Heat a large sauté pan over medium heat.
Once hot, add in beef, onion, carrots, celery, and garlic, and cook, breaking up the meat as you go, until the beef is no longer pink, about 10 minutes.
Drain any excess grease, then stir in the flour.
Pour the mixture into a greased 6 quart crockpot, then stir in potatoes, broth, half and half, ketchup, mustard, pickle juice, worcestershire sauce, salt, pepper, cheddar cheese, sour cream, cream cheese, and mayo.
Cover and cook on HIGH for 5 hours or LOW for 10 hours or until the potatoes are fork tender.
Taste and re-season, if necessary, then serve and enjoy!
