5-Ingredient Slow Cooker Hash Brown Casserole

This 5-ingredient slow cooker hash brown casserole is an easy, cheesy side dish that works well for brunches, family dinners, holidays, and potlucks. Frozen hash brown patties create hearty layers while Colby Jack cheese, sour cream, and cream of chicken soup make the casserole rich and creamy.

The slow cooker does most of the work, making this a convenient option when oven space is limited. Serve it alongside ham, roast chicken, turkey, or sausages, or add it to a brunch spread with eggs and fresh fruit.

 

Ingredients

8 frozen patty-style hash browns
2 cups shredded Colby Jack cheese, divided
1 can (10.5 ounces) condensed cream of chicken soup
1 cup sour cream
4 tablespoons melted butter

 

Directions

1. Prepare the slow cooker: Lightly grease the inside of an oval slow cooker.
2. Make the sauce: In a bowl, stir together the cream of chicken soup, sour cream, melted butter, and 1 1/2 cups of the shredded Colby Jack cheese.
3. Layer the casserole: Arrange 4 frozen hash brown patties in a single layer in the bottom of the slow cooker. Spread half of the creamy cheese mixture over them. Add the remaining 4 patties and spread the rest of the mixture over the top.
4. Cook: Cover and cook on LOW for 4–5 hours, or until the hash browns are tender and the casserole is heated through.
5. Add the cheese: During the last 20 minutes, sprinkle the remaining 1/2 cup of cheese over the top. Cover and continue cooking until melted.
6. Optional browning: If your slow cooker insert is oven-safe, place it under the broiler for 2–3 minutes for a browned, crispy top. Watch closely while broiling.
7. Rest and serve: Let the casserole rest for about 10 minutes before serving.

 

Variations & Tips

• For extra flavor, add a little black pepper, onion powder, or garlic powder to the sauce.
• Cream of mushroom or cream of celery soup can be substituted for the cream of chicken soup.
• Slow cookers naturally create a soft, creamy casserole. For crispier edges and a browned top, use the broiler method at the end if your insert is designed for oven use.
• For easier morning preparation, mix the sauce the night before and refrigerate it in a covered container. Assemble the casserole when you’re ready to cook.

 

What to Serve With Hash Brown Casserole

Serve it with baked ham, roast chicken, turkey, or grilled sausages. For brunch, pair it with scrambled eggs, fresh fruit, or a simple green salad.

 

Storage & Reheating

Refrigerate leftovers in a covered container and reheat until hot. The casserole is best served warm, when the cheese is soft and creamy.
