In a large skillet, brown the ground beef with the diced onion over medium-high heat until fully cooked, about 8 minutes. Drain any excess fat.
Transfer the beef mixture to your slow cooker and add the diced potatoes and minced garlic.
Pour in the chicken broth and stir in the cream of chicken soup, garlic powder, onion powder, paprika, salt, and pepper.
Cover and cook on low for 5 hours or on high for 2.5 hours, until the potatoes are fork-tender.
About 30 minutes before serving, cut the cream cheese into cubes and stir it into the chili along with 1 cup of the shredded cheddar cheese and half of the crumbled bacon. Stir until the cheese is melted and everything is creamy.
Serve hot in bowls topped with sour cream, green onions, remaining shredded cheese, and the rest of the bacon crumbles. So good!
