Ingredients You’ll Need
This recipe relies on simple, familiar ingredients, each adding a necessary touch — creamy richness, cheesy pull, savory crunch, or a hint of sweetness. Don’t be tempted to skip or swap; each one is there for a reason and together, they make this dish downright irresistible.
- 1 (7.25-ounce) box macaroni and cheese: The backbone of our casserole; choose your favorite boxed variety for reliable creaminess and perfect noodles.
- 1 (15-ounce) can whole kernel corn, drained: Adds pops of sweetness and golden color that balance out all the savory notes beautifully.
- 1 (15-ounce) can cream-style corn: This brings extra creaminess and depth, blending right into the cheesy sauce for a dreamy texture.
- 1/2 cup sour cream: Provides tang and silkiness, tying all the flavors together in luscious harmony.
- 1/2 cup milk: Loosens everything up so your casserole is moist without being too runny or dry.
- 1/4 cup unsalted butter, melted: For that buttery touch that makes every bite extra indulgent—using unsalted lets you control the seasoning.
- 1 1/2 cups shredded cheddar cheese: The ooey-gooey cheese factor; sharp cheddar is best here for bold flavor and lovely melt.
- 6 slices cooked bacon, crumbled: A generous dose of smokiness, crunch, and savory goodness—don’t skimp if you love bacon!
- 1/4 cup chopped green onions: Fresh, mildly zippy, and the perfect pop of color for both filling and garnish.
- Salt and black pepper to taste: Don’t forget to season; it elevates all the other ingredients and sharpens the overall flavor.
How to Make Loaded Mac & Cheese Corn Casserole Recipe
Step 1: Prepare the Macaroni and Cheese
Start by preheating your oven to 350°F so it’s ready when you are. Cook the boxed macaroni and cheese according to the package directions. That means boiling the noodles, draining them, then mixing in the cheese powder (plus any butter and milk the box calls for) until everything is perfectly creamy. Set aside to cool slightly.
Step 2: Mix the Fillings Together
Grab your biggest mixing bowl. To the prepared mac and cheese, add the drained whole kernel corn, cream-style corn, sour cream, milk, melted butter, 1 cup of shredded cheddar, half the crumbled bacon, and half the green onions. Sprinkle in salt and black pepper to taste, then mix everything together really well so every bite will be loaded with flavor and texture.
Step 3: Assemble and Top
Lightly grease a 9×13-inch baking dish (a quick brush with butter or spray is perfect). Pour in your mac and cheese-corn mixture, smoothing it out into an even layer. Sprinkle the remaining 1/2 cup of cheddar cheese over the top, followed by the leftover bacon crumbles. This is where things start looking irresistible!
Step 4: Bake Until Bubbly
Pop the casserole into your preheated oven and bake uncovered for 30 to 35 minutes. You’re looking for that iconic golden color on top and gently bubbling cheese around the edges—this is when you know all those flavors have melded perfectly together.
Step 5: Garnish and Serve
Once the Loaded Mac & Cheese Corn Casserole Recipe comes out of the oven, let it rest for about five minutes to firm up a bit. Then sprinkle on the remaining green onions for a fresh finish, slice, and serve up big, satisfying scoops to everyone around your table.
How to Serve Loaded Mac & Cheese Corn Casserole Recipe

Garnishes
There’s something magical about a pretty casserole! Right before serving, scatter a handful of extra green onions for that fresh bite and inviting pop of color. If you like a little heat, try thinly sliced jalapeños or a dusting of smoked paprika over the top. For those who love decadence, a light drizzle of ranch dressing or a sprinkle of crispy fried onions can make this dish extra special.
Side Dishes
This casserole goes hand in hand with many classic sides. Serve it alongside tangy coleslaw, roasted veggies, or a crisp green salad to balance out the richness. For heartier occasions, pair it with glazed ham, pulled pork, or griddled sausages. The Loaded Mac & Cheese Corn Casserole Recipe shines as both a sidekick and the star of your meal.
Creative Ways to Present
Try baking the casserole in individual ramekins for personal-sized servings—perfect for dinner parties or potlucks. Or, scoop it into hollowed mini bell peppers for a colorful appetizer tray. If you’re feeling playful, serve it “bar-style” with bowls of toppings like jalapeños, extra cheese, and crushed tortilla chips so everyone can customize their own slice.
Make Ahead and Storage
Storing Leftovers
To save any extras, let your casserole cool completely, then transfer leftovers to airtight containers. Stored in the fridge, it stays creamy and delicious for up to 4 days. The flavors only get better overnight, making it a satisfying lunchbox treat or next-day snack.
Freezing
Want to prep ahead of time? This Loaded Mac & Cheese Corn Casserole Recipe freezes beautifully! Bake, cool, and wrap tightly in plastic wrap and foil (or use freezer-friendly containers). It’ll keep well for up to 2 months—just remember to label with the date.
Reheating
Reheat individual portions in the microwave until hot, stirring halfway through to ensure even warming. For bigger batches or a just-thawed casserole, cover with foil and warm in a 350°F oven for 20 minutes or until heated through. If it looks a little dry, add a splash of milk before reheating to restore creaminess.
