Step 1: Cook the macaroni
Bring a large pot of salted water to a boil. Add the elbow macaroni and cook according to the package instructions until al dente.
Drain the pasta thoroughly and set it aside. Avoid overcooking, as the macaroni will continue absorbing moisture when combined with the warm cheese sauce.
Step 2: Warm the shredded chicken
Heat the olive oil in a large skillet over medium heat.
Add the cooked, shredded chicken breast and stir gently for 2–3 minutes, or until heated through.
Spread the chicken evenly across the skillet so it warms without drying out.
Step 3: Add the BBQ sauce and seasonings
Pour the BBQ sauce over the shredded chicken.
Add the garlic powder, onion powder, smoked paprika, salt, and black pepper.
Stir until every piece of chicken is evenly coated in the smoky barbecue mixture.
Reduce the heat to low and keep the chicken warm while preparing the cheese sauce.
Step 4: Prepare the creamy cheese sauce
Pour the milk into a medium saucepan over medium-low heat.
Warm the milk gently without allowing it to boil.
Gradually add the shredded cheddar and mozzarella, stirring continuously until the cheese melts and forms a creamy sauce.
For the smoothest texture, add the cheese in small handfuls and allow each addition to melt before adding more.
If the sauce becomes too thick, stir in a small splash of additional milk.
Step 5: Combine the pasta and cheese sauce
Add the drained macaroni to the saucepan containing the cheese sauce.
Stir gently until every piece of pasta is coated in the creamy cheddar and mozzarella mixture.
Keep the heat low to prevent the cheese sauce from separating.
Step 6: Fold in the BBQ chicken
Add the prepared barbecue chicken to the cheesy macaroni.
Fold everything together until the chicken is evenly distributed throughout the pasta.
The combination of creamy cheese sauce and smoky barbecue chicken gives BBQ Chicken Mac and Cheese its signature sweet, savory, and comforting flavor.
Step 7: Adjust the seasoning and serve
Taste the finished pasta and adjust the salt, pepper, or smoked paprika if necessary.
For a stronger barbecue flavor, drizzle a little extra BBQ sauce over the top.
Serve immediately while the cheese sauce is warm and creamy.
