This 5-ingredient oven macaroni is the kind of cozy, no-fuss dish every busy family needs. You literally pour dry elbow macaroni straight into a clear glass casserole dish, add just four more everyday ingredients, and let the oven do the work. No boiling pasta, no fancy steps—just a creamy, cheesy bake that tastes like it simmered all afternoon. It’s the sort of Midwest-style comfort food I grew up with, and it’s exactly the kind of meal that has grandkids asking for seconds (and thirds) whenever they visit.
Serve this oven macaroni hot from the oven with a simple green salad or steamed broccoli to balance the richness. Garlic bread or buttered toast soldiers are great for scooping up the extra cheesy sauce. For a heartier spread, pair it with roasted chicken or meatloaf and a side of applesauce. It also works wonderfully as a holiday side dish next to ham or turkey, and the leftovers reheat nicely for next-day lunches with a handful of frozen peas or a side of sliced fruit.
5-Ingredient Oven MacaroniServings: 6
Ingredients
2 cups dry elbow macaroni
3 cups whole milk
2 cups shredded sharp cheddar cheese, divided
4 tablespoons unsalted butter, cut into small pieces
1 teaspoon kosher salt (plus more to taste)
Directions
Preheat your oven to 350°F (175°C). Place a clear 9x13-inch glass casserole dish on the counter. There’s no need to grease it—this recipe makes its own sauce as it bakes.
Pour the dry elbow macaroni straight into the glass casserole dish and spread it into an even layer. This should look like a loose blanket of pasta across the bottom of the dish.
Sprinkle 1 1/2 cups of the shredded sharp cheddar cheese evenly over the dry macaroni, saving the remaining 1/2 cup for the top later.
Dot the butter pieces all over the cheese and pasta so they’re scattered across the whole dish. This helps the sauce get rich and silky as it bakes.
Sprinkle the kosher salt evenly over everything in the dish.
Slowly pour the whole milk over the macaroni mixture, making sure to cover as much of the pasta as possible. Gently tap the dish on the counter to help the milk settle down into the noodles.
Cover the glass casserole dish tightly with aluminum foil, crimping the edges well so steam can’t easily escape. This step is important because it lets the macaroni cook through in the milk without drying out.
Bake, covered, for 45 minutes. About halfway through, carefully slide the rack out and give the mixture a gentle stir with a long spoon, making sure to reach the corners. Recover tightly and slide it back in to finish baking.
After 45 minutes, remove the foil and check a piece of pasta for doneness—it should be tender but not mushy. If it’s still a bit firm, stir, re-cover, and bake for another 10 minutes before checking again.
Once the macaroni is tender, remove the foil for good. Stir the mixture to bring some of the cheese and sauce from the bottom up to the top. Sprinkle the remaining 1/2 cup shredded cheddar evenly over the surface.
Return the uncovered dish to the oven and bake for 10–15 minutes more, or until the cheese on top is melted, bubbly, and lightly golden around the edges.
Remove from the oven and let the macaroni rest for 5–10 minutes before serving. This short rest helps the sauce thicken slightly so it’s creamy instead of runny when you scoop it. Serve warm, straight from the glass dish, and watch it disappear.
Variations & Tips
For extra flavor, you can stir in 1/2 teaspoon of black pepper or a pinch of garlic powder with the salt before baking. If your family likes things a little smoky, swap part of the cheddar for smoked cheddar or add a small handful of crumbled cooked bacon on top before the final bake (this does add ingredients beyond the basic 5-ingredient version, but it’s a fun twist). For picky eaters who prefer milder cheese, use half sharp cheddar and half mild cheddar or Colby Jack. If you need to stretch the recipe to feed more people, you can add up to 1/2 cup extra milk and a little more cheese, then bake a few minutes longer until the pasta is tender. To make it feel more like a full meal in one pan, stir in leftover diced ham or cooked chicken right after the first 45 minutes of baking, then finish as directed. For a slightly firmer texture, bake uncovered a bit longer at the end; for creamier macaroni, pull it from the oven as soon as the pasta is tender and the cheese is just melted. Food safety tips: Always use pasteurized milk and keep it refrigerated until you’re ready to assemble the dish. If you add cooked meats like bacon, ham, or chicken, make sure they’re fully cooked and cooled properly beforehand, and don’t leave the finished casserole out at room temperature for more than 2 hours. Refrigerate leftovers in a covered container and reheat thoroughly until steaming hot before serving again.
