Appetizers
This basic cheese and onion quiche recipe delivers a golden crust with perfectly caramelized onions and a rich, custardy egg filling that bakes up creamy and satisfying.
The secret lies in slow-cooked onions that melt into sweet, jammy layers while the egg mixture sets to a velvety texture—no shortcuts, just reliable results every time. I’ve perfected this version to balance simplicity with restaurant-quality depth, making it ideal for brunch or a hearty appetizer.
The foundation starts with a classic pie crust—flaky, buttery, and sturdy enough to hold the filling without sogging.
While the crust bakes blind, you’ll caramelize the onions low and slow until they’re tender and deeply flavorful, then mix them into a smooth egg custard with sharp cheddar for that signature tang.
This method ensures the quiche emerges with a crispy, golden-brown top and a filling that’s neither rubbery nor runny.
What sets this recipe apart is the foolproof baking technique: a water bath for even cooking and a precise 375°F temperature that guarantees a creamy center without overbrowning. The result?
A quiche so good it disappears in minutes, with layers of texture—crisp crust, tender onions, and a custard that’s rich but not heavy. Serve it warm with a simple salad or crusty bread for the perfect start to any meal.
Ready in under an hour with just 10 ingredients, this quiche is perfect for beginners and seasoned bakers alike. The instructions walk you through every step, from rolling the crust to testing doneness, so you’ll achieve professional results without stress. Let’s get baking!
Ingredients for basic cheese and onion quiche
Ten essential ingredients for a foolproof quiche with golden crust and velvety custard.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | For pie crust, spooned and leveled |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed, for flaky crust |
| Ice Water 💧 | ½ cup | Plus 1 tbsp for dough |
| Large Yellow Onions 🧅 | 3 whole | Thinly sliced, caramelized |
| Sharp White Cheddar Cheese 🧀 | 1 ½ cups | Shredded, block preferred |
| Large Eggs 🥚 | 6 whole | Room temperature, beaten |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For depth of flavor |
The crust starts with cold butter and flour—never cut the butter with a knife, just pulse it in the food processor for flaky layers. King Arthur flour or Bob's Red Mill yield the best texture. If your butter melts mid-rolling, pop the dough in the fridge for 15 minutes. The onions are non-negotiable: yellow onions caramelize best, and you want them jammy and sweet—not crisp. I always slice mine while the crust bakes blind, so they're ready to go when the custard's mixed.
No sharp cheddar? Pepper Jack or Gruyère work beautifully, though the tang is key here. Short on eggs? Add 2 tbsp cornstarch to the custard to compensate for texture. The heavy cream can be swapped for half-and-half, but trust me on the full-fat version—it makes all the difference. Garlic powder is optional, but if you love garlic, add 1/4 tsp extra. For the crust, Diamond Crystal salt is ideal, but any kosher salt works. If your butter's salted, reduce the added salt by 1/2 tsp.
Prevent a soggy bottom by baking the crust blind with pie weights or dried beans. The custard should be just set in the center when done—about 35-40 minutes at 375°F. Leftovers keep for 4 days in the fridge, but reheat gently to avoid rubbery texture. For make-ahead, assemble the quiche, refrigerate overnight, then bake straight from cold—add 5-10 minutes to baking time. The crust freezes beautifully for up to 3 months, so make extras.

Step-by-step instructions for cheese and onion quiche
Here's how to build a classic quiche with a flaky crust and perfectly caramelized onions.
Prepare the Flaky Pie Crust
In a large bowl, combine the 2.5 cups all-purpose flour and 1.5 teaspoons salt. Cut in the 1 cup cold, cubed unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This ensures maximum flakiness when baked.
Gradually add the 0.5 cup ice water (plus 1 tablespoon extra) while mixing just until the dough comes together. Avoid overworking it—press the dough gently a few times until it holds shape. Shape into a disk, wrap in plastic wrap, and refrigerate for at least 30 minutes to firm up.
Caramelize the Onions
Peel and thinly slice the 3 whole large yellow onions (about 3 cups when sliced). Heat 1 tablespoon olive oil in a large skillet over medium-low heat. Add the onions and cook, stirring occasionally, for 25-30 minutes until deeply golden and tender.
You're looking for onions that are almost jam-like in texture with rich caramelized color. If they start to brown too quickly, reduce the heat. Season with 0.5 teaspoon garlic powder and set aside to cool slightly. These onions will form the flavor base of your quiche.
Assemble the Quiche Filling
Preheat your oven to 375°F. Roll out the chilled pie dough on a floured surface to fit a 9-inch pie dish, leaving a 1-inch overhang. Transfer to the dish and trim the excess. Press the dough up the sides to create a rim, then prick the bottom with a fork and blind-bake for 10 minutes to prevent sogginess.
In a large bowl, whisk together the 6 large eggs, 1 cup heavy cream, 1.5 cups shredded sharp white cheddar cheese, 0.5 teaspoon black pepper, and 0.5 teaspoon garlic powder until fully combined. Fold in the caramelized onions, reserving any liquid from the skillet. Pour the filling into the pre-baked crust.
