Ingredients

• 16 ounces Elbow macaroni
• 4 tablespoons Unsalted butter
• 4 tablespoons All-purpose flour
• 3 cups Whole milk
• 1 cup Heavy cream
• 4 cups Sharp cheddar cheese, shredded
• 2 cups Mozzarella cheese, shredded
• 1 cup Parmesan cheese, grated
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 teaspoon Garlic powder
• 1 cup Panko breadcrumbs
• 2 tablespoons Olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish and set aside.

Step 2

Cook the elbow macaroni in a large pot of salted boiling water until al dente, according to package instructions. Drain and set aside.

Step 3

In a large saucepan over medium heat, melt the butter. Once melted, whisk in the flour and cook for 1-2 minutes until a paste forms (this is a roux).

Step 4

Gradually pour in the milk and heavy cream, whisking constantly to ensure smoothness. Bring the mixture to a low simmer and cook until it thickens, about 3-4 minutes.

Step 5

Reduce heat to low, then stir in the cheddar, mozzarella, and parmesan cheeses a handful at a time. Stir until the cheeses are fully melted and the sauce is creamy.

Step 6

Add the salt, black pepper, and garlic powder to the cheese sauce. Taste and adjust seasoning if needed.

Step 7

Combine the cooked pasta with the cheese sauce in the saucepan and stir to coat evenly. Transfer the mixture to the prepared baking dish and spread it out evenly.

Step 8

In a small bowl, mix the panko breadcrumbs with olive oil until evenly coated. Sprinkle the breadcrumb mixture over the mac and cheese in an even layer.

Step 9

Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and crispy.

Step 10

Let the mac and cheese cool for 5 minutes before serving. Enjoy!
