🔪 Instructions (Total Time: ~30 Minutes)
1. Prep and Cook Pasta (10 Minutes)
- Preheat & Prep: Preheat your oven to 190°C (375°F). Grease a 9×13 inch casserole dish.
- Cook Pasta & Broccoli: Bring a large pot of salted water to a boil. Add the pasta and cook it for 1 minute less than the package directs (al dente).
- Add the broccoli florets to the boiling water during the last 2 minutes of the pasta cook time.
- Drain the pasta and broccoli and transfer them directly to the prepared casserole dish.
2. Mix the Casserole (5 Minutes)
- In a separate bowl, whisk together the Alfredo sauce, milk/half-and-half, garlic powder, Italian seasoning, and 1/4 cup of the Parmesan cheese.
- Add the cooked chicken and the sauce mixture to the pasta and broccoli in the casserole dish. Toss everything gently until the pasta and ingredients are fully coated.
- Spread the mixture into an even layer in the dish.
3. Bake and Serve (15 Minutes)
- Top: Sprinkle the top evenly with the remaining 1/4 cup Parmesan cheese and then the Mozzarella cheese.
- Bake: Bake, uncovered, for 15–20 minutes, or until the casserole is bubbly hot throughout and the mozzarella cheese is fully melted and lightly golden brown.
- Let the casserole rest for 5 minutes before serving.
