This 4-ingredient slow cooker macaroni supper is the kind of back-pocket recipe you pull out on a busy weeknight when you want real comfort with almost no effort. Dry elbow macaroni goes straight into the crockpot—no boiling—and cooks gently in a simple trio of pantry staples: shelf-stable chicken broth, a can of evaporated milk, and a block of processed American cheese. It’s very much in the spirit of Midwestern church-supper casseroles and old-school hot dishes: humble ingredients, familiar flavors, and a creamy, kid-approved result that has a way of disappearing fast—especially when the grandkids are around.
Serve this slow cooker macaroni hot, straight from the crock, with a green side to balance the richness—think a simple tossed salad, steamed broccoli, or green beans. Garlic bread or warmed dinner rolls are great for swiping up the extra sauce. If you’d like a little contrast, offer a crunchy topping at the table, such as crushed crackers, toasted breadcrumbs, or crispy onions. A tangy side like coleslaw or sliced tomatoes with a drizzle of vinaigrette also helps cut through the creamy, cheesy pasta.
4-Ingredient Slow Cooker Macaroni SupperServings: 6
Ingredients
3 cups dry elbow macaroni (about 12 ounces)
4 cups low-sodium chicken broth
1 can (12 ounces) evaporated milk
1 pound processed American cheese, cut into 1-inch cubes
Directions
Lightly grease the inside of a 4- to 6-quart slow cooker with a bit of oil or nonstick spray to help prevent sticking.
Scatter the dry elbow macaroni evenly over the bottom of the slow cooker. The pasta should be in a fairly even layer, as in a process shot with the uncooked elbows and a pale yellow cheese block sitting together in the crock.
Place the block (or cubes) of processed American cheese on top of the dry macaroni, roughly in the center. It can sit as one large piece or several chunks; it will melt as it cooks.
Pour the chicken broth evenly over the macaroni and cheese, making sure all of the pasta is moistened. Then pour in the evaporated milk. Gently press down any macaroni that’s floating so most of it is submerged in the liquid.
Cover the slow cooker with the lid and cook on LOW for 1 1/2 to 2 1/2 hours, stirring every 30 minutes once you hit the 1-hour mark. Each time you stir, scrape along the bottom and sides to keep the pasta from sticking and to help the cheese melt smoothly into the sauce.
When the macaroni is tender but still holds its shape and the sauce is thick, creamy, and glossy, turn the slow cooker to WARM. If the mixture seems a bit loose, it will thicken slightly as it stands; if it seems too thick, stir in a splash of hot water or extra broth until it reaches your preferred consistency.
Taste and adjust the seasoning if you like (salt and pepper are optional and not counted among the core four ingredients). Serve the macaroni supper hot, straight from the slow cooker, and refrigerate any leftovers within 2 hours.
Variations & Tips
Because this recipe relies on just four pantry staples, small tweaks can make it feel new without adding much effort. For a smokier flavor, stir in a cup of diced cooked ham or crumbled cooked bacon during the last 20 minutes of cooking so the meat warms through without overcooking the pasta. To lean into a cheesier profile, you can swap part of the processed cheese (about 4 ounces) for shredded sharp cheddar; keep in mind that cheddar alone doesn’t melt as smoothly, so retaining some processed cheese helps maintain a velvety sauce. If you’d like a vegetarian version, use vegetable broth in place of chicken broth. For a bit of color and nutrition, fold in 1 to 2 cups of thawed frozen peas or mixed vegetables during the last 15 minutes of cooking.
Food safety and technique tips: Use low-sodium broth so you can better control the salt level; processed cheese already contains salt. Cut the cheese into smaller cubes if you want it to melt more quickly and evenly. Avoid cooking this on HIGH, as the pasta can overcook and become mushy or the sauce may curdle. Always keep the slow cooker covered except when stirring to maintain a safe temperature and even cooking. Once the macaroni is done, switch the cooker to WARM and serve within 1 to 2 hours; after that, cool leftovers promptly and refrigerate them within 2 hours of cooking. Reheat leftovers thoroughly to at least 165°F, adding a splash of milk or broth to loosen the sauce as needed.
