This Chicken and Broccoli Bake is an amazing dish that’s perfect for using up any of that leftover chicken you have sitting around. Even if you don’t have the leftovers, I’m begging you to cook up some chicken for this recipe- you won’t regret it!
That chicken is going to play perfectly with some broccoli, a bit of pasta, and some creamy alfredo sauce. Together, they’ll become a delicious casserole filling that’s great enough on its own. Instead of stopping there, we added a simple crushed cracker topping that’s just amazing with this dish!
This Chicken Broccoli Alfredo Bake is definitely going to be one of your favorites for busy weeknight dinners. Sure, it takes a few more steps than something like a “dump-and-bake” but that little bit of extra work is definitely worth it. We loved this dish and we’re certain you’ll enjoy it too!

Another dish that’s perfect for a busy weeknight is our Cheesy Chicken and Rice Casserole. This dish is just as delicious and comforting as the Chicken Bake we showed you today- it just uses rice and a few different veggies instead. Plenty of cheddar cheese and cream of chicken soup makes this dish into some tasty comfort food!
-
Of course, we can’t talk about comfort food without bringing up some classic Chicken and Biscuits. Our easy recipe for this timeless comfort dish sees canned Pillsbury Grands atop a simple but delicious creamy chicken filling. Perfectly browned biscuits and a tasty, melt-in-your-mouth filling packed with chicken and veggies- yum!

Pot Pie is another classic chicken comfort recipe, but how about making a Chicken Pot Pie Casserole? Making the crust with crescent roll dough keeps this recipe easy while making that crust flaky and delicious! All that leaves is the filling, which is a simple and filling blend of veggies, potatoes, and chicken breast.

How to make our Chicken Broccoli Alfredo Bake
-
Separately prep all your casserole filling ingredients before mixing them together.
-
Transfer the casserole filling to the baking dish before adding a buttery crushed cracker topping.
-
Bake until heated through and topping has turned a golden brown.
Making the casserole filling is as simple as mixing everything together! First, we have to get everything prepped: start by mixing your alfredo sauce and milk together in a bowl. Once mixed, make your penne according to the manufacturer’s instructions before straining it off.
If not thawed already, thaw out your broccoli. With that, we can finally add our chicken, broccoli, and penne to the bowl with our alfredo sauce. Give that a gentle stir until everything’s well coated then transfer your filling to a greased baking dish.
To make the cracker topping, first, melt some butter in a microwave-safe bowl.
Crush up a sleeve of Ritz crackers before adding it to the bowl with the butter. Stir to combine and coat.
Sprinkle an even layer of your cracker topping over the casserole. Once topped, transfer to an awaiting 400 degree oven.
Let that bake until the filling is heated through and the topping is nice and golden-brown. This should take around 20-25 minutes but keep an eye on it- that topping can burn quick!
Once your casserole is all cooked, pull it from the oven. Let cool for a few minutes before scooping out a portion. Season to taste with salt & pepper and enjoy!
How long is Casserole good for?
If you happen to have any leftovers, either cover your baking dish with plastic wrap or foil or transfer contents to an air-tight container. Kept in the fridge this way, your casserole should stay good for about 3-4 days. I’d hesitate to freeze this casserole- alfredo sauce doesn’t freeze too well and that cracker topping might soften from freezing and thawing. Thankfully, it’s easy to make and those leftovers will be eaten up fast!

I made this chicken broccoli casserole last night and it turned out PERFECT! This recipe is amazing. Easy to follow and the taste was delicious. It will definitely become one of our family’s favorite recipes.
Can I use fresh broccoli?
Hi Mimi! I have not tried fresh broccoli in this casserole. I am sure it would take quite a bit longer to cook. If you give it a try, let us know.
Followed exact instructions, Loved the crunch texture on top. Creamy and satisfying. My husband and I both thought it lacked a little “something”
Can you suggest another liquid besides Alfredo sauce?
I am not fond of Alfredo sauce.
Thank you.
Hi Jan! YOu could try a tomato or cheese pasta sauce. Or consider using cream of chicken, celery, or mushroom soup too. I hope that helps a bit
