Slow Cooker Hobo Casserole: The Rustic, Hearty, Layer-It-and-Leave-It Dinner Your Family Will Love

 A hearty, no-fuss layered casserole with ground beef, potatoes, onions, and a creamy cheese topping. No pre-cooking required.

Prep & Cook Time

• Prep: 10 minutes

• Cook: Low 6–7 hours or High 3½–4 hours

• Serves: 6–8

Equipment

• 6-quart slow cooker

Ingredients

• Nonstick cooking spray or 1 tsp neutral oil (for greasing)

• 1½ lbs lean ground beef (90/10 recommended)

• 1 tsp kosher salt

• ½ tsp black pepper

• ½ tsp garlic powder (optional)

• 1 medium yellow onion, thinly sliced

• 4 medium russet potatoes, thinly sliced (about ⅛ inch thick)

• 1 can (10.5 oz) condensed cream of mushroom soup

• ¼ cup water

• 1 cup shredded sharp cheddar cheese

Optional toppings: chopped fresh parsley, sour cream, hot sauce

Instructions

1. Grease the slow cooker – Lightly coat the inside of a 6-quart slow cooker with nonstick spray or oil.

2. Add the beef – Spread the raw ground beef evenly over the bottom. Gently break it apart with a fork or your fingers (do not pack it down).

3. Season – Sprinkle the salt, pepper, and garlic powder evenly over the beef.

4. Layer the onions – Scatter the sliced onions over the beef.

5. Layer the potatoes – Arrange the potato slices over the onions, overlapping them slightly.

6. Make the sauce – In a small bowl, whisk together the cream of mushroom soup and water until smooth.

7. Add the sauce – Spoon the soup mixture evenly over the potatoes, covering as much surface as possible.

8. Slow cook – Cover and cook on LOW for 6–7 hours or HIGH for 3½–4 hours, until the potatoes are fork-tender and the beef is fully cooked.

9. Add cheese – Sprinkle the shredded cheddar over the top. Cover and let sit on WARM or LOW for 10–15 minutes until melted.

10. Rest and serve – Turn off the slow cooker. Let the casserole rest for 5 minutes before serving. Garnish with parsley, sour cream, or hot sauce if desired.

Pro Tips

• Thin, even potato slices – Use a mandoline or a sharp knife to get ⅛-inch slices so they cook evenly.

• Lean beef – 90/10 prevents excess grease. If using fattier beef, skim off any visible grease before adding the cheese.

Enjoy your rustic, hands-off dinner!
