Here's a really easy recipe for Cheesy Crockpot Hashbrowns I made today that turned out really good.
1 frozen ham steak
1/2 large bag of frozen shredded hashbrowns
1 can of condensed cheddar cheese soup
6-8 oz of sour cream
6 tbsp finely chopped onion
I cut my ham into cubes right out of the freezer, it made it really quick and easy to cut into small cubes. I threw that into the crockpot along with the onion, soup, and sour cream and then sturred all of it up good. Then I threw the hashbrowns in and stirred it good. I cooked it on high for about 3.5-4 hours (you'll know it's done if the hashbrowns are nice and soft). I stirred it a couple of times after the potatoes got thawed out.
