How to Make Loaded Bacon Mac and Cheese Bake Recipe
Step 1: Cook the Pasta
Start by cooking the elbow macaroni to al dente according to the package directions. This ensures your pasta is tender with a bit of bite so it doesn’t get mushy once baked. Drain it well and set aside because the pasta is the perfect base to soak up all that cheesy, savory sauce.
Step 2: Prepare the Bacon
While the pasta cooks, fry the bacon slices in a large cast-iron or oven-safe skillet until they turn crispy and golden. This step is key for that smoky crunch that makes this mac and cheese unforgettable. After frying, transfer the bacon to a plate lined with paper towels to drain the excess fat, then wipe out the skillet to make room for the sauce.
Step 3: Sauté Aromatics
Preheat your oven to 375°F. Next, melt 5 tablespoons of the butter in your clean skillet over medium heat. Add the minced onion along with a pinch of salt, then sauté until softened and fragrant, about two minutes. Stir in the garlic for another minute, allowing those savory aromas to awaken your senses.
Step 4: Make the Roux
Sprinkle the flour into the skillet and stir it into the butter-onion-garlic mixture until it forms a smooth, pasty texture. This roux is essential as it thickens the cheese sauce, giving it that luscious body you crave in a good mac and cheese.
Step 5: Create the Cheese Sauce
Now, slowly pour in the whole milk, whisking continuously over low to medium heat. This gradual incorporation prevents lumps and lets the sauce thicken beautifully. Once thickened, whisk in the sour cream to add a creamy tang that balances the richness perfectly.
Step 6: Add the Cheese
Remove the skillet from heat, then stir in 3 cups of the sharp cheddar cheese until it’s melted smoothly into a velvety sauce. This step is the magic moment where your mac and cheese starts taking shape.
Step 7: Combine Pasta and Bacon
Fold the cooked macaroni into the cheesy sauce, ensuring every noodle is luxuriously coated. Crumble half of the crispy bacon and stir it into this mixture to distribute that savory crunch within the creamy pasta.
Step 8: Prepare the Breadcrumb Topping
In a small separate pan, melt the remaining 3 tablespoons of butter over medium heat. Add the panko breadcrumbs and garlic salt, stirring until the crumbs turn golden and toasted. This golden topping will form that addictive crispy crust everyone loves.
Step 9: Assemble and Bake
Sprinkle the remaining bacon pieces and cheese over the macaroni in the skillet. Then, evenly spread the toasted breadcrumbs on top to create a crunchy, flavorful cap. Bake for about 15 minutes until the edges are bubbly and golden. For an extra crispy finish, broil for a few minutes but watch carefully to avoid burning. Let your Loaded Bacon Mac and Cheese Bake Recipe rest for 10 minutes before serving to allow it to set beautifully.
Step 10: Garnish and Enjoy
Just before serving, scatter chopped green onions or parsley over the top for a fresh burst of color and hint of freshness that perfectly balances the rich and smoky flavors.

Garnishes
A sprinkle of chopped green onion or parsley is the perfect fresh finish that brightens up this rich, indulgent casserole. It adds a lovely pop of green and a mild oniony note that complements the creamy cheese and smoky bacon.
Side Dishes
Since this mac and cheese bake is hearty on its own, consider pairing it with a crisp green salad tossed in a tangy vinaigrette or some roasted vegetables to add balance and freshness to the meal. Light, simple sides keep the focus on this indulgent star dish.
Creative Ways to Present
Try serving the mac and cheese in individual oven-safe ramekins for a charming and appealing presentation at gatherings. You can also sprinkle some extra bacon bits and a little cheese on top before reheating for a fresh, gooey crust each time.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftovers to an airtight container and refrigerate for up to 3 days. The flavors develop even more overnight, making for delicious next-day enjoyment.
Freezing
This Loaded Bacon Mac and Cheese Bake Recipe freezes well before baking. Assemble in a freezer-safe dish, cover tightly with foil, and freeze for up to 2 months. When ready, thaw overnight in the fridge before baking as directed.
Reheating
Reheat leftovers covered in the oven at 350°F until warmed through to preserve creaminess and avoid drying out. For a quick fix, microwave covered in short intervals, stirring in between to heat evenly.
FAQs
Can I use different types of pasta?
Absolutely! While elbow macaroni is classic, any short pasta shape like shells, cavatappi, or penne works wonderfully because they hold onto the cheesy sauce beautifully.
What if I don’t have sharp cheddar cheese?
You can substitute with other flavorful cheeses such as Monterey Jack, Colby, or a mix for a unique twist. Just ensure it’s a good melting cheese for the best creamy texture.
Is there a vegetarian version of this Loaded Bacon Mac and Cheese Bake Recipe?
Definitely! Simply omit the bacon and add crispy fried onions or smoked paprika for that smoky kick without the meat. You can also try using plant-based bacon alternatives.
Can I make this recipe gluten-free?
Yes, swap regular pasta with gluten-free pasta and use gluten-free flour and breadcrumbs to accommodate dietary needs while still enjoying this delicious bake.
How do I get the breadcrumb topping extra crispy?
To achieve maximum crunch, make sure to toast the breadcrumbs in butter until golden before sprinkling on top, and consider broiling the bake for a couple of minutes at the end to crisp the crust further.