Bake to Golden Perfection
Bake the quiche for 35-40 minutes until the filling is set and the top is golden brown. A toothpick inserted in the center should come out clean. If the crust starts browning too quickly, tent loosely with aluminum foil.
Remove from the oven and let cool for 10 minutes before slicing. The quiche should be slightly jiggly in the center when hot but firm up as it cools. Serve warm or at room temperature with a simple green salad.
Pro Tips For Making Basic Cheese And Onion Quiche
- Preheat the Dish First: Pop your quiche pan or pie dish into a 375°F (190°C) oven for 5 minutes before adding the crust. I learned this the hard way—skipping it makes the butter in the crust sweat and turn soggy when the filling goes in. (Yes, even if you're impatient like me, give it those 5 minutes.)
- Sweat, Don’t Sear, the Onions: Use medium-low heat and cover the pan for 10-12 minutes to soften the onions without browning. After burning three batches of onions into crispy black bits, I finally figured out: you want them translucent and sweet, not caramelized. Covering speeds it up and keeps the filling from tasting bitter.
- Chill the Crust Before Filling: Let the assembled crust rest in the fridge for 15-20 minutes after adding the filling. I used to rush this, and the cheese would leak out like a sad, melted puddle. A cold crust holds its shape better and prevents a gooey disaster when you cut into it.
- Use Cold Egg Mixture: Whisk your eggs and cream together in a cold bowl—no warm hands here. Cold eggs create a firmer, less watery custard, and they won’t start cooking prematurely when they hit the hot filling. (Your future self will thank you for skipping the warm shortcut.)
Regional styles of these flavors
French Classic
In France, quiche Lorraine is the star, but a cheese and onion variation is equally beloved in rural regions like Normandy. The secret? A double crust—topped with a lattice or full second layer—adds rustic charm.
I’ve made this version with Gruyère cheese instead of cheddar for a nuttier depth, and I always caramelize the onions with a splash of dry white wine (about 2 tablespoons) to mimic bistro techniques. Serve with a baguette and a simple vinaigrette for an authentic touch. 🥖
British Pub Style
British pubs serve quiches as hearty appetizers, often with thick-cut onions and a crispy puff pastry crust instead of pie dough. Swap the all-purpose flour crust for store-bought puff pastry (like Pepperidge Farm) for a shortcut, but brush it with egg wash before baking for extra crispiness.
Add ½ teaspoon English mustard powder to the custard for a subtle tang—it’s a classic pub trick. Pair with mushy peas or a side salad for a full pub experience. 🍻
Southern U.S. Twist
In the American South, quiches often get a smoky kick from Andouille sausage or bacon, but a vegetarian version still shines with sharp cheddar and sweet caramelized onions. For a Southern flair, add ½ teaspoon smoked paprika to the custard and top with crumbled bacon before baking.
Serve with buttermilk biscuits and hot sauce for a brunch crowd-pleaser. I love this version for its bold, comforting flavors. 🌶️
German Rustic
German Käsekuchen (cheese cake) often inspires quiche variations, especially in Bavaria. For a regional twist, replace half the cheddar with Emmental cheese (shredded) and fold in ½ cup cooked applesauce into the custard for sweetness.
Top with a crust of crushed Ritz crackers mixed with melted butter for a no-bake crust option. This version is lighter but still rich—perfect with a dark rye bread on the side. 🍏
Italian Rustic
In Northern Italy, quiches often feature ricotta cheese and sun-dried tomatoes, but a cheese and onion version gets a herbaceous twist. Swap the cheddar for Parmigiano-Reggiano (grated) and add 2 tablespoons chopped fresh rosemary to the custard.
Use whole-wheat pastry flour for the crust and top with thinly sliced prosciutto before baking for a salty-sweet contrast. Serve with a balsamic glaze drizzle for an elegant touch. 🌿

Frequently asked questions
Can I use store-bought pie crust instead of making one from scratch? Store-bought pie crust saves time and still delivers great results. Just
How do I prevent a soggy bottom in my quiche?
The key is blind-baking the crust first. Prick the bottom with a fork, line it with parchment paper, and fill with dried beans or pie weights to weigh it down. Bake for 10 minutes at 375°F before adding the filling. This creates a barrier that keeps the crust crispy.
Can I make this quiche ahead of time?
Yes! Assemble the quiche in the pie dish, cover it tightly with plastic wrap, and refrigerate for up to 24 hours. When ready to bake, simply add 5-10 minutes to the baking time (it may need the extra time since it's cold). Leftovers keep well in the fridge for 4 days—just reheat gently in the oven or microwave to avoid a rubbery texture.
What’s the best way to reheat leftover quiche?
Slice the quiche into individual portions and reheat in a 350°F oven for 10-15 minutes until warmed through. For a quick fix, microwave slices on medium power for 45-60 seconds, covered with a damp paper towel to keep it moist. Avoid high heat to prevent the crust from becoming tough.
Can I substitute heavy cream with something else?
You can replace the heavy cream with half-and-half or whole milk, but the custard will be slightly lighter. For richness, add 2 tablespoons sour cream or Greek yogurt to compensate. The texture will still be creamy, but the depth of flavor may change a bit.
