This 4-ingredient oven macaroni is the kind of no-fuss side dish I lean on during busy weeknights and Sunday dinners alike. You literally toss dry macaroni right into a metal roasting pan, add just three more everyday ingredients, and let the oven do the work. No boiling a separate pot of water, no fancy cheeses—just cozy, creamy, baked pasta that tastes like it took way more effort than it actually did. It’s very much a Midwestern-style, church-potluck kind of comfort food that has everyone scooping seconds straight from the pan.
Serve this oven macaroni alongside baked chicken, meatloaf, pork chops, or a simple ham for a classic family dinner. A crisp green salad or steamed broccoli balances the richness, and a pan of roasted vegetables shares the oven nicely if you’re already baking the pasta. It also makes a great base on the plate for saucy main dishes like barbecue pulled pork or smothered chicken. For casual nights, I’ll set the roasting pan on a trivet in the middle of the table with a bowl of peas or fruit salad and let everyone help themselves.
4-Ingredient Oven MacaroniServings: 6
Ingredients
2 cups dry elbow macaroni (uncooked)
3 cups whole milk
2 cups shredded cheddar cheese, divided
1 teaspoon kosher salt (plus more to taste)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a metal roasting pan (about 9x13 inches) with a little butter or nonstick spray so the pasta doesn’t stick.
Pour the dry elbow macaroni straight into the metal roasting pan and spread it into an even layer. This is your base—no boiling needed.
Sprinkle 1 1/2 cups of the shredded cheddar cheese evenly over the dry macaroni, making sure most of the pasta is touched by some cheese so it melts through the noodles as they cook.
In a large measuring cup or bowl, whisk together the whole milk and kosher salt until the salt is mostly dissolved. Taste the milk mixture and add a pinch more salt if needed, keeping in mind the cheese is salty too.
Slowly pour the milk mixture over the macaroni and cheese in the roasting pan. Gently shake the pan or stir lightly with a spoon to settle the pasta into the milk so most of the macaroni is submerged.
Cover the roasting pan tightly with aluminum foil, crimping the edges so steam stays in. Place the pan on the center rack of the preheated oven.
Bake, covered, for 30 minutes. Carefully remove the pan from the oven and peel back the foil away from you to avoid steam. Stir the pasta well, scraping the bottom of the pan to loosen any bits and to make sure the noodles are cooking evenly in the milk.
Sprinkle the remaining 1/2 cup shredded cheddar cheese evenly over the top of the macaroni. Leave the pan uncovered and return it to the oven.
Bake, uncovered, for another 15–20 minutes, or until the macaroni is tender, most of the liquid is absorbed into a creamy sauce, and the top is melted and lightly golden around the edges.
Let the macaroni rest in the pan for about 5–10 minutes before serving. This short rest helps the sauce thicken up and makes it easier to scoop neat servings for the table.
Variations & Tips
For extra flavor without adding more ingredients, use a sharp cheddar cheese and taste the milk mixture before pouring it over the pasta so you can adjust the salt. If you have picky eaters, you can blend mild and sharp cheddar, or swap in a milder cheese like Colby Jack for part of the cheddar to keep the flavor gentler. To stretch this for a crowd, add up to 1/2 cup more milk if the pasta seems dry when you stir halfway through baking—ovens and pans vary, and a little extra liquid can keep it creamy. For a slightly firmer, more casserole-like texture, bake on the longer end of the time range and let it rest a full 10 minutes before serving. If you’d like a bit of color, you can briefly broil the top at the very end, watching closely so the cheese doesn’t burn. Food safety tips: Use pasteurized milk and keep it refrigerated until you’re ready to assemble the dish. Don’t leave the baked macaroni out at room temperature for more than 2 hours; refrigerate leftovers promptly in shallow containers so they cool faster. Reheat leftovers to steaming hot (165°F/74°C) before serving, adding a splash of milk and covering the dish when reheating so the pasta doesn’t dry out.
