This oven-baked Amish-style beef and green bean casserole is the kind of practical, filling supper that suits a busy weeknight and still feels like comfort food. Built from just a handful of pantry and refrigerator staples, it relies on simple layering rather than complicated prep, with tender beef petite tender on the bottom and canned french style green beans and a creamy topping baked over it. The result is a hearty casserole with old-fashioned appeal and the sort of straightforward flavor that keeps family-style recipes in regular rotation.
Serve this casserole with buttered egg noodles, mashed potatoes, or a piece of warm bread to catch the creamy sauce. A crisp side salad with a tart vinaigrette or some sliced fresh tomatoes works especially well alongside it, since a fresh, bright side balances the richness of the beef and baked topping.
Oven Baked 5-Ingredient Amish Beef and Green Bean Casserole
Servings: 6
Ingredients
1 1/2 to 2 pounds beef petite tender
Directions
1. Preheat the oven to 350°F and lightly grease a 9x13-inch casserole dish. Pat the beef petite tender dry, then place it in the dish in an even layer. If the tender is very thick, slice it into thick strips or medallions so it cooks more evenly under the topping.
2. Spread the drained french style green beans evenly over the beef, covering it from edge to edge.
3. In a bowl, whisk together the condensed cream of mushroom soup and milk until smooth. Pour the mixture over the green beans, then sprinkle the French fried onions over the top.
4. Cover the dish tightly with foil and bake for 45 minutes. Remove the foil and continue baking for 15 to 20 minutes more, until the beef is cooked through, the casserole is bubbling, and the onions on top are golden.
5. Let the casserole rest for 10 minutes before serving so the juices settle and the creamy topping thickens slightly. Spoon onto plates and serve hot.
Variations & Tips
Add cheese: For a richer casserole, sprinkle 1 cup shredded cheddar or mozzarella over the soup layer during the last 15 minutes of baking. It is not traditional, but it gives the top an extra savory finish.
Use a different soup: Cream of chicken or cream of celery both work well here if that is what you have in the pantry. Each one changes the flavor slightly while keeping the same creamy texture.
Check doneness carefully: Because beef petite tender can vary in thickness, use a meat thermometer if needed. You want the beef fully cooked and tender enough to slice easily after resting.
Make the topping crispier: If you like the fried onions very crunchy, add half before baking and the remaining half after uncovering the casserole. That keeps part of the topping from softening too much under the steam.
Drain the beans well: This is one of the most important details in the recipe. Extra liquid from the canned green beans can thin the sauce too much, so let them drain thoroughly before layering.
