    Reasons to love it

    • Excellent for a weeknight meal, Sunday dinner, pot lucks or entertaining.
    • Smooth and lusciously creamy white sauce.
    • Perfectly cooked pasta and broccoli - No mushy pasta bakes here! 
    • A complete meal in one dish! rotein, veggies, and pasta all baked to perfection!
    • Versatile! Feel free to use any short pasta you have on hand, swap out the broccoli for your favorite veggies, or even replace the chicken with rotisserie chicken for added convenience!

    Ingredients you’ll need:

    • Penne: Another short pasta, such as bow tie, rigatoni or fussili would work nicely too.
    • Fresh broccoli florets: Keep the broccoli in larger pieces to prevent it from turning mushy after baking in the oven, as it cooks quickly and becomes tender in no time.
    • Chicken thighs or breasts: I personally love thighs because they cook up juicy and tender without being over cooked during the baking time.
    • Parmesan and mozzarella cheese: The parmesan is used to make the white sauce and also sprinkled on top, along with the mozzarella. Be sure to check out more parmesan recipes.
    • Garlic: Enhances the overall flavor of the sauce.
    • Milk and heavy cream: I use a 4:1 ratio of whole milk to heavy cream – 4 cups of milk and 1 cup of cream. It adds just the right amount of richness without being too heavy. If you're keeping it simple or making it for a weeknight dinner, you can use 5 cups of whole milk instead.
    • Flour: It helps thicken the milk and cream, preventing the white sauce from being runny and giving it a smooth, velvety texture.

    Best casserole dish ideal for baked pasta

    For this chicken broccoli alfredo pasta bake, I recommend using a 9x13-inch casserole dish. If you're feeding a smaller family, you can easily halve the recipe and bake it in an 8x8-inch square dish.

    Some casserole dishes come with a matching lid, which is perfect for storing leftovers or transporting the dish to a potluck or gathering. For entertaining, ceramic dishes are a great choice—they add vibrant color and make for a beautiful presentation at the table.

    Make ahead instructions

    1. Cook the pasta and broccoli.
    2. Cook the chicken, sauce and then assemble in the baking dish.
    3. Skip topping with the cheese and let cool completely.
    4. Cover and refrigerate for up to 2 days.
    5. Top with both cheese and bake as instructed. Add an additional 5 to 10 minutes of baking time.

    Recipe tips

    • Undercook the pasta by 2 minutes to prevent it from becoming mushy as it bakes.
    • Cut broccoli into large florets.
    • Use chicken thighs or breasts.
    • Skip heavy cream and use 5 cups of whole milk.

    Recipe FAQs

    Should you boil pasta before pasta bake?

    Yes, it's best to boil the pasta before baking it. Cooking it until it's al dente, or slightly firm, ensures it won’t become overcooked or mushy in the oven. The pasta will continue to cook and absorb the sauce as it bakes, so pre-boiling helps prevent it from soaking up too much sauce and losing its texture.

    What type of pasta is best for bake?

    The best pasta for baking are short pasta shapes like penne, ziti, rigatoni, fusilli, or rotini because they’re the perfect size to complement the chicken and broccoli, making each bite both flavorful and easy to eat. Also, they have grooves that can hold sauce well and withstand the baking process.

    Should I cover my pasta bake in the oven?

    Yes, it's a good idea to cover your pasta bake in the oven, especially during the first part of baking. This helps trap moisture, preventing the pasta from drying out and ensuring the sauce stays creamy. You can uncover it during the last 10-15 minutes to achieve a golden, crispy top.
