Ingredients for bacon mac and cheese casserole
These rich, cheesy ingredients come together to create the ultimate comfort food masterpiece—crispy, creamy, and packed with smoky bacon goodness.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lb | Dry, medium elbow shape |
| Thick-Cut Bacon 🥓 | 1.2 lb | Smoked, cut into 1-inch pieces |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, block preferred |
| Monterey Jack Cheese 🧀 | 1 ½ cups | Shredded, mild flavor |
| Heavy Cream 🥛 | 1 cup | Full-fat for creaminess |
| Whole Milk 🥛 | 1 cup | Warmed for smooth sauce |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for topping |
| All-Purpose Flour 🌾 | ¼ cup | For roux, sifted |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Divided usage |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Garlic Powder 🧄 | ½ tsp | For depth of flavor |
| Onion Powder 🧅 | ½ tsp | For balanced seasoning |
| Panko Breadcrumbs 🍞 | ½ cup | For extra crunch |
The bacon is non-negotiable here—thick-cut smoked bacon gives that perfect smoky crunch. Costco or Trader Joe's have the best prices for bulk packs, and trust me, you'll use it all. For the cheese, block cheddar and Monterey Jack shred best—pre-shredded gets clumpy. The elbow macaroni should be medium size; those tiny ones disappear too fast. Pro tip: toast the pasta in the oven before adding cheese sauce for extra crispiness at the bottom layer.
No thick-cut bacon? Regular bacon cut into 1-inch pieces works, but it won't crisp as dramatically. Swapping cheddar? Gruyère or Gouda add depth, but stick with Monterey Jack for that classic melt. Short on breadcrumbs? Crushed potato chips (trust me on this) or even crushed Ritz crackers give that same satisfying crunch. The flour is just for the roux—don't skip it, or the sauce will be too thin. And if you're watching calories, use half-and-half instead of heavy cream—it still tastes amazing.
This casserole reheats beautifully—honestly tastes better the next day once everything melds. Keeps for 4-5 days in the fridge, freezes for 3 months. I always make a double batch because it disappears fast. For meal prep, portion into 8x8-inch baking dishes so you can reheat individual servings. The leftovers? Even better cold, perfect for quick lunches.

Step-by-step instructions for bacon mac and cheese casserole
This method delivers a perfect balance of creamy, cheesy goodness with a golden, crispy top and smoky bacon throughout.
Cook the Bacon and Prepare the Pasta
Preheat your oven to 375°F. Line a large baking sheet with parchment paper and arrange the 1.2 lb thick-cut bacon in a single layer. Bake for 20-25 minutes, flipping halfway, until the bacon is deep golden brown and crispy. Remove from oven and drain on paper towels, reserving ¼ cup of the bacon fat in the pan.
While the bacon cooks, bring a large pot of salted water to a boil and cook the 1.5 lb elbow macaroni according to package directions until al dente. Drain and set aside, reserving 1 cup of pasta water. The pasta should have a slight bite—it'll finish cooking in the oven.
Create the Creamy Cheese Sauce
In the same baking sheet (with reserved bacon fat), melt the 0.75 cup unsalted butter over medium heat. Whisk in the 0.25 cup all-purpose flour to form a roux, cooking for 2 minutes until golden and bubbly. Slowly pour in the 1 cup whole milk and 1 cup heavy cream, whisking constantly to prevent lumps.
Bring the mixture to a gentle simmer and cook for 3-5 minutes until it thickens slightly. Remove from heat and stir in the 2 cups sharp cheddar cheese and 1.5 cups monterey jack cheese until completely melted and smooth. Season with 1 tsp diamond crystal kosher salt, 0.5 tsp ground black pepper, 0.5 tsp garlic powder, and 0.5 tsp onion powder.
Combine and Assemble the Casserole
Add the cooked macaroni to the cheese sauce and toss gently to coat evenly. Fold in the crispy bacon, breaking it into 1-inch pieces as you go. The mixture should be thick but still pourable—if it's too stiff, add 2-3 tablespoons of reserved pasta water to loosen it.
Transfer the macaroni mixture to a 9x13-inch baking dish, spreading it evenly. The casserole should reach about ¾ of the way up the sides—this ensures room for the crispy topping without overflowing.
Create the Crispy Topping
In a small bowl, combine the 0.5 cup panko breadcrumbs with the remaining 0.5 tsp diamond crystal kosher salt. Sprinkle this mixture evenly over the top of the casserole, pressing down gently to adhere. Then, scatter the remaining 0.25 cup unsalted butter (cubed) over the breadcrumbs for extra richness and browning.
Return the casserole to the oven and bake for 25-30 minutes until the top is deep golden brown and the edges bubble slightly. The cheese should be fully melted and the breadcrumb topping should be crispy enough to crack under gentle pressure.
Rest and Serve
Remove the casserole from the oven and let it rest for 10 minutes before serving. This resting period allows the cheese to set slightly and makes it easier to cut clean slices. The internal temperature should reach 165°F—if it's not quite there, return to the oven for 5-10 minutes.
Serve with a side salad or steamed vegetables. The contrast of the crispy, cheesy casserole with fresh greens makes this dish even more satisfying. Each bite delivers smoky bacon, creamy cheese, and that perfect textural contrast from the crispy topping.
