  • 4 cups potatoes, cleaned and sliced thin
  • 1 cup reserved potato water
  • 1 pound ground pork sausage
  • 1 cup thinly sliced onions (optional)
  • 1 cup cheddar cheese, shredded
  • 3 Tablespoons margarine or butter
  • 1/4 cup flour
  • 1 cup milk


  • Preheat oven to 375 degrees F. Spray a 13 x 9 inch baking dish with non-stick cooking spray.
  • Boil in salted water the cleaned, sliced potatoes for 5 minutes. Reserve 1 cup of cooking water; drain the remaining water.
  • Brown pork sausage loosely; drain excess grease.
  • In a small saucepan; melt margarine. Add flour and stir until smooth.
  • Slowly add 1 cup reserved potato water and milk; whisking over medium heat until smooth.
  • In the casserole dish, layer all potatoes, onions, sausage and cheese. (First layer potatoes, second layer onions, etc.)
  • Pour white sauce over the entire casserole.
  • Bake for 45 minutes and remove from oven. Let sit for 10 minutes before serving.


  • Love spice? Try using hot pork sausage in this Potato Sausage Casserole.
  • If you are using unseasoned pork sausage, you will want to add salt to the cream sauce. 
  • I did not peel my potatoes because I used Yukon gold potatoes which have a thin skin.  Use whatever potatoes you have on hand and peel if desired before boiling.
  • Onions are optional.  Use as many or as little.  They do add great flavor to this old fashioned casserole without cream of mushroom soup.
  • I like my casseroles golden brown on top.  If you prefer less browning, cook this pork sausage casserole at 350 degrees F for 1 hour.
  • Let the oven sausage casserole sit at room temperature for 10 minutes before serving so that it holds together.
  • Try some more old fashioned casserole recipes like Mom's Tuna Casserole, Cheesy Ham and Potato Casserole and Grandma's Chicken and Rice Casserole.
