This oven baked Amish-style beef and cream of potato bake is the kind of simple supper that earns a regular spot in the meal rotation. With just four ingredients, it turns petite sirloin into a cozy, fork-tender main dish with a rich, creamy topping that feels hearty and familiar. Recipes like this are popular in home-style Midwestern cooking because they rely on pantry staples, easy prep, and slow oven baking to create a comforting dinner without much fuss.

Serve this bake with buttered egg noodles, mashed potatoes, or steamed rice to catch every bit of the creamy sauce. For vegetables, green beans, buttered corn, peas, or a simple side salad all work nicely, and a basket of warm dinner rolls makes it feel especially comforting for a family meal.

Ingredients

1 1/2 to 2 pounds beef petite sirloin steak

1 can (10.5 ounces) cream of potato soup
1 medium onion, thinly sliced
1 packet onion soup mix

Directions

1. Preheat the oven to 325°F and lightly grease a medium casserole dish. Lay the petite sirloin steak in the dish in an even layer, trimming or cutting the meat into large serving pieces if needed so it fits well.

2. Spread the cream of potato soup evenly over the top of the beef, then scatter the sliced onion over the soup.

3. Sprinkle the onion soup mix evenly over everything. Cover the casserole dish tightly with foil.

4. Bake for 1 hour 45 minutes to 2 hours, or until the beef is tender and the onions are very soft. Carefully uncover the dish for the last 10 to 15 minutes if you would like the top to thicken a little more.

5. Let the bake rest for 5 to 10 minutes before serving. Spoon the sauce over the beef and serve hot with your favorite side dishes.

Variations & Tips

For extra flavor: If your family enjoys a little more seasoning, add a light sprinkle of black pepper or garlic powder before baking. Since the soup and onion soup mix are already salty, taste the finished sauce before adding any extra salt.

For picky eaters: If sliced onions are a tough sell at your table, chop them very finely so they melt more into the sauce as the dish bakes. You still get the flavor, but the texture is much gentler.

Make it over potatoes: For an even heartier one-dish meal, place a layer of thinly sliced potatoes under the beef before adding the soup and onions. If you do this, plan on extra baking time and check that the potatoes are fully tender before serving.

Choose the right cut: Petite sirloin works well here because it becomes tender with a slow bake, but you can also use round steak or cubed steak if that is what you have on hand. Just keep the pieces in a single layer so they cook evenly and stay nicely coated in the sauce.
