Mac and Cheese with Brussels Sprouts & Bacon Breadcrumbs Ingredients
-
For the Pasta
Pasta (Conchiglioni) – This pasta shape holds the sauce beautifully; feel free to substitute with any large pasta like shells if needed. -
For the Vegetables
Brussels Sprouts – They add a slightly crunchy texture and earthy flavor; broccoli or spinach can be used for a delicious swap.
Kale – A nutritious addition that complements the richness; consider Swiss chard as an alternative.
Red Onions – These enhance the dish with caramelized sweetness; yellow onions work well, too.
Scallions – Provide a fresh touch; replace with chives or green onions if desired. -
For the Sauce
Butter – Essential for a luxurious cheese sauce; margarine is an option for a dairy-free version.
Flour – Acts as a thickening agent for the creamy sauce; cornstarch could be substituted.
Milk – Keeps the sauce silky and smooth; almond or oat milk can be used for a non-dairy twist.
Cheddar Cheese – The star ingredient; opt for a mix of cheeses like Gruyere or Monterey Jack for added flavor depth.
Garlic (optional) – Infuses the sauce with aromatic richness; fresh garlic is a great substitute for garlic powder. -
For the Flavor
Kosher Salt – Essential for enhancing flavors throughout the dish; any table salt will do.
Olive Oil – Ideal for sautéing vegetables; any vegetable oil can work in a pinch. -
For the Topping
Bacon – Adds richness and irresistible crunch; turkey bacon or leaving it out makes it vegetarian-friendly.
Chives (to garnish) – Provides a fresh pop of color and flavor; while optional, they are highly recommended for presentation.

Step‑by‑Step Instructions for Creamy Mac and Cheese with Brussels Sprouts & Bacon Breadcrumbs
Step 1: Render Bacon
In a Dutch oven, cook diced bacon over medium-low heat for about 20-25 minutes until crispy and golden, stirring occasionally to ensure even cooking. Once done, transfer the bacon to a paper towel-lined plate to drain excess fat, leaving the delicious drippings in the pot for extra flavor.
Step 2: Caramelize Onions
Using the same pot with the bacon fat, add sliced red onions over medium heat and cook for 5-6 minutes until they become tender and caramelized, scraping up the browned bits from the bottom. Stir in chopped scallions and a pinch of kosher salt, cooking for another minute until fragrant.
Step 3: Sauté Vegetables
Drizzle a bit of olive oil into the pot and add halved Brussels sprouts, sautéing them until they are browned and slightly tender, about 4-5 minutes. Add lemon zest and juice for brightness, then remove the Brussels sprouts, and repeat with chopped kale, cooking until just wilted, about 2-3 minutes.
Step 4: Prepare Breadcrumbs
In a food processor, process the cooked bacon along with some bread into coarse crumbs. Heat a small amount of olive oil in a skillet and fry the crumbs over medium heat for about 3-4 minutes until they are golden and crisp, then set aside for topping.
Step 5: Cook Pasta
Bring a large pot of salted water to a boil and cook conchiglioni pasta according to the package instructions, usually around 10-12 minutes, until al dente. Once cooked, drain the pasta and set it aside, reserving a bit of the pasta water for the cheese sauce if needed later.
Step 6: Make Cheese Sauce
In the same Dutch oven, melt butter over medium heat, then whisk in flour and cook for about 1-2 minutes until bubbly and lightly golden. Gradually add warm milk, continuously whisking until the mixture thickens, about 3-5 minutes, then reduce to low heat and stir in shredded cheddar cheese until smooth and creamy.
Step 7: Combine
Add the drained pasta along with the sautéed Brussels sprouts and kale to the cheese sauce, gently folding everything together. If the mixture is too thick, add a splash of reserved pasta water to reach your desired creamy consistency. Season with additional salt to taste.
Step 8: Serve
Dish out generous portions of the mac and cheese topped with the crispy bacon breadcrumbs and a sprinkle of fresh chives. The creamy mac and cheese with Brussels sprouts and bacon breadcrumbs is best enjoyed warm, inviting everyone to savor this delightful homely meal.

Make Ahead Options
These Creamy Mac and Cheese with Brussels Sprouts and Bacon Breadcrumbs are perfect for meal prep enthusiasts! You can cook the pasta and prepare the cheese sauce up to 24 hours in advance; simply store them separately in the refrigerator to maintain their best textures. Additionally, you can sauté the vegetables and combine them with the cheese sauce before refrigerating; just be sure to reheat gently on the stove, adding a splash of milk if needed to loosen the sauce. When ready to serve, simply combine everything, top with breadcrumbs, and bake as directed for a delicious, stress-free dinner that tastes just as delightful as when freshly made!

Mac and Cheese with Brussels Sprouts & Bacon Breadcrumbs Recipe FAQs
How do I choose ripe Brussels sprouts?
Look for Brussels sprouts that are firm, compact, and green with no dark spots or blemishes. The leaves should be tightly packed and feel heavy for their size. Avoid any that have wrinkly or yellowing leaves, as these indicate overripeness.
What is the best way to store leftover mac and cheese?
Store your mac and cheese with Brussels sprouts and bacon breadcrumbs in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F for 15-20 minutes or until heated through. Adding a splash of milk can help restore creaminess.
Can I freeze mac and cheese?
Absolutely! For freezing, let the mac and cheese cool completely before transferring to freezer-safe bags or containers. It can be frozen for up to 2 months. When ready to enjoy, thaw overnight in the fridge and reheat in the oven until hot and bubbly, usually around 25-30 minutes.
What if my cheese sauce is too thick?
If your cheese sauce has thickened too much before combining with the pasta, simply add a splash of reserved pasta water or more warm milk while stirring over low heat until you reach your desired consistency. Mixing gently will help incorporate the liquids without clumping.
Is there a vegetarian version of this recipe?
Yes! You can make this recipe vegetarian by omitting the bacon and using olive oil instead. For added flavor, consider using smoked paprika to mimic the smokiness of bacon, and feel free to experiment with different cheese combinations to keep it rich and satisfying.
Are there any common allergies to consider?
This recipe contains dairy and gluten (from the pasta and flour), so it may not be suitable for individuals with lactose intolerance or gluten sensitivities. To cater to these dietary needs, you can use gluten-free pasta, almond or oat milk, and non-dairy cheese alternatives while ensuring all ingredients used are gluten-free and vegan-friendly.
