Ingredients
Main Ingredients
| Ingredient | Quantity | Notes |
| Raw ground breakfast sausage | 1½ lb (680 g) | Mild or hot |
| Frozen diced hash brown potatoes | 1 bag (32 oz / 907 g) | With onions and peppers |
| Condensed cream of mushroom soup | 1 can (10.5 oz / 300 g) | Undiluted |
| Low-sodium chicken broth | 1 cup (240 ml) | Adjust if needed |
| Shredded cheddar cheese | 1 cup (about 115 g) | Sharp or mild |
| Dried Italian seasoning | 1 teaspoon | Or mixed dried herbs |
Step-by-Step Instructions
Step 1: Prepare the Slow Cooker
Lightly grease the inside of your slow cooker with nonstick cooking spray or a little oil. This helps prevent sticking and makes cleanup easier.
Step 2: Add the Ground Sausage
Place the raw ground breakfast sausage in the bottom of the slow cooker.
Break it into small, evenly sized pieces using a spoon or clean hands. Spread the sausage across the bottom so it cooks as evenly as possible.
Step 3: Add the Frozen Hash Browns
Spread the frozen diced hash brown potatoes evenly over the sausage.
Keep the potatoes frozen when adding them. The onions and peppers already included in the hash brown mixture add extra flavor and convenience.
Step 4: Prepare the Creamy Sauce
In a medium bowl, whisk together the condensed cream of mushroom soup, low-sodium chicken broth, and dried Italian seasoning until smooth.
Make sure the soup is fully blended with the broth so the sauce pours easily over the casserole.
Step 5: Pour the Sauce Over the Ingredients
Pour the creamy soup mixture evenly over the frozen potatoes and sausage.
Use a spoon to spread the sauce gently if needed, making sure it reaches different areas of the casserole.
Step 6: Slow Cook
Cover the slow cooker with the lid and cook on LOW for approximately 6–7 hours or HIGH for 3–4 hours.
The casserole is ready when the potatoes are tender and the sausage is fully cooked. Because raw ground sausage is used, check that it reaches a safe internal temperature of 160°F (71°C) for pork sausage or 165°F (74°C) for poultry sausage.
Step 7: Add the Cheddar Cheese
During the final 15 minutes of cooking, sprinkle the shredded cheddar cheese evenly over the top.
Replace the lid and continue cooking until the cheese melts completely.
Step 8: Serve and Enjoy
Turn off the slow cooker and let the casserole rest for a few minutes before serving.
Spoon generous portions onto plates and enjoy while warm. The creamy potatoes, savory sausage, and melted cheddar make a delicious combination!
Best Tips for Perfect Slow Cooker Sausage and Hash Brown Casserole
For the best results, use frozen diced hash brown potatoes with onions and peppers. They save preparation time and add extra flavor without requiring additional chopping.
Break the raw sausage into small, evenly sized pieces rather than leaving it in large chunks. This helps it cook more evenly throughout the casserole.
For a less greasy casserole, you can brown the sausage in a skillet before adding it to the slow cooker. Drain the excess fat and then layer the cooked sausage with the frozen potatoes. This optional step also adds a deeper savory flavor.
Avoid adding extra broth unless necessary. Frozen potatoes and sausage release moisture during cooking, and too much liquid can make the casserole watery.
Add the cheddar cheese near the end of cooking rather than at the beginning. This helps it melt smoothly without becoming oily or overcooked.
Best Ingredient Options
Breakfast sausage: Mild breakfast sausage creates a classic savory flavor, while hot sausage adds a little heat. You can also use ground turkey or chicken sausage, adjusting the cooking temperature according to the meat used.
Hash browns: Frozen diced hash browns with onions and peppers are ideal. Plain frozen diced potatoes can also be used, with extra chopped onion and bell pepper added if desired.
Condensed soup: Cream of mushroom soup gives the casserole a rich, earthy flavor. Cream of chicken soup is another excellent alternative.
Cheese: Sharp cheddar adds a bold flavor, while mild cheddar creates a softer, creamier taste. Monterey Jack or a cheddar-Monterey Jack blend also works well.
