Smoked Sausage and Potato Casserole

This layered smoked sausage and potato casserole is a great make ahead dish since you have to cook and cool the potatoes before assembling the casserole.

This casserole features smoked sausage and onion layered with potatoes and covered in white sauce and topped with cheese.

This is one of my favorite casseroles and I make several variations of this basic recipe that I hope to bring you. It’s a pretty basic recipe and one that you most likely already have the ingredients for in your house.

It does take a little planning since you cook the potatoes and let them cool completely before peeling and slicing but that step could be done the night before with  the potatoes stored in the fridge.

Serve this with butter garlic green beans, tangy green beans with bacon, or corn, onion, and pepper sautée.

  • 1 pound smoked sausage , cut into rounds
  • 7-8 medium potatoes
  • 1 small onion , diced
  • 3 Tablespoons flour
  • 3 Tablespoons butter
  • 1 cup water
  • 1 1/2 cup milk
  • To taste salt
  • To taste pepper
  • 1 cup shredded cheddar cheese


  1. Scrub potatoes clean, place in a large pot and cover with water. Add salt, bring to a boil and cook until potatoes can just be pierced with a fork. You want them to be just barely cooked since they will bake in the oven once the casserole is finished. Drain potatoes and let them cool to room temperature then refrigerate until needed.
  2. Preheat oven to 400 degrees. Butter or spray a 9x9” pan or 2 quart casserole dish. Sauté the sausage and onions in a skillet over medium heat until onions are softened and sausage has browned. Remove sausage and onion to a plate and reserve.
  3. Turn heat to medium low and in the same skillet melt the butter, then add the flour, whisking well to combine. Cook and stir for 2 or 3 minutes then slowly add the water whisking constantly to prevent lumps. Once the mixture is smooth and bubbling pour in the milk while stirring. Add salt and pepper to taste and cook over low heat for about five minutes or until mixture has thickened. Remove from heat.
  4. Peel and slice the potatoes. Add 1/3 of the potatoes to the buttered dish, then add 1/3 of the sausage and onions, and 1/3 of the gravy. Repeat layers twice.
  5. Bake for 25-30 minutes or until the casserole is bubbly, top with cheese and bake 5-10 minutes longer until cheese is melted. Let rest for 10 minutes before serving
