Step 1: Cook the Pasta. Start by bringing a large pot of salted water to a boil. Add the penne pasta and cook according to package instructions until al dente. Once cooked, drain the pasta in a colander and set aside.
Step 2: Prepare the Broccoli. In the same pot, add the broccoli florets to the boiling pasta water for the last 2-3 minutes of cooking. This will blanch the broccoli, keeping it bright and tender. Drain along with the pasta and set aside.
Step 3: Mix the Ingredients. In a large mixing bowl, combine the shredded chicken, cooked pasta, blanched broccoli, ricotta cheese, chicken broth, garlic powder, onion powder, Italian seasoning, salt, and pepper. Mix well until everything is evenly coated.
Step 4: Assemble the Bake. Preheat your oven to 350°F (175°C). Grease a baking dish with olive oil. Pour the pasta mixture into the dish and spread it out evenly. Top the mixture with shredded mozzarella cheese and grated Parmesan.
Step 5: Bake. Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown.
Step 6: Serve and Enjoy! Once the Chicken and Broccoli Pasta Bake is done, remove it from the oven and let it cool for a few minutes. Serve hot and enjoy the comforting flavors!