Seasoning: Italian seasoning adds a balanced herb flavor. You can also use garlic powder, onion powder, paprika, or dried parsley.
Recipe Variations
For a spicy sausage casserole, use hot breakfast sausage and add a pinch of crushed red pepper flakes. This creates a more flavorful dish for anyone who enjoys a little heat.
If you love extra cheese, stir ½ cup of shredded cheddar into the potato and sausage mixture before cooking, then add another cup over the top during the final 15 minutes.
For a richer version, stir ¼ cup of sour cream into the cooked casserole just before serving. It adds a creamy texture and a slight tangy flavor.
You can also add chopped mushrooms, extra bell peppers, or spinach for additional vegetables. Add delicate vegetables such as spinach near the end of cooking to prevent them from becoming too soft.
For a breakfast-inspired variation, serve the casserole with fried or scrambled eggs. It makes a hearty brunch or weekend breakfast.
What to Serve With Slow Cooker Sausage and Hash Brown Casserole
This casserole is filling enough to serve on its own, but it pairs beautifully with a fresh green salad, steamed broccoli, roasted green beans, or sautéed vegetables.
For a breakfast or brunch spread, serve it with scrambled eggs, fresh fruit, biscuits, or warm toast. These lighter sides balance the rich, cheesy potatoes.
If you’re serving it as dinner, garlic bread or warm dinner rolls are wonderful additions. A simple cucumber and tomato salad can also add freshness to the meal.
Make-Ahead Instructions
You can prepare several ingredients ahead of time to make cooking day even easier.
Measure the Italian seasoning, shred the cheddar cheese, and prepare any additional vegetables up to one day in advance. Store everything in separate airtight containers in the refrigerator.
For food safety and the best cooking results, keep the raw sausage refrigerated separately and assemble the casserole just before cooking. Keep the hash browns frozen until you’re ready to add them.
Storage
Allow leftover casserole to cool slightly, then transfer it to airtight containers.
Refrigerate within 2 hours of cooking and store for up to 3–4 days.
Keep the casserole covered to prevent it from drying out. If it becomes thick after refrigeration, add a small splash of chicken broth or milk when reheating.
Reheating
Microwave: Place an individual portion in a microwave-safe dish. Cover loosely and heat in short intervals, stirring gently between intervals until thoroughly heated.
Oven: Transfer the leftovers to an oven-safe baking dish, cover with foil, and warm at 325°F (165°C) until heated through. Remove the foil during the final few minutes if you want the cheese topping to become slightly golden.
Stovetop: Heat smaller portions in a covered skillet over low heat. Add a splash of broth if needed and stir carefully to prevent sticking.
Reheat leftovers to 165°F (74°C) before serving.
Freezing
This sausage and hash brown casserole can be frozen, although the potatoes may become slightly softer after thawing.
Allow the cooked casserole to cool completely, then divide it into individual portions and transfer them to freezer-safe airtight containers.
Freeze for up to 2 months for the best quality. Thaw overnight in the refrigerator before reheating thoroughly.
For an especially fresh cheesy finish, add a little extra shredded cheddar during reheating.
Common Mistakes to Avoid
Thawing the hash browns first: Frozen diced potatoes can go directly into the slow cooker. Thawing them may release extra moisture and affect the casserole’s texture.
Leaving the sausage in large pieces: Large chunks may cook unevenly. Break the raw sausage into smaller pieces before adding the potatoes.
Adding too much broth: The potatoes and sausage release moisture as they cook. Too much liquid can make the casserole watery.
Adding cheese too early: Cheese can become oily or lose its smooth texture during extended slow cooking. Add it during the final 15 minutes.
Not checking the sausage temperature: Cooking times vary between slow cookers. Use a food thermometer to confirm that pork sausage reaches 160°F (71°C) or poultry sausage reaches 165°F (74°C).
Opening the slow cooker repeatedly: Removing the lid allows heat to escape and can extend the cooking time. Keep it covered as much as possible.
Forgetting to drain excess grease: If you choose to brown the sausage before slow cooking, drain excess fat to avoid a greasy casserole.
