Preparation Steps

• Cook the macaroni according to package instructions until al dente. Drain and set aside.
• In a large saucepan, melt the butter over medium heat. Add the flour and whisk until smooth.
• Gradually whisk in the milk, mustard powder, salt, and black pepper. Continue whisking until the mixture thickens, about 5 minutes.
• Reduce the heat to low. Stir in the cheddar, Colby-Jack, and American cheeses until fully melted and smooth.
• Add the cooked macaroni to the cheese sauce and stir until fully coated.
• Serve hot, optionally garnished with a sprinkle of paprika.
