Recipe Tips

  • You can use either shredded or patty hash browns in this recipe. There is very little difference between the two by the time you’re finished cooking.
  • Chopped chives go incredibly well with this dish. You can mix the chives in with the cream and cheese mixture or just sprinkle them over the top once you’re ready to serve.
  • If you want to go one bit further, you can add some bacon, sausage, or even shredded chicken to the dish. Add these to your cheese mix for the best flavorsome outcome.
  • I made use of regular full fat sour cream in this recipe but haven’t tried using low fat. You may find that the result will be slightly different if you use low-fat sour cream.
  • Personally, I wouldn’t cook this for any longer than the recommended four hours; otherwise, you may find it will start to burn, or the cheese will curdle and become a bit unappetizing.

Note: I use a 5.5L (6 Quart) slow cooker for all the recipes that I have on this website unless specified. If you have a smaller or larger slow cooker, then you might need to adjust the ingredients.

    Is it just as good using cheddar cheese ?

      I reckon it would be just as good, if not better. Cheddar tends to have a bit more flavor than mozzarella.

    Could you substitute cream cheese for the sour cream?

      Yes, that should work fine.
