My new Instant Pot Creamy Parmesan Garlic Mushroom Chicken is another rich and creamy decadent weeknight meal, which is also fancy enough for your most formal dinner party.

Tender chicken swimming in a rich and creamy garlic sauce with sauteed mushrooms and spinach will have you shouting from the roof tops.

This recipe is based on my Pressure Cooker Tuscan Garlic Chicken, which has been going viral for over two years.

So, if you enjoy that recipe, you will love this recipe too.

The creamy garlic sauce is nice and thick!

Ingredients for Instant Pot Creamy Parmesan Garlic Mushroom Chicken?

Chicken Breasts
Lots of Fresh Garlic- the more the merrier.
Cremini Mushrooms
Potato Starch or Coconut Flour
Extra Virgin Olive Oil
Butter
Shaoxing Wine
Chicken Broth
Salt
Pepper
Parmesan or Asiago Cheese – buy a whole block and grate it yourself

Slice Cremini Mushrooms and Mince Fresh Garlic

That’s a lot of garlic, no? The more the merrier, use as much as you like.

What are Cremini Mushrooms?

In a nutshell, they are basically baby portobello mushrooms.
Cremini mushrooms are also referred to as “baby bellas.”
The portobello mushrooms are a much larger and more mature version of a button mushroom.
The cremini mushrooms are also more mature than the button, but not near as large as the portobello.
They are browner in color with a firmer texture.
Their flavor is more woodsy than the button, which I find very bland.
All three types are part of the Agaricus Bisporus species.
Essentially, cremini mushrooms are simply the browner, older version of a white button mushroom.

Whisk together the Creamy Garlic Sauce

My Creamy Garlic Sauce is fantastic.

Grab a glass measuring cup and add all the ingredients and whisk them together.

This recipe goes quickly, so having all the prep work done is a good idea.

Keep the Creamy Garlic Sauce in the fridge until you are ready to use.

Prepare the Chicken with Starch and Seasonings

Why Use Potato Starch?

Chicken can be tricky and can turn out rubbery and tough.
Potato starch will help to lock in the juices and keep the chicken tender.
In Asian cooking, potato starch has been used for years and years in their recipes, especially for coating meat and then deep frying. This makes for a very crunchy fried or orange chicken, for example.
In my opinion, using flour in an Instant Pot, Mealthy MultiPot or Pressure Cooker is not the best option, as it can leave an uncooked taste. Plus, it is a pain to make a slurry at the end. Plus I really don’t like making starch or flour slurries, do you?
My “propriety method” is a 2-in-1 process, which keeps the chicken (or other type of meat) juicy and tender and eliminates the need for a slurry, when cooking under pressure.
I’ll call this my Starch Protection Method (“SPM”), just for fun. You can see this method through my blog.

Low Carb and Keto diets can eliminate this step or use coconut flour instead of potato starch!

In my Instant Pot Beef Stroganoff recipe, which uses beef, you will see how the SPM will keep the beef juicy and make a yummy thick cream sauce.

So, while your Instant Pot, Mealthy MultiPot or Pressure Cooker is heating up, prepare the Chicken for cooking.

Use a sharp knife and slice though the chicken breast to make two pieces. It is as if you are butterflying the chicken, but go all the way through to make two pieces.

A Super Quick Sauté

Once the Instant Pot, Mealthy MultiPot or Pressure Cooker has been preheated, you can begin the cooking process.

Only using a small amount of extra virgin olive oil and rich butter, the chicken gets a very quick sauté.

Seriously, just enough for the potato starch or coconut flour to stick, like 3-5 seconds a side.

The photo above shows the third piece of chicken I seared, so you can see not much starch gets stuck to the bottom of the pot.

There will still be enough fond for great flavor and, the pot will easily come to pressure.

But, we are going to deglaze anyway.

Plus, the chicken will have Starch Protection! Darn, I wish I thought of that term before I submitted my recipes for my cookbook, This Old Gal’s Pressure Cooker Cookbook. It would have been a nice term to use in my book.

Deglaze with Sherry or Shaoxing Wine

What is Deglazing?

It is the act of using liquid in a hot pot to remove anything stuck on the bottom of the pot.
The liquid poured into a hot pot will create steam and help to lift the fond from the bottom of the pot.
The fond is essential in adding more flavor to the overall recipe.
As the liquid heats up, grab a firm, high heat spatula and scrape the bottom of the pot, until nothing is stuck.

Why Deglaze with Sherry or Wine?

Sherry and Wine add a fabulous flavor to the fond.
If your recipe is good, it will be great if you use Sherry or Wine.
Sherry (for drinking) can be expensive, so Shaoxing Wine works just as well.
The difference is so minimal, it’s really not even worth discussion.
So, use a good drinking Sherry or Shaoxing Wine to deglaze.

When you deglaze the pot, most of the alcohol content will burn off and no one is going to get drunk. 🙂

Mushrooms and Garlic Cooked in Sherry and Butter

There is nothing better than cooking Mushrooms in Sherry or Shaoxing and butter.

Well, maybe onions and garlic too!

The flavor it adds to this Instant Pot Creamy Parmesan Garlic Mushroom Chicken recipe, as well as others, is incredible.

Chicken Broth joins the Party

My Pressure Cooker Homemade Chicken Broth is awesome in this recipe.

If you don’t have any on hand, try using some Better than Bouillon Chicken Base, mixed with fresh water.

I keep a big jar in my refrigerator for emergencies. The instructions say one teaspoon per cup of water, but I usually do 1.5 teaspoons per cup of water.

Return the Chicken to the Pot

There is a lot of liquid in the pot.

Don’t worry that it will be too much.

The chicken will release more liquid.

But, it is a good thing.

Remember the Starch Protection! (Too much?)

When you open the pot after pressure cooking, the liquid will be thicker than it is now!

Pour in the Heavenly and Rich Cream Sauce

You can see the liquid in the pot is already a bit thick and not runny at all.

This cream sauce is so delicious.

If you want to make a stand alone Cream Sauce to use it in other recipes, add potato starch and butter to it and whisk.

What Ingredients are in the Creamy Garlic Sauce?

Remember, earlier we used the butter to sear the potato starch coated chicken and then cook the shrooms? Those two ingredients would complete the above list for the stand alone creamy garlic sauce.

Mix in the Parmesan or Asiago Cheese

Can you see the thickness?

I heard your comments about wanting a thicker sauce in my Pressure Cooker Creamy Tuscan Garlic Chicken recipe.

I also heard you say you wanted more sauce as you loved my sauce so much.

You will have plenty of sauce in this Instant Pot Creamy Parmesan Garlic Chicken Mushroom recipe.

We had enough sauce leftover to make a meal of just shells and sauce and there was still sauce left!

We are just two people, so there was enough sauce leftover to serve four people with shells and sauce. Let me tell you, it was even better the next night.

No need to add cream cheese or anything else.

Do yourself a favor. Buy a block of Parmesan or Asiago cheese and use a grater to grate it yourself. The packaged pre-shredded cheese is kind of flavorless and coated in something to keep it from sticking.

Add as much Spinach as you like

Fresh Spinach finishes off the recipe.

I used two cups, maybe more, I just kept adding and adding.

Feel free to use as little or as much as you like!
