Step 1: Cook the Pasta

1. Bring a large pot of salted water to a boil.
2. Add pasta and cook 1 minute less than package directions (it will finish cooking in the sauce).
3. Drain and set aside.

Step 2: Make the Garlic Parmesan Cheese Sauce

1. In a large saucepan, melt butter over medium heat.
2. Add minced garlic and cook for 30 seconds until fragrant.
3. Stir in flour and cook for 1 minute, stirring constantly (this creates a roux).
4. Slowly whisk in milk and heavy cream, stirring until smooth.
5. Add Dijon mustard, salt, pepper, paprika, and garlic powder.
6. Bring to a gentle simmer, then reduce heat to low.

Step 3: Add the Cheese

1. Gradually stir in white cheddar, Parmesan, and mozzarella, one handful at a time.
2. Stir until the cheese is fully melted and the sauce is smooth.

Step 4: Combine Pasta & Sauce

1. Add the cooked pasta to the cheese sauce and stir until fully coated.
2. If serving stovetop mac and cheese, serve immediately.

Step 5: Make the Crispy Topping & Bake (Optional)

1. Preheat oven to 375°F (190°C).
2. In a small bowl, mix panko breadcrumbs, melted butter, Parmesan, and garlic powder.
3. Pour mac and cheese into a buttered baking dish and sprinkle the topping evenly over the top.
4. Bake uncovered for 15-20 minutes, until the topping is golden brown and crispy.

Step 6: Serve & Enjoy!
