Caramelized onions, on their own, are a culinary marvel.

This thoughtful balance of sweet, savory, and fresh is precisely why this caramelized onion and sausage quiche recipe isn’t just good; it’s outstanding.

However, its irresistible appeal isn’t limited to holidays. I’ve made countless quiches over the years, but this particular recipe consistently ranks as my absolute favorite. Its savory profile is so rich and satisfying, making it a fantastic centerpiece for any breakfast or brunch menu. My husband, with his love for anything involving sausage and cheese, was an immediate fan, which was no surprise.
What truly solidified this recipe’s “perfect” status for me was the reaction of my teenage daughter. Known for her discerning palate and general skepticism towards most of my culinary endeavors – not to mention her general disinterest in meat – her enthusiastic approval was a genuine shock. She not only enjoyed it but openly praised it and continued to eat it for days! This unexpected endorsement from my toughest critic speaks volumes about the quiche’s universal appeal. If it can win her over, it can certainly win over anyone.
Essential Ingredients for Your Perfect Sausage Quiche
Crafting this delicious sausage and caramelized onion quiche requires a selection of readily available ingredients, ensuring that you can find everything you need at your local grocery store. There’s nothing exotic here, just simple components that, when combined, create magic.
- Pie Dough: The foundation of any great quiche. You have the flexibility to either purchase a pre-made, high-quality pie crust for convenience or embrace the rewarding process of making your Perfect Pie Crust from scratch. A good crust provides the necessary structure and a buttery complement to the rich filling.
- Onions: Two large white onions are specified, which might seem like a substantial amount initially. However, through the caramelization process, they cook down significantly, concentrating their flavors and transforming into a sweet, jam-like consistency that is absolutely crucial to this quiche’s signature taste. Yellow onions are also a suitable substitute if white onions are unavailable.
- Extra Virgin Olive Oil, Granulated Sugar, and Vegetable Stock: These ingredients are key to achieving perfectly caramelized onions. The olive oil provides a medium for slow cooking, the sugar aids in the browning and sweetening process, and the vegetable stock (or apple juice) is used at the end to deglaze the pan, capturing all those flavorful browned bits and adding another layer of depth.
- Bulk Breakfast Sausage: Opt for the kind found in a tube. This type of sausage offers a hearty, savory base that pairs beautifully with the sweet onions. You can choose mild, sage, or even hot varieties depending on your preference to adjust the spice level of your quiche.
- Cheeses: Swiss and Sharp Cheddar: This combination of cheeses offers a wonderful balance of flavors and textures. Swiss cheese melts beautifully and adds a nutty, slightly sweet note, while sharp cheddar brings a robust, tangy flavor that cuts through the richness of the sausage and eggs, adding complexity to every bite.
- Fresh Herbs: Sage and Flat-Leaf Parsley: Fresh herbs are essential for bright, aromatic highlights. Sage provides an earthy, slightly peppery flavor that is a classic complement to sausage, while fresh flat-leaf parsley adds a clean, verdant freshness that lifts the entire dish.
- Eggs, Heavy Cream, and Dijon Mustard: These three form the luscious, creamy custard base of the quiche. The eggs provide structure, the heavy cream ensures a rich and silky texture, and a touch of Dijon mustard adds a subtle tang and enhances the savory notes without overpowering them. It’s a secret ingredient that truly elevates the custard.
- Seasonings: Kosher Salt and Fresh Cracked Pepper: Essential for seasoning the quiche to perfection. Kosher salt brings out the inherent flavors of all the ingredients, and fresh cracked pepper adds a subtle warmth and aromatic finish.
Crafting Your Delicious Sausage and Caramelized Onion Quiche
Making this incredible sausage quiche is surprisingly straightforward, despite the gourmet result. The most time-consuming step is caramelizing the onions, but please believe me when I say, the rich, sweet depth they achieve is absolutely worth every minute of patient cooking. The beauty of caramelizing onions is that it requires minimal effort; you don’t need to constantly hover over them. Just an occasional stir is enough to guide them to their golden, tender perfection. This hands-off process makes it an ideal task to start while you prepare other components of the dish.
Once your onions have transformed into their sweet, sticky glory, the rest of the assembly is a breeze. You’ll simply brown the breakfast sausage, layering it along with the aromatic herbs and a generous blend of cheeses into your prepared pie crust. Finally, a rich, creamy egg custard is poured over the top, ready for its journey into the oven. The oven then works its magic, baking everything together into a beautifully puffed, golden-brown masterpiece.
The result is a truly fantastic quiche that is versatile enough for any occasion. Imagine serving this savory delight at a festive spring buffet, a cozy Christmas breakfast, an elegant Easter brunch, or even a charming baby shower. Its impressive appearance and unforgettable flavor make it suitable for any gathering where you want to serve something truly special and comforting.
Tips for a Perfect Sausage and Caramelized Onion Quiche
Achieving a perfectly cooked quiche, especially one with a golden, crisp bottom crust, can sometimes be a challenge. Here are some essential tips to ensure your Sausage and Caramelized Onion Quiche turns out flawless every time:
- Ensure a Cooked Crust: The key to any great quiche is a fully cooked bottom crust. Raw or undercooked pie dough is simply not appealing. To prevent a soggy bottom, make sure your oven is preheated to the correct temperature. If you find the top of the quiche is browning too quickly before the filling is set and the crust is cooked, loosely tent the quiche with aluminum foil. This protects the top from over-browning while allowing the rest of the quiche to cook through. Some bakers even blind-bake their crust for 10-15 minutes before adding the filling, especially if using a homemade crust, to give it a head start.
- Advance Preparation and Storage: This sausage quiche is a fantastic make-ahead dish. You can bake it a day in advance and reheat it gently in the oven (covered with foil) until warmed through. This makes it perfect for entertaining or busy mornings. Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. For longer storage, this quiche also freezes beautifully. Once cooled, wrap individual slices or the whole quiche tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 2-3 months. To reheat from frozen, thaw in the refrigerator overnight, then warm in a moderate oven.
- Onion Varieties: While white onions are specified for their crisp texture and balanced sweetness, yellow onions are an excellent substitute. They caramelize just as beautifully, offering a similar depth of flavor. Red onions can also be used for a slightly sharper initial taste and a beautiful purplish hue once caramelized, though they are generally sweeter.
- Sausage Selection: The recipe suggests mild bulk breakfast sausage, which provides a classic, comforting flavor. However, feel free to customize to your taste. For a more aromatic quiche, opt for sage-flavored sausage. If you enjoy a little heat, a hot bulk sausage will add a pleasant kick. For a lighter option, turkey sausage can be used, though you might need to add a bit more olive oil when browning as it contains less fat. Vegetarian sausage crumbles can also be used as a delicious plant-based alternative.
- Don’t Overmix the Custard: When whisking the eggs, cream, Dijon, and seasonings, mix just until combined. Overmixing can incorporate too much air, leading to a bubbly or uneven custard texture. A gentle whisk is all that’s needed for a smooth, creamy filling.
- Resting Time is Crucial: After baking, resist the urge to cut into the quiche immediately. Allow it to sit for at least 5-10 minutes (or even longer for easier slicing). This resting period allows the custard to fully set, ensuring clean slices and preventing the filling from oozing out.
- Customization Opportunities: While this recipe is perfect as is, quiche is highly adaptable. Consider adding a handful of fresh spinach or sautéed mushrooms along with the sausage and onions for added vegetable goodness. Experiment with different cheese combinations; gruyere or provolone could also work wonderfully.

