Make a rich, cheesy, and creamy scalloped potato and ham casserole using your slow cooker for simple preparation.

Ingredients

Scale
  • 3 lbs russet potatoes, peeled and thinly sliced
  • 1 lb fully cooked ham, diced
  • 1 medium onion, thinly sliced
  • 1 can (10.5 oz) condensed cream of chicken soup
  • 1 cup milk
  • 1 cup shredded sharp cheddar cheese, divided
  • 1/2 cup shredded smoked Gouda cheese
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon garlic powder
  • 2 tablespoons butter, melted

Instructions

  1. Lightly grease the inside of your slow cooker insert with cooking spray or butter.
  2. Arrange half of the sliced potatoes in an even layer in the bottom of the slow cooker.
  3. Sprinkle half of the diced ham and half of the sliced onion over the potatoes.
  4. In a separate bowl, whisk together the cream of chicken soup, milk, half of the cheddar cheese, the Gouda cheese, salt, pepper, and garlic powder until smooth.
  5. Pour half of the soup mixture evenly over the potato and ham layer.
  6. Repeat the layering process: remaining potatoes, remaining ham, remaining onion, and the rest of the soup mixture.
  7. Drizzle the melted butter over the top layer.
  8. Cover the slow cooker and cook on LOW for 6 to 7 hours or on HIGH for 3 to 4 hours, until the potatoes are tender when pierced with a fork.
  9. During the last 30 minutes of cooking, sprinkle the remaining cheddar cheese over the top. Replace the lid until the cheese is melted and bubbly.
  10. Carefully remove the insert from the slow cooker before serving.

Notes

  • For best results, slice potatoes uniformly thin, about 1/8 inch thick. A mandoline slicer works well for this.
  • If you do not have cream of chicken soup, you can substitute cream of mushroom soup.
  • This recipe works well for using up leftover holiday ham.
