Cook the bacon in a large skillet over medium heat until crisp. Remove bacon from skillet with a slotted spoon and set aside on a paper towel lined plate. Discard all but 2 tbsp of the bacon grease and return skillet to stovetop. Brown the ground beef and onion in the remaining bacon grease until no longer pink and onions are tender, about 5 minutes.
Add the ground beef mixture, bacon and remaining ingredients to the slow cooker and stir to combine. Cook on LOW for 3 to 4 hours or HIGH for 1 to 2 hours. Stir before serving and enjoy.
