Bring a large pot of salted water to a boil. Add the elbow macaroni and cook according to package instructions until al dente, usually about 7-8 minutes. Drain the pasta and set aside.
In a medium saucepan over medium heat, melt the butter. Once melted, whisk in the flour and cook for about 1-2 minutes, stirring constantly to form a smooth paste.
Slowly whisk in the milk and chicken broth, ensuring no lumps form. Continue cooking and stirring until the mixture thickens and coats the back of a spoon, about 5-7 minutes. Stir in the minced chipotle in adobo sauce, smoked paprika, garlic powder, onion powder, salt, and black pepper.
Remove the sauce from heat and stir in the shredded sharp cheddar and Monterey Jack cheeses until melted and silky smooth.
Fold the cooked macaroni and shredded chicken into the cheese sauce, mixing gently to coat evenly.
Preheat your oven to 375°F (190°C). Transfer the mac and cheese mixture into a greased baking dish. Sprinkle the cooked, crumbled turkey bacon evenly over the top, followed by the breadcrumbs.
Bake uncovered for 20-25 minutes, or until the top is golden brown and crispy. For extra crunch, broil for an additional 1-2 minutes, watching carefully to avoid burning.
Remove from the oven and sprinkle with chopped fresh parsley. Serve hot and enjoy!
