How to Keto Chicken Marsala

Start by turning the Instant Pot setting to sauté. If you don’t have the Instant Pot, the Ninja Foodie or other pressure cooker works just as well.

Next, add in the the olive oil and allow it it to heat it slightly. Next, add in the chicken, basil, salt and pepper, and sauté about 3 minutes on each side.  

Remove the chicken and set aside.

Add the butter to the heated pot and allow it to melt. Add in and sauté the mushrooms.

Allow them to get some good color, then remove and set aside.  Add in the garlic and sauté for 20 seconds, careful not to burn it!

Deglaze the pot with the marsala wine, scraping up the brown bits on the bottom.

Stir in the chicken stock and most of the parsley (reserving some for garnish), then add the chicken and mushrooms back in.  Turn off the instant pot and set to pressure cook for 10 minutes, then instant release the pressure.

Remove the chicken and mushrooms, then set the Instant Pot back to the sauté setting.

Stir in the Mascarpone cheese, heavy cream and Xanthan gum.

Then add the chicken back in and cook an additional 5-8 minutes or until thickened.

At this point and before I serve it, I taste the sauce and make sure it is salted enough. Who am I kidding, I just taste it to be tasting it and you’ll want to as well when that amazing aroma begins to fill your kitchen.

Serve with your favorite veggie or zucchini noodles and enjoy! A good pasta substitute that I recently started using is Palmini Noodles and I have to say it has become my favorite.

Palmini Pasta is made from hearts of palm. When cooked, it resembles linguini with a very similar al dente texture. But here is the great thing, with only 4 total grams of carbs compared to 42 carb grams in a traditional serving of pasta it makes an incredible pasta substitute.

And the great thing about it is it comes in different widths. They have Palmini Linguini size noodles and they even have Palmini Lasagna sized noodles.

What is the Best Wine to use for Chicken Marsala?

As in the name, Marsala wine gives this dish a distinct robust flavor. However, there are other wines you can use in its place. You will want a dry red wine like Madeira or port.

Alternately, if you choose to not use wine at all, you can add an equivalent amount of additional chicken stock.

Is Instant Pot Chicken Marsala Keto?

It sure is. It’s primarily healthy fat and protein. Along with the added nutrients from mushrooms and zucchini noodles and with only 2 net carbs per serving, those on Keto or a low carb diet, could consider the perfect meal.

How Do I Thicken Chicken Marsala?

In this recipe, Mascarpone cheese and Xanthan gum is used thicken the sauce in place of flour as found in the traditional recipe. You could also use cream cheese, but that does effect the carb count and it also gives the sauce a bit of a tangier flavor.

If you find that your sauce is still a little loose, add a little more Xanthan gum, but be very careful because a little bit goes a long way.

Can I Freeze Keto Chicken Marsala?

Because this sauce in this Instant Pot Chicken Marsala is made with heavy cream and Mascarpone, it’s best when served fresh. However, if you have leftovers, you can freeze it. Just store in an air tight container for up to a couple of months.

To reheat Instant Pot Chicken Marsala, thaw it in the fridge over night first. Then, before you’re ready to serve, reheat slowly stove top as you whisk the sauce to reincorporate the cream with the other ingredients.

The Instant Pot model that I have is the Instant Pot DUO80 8 Quart 7-in-1 Multi- Use Programmable Pressure Cooker, Slow Cooker, Rice Cooker, Steamer, Sauté, Yogurt Maker and Warmer
