The Recipe Backstory

I don’t know if chicken spaghetti is just a southern thing or if it’s one of those dishes that’s popular all over the country. I don’t want to assume all of y’all know what it is so here’s a basic description…

If you took all of the mom hugs in the history of the world and stirred it together with cuddly sweaters and favorite jeans, then sprinkled a crackling fire and a good book on top you’d have an idea of just what chicken spaghetti is all about.

For those of you that lean to the prosaic things in life I’ll just say that it’s gooey and cheesy with a little smoky spice.

I honestly don’t remember the first time I had chicken spaghetti but I do know that it was one of my favorites when I was growing up. Since it’s such an easy, inexpensive dish I made it often for my own family as well. When I began eating low carb I’d watch the kids gobble down that glorious comfort food while I nibbled on my grilled chicken breast.


Obviously something would have to be done – so I played around until I think I got it just right – as close to real chicken spaghetti as you’ll get and still be low carb.

Nah. Actually it’s diced tomatoes and fire roasted green chiles. If you can’t get Ro*Tel you can replicate it with those ingredients.

  1. Substituted or omitted a few things I had/didnt have on hand and cut it down to 1 zucchini (all I had) with more chicken to zoodle ratio. Still pretty delicious dish. Thanks.

  2. This is my new favorite low carb recipe! Oh my gosh, it was amazing!!! Tastes better than the high carb pasta version.
