This oven baked Amish green bean macaroni is the kind of practical casserole-style supper that earns a permanent spot in a busy weeknight rotation. It uses just four simple ingredients, goes straight into one glass baking dish, and comes together with almost no prep beyond snapping green beans and opening a can. Dishes like this are rooted in old-fashioned home cooking, where pantry staples and garden vegetables were stretched into filling family meals, and it still works beautifully when you need something easy without making another trip to the store.
Serve this warm with sliced tomatoes, buttered bread, applesauce, or a simple cucumber salad for an easy summer meal. If you want to round it out a little more, baked ham, sausage, or shredded rotisserie chicken pair nicely on the side, but it is also satisfying as a humble meatless main dish.
Oven Baked 4-Ingredient Amish Green Bean Macaroni
Servings: 6
Ingredients
2 cups dry elbow macaroni
1 pound fresh green beans, snapped into 1 to 2 inch pieces
1 can (10 3/4 ounces) condensed tomato soup
2 soup cans water
Directions
1. Preheat the oven to 350°F and lightly grease a 9x13-inch glass baking dish.
2. Spread the dry elbow macaroni evenly in the prepared baking dish, then scatter the snapped green beans over the top.
3. In a bowl or large measuring cup, whisk together the condensed tomato soup and 2 cans of water until smooth.
4. Pour the soup mixture evenly over the macaroni and green beans, making sure the pasta is mostly submerged.
5. Cover the dish tightly with foil and bake for 45 minutes. Remove the foil, stir gently, then bake 15 to 20 minutes more, or until the macaroni is tender and most of the liquid is absorbed.
6. Let the dish rest for 5 to 10 minutes before serving so the sauce can settle and the texture can finish softening.
Variations & Tips
Add onion: If you want a little more flavor without changing the spirit of the recipe, add about 1/2 cup finely chopped onion over the macaroni before baking. It softens nicely in the dish and gives the casserole a sweeter, fuller taste.
Use canned or frozen green beans: Fresh is classic, but drained canned green beans or thawed frozen green beans can work in a pinch. If using canned, reduce the baking time slightly since they are already soft.
Make it creamier: For a softer, richer texture, replace part of the water with milk. This helps create a more casserole-like finish and is especially nice if you prefer your baked macaroni less brothy.
Check for doneness before serving: Since oven temperatures and pasta brands vary, test a piece of macaroni before pulling the dish out for good. If it still seems too firm, add a splash of hot water, cover again, and bake a little longer.
Meal-prep tip: I like to snap the green beans earlier in the day and keep them in the fridge, so dinner feels almost effortless at night. This is exactly the kind of back-pocket recipe that saves me when I am tired, low on groceries, and still want something warm and homemade.
