Preheat the oven to 375°F (190°C).
In a skillet over medium heat, drizzle olive oil and cook seasoned chicken breasts until golden brown (5-7 minutes per side). Remove from heat and cut into bite-sized pieces.
Boil salted water in a large pot, cook pasta according to package directions until al dente, then drain.
In a large bowl, mix cooked pasta, broccoli florets, cut chicken, and Alfredo sauce until well combined.
Pour the mixture into a greased baking dish and top with Parmesan cheese.
Bake for 25-30 minutes or until bubbly and golden brown.
