A well-made quiche is the answer to so many entertaining dilemmas. Whether I’m hosting a casual brunch, planning a special breakfast, or serving dinner to friends, this Breakfast Quiche seems to always fit the occasion perfectly. A substantial dish that’s both elegant and simple, it combines custardy eggs and cheese with tender leeks and smoky bacon, all wrapped in flaky pastry.
This quiche adapts to whatever ingredients you have on hand and whatever meal you’re planning. I often switch up the fillings based on what’s in my fridge – different meats, cheeses, or purely vegetarian versions all work beautifully. The kind that perches comfortably on the plate next to a leafy salad or mound of steamed vegetables to make a meal, even a modest slice feels substantial. The silky custard base transforms basic eggs and cream into something luxurious without much effort.

Ingredients to Make Breakfast Quiche
- Pie Crust: An unbaked, deep-dish pie crust is essential here – either homemade pie dough (ideally unbaked Lard Pie Crust) or store-bought works well.
- Bacon: Choose thick-cut bacon for the best texture. It holds its shape better when diced and provides more substantial bites throughout the quiche.
- Leeks: Look for firm leeks with crisp, dark green tops and white bases. Smaller leeks tend to be more tender and have a milder flavor.
- Heavy Cream: The high fat content creates that silky custard texture we’re after.
- Milk: Whole milk adds richness while keeping the custard light. 2% works too, but I don’t recommend nonfat milk.
- Eggs: Large eggs are the standard for baking. Make sure they’re room temperature for the smoothest custard.
- Thyme: Fresh or dried both work beautifully. I often use dried since I keep it on hand, but fresh adds a lovely visual element.
- Gruyère Cheese: Its nutty flavor is perfect here, but a sharp cheddar makes a great substitute. Either way, grate it yourself for the best melting.
- Salt and Black Pepper: Fresh cracked pepper makes a noticeable difference in the final flavor.
About Leeks and How to Clean Them
If you haven’t cooked with leeks before, you’re in for a treat. In a skillet, they melt down becoming soft and buttery with subtle onion flavor. They’re mild and tender in the spring and firmer, but deeply flavorful in the late fall. In the later months, they take a bit longer to soften, but are equally delicious. If you can’t find them, an ample amount of green onions (about 1 cup thinly sliced) work well in this quiche.
Fine grit often hides between a leek’s tender layers. To clean them, submerge the thinly sliced leeks in a bowl of cold water and swoosh them around with your hands to allow any dirt to sink to the bottom. Lift the rinsed leeks out with a slotted spoon or your hands and transfer to a clean bowl. Don’t drain them in a colander – you’ll pour the settled dirt right back over the clean leeks.
5 Recipe Tips
- Bacon Slicing Tip: Cut bacon while it’s still slightly frozen – it’s much easier to get clean, even strips.
- Temperature Matters: Let your eggs and dairy come to room temperature for the smoothest custard.
- Blind Baking: Always partially cook your crust before adding the filling to ensure a crisp bottom – this prevents the dreaded soggy bottom that can happen with custard pies.
- Doneness: The quiche is done when it’s set around the edges but still has a slight wobble in the center – it will continue to set as it cools.
- Serving: Let the quiche rest for at least 15 minutes before cutting. A serrated knife works best for clean slices.
Recipe Options
- Different Cheeses: Swap Gruyère for sharp cheddar cheese, Monterey Jack, gouda, or fontina – any good melting cheese works well here.
- Meat Options: Replace bacon with diced ham, crumbled sausage, or pancetta – or omit for a vegetarian version.
- Vegetable Variations: Green onions work perfectly in place of leeks, or try sautéed mushrooms, bell peppers, spinach, or asparagus.
- Make It Mini: Use the same filling in a muffin tin with pre-baked pie crust circles for individual servings – reduce the baking time and watch carefully for doneness.
Storage and Reheating
Store covered in the refrigerator for up to 3 days or wrapped in foil in the freezer for up to 3 months.
To reheat refrigerated quiche: Place on a parchment-lined baking sheet, cover with foil and warm in a preheated 350˚F oven for 15 to 20 minutes.
To reheat frozen quiche: Do not thaw. Cover with foil and warm in a preheated 350˚F oven for 30 to 45 minutes, until internal temperature reaches 160-165˚F.
There’s something satisfying about pulling a hot quiche from the oven – flaky crust, silky filling, and those lovely aromas of bacon and leeks. While a quiche takes time to make, this recipe reminds me why it’s worth it.

