Timing
Preparation and cooking time are crucial when it comes to weeknight meals. This Chicken Alfredo Casserole takes approximately 30 minutes to prepare and 30 minutes to bake, totaling 1 hour. This is about 20% less time than the average casserole recipe, making it a perfect choice for busy evenings.
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your casserole bakes evenly and achieves that golden top.
Step 2: Cook the Pasta
In a large pot, bring salted water to a boil. Add the penne pasta and cook according to package instructions until al dente, usually about 8-10 minutes. Drain and set aside.
Step 3: Prepare the Broccoli
In the same pot, add a tablespoon of olive oil and sauté the broccoli florets over medium heat for about 3-4 minutes until they are tender but still vibrant green. This step enhances the flavor and texture of the broccoli.
Step 4: Combine Ingredients
In a large mixing bowl, combine the cooked chicken, sautéed broccoli, cooked pasta, Alfredo sauce, garlic powder, Italian seasoning, salt, and pepper. Stir until everything is well-coated and evenly mixed.
Step 5: Assemble the Casserole
Transfer the mixture into a greased baking dish (about 9×13 inches). Spread it out evenly, then sprinkle the shredded mozzarella and grated Parmesan cheese on top. This will create a delicious, cheesy crust as it bakes.
Step 6: Bake
Place the casserole in the preheated oven and bake for 30 minutes, or until the cheese is bubbly and golden brown. The aroma will fill your kitchen, making it hard to resist!
Step 7: Serve
Once baked, remove the casserole from the oven and let it sit for about 5 minutes before serving. This allows the layers to set and makes serving easier.
