Spoon garlic butter sauce and these 3 ingredients over elbow macaroni into a baking dish for an effortless meal that becomes an instant classic

This oven-baked 4-ingredient Amish-style garlic butter macaroni is one of those “busy weeknight but still want real comfort food” recipes. Think of it as a shortcut version of a church potluck classic: you dump uncooked elbow macaroni into a baking dish, spoon over a generous layer of store-bought garlic butter sauce, add just three more simple ingredients, and let the oven do the work. No boiling pasta, no complicated roux—just a cozy, buttery, garlicky pan of noodles that tastes like it took all afternoon.

Serve this garlic butter macaroni straight from the baking dish with a big green salad or steamed broccoli to balance the richness. Garlic bread or warm dinner rolls are great for soaking up the buttery sauce, and a simple grilled or rotisserie chicken on the side turns it into a full, family-friendly meal. If you’re entertaining, pair it with roasted vegetables and a crisp white wine or sparkling water with lemon to keep things light and fresh.

Servings: 6

2 cups uncooked elbow macaroni (about 8 oz)

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with cooking spray or a thin swipe of butter to help prevent sticking.

Pour the uncooked elbow macaroni evenly into the bottom of the prepared baking dish. Shake the dish gently to level the pasta so it cooks evenly.

In a medium bowl or large measuring cup, whisk together the jarred garlic butter sauce and the whole milk until the mixture is smooth and well combined. This creates a pourable garlic butter sauce that will soak into the pasta as it bakes.

Spoon the garlic butter and milk mixture evenly over the uncooked elbow macaroni in the baking dish, making sure to cover as much of the pasta as you can. Use the back of the spoon to nudge the sauce into the corners and down between the noodles so everything gets coated.

Sprinkle 1 cup of the shredded cheddar cheese evenly over the sauced macaroni. Reserve the remaining 1/2 cup of cheese for topping later.

Cover the baking dish tightly with aluminum foil to trap the steam. This helps the elbow macaroni cook through in the oven without boiling it first.

Bake the covered dish on the middle rack for 35–40 minutes, or until the pasta is mostly tender when you poke a piece with a fork and the sauce is bubbling around the edges.

Carefully remove the foil (watch for steam), then sprinkle the remaining 1/2 cup shredded cheddar cheese evenly over the top of the macaroni.

Return the uncovered dish to the oven and bake for another 10–15 minutes, or until the cheese on top is melted, lightly golden in spots, and the pasta is fully tender.

Let the garlic butter macaroni rest for 5–10 minutes before serving. This helps the sauce thicken slightly so it’s creamy instead of runny. Spoon into bowls and enjoy warm.

For extra richness, replace 1/2 cup of the milk with heavy cream or half-and-half. If you like more of a cheesy pull, swap part of the cheddar for mozzarella or Monterey Jack. To lean into the Amish-style comfort food vibe, you can stir in 1 cup of diced ham or cooked shredded chicken after the initial covered bake, then top with cheese and finish baking. For a little texture, sprinkle 1/2 cup buttered breadcrumbs or crushed butter crackers over the top along with the final layer of cheese. If you prefer a lighter version, use 2% milk and a reduced-fat cheese, understanding the sauce will be slightly less creamy. You can also add a handful of frozen peas or small broccoli florets under the cheese layer for a one-pan meal; just keep the dish covered an extra 5 minutes if the veggies are still quite cold. Food safety tips: Make sure any add-ins like ham or chicken are fully cooked and kept refrigerated until you mix them in. If you’re reheating leftovers, heat them to at least 165°F (74°C) and store leftovers in a shallow, covered container in the refrigerator within 2 hours of baking. Because this recipe uses milk and cheese, don’t leave the finished dish out at room temperature for more than 2 hours.
