Creating Shredded BBQ Chicken Mac and Cheese is a straightforward process when you follow these simple steps:

1. Cook the Pasta: Begin by boiling a large pot of salted water. Cook the elbow macaroni according to the package instructions until al dente. Drain and set aside.
2. Make the Cheese Sauce: In a medium saucepan, melt the butter over medium heat. Add the flour and whisk until smooth, cooking for about 1 minute.
3. Add Liquids: Gradually pour in the milk and chicken broth, continuing to whisk to avoid lumps. Bring the mixture to a simmer until it thickens, around 5 minutes.
4. Season the Sauce: Stir in the garlic powder, onion powder, smoked paprika, salt, and pepper. Mix well.
5. Incorporate Cheese: Lower the heat, then add 1 ½ cups of the shredded cheddar cheese, stirring until melted and creamy.
6. Combine with Pasta: In a large mixing bowl, combine the drained macaroni, shredded BBQ chicken, and cheese sauce. Mix until everything is evenly coated.
7. Prepare for Baking (Optional): If you prefer a baked version, preheat your oven to 350°F (175°C). Transfer the mac and cheese mixture to a greased baking dish.
8. Add Toppings: Top the mixture with the remaining cheddar cheese and crumbled bacon if using.
9. Bake: Place the dish in the preheated oven and bake for 15-20 minutes, or until the cheese is bubbly and golden.
10. Serve: If not baking, serve directly from the mixing bowl or dish. Sprinkle with fresh parsley for added color and flavor.

This step-by-step process ensures that even novice cooks can create a delicious dish that’s sure to satisfy.
