I like to change things up a bit sometimes so I make my scalloped potatoes with kielbasa sausage on occasion . It's quite tasty. Just peel, rinse, dry and slice as many potatoes to the size casserole dish or pan you need. Of course if your making a huge pan add extra butter too. Be sure you make them in a deep enough pan to they won't bubble over in your oven.
You will need:
amount you desire of thinly sliced potatoes ( peeled )
1 pkg lean kielbasa or turkey kielbasa, slice as much as you feel you need
1 large onion , sliced
1 stick butter , cubed
1 tbls. flour
salt and pepper
Whole Milk to cover entire casserole.
Butter your dish and alternate layers starting with potatoes, then onion, more potatoes, kielbasa, flour sprinkled over , and cubed butter spread around. End with a last layer of potatoes with more kielbasa on top. Sprinkle with salt and pepper . Pour milk over them to completely cover and bake about 2 hours or more for larger pan until potatoes are very tender in a 350 degree oven. ( Smaller casserole might get done sooner).
Remove from oven and let stand to cool and thicken up a bit about 15 minutes before you serve them.
And here's a hint. If you have never tried throwing a dab of butter in a fry pan and frying leftover scalloped potatoes until browned on both sides you should try it ! It's yummy.
