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.


With a recipe this simple, it shouldn’t come as a surprise that there aren’t many tips for this one. We do have a couple that we think will help you, though.

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.

  1. Could I use diced ham instead of sausage

    1. Hi Janice I don’t see why not. Both are cooked meats. I would just cut the ham so it is about the same size as the kielbasa. Maybe check the cook time. Kielbasa has some fat in it ham is leaner so you don’t want it to overcook and be dry.

    1. We never have but I would think 6-7 hours. Just keep an eye on it

  2. Amy Brooks says:

    I thought this would be thicker. It was good but more like a thicker soup than a casserole.

    1. I would love to see a picture. As you can see from ours it is thick and nothing like a soup

        I wish I had taken a picture. I’m wondering if I did something wrong but I can’t see what. I will try it again though because it was good.

  3. Nicole Reily says:

    Wonder how to do this not in slow cooker, mine won’t heat up.

    1. You can try it on the stove top. Put everything in a pan or pot except for cheese and saute and cook. But I don’t know for how long as I have never done it that way. You may have to add a bit more liquid

    Can I use unsalted butter?
