How to Make It:

(Full printable recipe card is available below)

Saute the sausage. First, you’ll cook the ground sausage in a large skillet over medium heat, breaking it apart and cooking until fully browned.

Drain excess grease and set the sausage aside.

Layer in the slow cooker. Next, you’ll lightly grease the inside of your slow cooker to prevent sticking.

Add 1/3 of the hash brown potatoes to the bottom of the slow cooker. Sprinkle half of the chopped onions over the potatoes, followed by half of the cooked sausage.

Repeat these layers, then top with the final 1/3 of potatoes and half of the shredded cheese.

Prepare the sauce. Then, you’ll mix the cream of mushroom soup, milk, garlic powder, paprika, and pepper in a separate bowl.

Pour this mixture evenly over the layered ingredients in the slow cooker, then sprinkle with the remaining shredded cheese.

Serve and enjoy!
