This Chicken Pasta Casserole is the perfect simple and freezable weeknight dinner. It’s delicious, loaded with nutritious veggies, and finished off with a crunchy and cheesy breadcrumb topping.
I’m a big casserole advocate. They’re so comforting and not to mention easy to put together. A casserole like this is also great for customization! This recipe is a great way to use up some ingredients hanging out in your fridge or pantry. Feel free to get creative and mix in any of your favorite ingredients.
This is a type of meal that also freezes really well! Make a few batches, freeze, and throw the casserole in the oven for an effortless dinner when you’re pressed for time. Dinner can’t get any easier than this!
This recipe is made with staples from your pantry and fridge. I’m sure you have almost everything you need waiting at home!
- Olive oil – You can use any other type of mild-flavored oil that you have handy.
- Elbow macaroni – You can use other small shapes such as penne, rotini, farfalle, etc.
- White onion – You can use red or yellow onion as well.
- Bell pepper – I used red, but you can use any type of bell pepper you want.
- Zucchini – Eggplant or yellow squash can be used if you can’t find zucchini.
- Chicken breasts – Thighs or ground chicken will work as well.
- Half & half – This is half milk, half cream. It’s usually around 10%. Coffee cream, regular milk, or heavy cream can be used in its place.
- Marinara sauce – Use your favorite type! You can also use homemade sauce.
- Cheese – This recipe calls for Parmesan and mozzarella.
- Breadcrumbs – I used panko for some extra crunch but any type of breadcrumb you have will work.
- Salt and pepper – Season to taste.
- Parsley – I love to use some chopped fresh parsley to garnish.
How to Make Chicken Pasta Casserole
- Cook the pasta: Cook the pasta according to package instructions. Drain and set aside.
- Cook the chicken & veggies – Heat the olive oil in a large skillet and add the chicken. Once it has cooked, add the onion, bell pepper, and cook until softened. Season with salt and pepper then add the zucchini.

It’s best to freeze this casserole before baking, but, of course, you can freeze cooked leftovers. Layer everything in the baking dish and wrap it well with both plastic wrap and aluminum foil before storing it in the freezer to avoid freezer burn. This casserole will last 2 months frozen.
