Chicken Casserole with Pasta

I love pasta in all its forms!  My family would eat spaghetti once a week if I let them, so I thought I would switch up our regular pasta-night dish for a pasta casserole.

My husband doesn’t typically like recipes with pesto, but this recipe had just the right amount of it.

How to Make Pesto Chicken Casserole

First, you’ll need to cook your noodles. We use penne pasta in this pasta bake, but any kind would work. We’ve tried it with bowtie and our kids loved that too!

  • In a large bowl, mix together all of the ingredients listed to assemble the casserole.
  • After you have mixed together the ingredients for the casserole, you spread them in a 9×13-inch baking dish.
  • Next, you sprinkle a delicious, cheesy crumb mixture on top and put it in the oven!

This chicken casserole recipe is extremely simple and takes no time at all to assemble!

Tips For How to Make a Chicken Casserole with pasta

Used canned goods: This recipe can be simple if you choose to use canned tomatoes, Alfredo, and pesto sauce. It’s almost a dump and go recipe that tastes amazing!

However, you can definitely use homemade or your favorite version of any of those mentioned above if you like to use fresher ingredients.

Cool Off Your Pasta: Make sure to rinse your pasta off in cold water after you boil it. This will keep it from sticking together when you’re trying to mix it with your other casserole ingredients.

Our best advice is to dump your pasta into a straining bowl like this one. And then run cold water over your pasta for 2 minutes. We promise you’ll notice a difference using cooled pasta rather than hot.

Homemade Pesto Sauce Recipe

We know not everyone loves pre-made pesto or Alfredo sauce, so using your own is totally fine. Here’s our favorite recipe for homemade pesto sauce:

  • 3 cups fresh basil leaves
  • 1 1/2 cups chopped walnuts
  • 4 cloves garlic, peeled
  • 1/4 cup grated parmesan cheese
  • 1 cup olive oil
  • Salt and pepper to taste

In a food processor, blend together basil leaves, nuts, garlic, and cheese. Pour in oil slowly while still mixing. Stir in salt and pepper.

  1. I agree, this recipe does make a lot, however, we eat leftovers at our house. We cook one day and eat leftovers the next day. So I'm always looking for recipes that is conducive to that. The two things I will do different the next time is add more Alfredo sauce so it will be creamier. I will add more pesto sauce. We hardly noticed any pesto and we all love pesto. I will definitely make this recipe again.
