Before serving, add additional salt and pepper to taste if needed.
If you prefer, the soup may be cooked in a large pot on the stove over low heat for 2 to 3 hours.If you are using leftover roast beef that is already cooked, you can omit the butter and skip sautéing the beef. Just chop the roast beef and add it directly to the crockpot.For easier prep, try using frozen hash browns instead of cubing the potatoes. With this shortcut, add the hash browns later in the cooking process so they stay firm. An hour or two before serving would be best, depending on how hot your crockpot cooks.
