Combine diced potatoes, onion, celery, carrots, chicken broth parsley and basil in your slow cooker. Stir. Cook on low 8 hours (or high 4-6 hours!) until potatoes and veggies are tender.
About 30 minutes before the veggies and potatoes are done, cook the ground beef in a medium skillet about 4-5 minutes until brown. Remove and set aside.
In the same pan, add the butter. Melt the butter and add flour and cook until bubbly. Add the salt, pepper and sour cream.
Add cream mixture, cheese, and ground beef to the crockpot. Stir. Cook until the cheese is melted. Serve with bacon and cheese on top (optional).
