Instructions
Preheat oven to 350 degrees F. Use a mandolin or slicer to achieve same size potato slices so they cook evenly, about 1/8" in size.
Add potato slices into a cool bowl of water. Add a bit of oil into a skillet over medium high heat. Add diced onions and cook a bit to soften, then add ground sausage and ground beef. Break up, add minced garlic and cook until meat is no longer pink. Drain grease and set aside.
In a bowl whisk together the cream, cream of mushroom soup and seasonings.
Spray 9x13" dish lightly with non stick spray. Drain potatoes and pour on to a few paper towels. Press down to absorb excess water on outsides.
Lay 1/3 of potatoes in dish, pour 1/3 of ground beef mixture on top with 1/2 cup of your shredded cheese on top of that, and finally 1/3 of soup mix on top. Continue with this for 3 layers total with your remaining 1.5 cups of cheese on the very top.
Cover casserole dish with foil and bake for 1 hour 15 minutes. Then uncover and bake for an additional 20-25 minutes or until potatoes are tender and cheese is lightly browned and melted.
Sit and rest when done on a cooling rack for 15 minutes before serving with a dollop of sour cream and chives on the top of each serving.
