This oven-baked Amish-style beef and sweet corn casserole is the kind of practical comfort food that turns a handful of pantry staples and an economical cut of beef into a hearty family meal. Layering canned Mexicorn over raw petite sirloin lets the meat cook gently under a blanket of vegetables and creamy, savory ingredients, creating a dish that feels old-fashioned in the best way: simple, filling, and ideal for busy weeknights or relaxed summer suppers when you want something warm without a lot of fuss.
Serve this casserole with buttered egg noodles, mashed potatoes, or a basket of soft dinner rolls to catch the juices. For a lighter plate, pair it with sliced tomatoes, a crisp green salad, or steamed green beans. Because the casserole has sweet corn, beef, and a creamy topping, a tart side such as pickles or coleslaw also balances it nicely.
Oven-Baked 5-Ingredient Amish Beef and Sweet Corn Casserole
Servings: 4 to 6
Ingredients
1 1/2 pounds beef petite sirloin, cut into thin strips or bite-size pieces
Directions
1. Preheat the oven to 350°F. Lightly grease a 9x13-inch casserole dish. Spread the raw petite sirloin pieces in an even layer across the bottom of the dish.
2. Spoon the drained Mexicorn evenly over the beef, covering the surface as much as possible.
3. In a medium bowl, stir together the cream of mushroom soup and sour cream until smooth. Spread this mixture over the corn layer.
4. Sprinkle the shredded cheddar cheese evenly over the top. Cover the dish with foil and bake for 40 minutes. Uncover and bake 10 to 15 minutes more, or until the beef is cooked through and the top is hot and lightly golden.
5. Let the casserole rest for 10 minutes before serving so the layers can settle slightly. Spoon onto plates and serve hot.
Variations & Tips
Add onion: If you do not need to keep it strictly to five ingredients, add a thin layer of sliced onion over the beef before the Mexicorn. It gives the casserole a little more savoriness and softens beautifully as it bakes.
Use a different soup: Cream of chicken or cream of celery can stand in for cream of mushroom if that is what you have on hand. Each changes the flavor slightly, but all work well with the sweet corn and beef.
Slice the beef thinly: Petite sirloin benefits from being cut into thin strips or small bite-size pieces so it turns tender more easily in the casserole. Very thick chunks may need more baking time and can stay chewier.
Drain the corn well: Extra liquid from the Mexicorn can make the casserole too loose. Let it drain thoroughly before layering so the finished dish stays creamy rather than watery.
Make it sharper: For a bolder finish, use sharp cheddar instead of mild cheddar. The stronger cheese stands out nicely against the sweet corn and creamy sauce.
