Description

A hearty, family-friendly casserole made in the slow cooker with layers of seasoned ground beef, tender potatoes, creamy mushroom sauce, and melted cheese. Perfect for busy weeknights or comforting weekend dinners.


Ingredients

Scale
  • 1 lb (450 g) ground beef (80/20 lean-to-fat ratio recommended)

  • 45 medium Yukon Gold or Russet potatoes, thinly sliced (about 1/8 inch)

  • 1 can (10.5 oz / 300 g) cream of mushroom soup

  • 1/2 cup (120 ml) milk or cream

  • 11 1/2 cups (120–180 g) shredded cheddar cheese (or Colby Jack/Mozzarella)

  • 1 small onion, finely chopped

  • 1 clove garlic, minced

  • Salt and pepper, to taste

  • Optional: chopped green beans, bell peppers, carrots, or peas for extra veggies

  • Optional: fresh parsley, chopped (for garnish)


Instructions

  • Brown the beef: In a skillet over medium heat, cook ground beef until browned. Add onion and garlic halfway through cooking. Season with salt and pepper. Drain excess fat.

  • Mix the sauce: In a medium bowl, whisk together cream of mushroom soup and milk until smooth.

  • Layer in slow cooker: Spray inside with nonstick spray. Arrange sliced potatoes on the bottom, then half the beef mixture, half the sauce, and a sprinkle of cheese. Repeat layers, ending with cheese.

  • Cook: Cover and cook on Low for 4–6 hours or High for 3–4 hours, until potatoes are fork-tender.

  • Serve: Garnish with fresh parsley if desired.

Notes

For richer flavor, use cream instead of milk.

Add cooked bacon on top before serving for extra flavor.

Pre-slice potatoes and brown beef in advance for easier prep.
