How to Make Mac and Cheese with Brussels Sprouts & Bacon Breadcrumbs

  1. Cook Bacon: In a Dutch oven, render bacon over medium heat until crispy, about 20-25 minutes. Once perfectly golden, remove the bacon and reserve the fat for added flavor in your dish.

  2. Caramelize Onions: In the reserved bacon fat, cook the red onions until they become tender and caramelized, about 5-6 minutes, and then add the scallions. Cook for an additional minute before setting aside.

  3. Cook Vegetables: In the same pot, add a splash of olive oil and saut the Brussels sprouts until they re nicely browned, stirring in lemon juice for brightness. Quickly wilt the kale and set it aside with the other veggies.

  4. Prepare Breadcrumbs: Pulse your bread and cooked bacon together in a food processor until crumbly. Then, pan-fry this mixture in olive oil until golden and crisp, seasoning as desired, and reserve for topping.

  5. Cook Pasta: Boil the conchiglioni pasta in salted water for 1 minute less than package instructions indicate. Drain and set aside, ready to embrace the sauce.

  6. Make Sauce: Melt the butter in a saucepan, add the flour, and whisk until combined. Gradually add the heated milk, stirring until the sauce thickens, then stir in shredded cheddar until smooth.

  7. Combine: Gently fold the cooked pasta and caramelized veggies into the cheesy sauce, stirring to coat everything evenly. Don t forget to season to your liking!

  8. Serve: Spoon generous portions onto dishes and top with crispy bacon breadcrumbs and a sprinkle of fresh chives for an inviting finish.

What s the best way to store leftovers?
For optimal freshness, store your mac and cheese in an airtight container in the fridge for up to 3 days. I recommend allowing it to cool completely before sealing, which helps lock in flavor. When reheating, do so gently in the oven to maintain the creamy texture.

What should I do if my cheese sauce turns lumpy?
The key to a smooth cheese sauce is to whisk it well as you add the cheese. If it does become lumpy, don t fret! You can use an immersion blender to smooth it out. Alternatively, let it cool slightly and then whisk vigorously or blend it until smooth; just be cautious with the heat to prevent the cheese from separating.

Are there any dietary considerations for this recipe?

For a gluten-free version, use gluten-free pasta and flour. Always check labels of your cheese and other ingredients to avoid allergens.
