This oven baked Amish-style garlic butter macaroni is the kind of simple casserole families fall in love with because it turns a handful of pantry staples into something rich, cozy, and deeply comforting. By layering uncooked elbow macaroni with jarred garlic butter sauce, liquid, and cheese right in the baking dish, you get an easy no-boil supper with an old-fashioned feel that fits right in with hearty Midwestern home cooking.
Serve this macaroni with a crisp green salad, buttered peas, roasted broccoli, or simple sliced tomatoes to balance the richness. It also pairs nicely with baked ham, rotisserie chicken, or meatloaf if you want to make it part of a bigger meal, though it is filling enough to stand on its own for a busy weeknight dinner.
Oven Baked 4-Ingredient Amish Garlic Butter Macaroni
Servings: 6
Ingredients
2 cups uncooked elbow macaroni
1 jar garlic butter sauce, about 12 to 16 ounces
2 cups whole milk
2 cups shredded mozzarella or mild cheddar cheese
Directions
1. Preheat the oven to 375°F and lightly grease a 9x13-inch casserole dish.
2. Add the uncooked elbow macaroni to the prepared casserole dish and spread it into an even layer.
3. Spoon the jarred garlic butter sauce all over the macaroni, then pour in the milk and stir gently so the pasta is coated and evenly distributed.
4. Sprinkle the shredded cheese evenly over the top. Cover the dish tightly with foil.
5. Bake for 30 minutes, then uncover and bake for 10 to 15 minutes more, until the pasta is tender and the top is hot, bubbly, and lightly golden.
6. Let the casserole rest for 5 to 10 minutes before serving so the sauce can settle and the macaroni turns extra creamy.
Variations & Tips
For a sharper flavor: Swap the mozzarella for sharp cheddar, Colby jack, or a mix of Parmesan and cheddar if your family likes a bolder cheesy bite.
For picky eaters: Keep the recipe just as written for the mildest flavor, or use a creamy garlic parmesan sauce if the jarred garlic butter sauce you have seems too strong.
For a heartier casserole: Stir in 1 to 2 cups of diced cooked chicken, ham, or crumbled cooked bacon before baking to turn this into a full one-pan dinner.
Baking tip: If the pasta still seems a little firm when you uncover it, add a small splash of milk, cover again, and bake a few minutes longer. Different brands of pasta and sauce can absorb liquid a little differently.
Make-ahead note: Assemble the dish a few hours ahead, cover, and refrigerate. When ready to bake, let it sit at room temperature for about 20 minutes first so it bakes more evenly.
