Baked Cheesy Chicken Spaghetti (Freezer Meal)

Spaghetti, colorful chopped vegetables, lots of cheese and…. canned condensed mushroom or chicken soup! But don’t be afraid. Baked cheesy chicken spaghetti is the perfect economical batch cook recipe and the ULTIMATE in tasty comfort food. The whole family will love it!

I came across the idea for this cheesy baked chicken spaghetti years ago while watching a rerun of The Pioneer Woman. If you’re ever feeling a little down, watch an episode or two of The Pioneer Woman and you’ll cheer yourself up in no time!

Ree has a way of making everything she makes look incredible, but she’s particularly good at these sorts of cozy, oozy, cheesy casseroles.

This is my slightly tweaked version of the dish!

Why you’ll love it

Just had a baby? Or perhaps you or your child is sick, you’re having an extra busy week, or you’re just feeling lazy today. There are times when we all want to grab a meal out of the freezer instead of making something from scratch.

This easy chicken spaghetti casserole is perfect for those days!

Here are more reasons why you’ll love it:

✔ It’s one of those fail safe recipes that everyone enjoys. It’s creamy, satisfying, nutritious and tasty – the ultimate comfort food!

✔ And yet it’s simple enough that even your pickiest kid (or grown-up!) will approve. This is one of the best freezable meals I know, but also one of the best kid-friendly freezer meals I know!

✔ It’s a very economical recipe – perfect for big families or a small crowd! You can easily feed 8, and up to 12 with simple salad or vegetables on the side.

✔ It’s the perfect make-ahead meal. I usually make a whole batch, portion into several casserole dishes, and freeze for lazy days when I don’t want to cook.

✔ Made with just a few simple and cheap pantry ingredients. Add more vegetables if you like, or optional extras for even more flavor (see below for variation ideas!).

✔ Reheats beautifully the next day. Leftovers make quick and tasty lunches!

Ingredients

Chicken: I prefer to use boneless skinless chicken thigh chopped into small pieces. If it’s available I get ready chopped to save time. You can also use chicken breast. Shredded cooked rotisserie chicken works, too, or leftover chicken or turkey. However, I do prefer to cook the chicken myself if I know I’m going to be freezing some of the casserole.

Chopped peppers and onion: I love to grab one red, one yellow and one green pepper for this recipe, but you can use any kind of peppers you like. A regular large white onion is fine.

Add even more chopped veggies if you like. Any vegetables that cook in about the same time as peppers work, such as zucchini, celery, asparagus, or green beans. Frozen vegetables such as peas, sweet corn and carrots can work, too (no pre-cooking required!).

Mushrooms: Any kind are fine, but the tastier the better (try brown, cremini, or a mushroom medley).

Spaghetti: You can use any kind of spaghetti you like. Just follow the cooking instructions on the package to pre-cook it. Cook the pasta so that it’s ‘al dente’, which means firm or, literally, ‘to the tooth’ in Italian! If the package doesn’t say, simply cook it for a couple of minutes less than the suggested cook time.

I prefer to snap the spaghetti into 3 shorter strands as I add it to the boiling water. Of course, also feel free to use different kinds of pasta noodles for this such as fusilli (twirls) or penne (tubes).

Dried Italian herbs: Or any dried herbs.

Pepper: I like to add plenty of ground pepper. You can adjust the amount to taste, even skipping it altogether if you’re serving the meal to kids. I don’t usually add salt because I find there’s enough already in the broth and cheese.

Condensed soup: Yes, you could consider this ingredient to be a little ‘retro’. But it’s perfect for this baked chicken pasta – quick and easy (just open the cans!), creamy and flavorful and, of course, kids love it. Use chicken soup, mushroom soup, or a combination of the two.

Chicken broth/stock: I try to use good quality, but feel free to use whichever brand you have or like.

Grated cheese: For maximum cheesy flavor, I usually go for a sharp cheddar. For even more cheesy goodness, how about adding a sprinkle of parmesan cheese on top of the casserole as well?

How to make it

The step-by-step guide below should help you make the recipe perfectly first time. Scroll down to the end for the full recipe including ingredient amounts.

The first thing to do is to sauté the chicken pieces in a little oil until white and cooked through. Then empty both the chicken and any juices into a bowl and set aside while you cook the veggies.

Next, add a drizzle more oil and cook the peppers and onions, just until softened.

Then add the mushrooms and cook for a few minutes longer, before also stirring in the dried herbs.

At the same time as you’re cooking the chicken and vegetables, you can boil the spaghetti. When it’s done, simply drain and empty back into the saucepan with a drizzle of oil to stop the spaghetti noodles sticking.

At this point, toss the cooked vegetables and spaghetti with all of the other ingredients. Toss really well!

You’ll want to save about a cup of the cheese for sprinkling over the top! If you’re making several smaller casseroles, you might want to sprinkle over even more cheese.

Then it’s time to empty the chicken spaghetti mixture into baking dishes. I usually portion it out into several dishes – one for that day’s dinner, and the rest for freezing. I find the best way to do this without getting spaghetti all over the kitchen is with two wooden spoons!

You can either bake immediately, or you can cover at this point and store in the fridge to bake later or even freeze for another day. If baking now, your delicious oven baked chicken pasta is ready when it’s bubbling and nicely golden on top (around 30 minutes).

Look at that transformation! Mmm!

How to serve

To make this cheap and easy chicken spaghetti recipe even more the classic comfort dinner it is, a fresh crisp salad and perhaps some garlic bread is all you need to go on the side.

This refreshing Greek lettuce salad could be a good option to balance out the creamy spaghetti carbs!

If you prefer to serve it with a vegetable side, consider this simple frozen green bean recipe!

Simple pan-fried asparagus, sugar snap peas or even cherry tomatoes are more great options that only take minutes to prepare.

Strictly speaking, you don’t need to serve anything at all with your casserole. Serving something very simple with it, however, both balances out the plates and makes the meal stretch even further!

Variations

I can think of a few ways to switch up this very easy chicken spaghetti bake!

• Add more and/or different vegetables. Any veggies that cook quickly are good choices, such as asparagus, zucchini, tomatoes, snap peas, celery, spinach, or frozen vegetables such as peas or corn.

• Stir in a quarter to a half cup of jarred marinated vegetables such as sundried tomatoes (or just cherry tomatoes), artichokes, capers, anchovies or chopped olives before baking for extra flavor.

• Add a can of Rotel (chunky tomatoes and green chilies) for a spiced up version!

• Add porcini mushrooms (and any soaking juices) for extra mushroom flavor.

• Try the recipe with leftover Thanksgiving or Christmas turkey and ham, or how about canned tuna?

• Try the recipe with a different condensed soup flavor such as tomato or french onion.

• Add a quarter cup of pesto, either regular or red.

• Use 3 tablespoons of fresh herbs instead of 1 tablespoon of dried. Or sprinkle fresh herbs such as parsley or chopped green onions over the top of the finished baked spaghetti.

• If for any reason you can’t find condensed soup to use in this recipe, feel free to substitute with jarred alfredo sauce, pasta sauce or similar.
