Ingredients for basic cheese and onion quiche
A flaky crust and melty cheese combo—simple ingredients for a quiche that tastes restaurant-worthy.
| Ingredient | Amount | Notes |
|---|---|---|
| Pie Crust (Store-Bought or Homemade) 🥧 | 1 whole | Pre-baked for crispiness |
| Large Eggs 🥚 | 4 whole | Room temperature preferred |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Whole Milk 🥛 | ½ cup | Warmed slightly |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, not pre-shredded |
| Yellow Onions 🧅 | 1 ½ cups | Caramelized, finely chopped |
| All-Purpose Flour 🌾 | ¼ cup | For thickening custard |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Garlic Cloves 🧄 | 2 cloves | Minced for depth |
| Unsalted Butter 🧈 | 1 tbsp | For crust brushing |
| Fresh Chives 🌿 | ¼ cup | Chopped, for garnish |
The crust is where it all starts. Store-bought works in a pinch, but homemade gives that extra-crispy edge. I grab the Pillsbury refrigerated crust when I'm short on time, but for the best results, make your own with all-purpose flour, cold butter, and ice water. The key? Chill the dough for at least 30 minutes before rolling—this prevents shrinking. For the cheese, shred your own (pre-shredded has anti-caking agents that make it less melty). Sharp cheddar is non-negotiable—it's what gives that perfect tangy bite.
No heavy cream? Half-and-half or whole milk works, though the texture will be slightly lighter. Caramelizing the onions is worth the time—20-25 minutes on low heat turns them sweet and golden. Skip this step, and you'll miss that depth of flavor. Fresh chives add a bright finish, but dried chives at half the amount are fine if you're in a hurry. The garlic? Roast it first for a sweeter, more mellow flavor—just toss whole cloves in olive oil at 400°F for 15 minutes. Game-changer.
This quiche reheats beautifully—just pop slices in the oven at 350°F for 5-7 minutes until the edges are crispy again. Keeps for 4 days in the fridge, wrapped tightly in foil. Freezes for 3 months if you portion it into individual slices before freezing. The secret to make-ahead success? Assemble the quiche, then refrigerate it overnight before baking. The flavors meld, and you avoid the dreaded soggy bottom.

Step-by-step instructions for cheese and onion quiche
Here's how to create a golden, flaky quiche with perfectly caramelized onions and melty cheese.
Prepare the Caramelized Onion Filling
In a large skillet, melt the 1 tablespoon unsalted butter over medium heat. Add the 1.5 cups finely chopped yellow onions and cook for 15-20 minutes, stirring occasionally, until they turn a deep golden brown color. This slow cooking process develops their natural sweetness and creates that rich, caramelized flavor we want.
After about 10 minutes, add the 2 minced garlic cloves and cook for another 1 minute until fragrant. Remove the skillet from heat and let the onions cool slightly. I like to sprinkle them with a pinch of salt while they cool—this helps enhance their flavor as they sit. The onions should be soft enough to mash slightly with a fork when cool, but still hold their shape.
Mix the Custard Filling
In a large bowl, whisk together the 4 whole large eggs, 1 cup heavy cream, and 0.5 cup warmed whole milk until fully combined. Add the 0.25 cup all-purpose flour, 0.5 teaspoon salt, and 0.25 teaspoon ground black pepper, whisking until smooth. This creates a thick, velvety custard base that will hold the cheese and onions beautifully.
Next, fold in the 1.5 cups shredded sharp cheddar cheese and the cooled caramelized onions using a spatula. Be gentle to avoid deflating the mixture too much—you want the cheese to stay in chunks for that classic quiche texture. The filling should be thick but pourable. If it looks too thick, whisk in 1-2 tablespoons of milk to loosen it slightly.
Assemble and Bake the Quiche
Preheat your oven to 375°F. Place the pre-baked pie crust on a baking sheet lined with parchment paper. Brush the crust generously with any remaining melted butter from the onion cooking process—this adds extra flavor and helps create that perfect golden-brown finish.
Pour the custard mixture evenly into the crust, spreading it out to the edges. The filling should come about ¾ of the way up the sides—this prevents the crust from becoming soggy. Sprinkle the 0.25 cup chopped fresh chives evenly over the top for a pop of color and fresh flavor.
Bake Until Golden and Set
Bake the quiche for 35-40 minutes until the center is just set and the edges are golden brown. You'll know it's ready when the custard has a slight wobble in the center but springs back when gently touched—it should still be slightly jiggly, as it continues to set as it cools.
For the last 5 minutes of baking, you can place the quiche under the broiler (watched closely) to achieve that perfect golden-brown crust on top. Let it cool for 10-15 minutes before slicing—this resting time allows the filling to fully set and makes it easier to serve without the center collapsing.
Pro Tips For Making Basic Cheese And Onion Quiche
- Preheat the Dish First: Blind-bake that pie crust for 8–10 minutes at 375°F before adding filling—no, skipping this won’t make you a hero. The crust absorbs filling like a sponge, and you’ll end up with a soggy bottom instead of a sturdy base. (Yes, even if you’re using store-bought crust.)
