  5. Saute setting: Open the instant pot carefully, and remove the spuds, the trivet, and discard the water. Then, add the bright orange flesh of the spuds back to the bottom of your instant pot. Select the Saute mode and then, add in the rest of the ingredients except for the topping ingredients. Stir veery well to combine.

Are Sweet Potatoes Healthy?

It is a kind of tuber in which the roots become the edible part of the plant. It is like the regular spuds, but the leaves are edible, too, while those of the regular spuds are poisonous.

Around the world, it is known to be a staple food. It grows abundantly even in drier regions. In fact, it can get damaged by frost.

This type of spud has fewer calories than regular ones despite having more sugar. This makes it ideal for people trying to lose weight as it is not bland, and yet, it is packed with vitamins, nutrients, and antioxidants. It is rich in vitamin A and it also has a lot of fiber that helps digestion.

What is a Natural Pressure Release?

It is when you wait for the pressure to naturally dissipate, hence, the name Natural Pressure Release or NPR. This is done by simply waiting for the valve to float without initiating to move it. When you open the pressure valve to release the steam, it is called a Quick Release.

How long do you pressure cook sweet potatoes?

This depends on the amount and size of the spuds. Usually, the 14-minute pressure cooking time indicated in this recipe pertains to cooking about two pounds of the vegetable.

Allow another 10 minutes for the pressure to build up, and another 10 minutes for the NPR. So, plan ahead using these estimates!

How to store leftovers:

  • Refrigerate: First, let the leftovers fully cool and after that add them to an airtight container. In the fridge, they will stay good for 3 to 5 days.
  • Freezer: To extend the shelf life, you can freeze the leftovers and it will stay good for up to 3 months. Put them first in freezer bags or plastic containers with a sprinkle of lemon juice or lime juice to prevent them from oxidizing and discoloring. Also, cool completely before storing.
  • To reheat: Thaw in the fridge overnight and it will keep good for 3 to 4 days but if thawed directly using the microwave or in water, consume immediately.
  • Reheat: The easiest way to reheat the leftovers is by using the microwave or the stovetop. In addition, add a little bit of cream or whole milk if needed and adjust for salt and ground black pepper.

Cooking Tips:

  • If you do not have heavy cream, you can use any of these: sour cream, buttermilk, milk, or half-and-half. All these contribute to a creamy dish!
  • A masher is preferred but to make it silkier, you can use a food processor to mash. If you have none of these things, using a fork would be okay.
  • To determine whether the spuds are soft enough, use a fork. You must be able to prick the pieces effortlessly.
