No reviews

A comforting, one-dish dinner with layers of tender potatoes, savory sausage, onions, and melted cheese—effortlessly made in the slow cooker and finished under the broiler for a golden crust.

  • Total Time: 4 hours 15 minutes
  • Yield: 6 servings 1x

Ingredients

Scale
  • 2 lbs Yukon Gold potatoes, sliced 1/4 inch thick
  • 12 oz Italian sausage (mild or spicy), sliced 1/4 inch thick
  • 1 large yellow onion, thinly sliced
  • 2 cups shredded sharp cheddar cheese
  • 1/2 cup heavy cream or half-and-half
  • 1 tsp garlic powder
  • 1 tsp paprika
  • 1/2 tsp black pepper
  • 1/4 tsp salt (optional)
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Lightly grease the inside of a 6-quart slow cooker.
  2. Layer half the potato slices, followed by half the sausage, half the onions, and 1/2 cup cheese. Repeat layers.
  3. In a small bowl, whisk together cream, garlic powder, paprika, pepper, and salt (if using). Pour evenly over layers.
  4. Cover and cook on LOW for 4 hours or HIGH for 2.5 hours.
  5. Preheat broiler to HIGH. Uncover casserole and sprinkle remaining 1 cup cheese on top.
  6. Place under broiler for 2–3 minutes, or until cheese is bubbly and golden.
  7. Garnish with parsley and let rest 5 minutes before serving.

Notes

  • For extra crispiness, broil 1–2 minutes longer, watching closely.
  • For a lighter version, substitute turkey sausage and use half-and-half instead of heavy cream.
  • Serve with a simple green salad for balance.
