When I asked Facebook fans the other day about the possibility of me posting a new casserole recipe, I received an overwhelming response. It seems that there are a lot of casserole-lovers out there! I live in San Diego- not really the Casserole Capital of America. People here eat grilled chicken, tofu hot dogs and salad with no dressing. Casseroles are among the evils that aren’t spoken here in SoCal.

Whatever. I eat casseroles. Must be because all of my distant Swedish relatives live in Minnesota, where comfort food is more welcome. It’s in my genes. And probably my jeans too. The good news is that I lightened up this Chicken Spaghetti Casserole recipe as much as I thought I could.

This is quite the cheesy casserole, and I mean that in a good way. It’s hard to lighten up on cheese since low fat cheeses do not tend to melt nicely, so I charged straight ahead and used full-fat cheese for this recipe.

Don’t worry- you’ll see the calorie count in the end (which is actually not too terribly bad).  And you can always use low fat cheese, if you prefer.

What ingredients do you need for Chicken Spaghetti Casserole?

Here’s what you’ll need for this recipe. Yep, we’re doing something I rarely do on my recipe site: using Cream of Mushroom Soup. If that scares you, head over to Deliciously Organic and snatch Carrie’s homemade Cream of Mushroom Soup recipe, which looks pretty darn good.

How to Make Chicken Spaghetti Casserole:

Boil the pasta, just so it’s kinda al dente (still has a slight bite to it).

melting butter in a skillet

Melt 1 tablespoon of butter in a pan.  Just a tablespoon.  We don’t need a whole stick or anything like that since we’re just going to sauté the veggies in it.

Cook the veggies in that melted butter, just until they’re a little bit softened up.  Here’s where you can get creative.  If you don’t like my choice of veggies (or more importantly, if your family refuses to eat certain veggies), change it up and add in what you’d like.

There are Weight Watchers Points included at the top of this post. It’s definitely not “really” a weight watcher kind of recipe, but if you’re on that sort of a diet and you feel like splurging… at least you know the details and can plan for it.  I’m a firm believer in eating what you want on a diet… normal stuff in moderation.  That’s what I did with this recipe.  I like to have my one serving, and that’s it!  Big side salad to go with.  Perfect, and it is filling and satisfying too!

    We love this recipe. I added red bell pepper and the green bell pepper. I didn’t have the cheese that was called for so I used Mexican mix in with the soup and then on top I used mozzarella cheese. it was delicious and everyone liked it.

    Did you use a half cup each of green pepper and red pepper or a quarter cup of each?

    • Lori Lange wrote:

      It doesn’t matter so much, but 1/4 cup of each is fine. If you want more, add more 🙂

    This recipe is awesome. Nice made it several times for pot luck and funeral meals. I added an 8oz container of sour cream. I’ve also topped it with Mexican cheese blend to have a Mexican flavor.

    This recipe was great. I used a rotissori chicken from Costco. I also added a little cream cheese.  This is a keeper.

    OMG! I live in San Diego county and all I did to make it less comfort more California is substitute cooked cauliflower for the spaghetti and a mixture of half and half and sour cream for the soup! It was amazing! My husband eats low carb and loved it. Thank you soooo much.

    I made this recipe exactly as posted, it is excellent! Have you made it and baked it the next day? I didn’t know if the pasta would soak up the liquids if refrigerated overnight.

      I have not, and I might be worried about the same thing!

    I made this tonight with a few modifications and it was Absolutely delicious! I used ground chicken, almond milk (only 3o cal per cup) cheddar cheese made with 2% milk, and gluten free spaghetti. My Hubby has lots of allergies! It still turned out great!
