About the Ingredients
Cooked Chicken
Cooked chicken adds hearty protein and makes this recipe quick to assemble. Shredded or diced chicken both work well.
Broccoli Florets
Broccoli adds freshness, texture, and color. Lightly steaming keeps it tender while preventing sogginess in the bake.
Pasta
Short pasta shapes like penne, rotini, or shells hold the sauce well and bake evenly without becoming mushy.
Alfredo Sauce
Alfredo sauce provides the creamy base of the casserole. Store-bought works perfectly, or you can use homemade for extra richness.
Mozzarella and Parmesan Cheese
Mozzarella melts smoothly for a gooey topping, while Parmesan adds salty, savory depth and a golden finish.
Tips & Tricks
Cook Pasta Al Dente
Cook pasta just to al dente so it doesn’t overcook in the oven, ensuring a perfect texture in each bite.
Steam Broccoli Briefly
Steam broccoli briefly to keep it bright and firm, enhancing its flavor and texture in the bake.
Mix Sauce Thoroughly
Mix the sauce thoroughly to coat every bite, ensuring even distribution of flavors throughout the dish.
Pro Tips
- Add garlic directly to the sauce for extra flavor
- Use freshly grated Parmesan for best melting
- Cover loosely with foil if the cheese browns too quickly
Step-by-Step Instructions
Preheat the Oven
Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish to prevent sticking.
Cook Pasta and Broccoli
Cook the pasta according to package instructions until al dente. During the final few minutes of cooking, add the broccoli florets to the pot to blanch them lightly. Drain both and set aside.
Combine Ingredients
In a large mixing bowl, combine the cooked chicken, broccoli, Alfredo sauce, minced garlic, Italian seasoning, salt, and pepper. Stir until everything is evenly coated.
Assemble the Bake
Add the drained pasta to the mixture and gently toss until fully combined. Transfer the mixture to the prepared baking dish, spreading it evenly.
Bake the Casserole
Sprinkle mozzarella and Parmesan cheese over the top. Bake uncovered for 25–30 minutes, until the cheese is melted, bubbly, and lightly golden.
Rest and Serve
Remove from the oven and let rest for about 5 minutes before serving. This allows the bake to set and makes it easier to slice.
Delicious Variations
Add Bacon
Incorporate cooked bacon for a smoky flavor that pairs wonderfully with the creamy Alfredo sauce.
Use Rotisserie Chicken
For convenience, substitute with rotisserie chicken, which adds a delightful depth of flavor.
Substitute Cauliflower
Swap out the broccoli for cauliflower to change up the flavor profile while maintaining texture.
