Cook the ground beef in a pan over medium heat, set it aside and drain the grease from the pan.
Cook the bacon in the pan until crispy, about 6-10 minutes, set aside and drain all but a tablespoon of the grease.
Add the onion and saute until tender, about 5-7 minutes.
Add the garlic and saute until fragrant, about a minute.
Mix the ground beef, bacon, onions and garlic, cream cheese, sour cream, mayonnaise, mozzarella, cheddar, worcestershire sauce and ketchup and pour it into a baking dish.
Bake in a preheated 350F/180C oven until the top starts turning a light golden brown and then sides are bubbling, about 20-30 minutes.
