Creating Creamy Baked Mac and Cheese can be fuss-free if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Cook Pasta: In a large pot, bring salted water to a boil. Add the elbow macaroni and cook until al dente, about 7-8 minutes. Drain and set aside.
3. Melt Butter: In a medium saucepan, melt the butter over medium heat.
4. Make Roux: Once melted, add the flour and whisk constantly for about 1 minute to form a roux.
5. Add Milk: Gradually whisk in the whole milk until the mixture is smooth. Cook for 3-5 minutes until slightly thickened.
6. Season Sauce: Stir in garlic powder, onion powder, paprika, salt, and black pepper.
7. Add Cheese: Remove the sauce from heat and add the shredded cheddar, mozzarella, and pepper jack (if using), stirring until the cheese melts completely.
8. Combine Pasta: In a large mixing bowl, combine the cooked macaroni with the cheese sauce. Mix until evenly coated.
9. Transfer to Baking Dish: Pour the mac and cheese mixture into a greased 9×13 inch baking dish.
10. Prepare Topping: In a small bowl, mix the breadcrumbs with the grated Parmesan cheese. Sprinkle this mixture evenly over the mac and cheese.
11. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and bubbly.
12. Cool: Once baked, remove from the oven and let it cool for 5-10 minutes before serving.
