Introduction
Quiche is a versatile dish that can serve as breakfast, brunch, or even a light dinner. Combining the earthiness of Brussels sprouts with the savory crunch of bacon creates a flavor profile that is both satisfying and unique.
This Roasted Brussels Sprouts and Bacon Quiche elevates the classic custard filling by incorporating roasted veggies, which add depth and complexity. The crispy bacon underscores the dish with its rich, smoky notes, making it a perfect centerpiece for any meal.
Ingredients
- 1 pre-made pie crust
The crust acts as the foundation of the quiche, providing a light and flaky texture that contrasts beautifully with the filling. Using a pre-made crust saves time without sacrificing quality. - 1 cup Brussels sprouts, halved
Brussels sprouts add a robust, slightly bitter flavor that mellows and caramelizes beautifully during roasting. They also contribute fiber and nutrients to the dish, enhancing its overall healthfulness. - 4 strips bacon, chopped
Bacon renders rich flavor and provides contrasting salty notes that balance out the earthy vegetables. The fat from the bacon also aids in creating a luscious quiche custard when combined with eggs and cream. - 4 large eggs
Eggs are the primary binding agent for the quiche, creating a creamy custard that holds all the ingredients together. They contribute protein and richness to the dish, ensuring each slice is satisfying. - 1 cup heavy cream
Heavy cream adds a luxurious texture and richness to the custard, ensuring the quiche has a smooth, creamy mouthfeel. It helps to enrich the flavor of the dish while creating a tender crumb. - 1 cup shredded Gruyère cheese
Gruyère cheese provides a mild, nutty flavor that melts beautifully, adding creaminess to the filling. Its excellent melting properties make it a perfect cheese choice for quiche. - Salt and pepper, to taste
Seasoning the quiche with salt and pepper elevates the flavors of the other ingredients. It helps to enhance the sweetness of the roasted Brussels sprouts and the savory notes of the bacon. - 1 tablespoon olive oil
Olive oil is used to toss the Brussels sprouts before roasting, helping them to brown evenly and develop a delicious caramelization. It also adds a subtle fruitiness to the overall dish.
Directions & Preparation
Step 1: Preheat your oven to 400°F (200°C).
Preheating the oven ensures that the quiche bakes evenly and that the crust achieves a golden, flaky texture. An accurately heated oven will produce a perfectly cooked custard without a soggy bottom.
Step 2: Toss the halved Brussels sprouts in olive oil, salt, and pepper, then spread them on a baking sheet.
Tossing the Brussels sprouts in oil with seasoning encourages even roasting. Evenly spacing them on a baking sheet allows hot air to circulate, ensuring they caramelize properly and develop rich flavors.
Step 3: Roast the Brussels sprouts for about 20-25 minutes, until they are golden brown and tender.
Roasting brings out the natural sweetness of the Brussels sprouts while adding a lovely char. Keep an eye on them to ensure they don’t burn; turning them halfway through will help achieve even browning.
Step 4: While the sprouts roast, cook the chopped bacon in a skillet over medium heat until crispy, then drain on paper towels.
Cooking the bacon until crispy not only renders flavorful fat but also adds a delightful crunch to the quiche. Draining on paper towels absorbs excess grease, preventing a greasy custard.
Step 5: In a large mixing bowl, whisk together the eggs and heavy cream until fully combined.
Whisking the eggs and cream together creates a smooth custard base. This step is crucial, as a well-emulsified mixture will ensure a creamy and cohesive filling without curdling.
Step 6: Stir in the roasted Brussels sprouts, crispy bacon, and half of the Gruyère cheese to the egg mixture.
Incorporating the roasted vegetables and bacon into the custard ensures every bite bursts with flavor. Mixing in half of the cheese will help the filling bind together while allowing the other half to melt on top for a delicious crust.
Step 7: Pour the filling into the pre-made pie crust, then sprinkle the remaining Gruyère cheese on top.
Pouring the filling into the crust requires a steady hand to prevent spilling. Sprinkling cheese on top will create a beautiful golden crust when baked, adding an appealing visual and flavor contrast.
Step 8: Bake for 30-35 minutes, or until the custard is set and the top is lightly golden.
Baking time is essential to ensure the custard is set without being overcooked. A slight jiggle in the center is normal; it will firm up as it cools. Ensure the top is golden for the best texture and appearance.
Step 9: Let the quiche cool for at least 10 minutes before slicing and serving.
Allowing the quiche to cool helps the custard to set fully, making it easier to slice and serve. This resting time enhances the flavors, allowing them to meld beautifully for a delicious meal.

The Importance of Roasting
Roasting Brussels sprouts brings out their inherent sweetness while imparting a satisfying crunch. This process caramelizes their natural sugars, resulting in a deeper flavor profile. This transformation is crucial to elevate the quiche’s taste, ensuring every bite bursts with complexity and richness.
Choosing the Right Cheese
Selecting Gruyère cheese enhances the quiche's overall flavor with its nutty, creamy notes. Its excellent melting properties lend a delightful texture, balancing the earthiness of the Brussels sprouts and the saltiness of the bacon. Experimenting with other cheeses, like cheddar or feta, can also yield delicious twists.
Perfect Pairings
This quiche pairs beautifully with a light salad or roasted vegetables, complementing the rich flavors of the dish. Consider a citrus vinaigrette to cut through the creaminess, or a simple arugula salad speckled with Parmesan for freshness, bringing a well-rounded dining experience.
FAQs
What should I do if the quiche filling is too runny?
If the filling is too runny, ensure that your egg-to-liquid ratio is correct, using a bit less cream. Additionally, baking it a little longer may help firm it up, but be cautious not to overbake.
Can I add extra vegetables to this quiche?
Absolutely! Feel free to add other roasted vegetables like bell peppers, zucchini, or spinach to mix up the flavor profile. Just be mindful of moisture content to avoid a soggy quiche.
What can I do if the top of my quiche isn’t browning?
If your quiche top isn't browning, consider increasing the oven temperature by 25 degrees Fahrenheit for the last few minutes of baking. You can also broil it briefly, watching closely to avoid burning.
Is there a way to enhance the flavor of this quiche?
Herbs such as thyme or chives can add a refreshing note to the quiche. Consider adding freshly cracked black pepper or a pinch of nutmeg to enhance the flavor even more.
Can I make this quiche without bacon?
Yes, you can easily omit the bacon or replace it with a smoked paprika for smokiness without meat. Alternatively, sautéed mushrooms or diced ham can also add great flavor.
What times of year is this quiche best for?
This quiche is particularly great for fall and winter when Brussels sprouts are in season. However, it's versatile enough to be enjoyed year-round, especially for brunch occasions.
