In a large skillet over medium-high heat, cook the sausage, breaking it into small pieces as it browns. Once fully cooked and no pink remains, drain off any excess grease. Return the sausage to the skillet or transfer it to the base of a small slow cooker.
Add the cubed cream cheese and undrained diced tomatoes to the browned sausage. If cooking on the stove, cook over medium-low heat, stirring often, until the cream cheese is melted and creamy. If preparing in the slow cooker, combine the sausage, cream cheese, and rotel in the base of the slow cooker and cook on low heat for 30-45 minutes, stirring every 15 minutes, until the cream cheese has melted and the dip is creamy.
Once the cream cheese has melted and the dip is warmed through, serve immediately OR keep the dip warm in the slow cooker (on the warm setting) for up to 4 hours.
Notes
Sausage: You can use pork, chicken, turkey ground sausage. Bulk sausage (like Jimmy Dean regular) is best for this recipe. While Italian sausage can be used, do not use breakfast sausage. Cream Cheese: You can use full fat or reduced fat, but do not use fat-free cream cheese, as it will separate when cooked. Diced Tomatoes with Green Chiles: Use mild, regular, or spicy Rotel based on your spice preference.Storage: Store leftover dip in a sealed container in the fridge for up to 3 days and reheat in a saucepan over low heat or in a heat-safe dish in the microwave in 30-second intervals until the dip has warmed through. Nutrition has been calculated based on turkey sausage and full-fat cream cheese.
