Boiled sweet potatoes are a familiar dish that can be a main course or a snack. While boiling sweet potatoes is simple, there are some tricks to ensure they cook evenly, taste sweet, and have a soft texture.
Selecting Fresh and Delicious Sweet Potatoes
Different varieties of sweet potatoes offer distinct flavors and textures. You can choose between purple, white, or yellow-fleshed sweet potatoes, depending on your preference. Additionally, you may opt for mealy or waxy sweet potatoes.
When purchasing, select sweet potatoes of moderate size that feel heavy for their weight. Look for intact, unbruised potatoes with undamaged skin free from black spots or signs of mold. Fresh sweet potatoes have a natural, pleasant aroma. Avoid those with a pungent or spicy smell, indicating spoilage or bacterial infection (commonly known as “ha” or “sung” in some regions).
Sweet potatoes can be cooked immediately after purchase, but for a sweeter treat, consider storing them in a cool, ventilated area for 5-7 days. During this period, the potatoes will lose some moisture, resulting in a higher sugar concentration and a more intense sweetness.

Tips for Boiling Sweet Potatoes Quickly and Perfectly
Before cooking, rinse the sweet potatoes thoroughly under running water to remove any dirt or debris. One essential trick to preserving the flavor and texture of boiled sweet potatoes is to keep the skin intact during boiling. The skin helps retain nutrients and prevents the potatoes from becoming watery and bland.
Simply trim both ends of the sweet potato, as these areas tend to be fibrous and less flavorful. Additionally, removing the ends helps the potatoes cook more quickly and evenly.
Another trick to expedite the cooking process and ensure even cooking is to pierce the sweet potatoes multiple times with a sharp skewer or fork. Alternatively, you can use a knife to make a few shallow cuts on the surface of the potatoes. This step allows steam to escape, reducing cooking time and promoting even cooking.
- Boiling Sweet Potatoes in Water
Fill a pot with clean water and bring it to a rolling boil over high heat. Only then should you add the sweet potatoes. Boiling them in already hot water helps retain their natural sweetness.
Maintain a boiling temperature for about 10 minutes. Then, reduce the heat to low and continue cooking for another 5-10 minutes, depending on the size of the potatoes.
Once the potatoes are tender, drain the water and return the pot to the stove for a few minutes to allow the potatoes to dry and concentrate their flavor. This step is especially important for waxy sweet potatoes, as it helps draw out and caramelize their natural sugars, resulting in a more appealing presentation.

- Boiling Sweet Potatoes in a Rice Cooker
You can also boil sweet potatoes in a rice cooker. Simply add enough water to reach halfway up the potatoes, press the cook button, and wait for them to cook. To check if they’re done, use chopsticks to pierce a potato. If they slide in easily, the potatoes are ready. If not, press the cook button again and add more water if necessary.
- Microwave Cooking
For microwave cooking, wrap the sweet potatoes in paper towels to retain moisture. Alternatively, use microwave-safe plastic wrap, ensuring it’s designed for high-temperature use. Place the wrapped potatoes on a ceramic plate and microwave for approximately 5 minutes for a standard-sized potato. Larger potatoes may require up to 8-9 minutes.
These tips and tricks will help you boil sweet potatoes efficiently, ensuring a delicious and perfectly cooked dish every time.
