Chicken Spaghetti Casserole

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 this one up as much as I thought I could: Chicken Spaghetti Casserole

Chicken Spaghetti Casserole recipe : from

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.

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.

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

Chicken Spaghetti Casserole recipe : from

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.

Chicken Spaghetti Casserole recipe : from

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.

Since I’ve been using My Fitness Pal (tracking my calories and exercise), I went ahead and figured out the nutritional information for this one and have included that as well as weight watcher points within the printable recipe below.  It’s definitely not 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 had my serving, and that’s it!  Big side salad to go with.  Perfect, and it was filling and satisfying too!

Yield: 6 servings

Prep Time: 25 minutes

Cook Time: 35 minutes

Chicken Spaghetti Casserole


  • 7 ounces thin spaghetti
  • 1 tablespoon salted butter
  • 2 cups sliced mushrooms
  • 1 medium onion, chopped
  • 1/2 cup chopped celery
  • 1/2 cup chopped green bell peppers
  • 1/2 cup chopped red bell peppers
  • Two 10.75-ounce cans 98% fat free cream of mushroom soup
  • 1 cup nonfat milk
  • 8 ounces sharp cheddar cheese (reduced fat optional)
  • 2 cups cooked, chopped chicken breast
  • 1 teaspoon Tabasco sauce
  • salt and pepper, to taste
  • 1/2 cup shredded Monterey Jack cheese (reduced fat optional)


  1. Preheat oven to 350 degrees F. Spray a 2-quart casserole dish with nonstick spray.
  2. Cook pasta according to package directions, but only cook it until it's al dente (you still want a little bite to it). Drain the pasta and set it aside.
  3. Melt butter in a large, deep skillet over medium heat. Add mushrooms, onion, celery and bell peppers. Cook until the vegetables have softened, 4 to 5 minutes. In a medium bowl, mix milk and soup until smooth. Add this mixture to the vegetables in the pan. Stir in cheddar cheese. Continue to heat the mixture until the cheese has melted and the sauce is smooth. Add in chicken, pasta and tabasco, and season to taste with salt and pepper. Pour the mixture into the prepared casserole dish. Sprinkle Jack cheese on top.
  4. Bake for 35 minutes, or until the casserole is hot and bubbly and golden brown.


  • If you're trying to figure out a serving size for this casserole, simply use a knife to divide the pan into 6 equal servings. There's your serving size (it's pretty substantial)!
  • Leftovers of this casserole are great for a couple of days after making it.
  • Turn this casserole into a day-after- holiday meal by adding leftover turkey instead of chicken.
  • Nutritional Information per serving (Serving size: 1/6th of the casserole) Calories: 490, Fat: 22.5g, Saturated Fat: 12.3g, Sugar: 3.3g, Fiber: 2.7g, Protein: 31g, Cholesterol: 89.3mg, Carbohydrates: 39.4g

    I bet this would be really good made with tortilla chips instead of spaghetti – sort of like dinner chiliquillas (that seems to be a San Diego B-fast specialty). Or maybe corn tortilla strips.

    This dish is super yummy and quick! We usually use rotel (you know the tomato mix in a can right) and it’s even more quickly put together! However I like the idea of mixing up the veggies. Thanks

    I usually double this and freeze at least half of it. It makes a great dish for a covered dish supper or to take to the family when someone dies. Every time I take it anywhere one or two people asks for the recipe!

    This was super good. Make a huge meal. I was going to ask about freezing but someone answered my question. Casseroles and an extra meal doesn’t get better than that.

    I LOVE this recipe!! I’ve been making it for years, but I’ve out my own little twists on it. Instead of using regular spaghetti noodles I use penne pasta and I omit the celery. I also use Velveeta cheese instead of shredded cheese. Every time I make it I have to write the recipe down for at least one person who eats it.

    This looks amazing! I have a “chicken spaghetti” recipe as well, a bit like yours, but also a lot different! I would love to add those huge mushrooms to mine, but I don’t know if I could pass it off to my husband and 4 yr old! LOL

    This looks amazing. I am thinking about making this tonight minus the mushrooms and using whole wheat pasta. I think I will try the Cream of Chicken soup as well. My husband will love having this comfort food ready when he gets home tonight after a long day working Fat Tuesday downtown and my 13 year old son looked at the pictures and said he can’t wait to try it.

    This recipe sounds really good! I will certainly try it but I have just one question. By 8 ounces cheddar cheese, do you mean an 8 oz bag (about 2 cups) or 1 cup?

    • postedMar 10, 2014 6:22 AM

      Yes, 8-ounces of cheese is 2 cups. If you are measuring liquid, then 8-ounces = 1 cup.

    I have made another version of this several times before, but today I used your recipe. My son and I both enjoyed it. I like that your version adds plenty of veggies. I only have Almond Milk around these days, so I substituted Chicken Broth in lieu of Milk to loosen the Cream of Mushroom mixture. I stuck to the recipe besides the one substitution and it worked out great! I will definitely be making this version from now on. Hopefully I can find something else yummy on your site! Thanks a bunch!
