The Keto Chicken Spaghetti 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 with spaghetti 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. This keto recipe is as close to real chicken spaghetti as you’ll get and still be low carb.

Low Carb Chicken Spaghetti FAQs

This is an easy keto recipe. Especially if you can get the zucchini already spiralized at the grocery store and pick up a rotisserie chicken from the deli section at the grocery store.

How do you make low carb chicken spaghetti with Rotel?

Ro*Tel is really the secret ingredient in this chicken spaghetti recipe. Whether you do low carb or just eat a regular diet. It doesn’t have many carbs and it adds just the right amount of zippity-do-dah to what “could” end up being too bland of a dish. Besides, it’s a traditional part of this dish for me growing up. This is such an easy dish to make that you can make it on a busy weeknight. Here are step by step images followed by step by step instructions to make sure you make an amazing main dish.

What’s in a can of Ro*Tel?

Pure magic.

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

What can I do with leftover Ro*Tel?

Since I try to keep the low carb recipes here on Lowcarb-ology down to 1 or 2 servings you might often have half a can of Ro*Tel left like in this recipe. Here are some more recipes from Lowcarb-ology using small amounts of Ro*Tel or where you can substitute Ro*Tel.