- Use Room-Temp Cream: Cold heavy cream makes the custard grainy and uneven. Let it sit out for 30 minutes before mixing—it blends smoother and cooks more evenly. I learned this the hard way when my quiche looked like it had been shaken in a snow globe.
- Don’t Overmix the Eggs: Stir the egg mixture just until the yolks and whites combine—no need to whip it into meringue. Overmixing adds air, which causes cracks and uneven baking. Think "gentle enough to soothe a fussy cat," not "aggressive smoothie."
- Upgrade with Caramelized Onions: Skip raw onions—they’ll turn mushy and watery. Sauté 1½ cups thinly sliced onions in butter until deep golden (15–20 minutes), then sprinkle with a pinch of salt. The flavor change is night-and-day, and it takes less than 30 minutes total. (Your future brunch guests won’t believe it’s the same dish.)
Health benefits of this dish
Protein-Packed Breakfast
This quiche delivers a solid 20 grams of protein per serving—thanks to the eggs and cheddar—making it an excellent choice for breakfast or a post-workout meal. The combination of whole eggs and sharp cheddar provides all nine essential amino acids, supporting muscle repair and keeping you full for hours.
I always make a double batch on Sundays to grab for quick lunches during the week. 💪
Vitamin D Boost
Eggs are one of the few natural food sources of vitamin D, with each serving of this quiche providing about 20% of your daily needs. This nutrient is crucial for bone health, immune function, and mood regulation.
Pair this quiche with a side of spinach salad to boost your vitamin D even further—spinach contains compounds that help your body absorb this essential nutrient more efficiently.
Creamy Texture Benefits
The heavy cream and whole milk in the custard create a rich, velvety texture while adding healthy fats that support brain function and satiety. Unlike lighter versions made with skim milk, this quiche keeps you satisfied longer.
I've found that the full-fat dairy actually enhances nutrient absorption—your body absorbs fat-soluble vitamins like A and E from the cheese more effectively when paired with healthy fats.
Fiber from Onions
While onions might seem like a simple ingredient, they pack 3 grams of fiber per serving in this quiche, supporting digestive health. The caramelization process actually increases their antioxidant content—so you're getting more health benefits than you might expect from this classic flavor combination.
I always use yellow onions for their natural sweetness, but red onions would add a nice pop of color too.
Low-Carb Option
For those watching their carb intake, this quiche can easily be adapted by using a low-carb crust made from almond flour or coconut flour. The filling remains naturally low in carbs thanks to the eggs, cheese, and onions.
I've made this version with cauliflower crust and was surprised at how well it held up—just brush it with extra butter before baking to prevent drying.
Calcium-Rich Choice
With 1.5 cups of sharp cheddar, this quiche provides 30% of your daily calcium needs per serving. Calcium is essential for bone health, muscle function, and even maintaining a healthy weight. The sharpness of the cheese also enhances the flavor profile, making each bite more satisfying.
I like to use white cheddar for a slightly milder taste that still delivers all the calcium benefits.

Frequently asked questions
Can I make this quiche ahead of time?
Assemble the quiche in your pie dish, cover it tightly with plastic wrap, and refrigerate overnight. When ready to bake, pull it from the fridge (no need to thaw) and bake as directed. This actually improves flavor as the ingredients meld. For make-ahead baking, refrigerate the assembled quiche for 4-6 hours before baking at 375°F for 45-50 minutes (the extra time accounts for the cold start).
What can I substitute if I don't have sharp cheddar?
Use Gruyère for a nutty flavor or Parmesan mixed with mozzarella for a sharper bite. Avoid pre-shredded cheese—it contains anti-caking agents that prevent proper melting. For a dairy-free option, swap in nutritional yeast (for cheesy flavor) plus vegan cheese shreds, but expect a slightly different texture. Always shred your own cheese for best results.
Why did my quiche come out soggy?
Sogginess usually means the crust wasn't pre-baked long enough or the custard was too wet. Always bake the crust for 12-15 minutes at 375°F until golden before adding filling. For extra insurance, sprinkle 1 tablespoon flour in the crust before adding custard. If your mixture looks too thick, whisk in 1 tablespoon milk at a time until it's pourable but still holds shape.
Can I use a different type of crust?
Yes! Try a pâte brisée (French shortcrust) for extra flakiness or a gluten-free crust made with almond flour. For a lighter texture, use a phyllo dough crust (just brush with butter between layers). If using a pre-made crust, choose one with at least 20% butter fat—this prevents a greasy or crumbly result. Always pre-bake any crust to avoid sogginess.
How do I reheat leftovers without drying them out?
Slice the quiche and reheat portions in a 350°F oven for 5-7 minutes on a baking sheet until warm through. For microwave reheating, cover with a damp paper towel and heat in 30-second intervals at 50% power. Never reheat to steaming—this makes the crust rubbery. For best texture, store leftovers in the fridge for no more than 4 days.
