Low carb chicken tetrazzini made with spiralized zucchini on an art deco plate. Title image

I came up with this recipe years ago for my other blog, Restless Chipotle. Of course, for that blog, I made it the normal way with pasta and a flour thickened sauce. I?ve been updating recipes over there and when I saw this one my brain and stomach got together and informed me that THIS was dinner.

It just sounded SO good!

The result was a perfect adaption of my high carb casserole ? I had my friend, also on low carb, try it and she loved it, too.

Don?t you love it when a plan comes together?

Zoodle FAQs

Have zoodle questions? I have zoodle answers!

How do you make zoodles?

Zoodles are made with a spiralizer, often using zucchini as an ingredient but other veggies can be used, too. There are inexpensive, hand held spiralizers but I love my Kitchen Aid attachment – it spiralizes the zucchini in seconds! More about that later.

How do you cook zucchini noodles?

You can microwave them, fry them, boil them, or steam them. I find that when I am making a dish with a sauce like this one it’s best to just but the raw zoodles in the sauce and let it simmer for a minute or two. If you cook them too long they will be mushy.

How can I make zucchini pasta without a Spiralizer?

If you don’t have a spiralizer all is not lost. 🙂 You can easily use a vegetable peeler to make wide “noodles” like I did with my low carb zucchini pappardelle.

Can you freeze zoodles?

You cannot freeze zoodles – they turn to mush.

Southwestern Chicken Tetrazzini Troubleshooting

My Chicken Tetrazzini sauce got watery!

This is an easy recipe as long as you follow directions carefully. It’s hard to gauge exactly how much water is in zucchini – it can vary a lot. Sometimes if you cook it too long it will release a lot of water, too. If your sauce gets watery after you put the zucchini in, take it out and put it in the baking dish. Simmer the sauce until it reduces and thickens up and pour it over the zucchini.

My sauce isn’t getting thick!

If your sauce doesn’t seem to be thickening up you can add a little more cream cheese and simmer it on low heat until it reduces and thickens. Remember to keep stirring!

I don’t like spicy food!

If you don’t want the sauce to be a little spicy then subsitute plain Monterey Jack cheese for the Pepper Jack cheese and leave out the poblano.

Thanks so much for being a part of Lowcarb-ology!
This is the spiralizer that I have. If you buy spiralized vegetables in the store they can be expensive but when you can do it yourself the spiralizer pays for itself in a matter of weeks!

    Made this today, absolute hit! Used cheddar and mozzarella cheeses, red pepper flakes, and my cilantro was dry, but added cut up green vegetable leaves for the effect..this one is for keeps, beats the restaurant favourite I have yearned since they stopped making theirs! Oh, also used Shirataki Noodles-A.M.A.Z.I.N.G!
