This 5-ingredient Slow Cooker Amish Dog Days Casserole is the kind of practical summer supper that earns a regular place in the rotation: hearty, inexpensive, and easy to assemble without turning on the oven. Built around raw peeled sweet potato medallions, a creamy soup-based sauce, and a simple layer-and-cook method, it fits the old-fashioned “dog days” idea of making filling meals with minimal fuss while the slow cooker does the work through the hottest stretch of the season.
Serve this casserole with something crisp and fresh to balance its rich, soft texture, such as sliced cucumbers, tomato salad, coleslaw, or lightly dressed greens. If you want to round it out further, cornbread, buttered green beans, or a plate of simple pan-seared sausage or ham on the side all work well, and iced tea or lemonade makes it especially fitting for a midsummer dinner.
5-Ingredient Slow Cooker Amish Dog Days Casserole
Servings: 6
Ingredients
2 pounds sweet potatoes, peeled and sliced into 1/4-inch medallions
1 pound ground beef
1 small yellow onion, thinly sliced
1 can (10.5 ounces) condensed cream of mushroom soup
1 cup shredded sharp cheddar cheese
Directions
1. Lightly grease the slow cooker crock if desired. Spread a thin layer of sweet potato medallions on the bottom, then add a portion of the ground beef and sliced onion. Spoon over a little of the condensed soup, then repeat the layers until all ingredients are used, finishing with soup on top.
2. Cover and cook on LOW for 6 to 7 hours, or until the sweet potatoes are fully tender and the beef is cooked through.
3. Sprinkle the shredded cheddar cheese evenly over the top, cover again, and cook for 10 to 15 minutes more, just until the cheese is melted.
4. Let the casserole rest uncovered for 5 to 10 minutes before serving, then spoon onto plates or into shallow bowls.
Variations & Tips
Make it heartier: If you want a more substantial one-pot meal, add a second layer of beef by using up to 1 1/2 pounds total; just keep the sweet potato slices fairly thin so everything cooks evenly.
Swap the soup: Cream of chicken or cream of celery both work well here if that is what you have on hand, and each gives the casserole a slightly different savory background without changing the method.
Add seasoning carefully: Even though this is a very short ingredient list, a little black pepper, garlic powder, or paprika can be added if you like. Go lightly with salt at first, since condensed soup and cheddar already bring plenty.
Slice for even cooking: Try to keep the sweet potato medallions close to 1/4 inch thick. Thicker slices may stay too firm by the time the beef is fully cooked, while thinner slices can become overly soft.
Prevent excess liquid: If your beef releases a lot of moisture, use a leaner grind next time or briefly brown and drain it before layering. That adds a step, but it can give the finished casserole a thicker texture.
