Prep Time: 10 minutes
Cook Time: 4–5 hours (Low) or 2–3 hours (High)
Servings: 6–8 servings

🛒 Ingredients

1 bag (30–32 oz) frozen diced hash brown potatoes
2 cups cooked ham, finely diced
1 can (10.5 oz) condensed cream of chicken soup
1 cup sour cream
2 cups sharp cheddar cheese, shredded (divided)
4 tablespoons (1/2 stick) unsalted butter, melted
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
Salt and freshly ground black pepper to taste

👩‍🍳 Step-by-Step Instructions

Step 1: Prep the Slow Cooker

Lightly grease the inside of a 6-quart (or larger) slow cooker with non-stick cooking spray to prevent the cheese from sticking to the edges.

Step 2: Combine the Ingredients

Directly inside the slow cooker, add the frozen diced potatoes, diced ham, cream of chicken soup, sour cream, melted butter, garlic powder, onion powder, salt, and black pepper. Add exactly 1 cup of the shredded cheddar cheese.

Step 3: Mix and Level

Stir all the ingredients together thoroughly until the potatoes and ham are fully coated in the creamy sauce mixture. Use a spoon or spatula to smooth the top into an even layer.

Step 4: Top with Cheese

Evenly sprinkle the remaining 1 cup of shredded cheddar cheese over the top of the mixture.

Step 5: Slow Cook

Cover the slow cooker with the lid. Cook on LOW for 4 to 5 hours (or on HIGH for 2 to 3 hours). You will know it is done when the potatoes are fork-tender and the cheese on top is completely melted, bubbly, and slightly golden around the edges.

Step 6: Rest and Serve

Turn the slow cooker to the “Warm” setting. Let the casserole sit uncovered for about 5 to 10 minutes before serving. This allows the creamy sauce to thicken up beautifully. Garnish with chopped chives or green onions if desired, and enjoy!

💡 Recipe Tips & Variations

Cheese Options: While sharp cheddar gives the best flavor, you can swap it for a mix of Monterey Jack, Colby, or Pepper Jack if you want a subtle spicy kick.
Lighten it Up: You can use light sour cream and a “healthy request” reduced-sodium cream of chicken soup to cut down on calories without sacrificing the texture.
Add Veggies: Want to sneak in some greens? Stir in 1 cup of frozen peas or small broccoli florets right before cooking.
