Step 3: Fill the Slow Cooker - Transfer the browned beef to a
6 quart slow cooker. Add the diced onion and minced garlic, then pour in the beef broth. Stir in the undrained Rotel, cheddar cheese soup, and taco seasoning until the soup is mostly blended into the liquid. It may not look completely smooth yet, and that is fine. As the cooker warms, the soup loosens and everything settles into a creamy, seasoned broth around the beef.
