It was a revelation the first time I made Instant Pot mashed potatoes, and I rarely make them any other way. Below are the advantages to making Instant Pot mashed sweet potatoes: - eliminates the need to boil an entire pot of water. - reduces the cooking time and the amount of water used. - results in perfectly tender sweet potatoes every single time. - mashed sweet potatoes can be kept warm right in the Instant Pot.
