- Wash and dry the fresh, raw, whole sweet potato.
- Poke small holes in the fresh, raw sweet potato flesh with a paring knife or fork. You only need to poke it three or four times, just enough for steam to escape.
- Add your uncooked sweet potato that now has a few small holes to a microwave-safe plate or bowl, or just set it on top of a paper towel.
Without these small holes, the potato may burst while cooking, getting sweet potato all over the inside of your microwave and then maybe leaving you without your lunch.
We like seasoned sweet potatoes, so our recipe below will show you how to coat your sweet potato in oil and sea salt.
But you can also wait until it is done cooking before adding anything to it.

How Long Does It Take To Cook A Sweet Potato In The Microwave?
The cooking time varies, depending on the size of the potato and the cooking power of the microwave.
However, the general rule of thumb is that a medium-sized sweet potato, weighing around 8 ounces, cooks around five minutes on 100% power.
As there is no hard and fast rule in regards to the cooking time, it is best to cook large sweet potatoes in 30-second increments after the first five minutes.
Tips For Cooking Food In The Microwave
We have a 4Ts method of microwaving food that we’ve learned is a good way to end up with the best outcome for evenly heated food because microwave oven power varies so much, and the size and density of food can be so different.
“Turn, Time, Test, Taste”:
- Turn food over halfway through total cook time.
- Watch the time because it’s so easy to overheat food, especially when reheating.
- Test vegetables for doneness with a poke.
- Taste to make sure it’s adequately heated through.
How To Store A Microwaved Sweet Potato
Now that you know how to cook a sweet potato in the microwave, let’s take a look at how to store a microwaved sweet potato.
Pro Tip: It’s important to bring hot foods to room temperature before putting them in the refrigerator.
Here are tips for storing a microwaved sweet potato:
- Let the sweet potato cool completely before storing it. This will help to prevent the growth of bacteria.
- Cut the sweet potato into small pieces before storing it. This will help the sweet potato to cool more quickly and prevent it from browning.
- Cooked sweet potatoes will sometimes “sweat”—their sugary flesh breaks down into a syrup-like material. It’s still okay to eat as long as it is not older than three days and has been chilled properly.
- Store the sweet potato in an airtight container or bag. This will help to prevent the sweet potato from drying out.
- Refrigerate the sweet potato for up to 3 days. After 3 days, the sweet potato may start to lose its flavor and tender texture.
How To Tell When A Sweet Potato Is Cooked All The Way
If you can easily pierce it with a fork or slide a knife all the way through the skin of a sweet potato to the center of the potato, your sweet potato is ready to eat.
If it gives resistance after only a ⅓ of an inch or so, it needs to keep cooking.
You want it to be fork-tender.
Cook the sweet potato in bursts of 30 seconds or so after the initial five minutes on high.
Check the vegetable after every minute or two of cooking to see if it is cooked all the way.
You can tell when a sweet potato is cooked all the way when you pierce it with a fork or knife and the utensil slides a full two inches or more easily into the flesh of the potato.
Should I Wash My Sweet Potato Before Cooking It?
Yes, especially if you are eating a whole sweet potato from its fresh, raw state.
It is recommended to wash the sweet potato before cooking it even if you plan on removing the skin later.
Can I Microwave More Than One Sweet Potato At A Time?
Yes, it is possible to cook multiple sweet potatoes simultaneously.
However, you will have to add 3 minutes for each additional vegetable.
So, for example, if you are cooking two sweet potatoes, you should set the timer for 9 minutes (original cooking time of 5 minutes + 3 minutes for the additional sweet potato).
To heat evenly, most food cooked in the microwave should be turned over at least once during cooking.
(Even when you have a turntable that spins the food slowly.)
What Are Some Good Sweet Potato Toppings?
Use a mixture of protein, veggies, and cheese to top your microwaved sweet potatoes and turn them into a full meal or lighten it up for a quick snack.
Remember, you can top leftover sweet potatoes, too.
Here are some ideas for sweet potato toppings and delicious fillings.
- Bacon, onion, and rosemary topping
- Any nut butter (like almond butter, some decadent Nutella, or cashew butter) and agave
- Sour cream
- Feta cheese and paprika
- Thai curry paste and coconut milk topping
- Chopped pecans and maple syrup topping
