In a large skillet, add ground beef, onion, and garlic. Cook until meat is browned. Drain any excess grease.
Add ground beef mixture to a 3-quart slow cooker. Top with cubed Velveeta, sour cream, Rotel, and taco seasoning.
Set the slow cooker to 2 hours on low. Stir the slow cooker occasionally.
Once done, serve warm with chips. Keep dip on warm to keep it creamy.
