Ingredients List
· 1 lb (450g) breakfast sausage or Italian sausage (casings removed)
· 1 bag (30 oz) frozen shredded hashbrown potatoes, thawed slightly
· 1 can (10.5 oz) condensed cream of chicken soup (or cream of mushroom)
· 2 cups shredded sharp cheddar cheese, divided
· ½ cup milk or half-and-half
· Optional: ½ cup sour cream (for extra creaminess)
· Optional: ½ teaspoon black pepper
· Optional: ¼ cup chopped green onions for garnish
Step-by-Step Instructions
Step 1: Brown the Sausage
Heat a large skillet over medium-high heat. Add the sausage and cook for 5-7 minutes, breaking it up with a spoon, until browned and cooked through. Drain any excess fat.
Step 2: Prepare the Slow Cooker
Lightly grease a 6-quart or larger slow cooker with non-stick spray.
Step 3: Mix the Ingredients
In a large bowl, combine the thawed hashbrowns, cooked sausage, cream of chicken soup, milk (and sour cream if using), pepper, and 1 ½ cups of the shredded cheese. Stir until well combined.
Step 4: Layer in the Slow Cooker
Pour the mixture into the prepared slow cooker and spread it into an even layer. Sprinkle the remaining ½ cup of cheese over the top.
Step 5: Cook
Cover and cook on LOW for 4 to 6 hours or on HIGH for 2 to 3 hours. The casserole is ready when the edges are bubbly and the cheese is melted.
Step 6: Garnish and Serve
Sprinkle with green onions if desired. Serve warm.
Cooking Tips and Pro Tips for Best Results
· Thaw the hashbrowns slightly: Frozen hashbrowns cook more evenly if they are not completely frozen. Let them sit at room temperature for 15-20 minutes before using.
· Brown the sausage: Do not skip this step. Browning adds flavor and removes excess fat. Drain well.
· Use full-fat ingredients: Low-fat cream soup and cheese may not melt as smoothly and can result in a thinner casserole.
· Do not overcook: The casserole is done when the edges are bubbly and the center is hot. Overcooking can make the hashbrowns mushy.
· Add a crunchy topping: For extra texture, sprinkle crushed cornflakes or breadcrumbs mixed with melted butter over the top during the last 30 minutes of cooking.
· Make it a full meal: Add 1 cup of diced bell peppers or onions to the sausage while browning.
Variations and Substitutions
Cheesy Sausage and Egg Hashbrown Casserole:
Add 4 large eggs (lightly beaten) to the mixture before cooking. The eggs will set and make the casserole更像 a breakfast bake.
Bacon and Sausage Hashbrown Casserole:
Add ½ cup of cooked, crumbled bacon along with the sausage. The bacon adds extra smoky flavor.
Vegetarian Hashbrown Casserole:
Omit the sausage. Add 8 oz of sliced mushrooms (sautéed) and 1 cup of diced bell peppers. Use cream of mushroom soup instead of chicken.
Spicy Sausage Hashbrown Casserole:
Use hot Italian sausage. Add 1 diced jalapeño and ½ teaspoon of crushed red pepper flakes. Use pepper jack cheese instead of cheddar.
Ham and Cheese Hashbrown Casserole:
Substitute the sausage with 1 ½ cups of diced cooked ham. Ham is already cooked, so you can skip the browning step.
Make-Ahead / Overnight Casserole:
Assemble the casserole in the slow cooker insert, cover, and refrigerate overnight. In the morning, place the insert in the slow cooker and cook as directed. You may need to add 30-60 minutes to the cooking time since the ingredients start cold.

Frequently Asked Questions (FAQ)
1. Can I use fresh shredded potatoes instead of frozen?
Yes. Use about 4 cups of freshly shredded russet potatoes. Squeeze out as much moisture as possible using a clean kitchen towel or paper towels. Fresh potatoes may take slightly longer to cook.
2. Can I make this casserole without cream soup?
Yes. Make a simple sauce: melt 2 tablespoons of butter, whisk in 2 tablespoons of flour, then slowly add 1 cup of milk. Cook until thickened. Use this instead of the soup.
3. Why is my casserole watery?
Watery casserole usually comes from using frozen hashbrowns that were not thawed properly (excess ice crystals melt during cooking). Thaw the hashbrowns and pat them dry with paper towels before using. Also, avoid adding extra liquid.
4. Can I cook this on high instead of low?
Yes, but low is preferred. Cooking on low for 4-6 hours allows the flavors to meld and the hashbrowns to become tender without becoming mushy. On high, check at 2 hours.
5. Can I add eggs to this casserole?
Yes. Whisk 4-6 eggs with ¼ cup of milk and stir into the mixture before cooking. The eggs will set and make the casserole more like a breakfast bake.
6. Can I freeze this casserole before cooking?
Yes. Assemble the casserole in a freezer-safe container (or line your slow cooker with foil and freeze the foil-wrapped mixture). Thaw overnight in the refrigerator before cooking. You may need to add 1-2 hours to the cooking time.
