While you can make the recipe in a crock pot, you still need to brown the beef on the stove, before adding everything to the slow cooker. Plus, you'll have to add the sour cream at the end, and then let it warm up. So, since you'll already be at the stove, I just recommend finishing it off there as written on the recipe card. The great thing about lazy cabbage rolls is that the cooking process really is perfect for when you're feeling lazy.
