In a large skillet set over medium-high heat, add the ground beef and sprinkle with your favorite taco seasoning blend. Cook the meat thoroughly, breaking it apart with a spatula as it browns, until no pink remains and the beef is fully cooked through.
While the meat sizzles, cube the Velveeta cheese into small, even chunks to help it melt more efficiently.
Once the ground beef is browned, drain off any excess grease from the pan. Reduce the heat to medium, then stir in the cubed Velveeta and the full contents of the Rotel can, including the juices.
Continue to cook, stirring frequently, until the cheese is completely melted and the dip becomes creamy and homogeneous in texture.
To maintain that rich, smooth consistency, keep the dip warm while serving. A slow cooker set to warm or a fondue pot works great for this purpose. Serve hot with tortilla chips, bread cubes, or fresh-cut vegetables.
