Melt the Base: Place a medium skillet or saucepan over medium-low heat. Add the softened cream cheese and sour cream, stirring frequently until melted and completely smooth.
Add the Zest & Protein: Stir in the slightly drained can of Rotel tomatoes and green chiles. If you are adding cooked ground beef or sausage, fold it into the mixture now.
Incorporate the Cheese: Reduce the burner heat to low. Add the garlic powder, chili powder, smoked paprika, and shredded sharp cheddar cheese to the pan.
Melt and Smooth: Stir continuously for 3 to 5 minutes until the cheddar cheese is entirely melted and fully incorporated into a thick, uniform consistency.
Garnish and Serve: Remove the skillet from the heat and transfer the mixture into a serving bowl. Garnish the top with sliced green onions and serve immediately alongside tortilla chips, crackers, or fresh veggies.
