How to Make Slow Cooker Casserole with Sausage

Step 1: Prepare Slow Cooker

Grease the inside of the slow cooker with cooking spray or butter to prevent sticking.

Step 2: Layer Base Ingredients

• Frozen hash browns
• Sliced kielbasa sausage
• Diced onions
• Shredded cheddar cheese (2 cups)

Step 3: Create Creamy Sauce

• Cream of mushroom soup
• Sour cream
• Creole seasoning
• Salt
• Black pepper

Step 4: Blend Ingredients

Pour the sauce over the hash brown mixture and stir thoroughly to ensure even distribution.

Step 5: Top with Cheese

Sprinkle the remaining cheddar cheese (1/2 cup) evenly across the top of the casserole.

Step 6: Slow Cook

• Low setting for 6 hours, or
• High setting for 4 hours

Cooking is complete when potatoes and onions are tender and fully cooked.

Step 7: Serve and Enjoy

Scoop the hot casserole onto plates and serve immediately. This hearty dish pairs wonderfully with a simple green salad or crusty bread.

Tip: Let the casserole rest for 5-10 minutes after cooking to allow flavors to settle and make serving easier.

Tips to Get Creamy Potatoes and Sausage Right

• Prevent Potato Mushiness: Opt for frozen hash browns instead of fresh potatoes to maintain a better texture during long slow cooking.
• Cheese Melting Magic: Add the final cheese sprinkle during the last 30 minutes of cooking to keep it perfectly melted and prevent burning.
• Flavor Boost Technique: Use smoked kielbasa for deeper, richer flavor that complements the creamy potato base.
• Seasoning Secret: Adjust creole seasoning to taste, starting with less and adding more to control spice level without overwhelming the dish.
• Easy Prep Hack: Chop onions and slice kielbasa the night before to streamline morning cooking and save valuable time.

Reheating Sausage and Potato Casserole Smoothly

• Refrigerate: Store leftovers in an airtight container within two hours of cooking, keeping them fresh for 3-4 days in the refrigerator.
• Freeze: Transfer cooled casserole to freezer-safe containers, sealing tightly to prevent freezer burn, and store for up to 2 months.
• Reheat: Warm individual portions in the microwave for 1-2 minutes, stirring halfway through, or place in a preheated 350°F oven for 15-20 minutes until heated thoroughly and cheese is bubbly.

Great Pairings for This Comforting Casserole

• Craft Hearty Red Wine Pairing: Select a robust Cabernet Sauvignon or Syrah to complement the rich, savory flavors of the kielbasa and creamy potato casserole, cutting through the dish's richness with bold tannins.
• Zesty Salad Side Kick: Prepare a crisp mixed green salad with tangy vinaigrette to balance the casserole's heaviness, adding brightness and freshness to the meal with cucumber, tomatoes, and light herbs.
• Elevate with Crusty Bread: Serve warm, crusty sourdough or French bread alongside the casserole, perfect for soaking up the creamy sauce and adding delightful textural contrast to each comforting bite.
• Cool Beverage Refresh: Offer a cold, light beer like a pilsner or wheat beer to cleanse the palate and provide a refreshing counterpoint to the dish's creamy, hearty profile.
