Brown the ground beef in a skillet over medium heat until fully cooked. Drain the excess grease.
Transfer the cooked beef to the crockpot.
Add the onion, garlic, potatoes, carrots, celery, chicken broth, Worcestershire sauce, parsley, paprika, salt, and black pepper.
Cover and cook on Low for 6 to 7 hours or High for 3 to 4 hours, until the vegetables are tender.
About 30 minutes before serving, stir in the softened cream cheese until melted.
Add the shredded cheddar cheese and heavy cream, stirring until smooth and creamy.
Mix in half of the cooked bacon.
Cover and cook for another 20 to 30 minutes.
Serve topped with the remaining bacon, chopped green onions, and extra cheddar cheese if desired.
