Ingredients You’ll Need
The beauty of this dish comes from a handful of simple, familiar ingredients, each playing a crucial role in creating that signature taste and texture. From gooey cheese to crispy bacon and bright scallions, every ingredient is there for a reason—don’t skip a thing!
- Short pasta (8 ounces): Elbow macaroni, shells, or rotini all work beautifully to capture that rich, velvety sauce.
- Unsalted butter (6 tablespoons, divided): Adds creaminess to the sauce and helps give the breadcrumb topping its golden crunch.
- All-purpose flour (5 tablespoons): Essential for thickening the cheese sauce to the perfect consistency.
- Whole milk (3 cups, warmed): Warming the milk helps the sauce come together smoothly and keeps it extra luscious.
- Shredded sharp cheddar cheese (2 cups): The backbone of that classic mac and cheese flavor, sharp cheddar brings a punchy tang.
- Shredded Swiss cheese (1 cup): Swiss adds a mellow, nutty note that pairs perfectly with the cheddar.
- Dry ground mustard (½ teaspoon): Just a touch brightens the cheese and deepens the overall flavor.
- Garlic (1 clove, pressed): Fresh garlic gives the sauce a subtle savory boost.
- Cayenne pepper (¼ teaspoon): For a gentle kick of heat that lingers just enough.
- Paprika (½ teaspoon): Adds warmth and a lovely golden color.
- White pepper (pinch): A little goes a long way for subtle, earthy spice.
- Salt (½ teaspoon): Brings all the flavors together—taste and adjust if needed!
- Black pepper (to taste): Freshly cracked is best for a bold finish.
- Frozen corn (2 cups): The sweet pops of corn add unexpected bursts of flavor and color.
- Bacon (6 slices, cooked and crumbled): Smoky, salty bacon is the ultimate finishing touch for richness and crunch.
- Scallions (5, chopped and divided): Half go in the sauce for freshness, half on top for color and zing.
- Seasoned breadcrumbs (½ cup): They form a perfectly crispy, flavorful crust when baked.
How to Make Loaded Mac & Cheese Corn Casserole Recipe
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil and cook your choice of short pasta until just al dente. You want the noodles to have a little bite—they’ll absorb some of the sauce in the oven and finish cooking there. Once done, drain the pasta and set it aside. This step sets the stage for all the flavor to come!
Step 2: Make the Cheese Sauce
While the pasta cooks, start building the heart of this Loaded Mac & Cheese Corn Casserole Recipe: the cheese sauce. In a large skillet, melt 3 tablespoons of butter over medium-low heat. Sprinkle in the flour and whisk constantly for a minute or two, letting it bubble and thicken to a light golden color. Slowly pour in the warmed milk, whisking all the while to prevent lumps. Continue stirring until the sauce thickens, then remove from heat and stir in the cheddar, Swiss, mustard, pressed garlic, cayenne, paprika, white pepper, salt, and black pepper. Once everything is melty and gorgeous, fold in the crumbled bacon, half the scallions, and all the frozen corn. This is where it all comes together—creamy, cheesy, and loaded with flavor.
Step 3: Assemble the Casserole
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish. Pour the cooked pasta into the dish, then drizzle that glorious cheese sauce over the top. Gently stir it all together, making sure every noodle gets coated and the corn and bacon are evenly distributed. Every bite should be loaded with goodness!
Step 4: Make the Breadcrumb Topping
Melt the remaining 3 tablespoons of butter in a small bowl. Add the seasoned breadcrumbs and the rest of the chopped scallions, tossing until everything is well combined. Sprinkle this mixture evenly over the casserole. It bakes up into a ridiculously tempting golden crust that’s impossible to resist.
Step 5: Bake and Broil
Bake the casserole for 20 minutes, letting the flavors meld and the top start to crisp. For the final flourish, switch your oven to low broil and let it go for 3-5 minutes—just until the topping turns golden brown and crunchy. Keep a close eye so it doesn’t burn! Let it rest for 5-10 minutes before diving in; this helps everything set up for perfect slices.
How to Serve Loaded Mac & Cheese Corn Casserole Recipe

Garnishes
A sprinkle of fresh scallions or chopped parsley adds a touch of color and a pop of freshness to each serving. You can also dust a little extra paprika or even a bit more crispy bacon on top for an irresistible presentation—don’t be shy!
Side Dishes

Make Ahead and Storage
Storing Leftovers

Freezing
If you want to freeze the casserole, let it cool completely, then wrap tightly with foil or transfer to a freezer-safe dish. It can be frozen for up to 2 months. Thaw overnight in the fridge before reheating to maintain the best texture.
Reheating
To reheat, cover the casserole with foil and warm in a 350°F (175°C) oven for 20–25 minutes, or until heated through. For a crispier topping, remove the foil for the last few minutes. Individual portions can be microwaved, but the oven helps retain that lovely crispy top.
FAQs
Can I make the Loaded Mac & Cheese Corn Casserole Recipe ahead of time?
Absolutely! You can assemble the casserole a day in advance, cover tightly, and refrigerate. Just add a few extra minutes to the baking time when ready to serve.
