Instant Pot Cooking For Thanksgiving

I get asked every Thanksgiving how to cook multiple dishes with only one oven. The answer is if you are in charge of hosting Thanksgiving, utilize an electric pressure cooker or Instant Pot.

The Instant Pot not only saves you oven and stovetop space, it can keep food warm for long periods of time and save you time. Just utilize that keep warm button function after cooking.

This method definitely comes in handy if you only have one oven. You can make many things in the Instant Pot including vegetable sides, or even your turkey.

My favorite way to utilize the Instant Pot on Thanksgiving is definitely mashed potatoes.

Mashed Potatoes come out perfectly creamy and can stay warm in the Instant Pot so I can move on to another task.

Common Mashed Potato Questions:

Now that you have some more Thanksgiving inspiration, lets get going on these mashed potatoes. Here are some common questions and answers you may have while making this recipe.

Secret Ingredient:

So how do we get that garlicky flavor that is so coveted in mashed potatoes?

Most garlic mashed potato recipes call for garlic powder, raw chopped garlic, or even roasted garlic. But I like to use a secret ingredient instead.

The secret ingredient for these Instant Pot mashed potatoes is Boursin Cheese. Boursin cheese is a flavored soft cheese. There are different flavors, but my favorite and the best flavor for these garlic mashed potatoes is the garlic and herb flavor.

Boursin cheese adds a rich creaminess and a big punch of flavor.

What potatoes to use for mashed potatoes:

Many varieties of potatoes work well for mashed potatoes. Some of the best potatoes to use for mashed potatoes are Yukon gold potatoes or red potatoes. Stay away from baking potatoes such as russet potatoes as they will absorb a lot more water when cooking.

The Yukon gold and red potatoes have a thin skin so you don’t have to peel them. If you want a perfectly smooth mashed potato than peel the skin off all varieties.

How to cook mashed potatoes in the instant pot:

  1. Wash the potatoes. Cut the potatoes in 1 inch chunks.
  2. Place thee potatoes into the instant pot with 1 cup water.
  3. Seal with the lid and move the valve to the sealing position. Turn on manual high pressure for 10 minutes.
  4. Manually release pressure by moving the valve to the venting position (this is called a quick release) and add flavorings of choice. Today we are using our Boursin, but if you want plain mashed potatoes you can add butter and sour cream.
  5. Add the heavy cream and mash with a potato masher or use a hand mixer.
  6. Lastly salt and pepper to taste.

How to make mashed potatoes ahead of time:

Cook the mashed potatoes according to recipe directions. Turn the instant pot on warming mode and cover with the lid.

As the mashed potatoes sit they will absorb the liquid and get thicker. You may need to add some fresh cream or milk to thin the potatoes when you are ready to serve.

Are mashed potatoes gluten free:

Most mashed potato recipes are gluten free. Always check the ingredients to make sure there is no hidden gluten.
