Prepare the Ingredients: Cut the Velveeta and cream cheese into small cubes for quicker melting. Drain the liquid from the Rotel tomatoes and cook any meat (ground beef or sausage) if using.
Layer Ingredients in the Crock Pot: Place the Velveeta, cream cheese, Rotel tomatoes, and cooked meat (if using) into the Crock Pot. Sprinkle in the garlic powder, onion powder, chili powder, and cumin. Stir well to combine.
Cook on Low: Cover the Crock Pot and cook on low for 2-3 hours, stirring occasionally to ensure everything melts evenly and blends together smoothly.
Serve and Enjoy: Once the dip is creamy and smooth, it’s ready to serve! Pair it with tortilla chips, crackers, or fresh veggies for dipping. Keep the dip warm in the Crock Pot while serving.