Ingredients
- 1 prepared dough for 1 pie crust
- 2 large white onions sliced in ½-inch slices
- 1 Tbsp extra virgin olive oil
- 1 tsp granulated sugar
- ¼ cup vegetable stock or apple juice
- 1 bulk breakfast sausage cooked and fat drained
- ¾ cup shredded Swiss cheese
- ¼ cup shredded sharp cheddar cheese
- 1 Tbsp fresh chopped sage leaves
- 1 Tbsp fresh chopped Italian flat-leaf parsley
- 4 large eggs
- ½ cup heavy cream
- 2 tsp Dijon mustard
- 1 tsp kosher salt
- ⅛ tsp fresh cracked pepper
Instructions
-
Heat the olive oil in a saute pan over medium heat. Add the onions and sugar, and cook on medium until they begin to soften and release moisture. Reduce the heat to low and cook slowly, stirring occasionally, for about 45 minutes or until the onions are very soft, deeply golden, and thoroughly caramelized.
-
Increase the heat under the onions to medium-high. Once they start to sizzle, add the vegetable stock or apple juice (whichever you are using). Cook for approximately 3 minutes, stirring constantly, to deglaze the pan and boil off most of the liquid. This step incorporates all the flavorful browned bits into the onions. Remove from heat and set aside. Season lightly with a pinch of kosher salt.
-
Preheat oven to 400°F (200°C).
-
Line the pie dough into a 9-inch pie plate and crimp or flute the edge decoratively. In the prepared pie crust, layer the cooked sausage, followed by the caramelized onions, then sprinkle with the fresh herbs, and finally the shredded Swiss and sharp cheddar cheeses.
-
In a separate bowl, whisk together the eggs, heavy cream, Dijon mustard, kosher salt, and fresh cracked pepper until just combined. Slowly and carefully pour this custard mixture over the layered ingredients in the pie crust. Bake at 400°F (200°C) for 45 minutes, or until the top is beautifully puffed and very golden brown. If the top begins to brown excessively before the quiche is fully cooked, lightly cover it with aluminum foil mid-way through baking. It’s crucial to ensure the full cook-time to guarantee the crust cooks completely and the custard sets.
-
Remove the quiche from the oven and let it rest for 5-10 minutes before slicing and serving. This allows the custard to fully set for cleaner cuts.