Pro Tips For Making Bacon Mac And Cheese Casserole
- Cook bacon low and slow: I used to blast that thick-cut bacon on high and end up with a greasy mess—now I cook it on medium-low for 12-15 minutes until crispy but not burnt. The extra time renders more fat without sacrificing flavor, which you’ll need for that rich, creamy sauce later.
- Dry the pasta well: Freshly drained elbow macaroni is a wet disaster in a casserole. Toss it with a spoonful of bacon fat or oil right after draining, then spread it on a baking sheet for 5 minutes. This prevents a soggy bottom and helps the cheese cling instead of pooling at the edges.
- Mix cheeses at room temp: Cold cheese clumps like a stubborn lump in your sauce. Take the cheddar and Monterey Jack out of the fridge 20 minutes before mixing—this ensures a smooth, velvety texture. If you’re in a rush, grate it yourself (pre-shredded has anti-caking agents that ruin the melt).
- Bake uncovered first: Covering the casserole too early traps steam and keeps the top damp. Start with 10 minutes uncovered at 375°F to brown the edges and crisp the bacon bits. Then foil it for the last 10-15 minutes to melt the cheese evenly—this two-step method guarantees a golden crust without a watery center.
Best sauces and condiments for this bacon mac and cheese casserole
Creamy Cheese Sauce
This velvety sauce is the heart of your casserole, and the secret lies in the roux. Cooking the 0.25 cup flour in ¼ cup reserved bacon fat until golden creates a rich base that prevents a grainy texture.
I always use Diamond Crystal kosher salt—it dissolves better than table salt and enhances flavor without overpowering. For extra depth, add a pinch of nutmeg (about ¼ tsp) to the sauce before baking—it adds warmth that complements the smoky bacon. 🧈
Smoky Bacon Enhancers
Take your bacon to the next level by adding 1 tsp smoked paprika to the pan while cooking. This amplifies the smokiness without altering the texture. For an extra kick, sprinkle 1 tbsp maple syrup over the bacon pieces before baking—the sweetness caramelizes beautifully.
I also like adding ½ tsp liquid smoke directly to the cheese sauce for an intense smoky flavor that pairs perfectly with the crispy topping. 🥓
Crispy Topping Variations
Swap the panko breadcrumbs for crushed potato chips (like Kettle Brand) for a salty, crunchy topping that's a crowd-pleaser. For a cheesy twist, mix ¼ cup grated Parmesan into the breadcrumbs before topping.
If you want extra richness, add 2 tbsp melted butter to the breadcrumb mixture for a golden, buttery crust. 🍞
Spicy Kick Options
Add heat with ½ tsp cayenne pepper or 1 tbsp hot sauce (like Frank's RedHot) to the cheese sauce. For a smoky-spicy combo, sprinkle 1 tsp chipotle powder over the casserole before baking.
If you love jalapeños, fold ½ cup diced pickled jalapeños into the cheese sauce—they add tangy heat that balances the richness. 🌶️
Extra Creamy Add-Ins
Boost the sauce with ½ cup sour cream or ¼ cup cream cheese for a thicker, tangier texture. For a decadent touch, stir in ½ cup cooked pulled pork or chicken sausage crumbles into the macaroni mixture.
If you love mushrooms, sauté 1 cup sliced cremini mushrooms in the bacon fat before making the roux—they add an earthy depth that pairs perfectly with the cheesy sauce. 🍄
Herbaceous Finishing Touches
Brighten the dish with fresh herbs like chopped chives or parsley sprinkled on top before serving. For a garlicky note, add 1 tsp minced fresh garlic to the cheese sauce.
If you're feeling fancy, drizzle with 1 tbsp white truffle oil after baking—it adds an umami richness that elevates the casserole to gourmet status. 🌿

Frequently asked questions
Can I make this casserole ahead of time?
This dish actually tastes even better the next day. Assemble the casserole up to 24 hours ahead and refrigerate uncovered. When ready to bake, cover with foil and bake at 375°F for 30-35 minutes (add 5-10 minutes if it's cold). For freezing, assemble completely, cover tightly with foil, and freeze for up to 3 months. Thaw overnight in the fridge before baking.
Why did my casserole get watery after baking?
This usually happens when too much pasta water is added or the cheese sauce wasn't thickened enough. The roux (butter + flour) is critical—cook it until golden brown for proper thickening. Also ensure your cheese is fully melted before assembling. If it happens, broil for 2-3 minutes at the end to evaporate excess moisture.
Can I use a different type of pasta?
Elbow macaroni works best because of its shape, but you can substitute with penne or fusilli. Avoid long pasta like spaghetti—it won't hold together well in the casserole. For a fun twist, try jewel pasta or star-shaped pasta, but reduce the baking time by 5 minutes to prevent overcooking.
How do I make the topping extra crispy?
For maximum crunch, broil the casserole for the last 2-3 minutes of baking. Spread the breadcrumb mixture evenly and press down firmly before baking. Another trick: mix 1 tbsp melted butter into the breadcrumbs before topping. If the top isn't crispy enough, return it to the broiler for 1-2 minutes after baking.
What's the best way to reheat leftovers?
Cover with foil and reheat at 350°F for 15-20 minutes until warmed through. For extra crispiness, broil for 1-2 minutes at the end. Microwave reheating works too—cover with a damp paper towel and heat in 30-second intervals, stirring between each, until hot. The texture won't be quite as crispy but still delicious!
