Keto Chicken Tetrazzini

This is one of those recipes that I even surprised myself on. I mean, I knew it would be amazing and come together beautifully, but I didn't know that it was going to be AS amazing as it turned out.

Long before Keto I was Paleo and long before Paleo I was a pasta lover.

Chicken Tetrazzini was one of my favorite meals. I has mostly written it off because while I love zoodles, they can only go so far in terms of replacing some of my favorite meal bases.

Enter..... palmini noodles.

Now, this was my first attempt at using the linguini style palmini noddles. I've used the lasagna noodle ones before and OH MY - they were amazing.

So I already knew this recipe would be good. But brace yourself, because I think it is going to knock your socks off!

What Are Palmini Noodles Made Of?

Palmini noodles are made from hearts of palm. If you never tried hearts of palm before, you are in for a treat!

The best way to describe them is like a firmer artichoke heart, but with a tang. And 100 times better!

They also only have 2 net carbs per serving and you simply can't beat that.

If you are sick of using zoodles to replace your linguini or spaghetti noodles, then these will become your new favorite!

How to Store Keto Chicken Tetrazzini?

That is assuming you actually have leftovers. I fully expected to have leftovers, but my non keto husband pretty much licked the pan!

However, as with most casseroles, you will want to store this in an air tight container in the fridge. These types of casserole recipes easily last 3-4 days if stored properly.

Is Chicken Tetrazzini OK on keto?

The keto version, of course!

But regular chicken tetrazzini is generally made from wheat noodles. And even if it is made from gluten free noodles, the carb count will most likely be too high.

This is what makes THIS gluten free chicken tetrazzini recipe so special. It is low carb AND gluten free. Palmini noodles will soon be your best friend.

Can I Add Mushrooms?

Yes, you certainly can.

I know, I know, most chicken tetrazzini recipes are made with mushrooms. I just cannot stand the taste (or lack thereof??) of mushrooms. Never been a fan.

I do know that there are plenty of mushroom lovers out there though, so feel free to throw them in!

How To Make Keto Chicken Tetrazzini

Preheat the oven to 350 degrees F and grease an 8x8 baking dish.

Heat the butter and olive oil in a frying pan over medium-high heat.

When the butter is melted, add the onions and saute for 2-3 minutes. They will begin to soften and become translucent.

Add the minced garlic and saute them for an additional 60 seconds.

Once the garlic is fragrant, add the Italian seasoning, xanthan gum, chicken broth and heavy whipping cream. Mix well.

Cook the mixture down until it begins to thicken. This will be about 5 minutes.

Add in the mozzarella and parmesan cheese, and cook until the cheeses are melted and the sauce is thick. Stirring often.

Mix in the chicken and the palmini noodles. Continue stirring and cooking for an additional 2 minutes.

Add mixture to a greased 8x8 casserole dish.

Bake uncovered for 30-35 minutes, or until the chicken tetrazzini begins to brown and bubble.
