In a medium pot, bring the broth to a boil. Add the grits, stirring to prevent lumps. Reduce heat to medium-low and stir in the cheeses, half-and-half, and butter. Continue stirring for 10-15 minutes to ensure a creamy texture.
Remove from heat and let stand for 5 minutes before serving. Serve with your toppings of choice.
Notes
Regular stirring will improve the texture of your grits and help even out the cheesy flavor.