How to Make Breakfast Quiche
Make and blind bake pie crust at 375˚F for 12 minutes – ideally this Lard Pie Crust or other homemade pie crust. (A store bought unbaked, deep dish pie crust also works.)
Cook leeks and bacon until leeks are tender and bacon is lightly crisp. Remove from heat.
Whisk eggs, cream and milk together and season with salt and pepper. Stir in shredded cheese and bacon and leek mixture.
Pour egg mixture into partially baked pie crust (see blind baking instructions above). Bake until golden in a 375°F oven (cover edges with foil or pie crust shield if they’re getting too brown. Serve warm, at room temperature or cold from the refrigerator.

Ingredients
- 9 inch unbaked Lard Pie Crust or store-bought deep dish unbaked pie crust
- 1/2 pound bacon cut crosswise into thin strips (lardons)
- 2 large leeks cut in half lengthwise and thinly sliced into half rounds
- 3/4 cup heavy cream
- 1/4 cup whole milk or 2%
- 6 large eggs
- 1/4 teaspoon fine sea salt
- 1/4 teaspoon freshly ground black pepper
- 1/4 teaspoon dried thyme or 1/2 teaspoon fresh minced thyme
- 4 ounces Gruyère cheese shredded, or cheddar
Instructions
- Place unbaked pie crust in deep dish pie plate; flute edges if desired. Cover and refrigerate for at least 30 minutes and up to 3 days.
- When you're ready to bake, preheat oven to 375 °F (191 °C). Line pie crust with parchment paper or foil and fill with pie weights or dried beans. Bake 12 minutes. Remove parchment paper and weights and prick bottom and sides of crust all over with a fork. Return to oven and bake 8 minutes more. Remove and set aside; leave oven on.
- Meanwhile, cook bacon and leeks in a large skillet until bacon is lightly crisp and leeks are tender. Remove from heat and set aside to cool.
- In a large bowl, whisk together cream, milk, eggs, salt, pepper and thyme until smooth. Stir in cheese and bacon and leek mixture.
- Pour egg mixture into partially baked pie crust and bake 40 minutes, or until the center is just set (cover pie crust edges with foil or a pie crust shield in the last 15 to 20 minutes of baking if crust is getting too brown). Let stand at least 15 minutes before cutting. Serve quiche warm or at room temperature.
Notes
- To reheat leftover quiche from the refrigerator; cover with foil and warm in a preheated 350˚F oven for 15 to 20 minutes. To reheat frozen quiche (do not thaw before reheating), follow the same directions, but increase the reheating time to 30 to 45 minutes or when the internal temperature reaches 160˚F to 165˚F.

I have the perfect pan to make this! Love the addition of the leeks.
Thank you, Mimi! I love how leeks get so buttery as they cook down.
I haven’t made a quiche in months, and now I’m craving one! This breakfast version looks fantastic, Marissa. Don’t you love how quiches are a blank canvas for all sorts of other ingredients/flavors? I need to make this recipe soon! (It would be great for the holidays, right??)
Absolutely! Thanks, David.
I have baked my quiche for breakfast tomorrow morning. Do I let it cool completely before putting in the frig? How long do I warm it coming out of the frig in the morning? 375 degrees?
It is beautiful โค๏ธ
Hi Susie! So glad your quiche turned out well. You should let it cool before covering and refrigerating. Have a look at the section above titled “How to Reheat Quiche” for detailed instructions on reheating chilled or frozen quiche.
Absolutely wonderful quiche – i could eat the whole thing alone in one sitting. May I ask, is it possible to perhaps cut the amount of leaks by half? I loved it, but i think the leek flavor may be strong for some of the picky eaters i will be making this for. Would i need to substitute with anything? Thanks so much!
Sorry one other silly question – if i freeze this, do i have to thaw it out before i bake to reheat?
So glad you enjoyed this! Yes, you can reduce the leeks by half, no need to substitute with anything. Not a silly question at all! You should reheat the quiche from frozen (don’t thaw first) – I’ve made a note of that in the post as well. Thank you for asking.
Could this be prepared the night before and then baked in the morning? Looking for something easy Christmas morning.
Hi there, Lisa. You can make the egg mixture the night before, but you’ll want to pour it into the partially baked crust and bake the day of (otherwise your crust will get soggy in the refrigerator overnight). Alternatively, you can bake the quiche a day ahead and reheat the next day. I hope that helps!
