Description

This Slow Cooker Steak and Cheddar Potato Casserole is a hearty, comforting dish layered with tender steak, cheesy potatoes, and rich seasonings—an easy, satisfying meal that’s perfect for busy days or cozy family dinners.


Ingredients

  • 1.52 lbs steak (sirloin or chuck), cut into bite-sized pieces
  • 45 medium potatoes (Yukon gold or russet), peeled and thinly sliced
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 2 cups shredded cheddar cheese, divided
  • ¾ cup sour cream or 4 oz cream cheese
  • ½ cup milk or heavy cream
  • 2 tablespoons butter, melted
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon paprika or smoked paprika
  • Optional garnishes: chopped green onions or parsley

Instructions

  1. Season the steak with salt, pepper, and paprika.

  2. Layer the ingredients in a greased slow cooker: half of the sliced potatoes, half of the onions, half of the steak, and 1 cup of cheddar. Repeat with remaining potatoes, onions, steak.

  3. In a bowl, mix sour cream (or cream cheese), milk, garlic, and melted butter until smooth. Pour the mixture over the layered ingredients.

  4. Cover and cook on low for 6–7 hours or high for 3–4 hours, until potatoes are tender and steak is cooked through.

  5. Add remaining cheddar in the last 15–20 minutes of cook time, cover until melted.

  6. Garnish and serve with green onions or parsley, if desired.


Notes

  • Searing the steak before slow cooking adds even more flavor but is optional.
  • Great with Monterey Jack or cheddar blends for a twist.
  • For added crunch, top with crispy fried onions just before serving.
  • Substitute frozen hash browns for a quicker prep.
