How to make Sausage Casserole in Slow Cooker

Creating the Cheesy Soup Mixture: Get a medium-sized mixing bowl. Pour in the cheddar cheese soup and add an equal amount of sour cream. 

Fold in 3/4 cup of the shredded Colby Jack cheese. The cheese should melt slightly and blend well with the soup and sour cream, creating a smooth, creamy mixture.

Season your soup mixture with a pinch of salt and pepper. Adjust these seasonings according to your personal taste preferences.

Preparing the Potato Layer: Place the frozen diced potatoes at the bottom of the slow cooker. These potatoes will form the base layer of your casserole.

Sprinkle the potatoes with a generous amount of paprika and garlic powder, followed by a light seasoning of salt and pepper. Mix the potatoes and seasonings well to ensure they are evenly coated.

Adding Onions and Sausage: Once your potatoes are seasoned, take the diced onions and sprinkle them evenly over the potato layer. Next, arrange the sliced smoked sausage rounds on top of the onions.

Topping with the Soup Mixture: Take the creamy soup and cheese mixture you prepared earlier and spoon it over the sausage layer. Be sure to spread the mixture evenly to cover the sausage and onions.

Cooking the Casserole: Cover the slow cooker with its lid. Set the temperature to low, and allow the casserole to cook undisturbed for 4 to 6 hours. 

Adding the Final Cheese Topping: After the cooking time has elapsed and the potatoes are tender, stir the casserole gently to mix the layers. Sprinkle the remaining 1/4 cup of shredded Colby Jack cheese over the top of the casserole. 

Cover the slow cooker once again and let the casserole stand for about 15 minutes. 

Serving: Once the cheese topping is melted and gooey, your sausage potato casserole is ready to serve. Spoon the hot, creamy, and cheesy casserole directly from the slow cooker into serving dishes.

Can I switch out the cream soups type?

Definitely! If you’re not a fan of cheddar cheese soup, feel free to use cream of chicken soup or cream of mushroom soup instead.

What’s the shelf life of leftovers?

Leftovers can be kept fresh in the fridge for up to 3 days. Just make sure to store them in an airtight container. When you’re ready to eat, warm it up in either the microwave or the oven.

Is this dish a good option for group meals?

Absolutely, this casserole is a hit at potlucks and other gatherings. Its slow cooker preparation makes it a breeze to carry and keep warm until it’s time to eat.

Any tips for an easy cleanup? 

Using a slow cooker liner is a game-changer for cleaning up. It keeps your crockpot clean, so you can enjoy your meal without dreading the cleanup.

What should I serve with this casserole?

Side dishes that go well alongside this one: Pretty much any vegetable side dish works but we prefer the green ones! Green beansbroccoli, or asparagus are all great choices.
