- 20-25 minutes for thick sweet potatoes
Medium Sweet Potatoes (2-3 inches in diameter)
- 15-18 minutes for thin sweet potatoes
- 20-25 minutes for medium-thick sweet potatoes
- 30-35 minutes for thick sweet potatoes
Large Sweet Potatoes (3-4 inches in diameter)
- 20-25 minutes for thin sweet potatoes
- 30-35 minutes for medium-thick sweet potatoes
- 40-45 minutes for thick sweet potatoes
How to Boil Sweet Potatoes to Perfection
Now that we’ve discussed the cooking time guidelines, let’s provide a step-by-step guide on how to boil sweet potatoes to perfection.
Step 1: Choose the Right Sweet Potatoes
Choose sweet potatoes that are firm and free of bruises or soft spots. Wash the sweet potatoes thoroughly and pat them dry with a paper towel.
Step 2: Peel and Chop (Optional)
If you prefer to peel your sweet potatoes, use a vegetable peeler to remove the skin. You can also chop the sweet potatoes into smaller pieces if you prefer.
Step 3: Place in a Pot
Place the sweet potatoes in a large pot and add enough cold water to cover them. Make sure the water level is at least 2-3 inches above the sweet potatoes.
Step 4: Bring to a Boil
Place the pot over high heat and bring the water to a boil. Once the water is boiling, reduce the heat to medium-low and simmer.
Step 5: Cook to Perfection
Cook the sweet potatoes for the recommended time based on their size and shape. Check for doneness by inserting a fork or knife into the sweet potato. If it slides in easily, the sweet potato is cooked.
Step 6: Drain and Serve
Once the sweet potatoes are cooked, drain the water and serve them hot. You can add butter, salt, or other seasonings to taste.
Tips and Variations
Here are some tips and variations to enhance your boiled sweet potato experience:
Add Aromatics
Add aromatics like garlic, onion, or bay leaves to the water for added flavor.

How long does it take to boil sweet potatoes until they are soft?
Boiling sweet potatoes can take anywhere from 10 to 30 minutes, depending on their size and desired level of softness. Generally, smaller sweet potatoes will be tender in about 10-15 minutes, while larger ones may take up to 25-30 minutes. It’s essential to check on them periodically to avoid overcooking, which can make them mushy and unappetizing.
To check for doneness, insert a fork or knife into the sweet potato. If it slides in easily, it’s cooked through. If not, continue boiling and checking until it reaches your desired level of softness. Keep in mind that boiling time may also vary depending on the altitude and personal preference for texture.
What factors affect the boiling time of sweet potatoes?
Several factors can influence the boiling time of sweet potatoes, including their size, shape, and variety. Larger sweet potatoes, for instance, take longer to cook than smaller ones. The shape of the sweet potato can also impact cooking time, with rounder sweet potatoes cooking more evenly than longer, thinner ones. Additionally, different varieties of sweet potatoes may have varying densities, which can affect their cooking time.
Other factors, such as the altitude, water temperature, and desired level of softness, can also impact boiling time. At higher elevations, water boils at a lower temperature, which can increase cooking time. Similarly, if you prefer your sweet potatoes very soft, you may need to boil them for a longer period than if you like them slightly firmer.
Can I boil sweet potatoes with their skin on?
Yes, you can boil sweet potatoes with their skin on. In fact, leaving the skin on can help retain more nutrients and flavor. Simply scrub the sweet potatoes clean and place them in a pot of boiling water. The skin will help protect the flesh from becoming too soft or mushy.
However, if you plan to eat the sweet potatoes as is, you may want to peel them after boiling. The skin can be a bit tough and fibrous, which may not be appealing to everyone. On the other hand, if you’re using the sweet potatoes in a recipe, such as mashed sweet potatoes or sweet potato soup, you can leave the skin on and blend it in for added nutrition and texture.
How do I prevent sweet potatoes from becoming too soft or mushy?
To prevent sweet potatoes from becoming too soft or mushy, it’s essential to monitor their cooking time closely. Check on them every 5-10 minutes to avoid overcooking. You can also use a timer to ensure you don’t forget about them.
Another way to prevent overcooking is to use a steamer basket instead of boiling the sweet potatoes directly in water. Steaming helps retain the sweet potatoes’ natural texture and flavor, and it’s easier to check on them without having to drain the water.
Can I boil sweet potatoes ahead of time and refrigerate or freeze them?
Yes, you can boil sweet potatoes ahead of time and refrigerate or freeze them for later use. In fact, boiling and cooling sweet potatoes can help make them easier to digest. Once cooled, you can refrigerate or freeze them for up to 3-5 days.
When refrigerating or freezing boiled sweet potatoes, make sure to store them in an airtight container to prevent moisture and other flavors from affecting their texture and taste. You can also mash or puree them before refrigerating or freezing for easier use in recipes later on.
Are there any health benefits to boiling sweet potatoes?
Boiling sweet potatoes can help retain some of their natural nutrients, especially water-soluble vitamins like vitamin C and B vitamins. However, boiling can also lead to a loss of some nutrients, especially if the water is not used in the recipe or discarded.
To maximize the health benefits of boiled sweet potatoes, use the cooking water in your recipe or save it as a nutritious broth. You can also add other nutrient-dense ingredients to your boiled sweet potatoes, such as herbs, spices, or healthy oils, to enhance their nutritional value.
Can I boil sweet potatoes in a microwave or Instant Pot?
Yes, you can boil sweet potatoes in a microwave or Instant Pot, but the cooking time and method may vary. Microwaving sweet potatoes can take anywhere from 3-6 minutes, depending on their size and desired level of softness. Simply wash and poke some holes in the sweet potatoes, then cook on high for 3-6 minutes, checking on them every minute until they’re tender.
Cooking sweet potatoes in an Instant Pot can take around 5-10 minutes, depending on the size and desired level of softness. Simply add the sweet potatoes to the Instant Pot with some water, close the lid, and cook on high pressure for 5-10 minutes. Let the pressure release naturally before opening the lid and checking on the sweet potatoes.
