Lay the potatoes on top of the trivet. It's ok to stack the potatoes; the steam in the Instant Pot will cook them thru and thru.
Place the lid on the Instant Pot, seal the vent, and press Manual mode, setting to high-pressure cook for about 15 minutes. If your sweet potatoes are larger, they'll need more cooking time.
Allow the pressure cooker to naturally release pressure for 10 minutes.
Then manually release any remaining pressure. Just be careful of the steam, so it doesn't burn your fingers.*
Carefully remove the lid, and remove the sweet potatoes to a cutting board or plates.
Serve with butter or other toppings of your choice.*
*Tip: To manually release the valve, I like to use the long handle of a wooden spoon covered in a kitchen towel, with my hand under the towel on the other end of the spoon. *When it comes to topping your baked sweet potatoes, the sky's the limit. Here are some simple ideas to serve your sweet potatoes in a manner that your family will be sure to enjoy!
Spread butter, salt and pepper for a savory snack, much like a regular baked potato. You could even throw on some sour cream and chives!
Throw some marshmallows on top. This would pair wonderfully with the brown sugar and cinnamon, and you could even throw some pecans on top to imitate a traditional sweet potato casserole.
Finish them off in the oven with some melted cheese; cheddar, Monterey Jack, Colby Jack, mozzarella, Asiago, and even grated parmesan cheese would all be wonderful candidates. You could even add caramelized garlic and onions and sliced tomatoes to this mixture.
Make taco stuffed sweet potatoes! Split the potato open, add your taco meat (taco beef or taco chicken), salsa, cheese, and all of the normal taco fixings.
