Sweet Potato Instant Pot Recipe FAQs
Whether you're using regular sweet potatoes, Red Garnet yams (aka red sweet potatoes), or other types of yams, you'll cook them the same way in this recipe. The Red Garnet yams/sweet potatoes are our favorite since they have the best flavor.
How long it takes for sweet potatoes to get tender depends on their size, whether you’re cooking them whole or cubed, and also the cooking method you’re using.
Boiling: Boiled Sweet Potatoes If you're boiling sweet potato cubes, they should be tender in about 20-25 minutes.
Air Frying: Roasted Air Fryer Sweet Potato Cubes If you're using an air fryer, cook the sweet potatoes cubes in a preheated air fryer at 380°F for about 15 minutes, depending on the size of sweet potatoes you’re using.
Baking: A whole baked sweet potato in a 425°F (220°C) oven will typically take between 45 minutes to an hour to become tender.
Microwaving: If you're in a hurry, you can "bake" a sweet potato in the microwave in about 5-8 minutes, depending on the size of the potato and the power of your microwave. Always pierce the sweet potato with a fork a few times before cooking.
Slow-Cooking: If you're using a slow cooker, a whole sweet potato can take between 2-4 hours on high or 6-8 hours on low to become tender.
Sweet potatoes do become sweeter as they cook since the starches breakdown into maltose, which a type of sugar. This process, known as caramelization, is definitely more noticeable when sweet potatoes are roasted or baked at high temperatures. The heat causes the sugars in the sweet potato to "caramelize," giving them a sweet, slightly nutty flavor. However, overcooking sweet potatoes can result in a mushy texture and can also lead to burnt or overly caramelized sugars.

We used 5 lbs for a sweet potato casserole, you can scale that back to as many as you need for a recipe or as a dinner side. You'll still want to put 1 cup of liquid in the bottom of the pot regardless of how many potatoes you're cooking.
If you don't have a recipe in mind, you can mash the sweet potatoes and then add butter or oil, and salt and pepper to taste.
You can use the rack that came with your pressure cooker if you don't have the steamer basket, you just want to make sure to keep the potatoes out of the water so they don't get soggy during cooking.
The cooking time will be the same whether you need 2 lbs of cubed potatoes or even 5 lbs.
This same process can be used with Russet or Yukon potatoes to make mashed potatoes.
Donna says
So, since my Duo has a max pressure time of 4 minutes, I should restart it two more times?
WholeLottaYum says
Hi Donna! Yes, I'd do it in increments so 4 mints, then 4 minutes again, and check the potato consistency, and then add a couple more minutes. It'll come back to pressure very quickly.
Leo says
In addition to all the healthy benefits the author mentions there is one other: low glycemic index. Boiled sweet potatoes have a low GI at around 42, the longer you boil the lower the GI, and I see no difference between boiling and steaming. On the other hand, a baked sweet potato has a GI as much as 94, not much difference than white bread which is used in some circles as a reference to scale the index. It's all about starch structure.
