Start by bringing a large pot of salted water to a boil. Add your choice of pasta—penne or rotini are ideal because their shapes hold the sauce beautifully. Cook according to package instructions until al dente, usually around 8 to 10 minutes. Drain and set aside.
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add diced bell peppers, red onions, and corn kernels. Sprinkle with garlic powder, onion powder, salt, and pepper. Sauté for 5–7 minutes until the veggies are tender but still have a slight crunch.
In a large mixing bowl, combine the cooked pasta, shredded chicken, sautéed veggies, and BBQ sauce. Stir well until everything is evenly coated in that smoky, tangy sauce.
Transfer the pasta mixture into your greased baking dish. Sprinkle the shredded mozzarella cheese evenly on top, making sure to cover the surface so the cheese melts beautifully into a golden bubbly crust.
Preheat your oven to 375°F (190°C). Place the baking dish in the oven and bake for 20–25 minutes, or until the cheese is melted and bubbling, and the edges are slightly crispy.
Once out of the oven, sprinkle freshly chopped parsley over the top for a pop of color and freshness. Serve hot and enjoy the perfect blend of BBQ flavor and cheesy pasta goodness.
