If you want to personalize this cheesy kielbasa hashbrown casserole or don’t have certain ingredients on hand, we have some variations here that will help.
Fresh Potatoes – If you don’t have frozen hashbrowns, you can simply cube up fresh potatoes.
Onions – Any onion will do. If you happen to have a sweet onion on hand, use that. Even red onions work.
Cream – If you don’t have milk, cream is an excellent alternative.
Make it Spicy – Try adding some red pepper flakes to give this recipe a kick of heat.
Cheese – Aside from cheddar cheese, Colby, Monterey Jack, and Colby Jack work very well in this recipe.
Creamed Soup – This recipe calls for cream of chicken soup, but you an also use cream of mushroom or celery.
This casserole will keep well in the refrigerator for three to four days. For longe storage, you can freeze it for up to a month.

A Sharp Knife – When dicing your onion, a sharp knife is your friend. Even cuts will help you get a nice dice, and a sharp knife makes for even cuts.
Shred Your Own Cheese – Of course, it’s faster to buy shredded cheese, but for the best flavor possible, shred your own cheese using a cheese grater and a block of cheese.
