All of the goodness of cheesy nachos packed right into this soup! Slow cooked to perfection and topped with tortilla chips, this soup will become an instant favorite!
In a medium-sized skillet cook the 1 pound lean ground beef, 1 chopped small onion, and 1 clove minced garlic until the beef is no longer pink and the onion is clear. Drain the grease and add the meat mixture to the slow cooker.
Add the 1 (1-ounce) package taco seasoning, 1 (10-ounce) can condensed nacho cheese soup, 1 (10-ounce) can diced tomatoes and green chilis, and 1 ½ cups milk. Stir to combine and put the lid on the slow cooker.
Cook on LOW for 3-4 hours. Stir in 1 cup sharp cheddar cheese and continue cooking until it's melted.
The soup can be kept on warm for an additional 4 hours. Top with crushed Crushed tortilla chips and additional cheese if desired.
