Creating Slow Cooker Sausage and Potato Casserole is simple when you follow these steps:

1. Prepare Ingredients: Start by washing and cubing the potatoes. Chop the onion into small pieces.
2. Layer the Ingredients: In the slow cooker, place the cubed potatoes, followed by the chopped onion and sliced sausage.
3. Combine Seasonings: In a separate bowl, whisk together heavy cream, chicken broth, garlic powder, paprika, Italian seasoning, salt, and pepper.
4. Pour Mixture Over Ingredients: Pour the cream mixture evenly over the sausage and potatoes in the slow cooker, ensuring they are well coated.
5. Add Cheese: Sprinkle half of the shredded cheese over the top of the casserole ingredients.
6. Cover and Cook: Cover the slow cooker and set it to the low setting for 6-8 hours (or high for 3-4 hours).
7. Check for Doneness: About half an hour before the casserole finishes cooking, check the potatoes for tenderness.
8. Add Remaining Cheese: Once the potatoes are tender, add the remaining cheese on top, cover, and allow it to melt.
9. Serve Hot: When fully cooked, stir gently and serve hot.

These steps will guide you in crafting this amazing casserole with minimal fuss. The slow cooking allows all the flavors to meld beautifully, making each bite a perfect blend of textures and tastes.
