fit a 9-inch pie dish, about ⅛-inch thick. Transfer to the dish, trim excess dough, and prick the bottom all over with a fork. Line the crust with parchment paper, fill with pie weights or dried beans, and blind-bake for 15 minutes. Remove the weights and bake an additional 5 minutes until the edges begin to golden. This pre-baking prevents a soggy bottom.
While the crust bakes, caramelize the 1.5 cups yellow onions in a skillet over medium-low heat with a pinch of salt, stirring frequently for 15-20 minutes until deeply golden and sweet. Meanwhile, crumble the 8 oz cooked bacon into small, even pieces. In a separate bowl, whisk together the 3 whole large eggs, 1 cup heavy cream, 0.5 cup whole milk, 1.5 cups sharp white cheddar cheese, 0.5 teaspoon ground black pepper, and 0.25 teaspoon freshly grated nutmeg until smooth.
Layer and Bake to Golden Perfection
Spread the caramelized onions evenly over the pre-baked crust, followed by the crumbled bacon. Pour the egg mixture over the filling, using a spatula to distribute it evenly. The custard should come about ½-inch below the crust's top edge—this prevents overflow during baking. Transfer the quiche to the oven and bake for 35-40 minutes until the custard is set but still slightly jiggly in the center (it will continue thickening as it cools).
For that signature crispy finish, increase the oven temperature to 425°F during the last 5 minutes of baking. This broiling step creates a golden-brown crust while keeping the custard creamy inside. Watch closely—you want the edges to turn deep golden brown while the center remains just set. Let the quiche rest for 15 minutes before slicing to allow the filling to fully set and the juices to redistribute.
Pro Tips For Making Bacon Cheese And Onion Quiche
- Chill the Dough Properly: Stick the pie crust dough between two sheets of parchment paper, then slap it in the freezer for 15 minutes before rolling. I used to skip this and ended up with a sad, uneven crust—especially when working with all-purpose flour, which doesn’t hold shape like pie dough mix. The cold makes it actually pliable, not brittle.
- Cook the Bacon Until Crisp: Don’t just render the fat—get that bacon crackling and golden before chopping it. I learned this the hard way when my quiche filling tasted greasy instead of rich. A few minutes extra at medium heat makes all the difference, and the flavor carries through the whole dish.
- Prevent a Soggy Bottom: Blind-bake the crust for 8–10 minutes with a pie weight or dried beans before adding the filling. Skimping here means a gummy, undercooked crust—no one wants that. Trust me, the extra step guarantees a crisp base that holds up to the creamy filling.
- Upgrade with Caramelized Onions: Sauté the onions in a little of the bacon fat until deeply browned, about 20 minutes. Yes, it takes time, but the sweetness cuts through the saltiness of the bacon and cheese, giving the quiche real depth. Skip this, and you’re missing out on flavor.
Creative variations of this bacon cheese and onion quiche
Breakfast-for-Dinner Twist
Turn this quiche into a hearty dinner by adding 8 oz cooked ground sausage (Italian or chorizo work well) to the filling. Increase the baking time by 5-7 minutes to ensure the sausage is fully cooked through.
Serve with a side of roasted Brussels sprouts or a simple garlic green bean salad for a balanced meal. The extra protein keeps everyone full longer, making it perfect for weeknight dinners. 🍽️
Gluten-Free Crust Swap
Use a pre-made gluten-free pie crust like Trader Joe’s GF Crust or King Arthur GF Flour Mix for the same flaky texture. Follow package instructions for pre-baking—most require 20 minutes at 375°F with pie weights. For extra crispiness, brush the crust with melted butter before baking.
The filling remains unchanged, so the flavor stays rich and satisfying. This adaptation works for anyone avoiding gluten but still craving a classic quiche. 🌾
Spicy Kick with Jalapeños
Add ½ cup diced jalapeños (seeds removed for mild heat) to the filling for a Southwestern-inspired twist. Cook them with the onions to soften and mellow the heat. For extra depth, sprinkle ½ teaspoon smoked paprika over the custard before baking.
Serve with sour cream or avocado slices to balance the spice. This variation is a crowd-pleaser at brunch gatherings. 🌶️
Veggie-Packed Variation
Boost nutrition by adding 1 cup spinach (chopped) and ½ cup mushrooms (sautéed) to the filling. Fold the greens into the custard mixture just before pouring into the crust. For extra flavor, toss the mushrooms with 1 teaspoon thyme while sautéing.
This version keeps the quiche rich but adds a fresh, earthy dimension that pairs beautifully with the bacon and cheese. 🥬
Mini Quiches for Appetizers
Divide the dough and filling into 6 mini muffin tins (greased) for bite-sized appetizers. Bake at 375°F for 18-20 minutes until golden. These make perfect game-day snacks or holiday appetizers.
For extra flair, top with crumbled bacon bits and a sprinkle of fresh chives before serving. They’re easy to customize—swap in goat cheese or sun-dried tomatoes for variety. 🍴
Sweet Onion Swap
Replace yellow onions with 1.5 cups sweet onions (like Vidalia) for a milder, sweeter flavor. Caramelize them as usual, but reduce the cooking time to 10-12 minutes to prevent burning.
Pair with applewood-smoked bacon for a fall-inspired twist. The natural sweetness balances the savory cheese beautifully, making this a great option for seasonal menus. 🍎

Frequently asked questions
Can I make this quiche ahead of time?
Assemble the quiche (without baking) up to 24 hours ahead and refrigerate. When ready to bake, remove from the fridge and let it sit at room temperature for 30 minutes before baking. Add 5-10 minutes to the baking time since it will be cold. The flavors develop beautifully overnight, making this perfect for brunch prep.
Why is my crust soggy after baking?
Soggy crusts usually happen when the filling isn't fully set or the crust wasn't pre-baked long enough. Always blind-bake your crust for 15-20 minutes before adding filling. Also, ensure your custard is thick enough (it should coat the back of a spoon) and that the oven temperature is accurate. A 375°F oven should give you a crispy crust and set custard.
What's the best way to reheat leftovers?
Quiches reheat best at 350°F for 10-12 minutes covered with foil to prevent drying. For extra crispiness, place the slices on a baking sheet and broil for 2-3 minutes at the end. Microwaving works in a pinch (30 seconds), but it can make the crust rubbery. Leftovers keep well for 4 days in the fridge.
Can I use cream cheese instead of cheddar?
Yes, but the texture will be richer and creamier. Replace 1.5 cups cheddar with 8 oz cream cheese (room temperature) mixed into the custard. The quiche will have a softer, almost soufflé-like quality. For balance, reduce the heavy cream by ¼ cup to prevent a greasy filling. Pair with sharp cheddar for the best flavor combo.
How do I make this quiche vegetarian?
Swap the bacon for 8 oz plant-based bacon (like coconut-based brands) or ½ cup cooked tempeh crumbled. Use 1 cup mushrooms sautéed with onions for umami depth. For extra protein, add ½ cup chickpeas (rinsed and drained). The custard and cheese will still provide richness, making it satisfying for vegetarians.
