This oven-baked Amish-style beef and lima bean casserole is the kind of practical, filling supper that turns a few pantry staples and an economical cut of beef into a comforting one-dish meal. Using condensed bean with bacon soup as the base creates a savory, creamy layer that keeps the flatiron steak moist as it bakes, while lima beans and a few simple seasonings give the dish the hearty, no-fuss character often associated with old-fashioned Midwestern and Amish home cooking.
Serve this casserole with buttered egg noodles, mashed potatoes, or thick slices of homemade bread to catch the rich sauce. A crisp green salad, steamed carrots, or simple coleslaw add welcome freshness alongside the creamy beans and beef, and for drinks, iced tea or a light lager both pair nicely with the casserole’s savory flavor.
Oven Baked 5-Ingredient Amish Beef and Lima Bean Casserole
Servings: 4 to 6
Ingredients
1 1/2 pounds beef flatiron steak
1 can (10 1/2 ounces) condensed bean with bacon soup
2 cups frozen lima beans
1 medium onion, thinly sliced
1/2 teaspoon black pepper
Directions
1. Preheat the oven to 350°F. Lightly grease a 9x13-inch baking dish. Lay the flatiron steak in the dish, trimming it if needed so it fits in an even layer.
2. Scatter the sliced onion and frozen lima beans evenly over and around the steak. Sprinkle with the black pepper.
3. Spoon the condensed bean with bacon soup over the top, then spread it gently to cover the beef and vegetables as evenly as possible.
4. Cover the dish tightly with foil and bake for 45 minutes. Remove the foil and continue baking for 20 to 25 minutes, or until the beef is cooked through and tender and the lima beans are fully hot.
5. Let the casserole rest for 5 to 10 minutes before slicing the steak and spooning the beans and sauce over each serving.
Variations & Tips
Add garlic: If you want a little more savory depth, add 1 to 2 minced garlic cloves under the soup layer before baking. It gives the casserole a fuller flavor without changing its simple character.
Use a different bean: If lima beans are not a favorite in your household, try green beans or a mix of peas and carrots. The texture will change slightly, but the casserole will still bake up nicely.
Slice after baking: Flatiron steak stays juicier when baked whole, then sliced for serving. Be sure to rest it briefly before cutting so the juices stay in the meat instead of running into the dish.
Make it creamier: For a looser, more spoonable casserole, stir 1/4 cup milk into the condensed soup before spreading it over the steak. This helps create more sauce for serving over potatoes or noodles.
Check tenderness: Because flatiron steak thickness can vary, start checking near the end of baking time. If the meat needs a little longer, cover it again and bake in 10-minute increments so it stays moist.
