What is Chicken Alfredo Bake
Chicken Alfredo Bake is similar to the traditional chicken alfredo pasta, but baked in a casserole dish.
We love this dish for so many reasons. First, alfredo sauce is one of my kids favorite pasta dishes. Second, I can make a big batch of this in the afternoon and throw it in the oven right before we are ready to eat! Finally, leftovers! There are always leftovers and they make a great lunch the next day or dinner another night during the week!

How to Make Chicken Alfredo Bake
Prepare pasta to al dente and set aside.

In Dutch oven, melt butter over medium heat. Add cream cheese. Use a whisk to stir.

Add minced garlic, garlic powder, onion powder, black pepper, and Italian seasoning. Whisk until mixed and butter/cream cheese are melted.

Add flour and mix well. Add the heavy whipping cream one cup at a time, continue to stir. Add milk.

Add one cup of mozzarella cheese and one cup of parmesan cheese – stir to mix and melt.

Once all the sauce is melted – stir in chicken and pasta.

Pour in 9×13 pan that has been sprayed with nonstick spray.

Top with remaining one cup of mozzarella and ½ cup of parmesan cheese.

Bake for 10-15ish minutes to melt cheese. Turn on the broiler for a couple minutes to brown.

Making Chicken Alfredo Bake In Advance
I know I have mentioned how much I love this recipe for its easiness, but what if I told you it can get even easier? I love to make this recipe in advance, freeze it, and pop it in the oven on the night when I’m ready to serve it. This saves me even more time on busy school nights.
If you want to make it in advance and freeze it for later you have a couple of options. You can follow all of the instructions above, and freeze it after baking. Then, when you’re ready to serve it you simply let it thaw and reheat it in the microwave or oven.

Alternatively, you can follow all instructions up until the point of baking and freeze it unbaked. Then when you are ready to serve it, you will want to let it thaw and follow the instructions from the point of baking until the end.
How to store Chicken Alfredo Bake
If you make it in advance you can store it in the freezer until you are ready to serve! Another option is to make this one day in advance and simply store it in the fridge overnight, and bake it the next day!
As for the leftovers, you can simply put a lid on it or put tin foil over the pan and store it in the fridge.
What to Serve with Chicken Alfredo Bake
There are so many great options that pair well with this Chicken Alfredo Bake! I love to make yummy garlic bread or our Easy Cheese Stuffed Garlic Rolls rolls as a bread option.
Another great addition to this dish is to start out with a garden salad or to pair some roasted veggies or green beans on the side.
