1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
2. Cook the macaroni in a large pot of boiling salted water until al dente, about 7-8 minutes. Drain and set aside.
3. In a large saucepan over medium heat, melt the butter. Stir in the flour to create a roux, cooking for about 2 minutes until it turns a light golden color.
4. Gradually whisk in the milk and cream. Bring to a simmer and cook until thickened, about 5 minutes, stirring frequently.
5. Remove the saucepan from the heat and stir in the cheddar, mozzarella, and Gruyère cheeses until smooth. Season with salt, pepper, paprika, and cayenne.
6. Combine the cooked macaroni with the cheese sauce, stirring until the pasta is evenly coated. Pour the mixture into the prepared baking dish.
7. In a small bowl, mix the panko breadcrumbs with the melted butter. Sprinkle evenly over the macaroni and cheese.
8. Bake in the preheated oven for 25-30 minutes, or until the top is golden and crispy. Let it cool slightly before serving.

As you bake, remember that cooking is a dance. It’s about finding your rhythm and enjoying each step, just like when my family would gather around the kitchen, creating our own little symphony of sounds.
