Ingredients You’ll Need for This Caramelized Onion and Bacon Quiche

this RECIPE

The key to this dish lies in selecting the right ingredients that complement each other without overpowering. I always opt for fresh, locally sourced onions and thick-cut bacon if possible, as they bring a richer flavor and better texture. When I lived in England, caramelizing onions was a weekly ritual—there’s something almost meditative about watching them transform slowly. Using good-quality eggs and whole milk or cream ensures a custard that’s silky and smooth, which is what really elevates the quiche from everyday to special.

• 1 pre-made pie crust (9-inch), or homemade if you’re feeling adventurous
• 3 large yellow onions, thinly sliced
• 6 slices thick-cut bacon
• 4 large eggs
• 1 cup whole milk
• 1/2 cup heavy cream
• 1 cup shredded Gruyère or sharp white cheddar cheese
• 2 tablespoons unsalted butter
• 1 teaspoon fresh thyme leaves (optional)
• Salt and freshly ground black pepper, to taste

Substitutions: If you prefer, turkey bacon or pancetta work wonderfully. For cheese, Emmental or mozzarella can be used, though the flavor will be milder.

Steps to Create Your Caramelized Onion and Bacon Quiche

1. Preheat your oven to 375°F (190°C). If using a homemade crust, roll it out and fit it into your pie dish, then prick the base with a fork.
2. Cook the bacon in a skillet over medium heat until crisp. Remove and drain on paper towels, then chop roughly. Reserve some bacon fat in the pan.
3. Add butter to the bacon fat and stir in the sliced onions. Cook over low heat, stirring occasionally, for about 30-40 minutes until onions are golden and caramelized. Patience here is key—don’t rush this step.
4. In a mixing bowl, whisk together eggs, milk, cream, salt, pepper, and thyme if using.
5. Sprinkle half the cheese evenly over the pie crust. Spread the caramelized onions and bacon on top, then cover with the remaining cheese.
6. Pour the egg custard mixture carefully over the filling, ensuring it’s evenly distributed.
7. Bake for 35-40 minutes, or until the custard is set and the top is lightly golden. A knife inserted in the center should come out clean.
8. Let the quiche cool for about 10 minutes before slicing. This rest time helps it set further and makes for cleaner slices.

Tips for Making the Best Caramelized Onion and Bacon Quiche

Getting this quiche just right is about respecting the process and embracing a few kitchen tricks I picked up along the way. Caramelizing onions slowly is worth every minute because it builds such rich flavor. Also, balancing the custard’s texture is crucial to avoid a rubbery quiche. I remember my early cooking attempts where impatience led to underdone or watery results—so take your time and trust the process.

• Use a heavy-bottomed skillet for even heat distribution when caramelizing onions.
• Don’t rush the onion cooking—low and slow is the secret to deep flavor.
• Blind bake the crust for 10 minutes before adding filling if you want a crispier base.
• Whisk eggs and dairy thoroughly but gently to avoid air bubbles which can create holes in the custard.
• Let the quiche rest after baking to firm up and develop flavor fully.

Serving Suggestions and Pairings

This quiche shines on many occasions—from a leisurely weekend brunch to a simple weekday supper. I often serve it with a bright salad to cut through the richness, especially when my kids are around and their pancake obsession needs balancing out. It’s also a lovely dish to bring to potlucks or picnics, as it’s delicious warm or at room temperature.

• Pair with a crisp white wine like Sauvignon Blanc or a sparkling water with lemon
• Serve alongside a fresh green salad with a tangy vinaigrette or a light tomato salad
• Add roasted seasonal vegetables like asparagus or carrots for a fuller meal

Whether it’s a cozy family dinner or entertaining friends, this quiche never fails to impress and fill the room with warmth.

Storage and Reheating Tips

Proper storage ensures you can enjoy leftovers just as much as the fresh dish. From my experience as a busy mom, quiche is a lifesaver when made ahead, so knowing how to keep it tasting fresh is essential.

• Store any leftovers in an airtight container in the refrigerator for up to 3 days
• Reheat slices gently in a 325°F oven for 10-15 minutes to retain crispness
• For a quicker option, microwave on medium power in short bursts, adding a splash of cream to keep it moist
• Quiche can also be frozen—wrap tightly in foil and freeze for up to 1 month; thaw overnight in the fridge before reheating
