Sweet potatoes are a delicious and nutritious addition to any meal, but cooking them can be a bit tricky. One of the most common questions people have when it comes to cooking sweet potatoes is how long to cook them. The answer, however, is not as simple as it seems. The cooking time for sweet potatoes depends on several factors, including the method of cooking, the size and shape of the sweet potatoes, and the desired level of doneness.
Understanding Sweet Potato Cooking Methods
Before we dive into the cooking times, it’s essential to understand the different methods of cooking sweet potatoes. Each method has its own unique characteristics, and the cooking time will vary accordingly.
Baking Sweet Potatoes
Baking sweet potatoes is a popular method, and it’s relatively easy to do. To bake sweet potatoes, preheat your oven to 400°F (200°C). Scrub the sweet potatoes clean and poke some holes in them with a fork to allow steam to escape. Rub the sweet potatoes with a little bit of oil and place them on a baking sheet lined with parchment paper. The cooking time will depend on the size of the sweet potatoes, but here are some general guidelines:
- Small sweet potatoes (100g): 45-60 minutes
- Medium sweet potatoes (150g): 60-75 minutes
- Large sweet potatoes (200g): 75-90 minutes
Boiling Sweet Potatoes
Boiling sweet potatoes is another common method, and it’s a great way to cook them quickly. To boil sweet potatoes, place them in a large pot of salted water and bring to a boil. Reduce the heat to medium-low and simmer for 10-15 minutes, or until the sweet potatoes are tender when pierced with a fork.
Steaming Sweet Potatoes
Steaming sweet potatoes is a healthy and flavorful way to cook them. To steam sweet potatoes, place them in a steamer basket over boiling water. Cover the pot with a lid and steam for 10-15 minutes, or until the sweet potatoes are tender.
Roasting Sweet Potatoes
Roasting sweet potatoes brings out their natural sweetness and adds a nice caramelized flavor. To roast sweet potatoes, preheat your oven to 425°F (220°C). Cut the sweet potatoes into wedges or cubes and toss with oil, salt, and your choice of spices. Spread the sweet potatoes out in a single layer on a baking sheet and roast for 20-30 minutes, or until they’re tender and caramelized.
Grilling Sweet Potatoes
Grilling sweet potatoes adds a smoky flavor and a nice char. To grill sweet potatoes, preheat your grill to medium-high heat. Cut the sweet potatoes into slices or wedges and brush with oil. Grill the sweet potatoes for 5-7 minutes per side, or until they’re tender and slightly charred.
Microwaving Sweet Potatoes
Microwaving sweet potatoes is a quick and easy way to cook them, but it’s essential to be careful not to overcook them.

The knife test is another way to check for doneness. Insert a knife into the sweet potato, and if it slides in easily, it’s cooked.
The Squeeze Test
The squeeze test is a great way to check if your sweet potatoes are cooked. Squeeze the sweet potato gently, and if it yields to pressure, it’s cooked.
Common Mistakes to Avoid
When cooking sweet potatoes, there are several common mistakes to avoid. Here are some of the most common mistakes:
Overcooking
Overcooking is one of the most common mistakes when cooking sweet potatoes. Overcooking can make the sweet potatoes dry and unappetizing.
Undercooking
Undercooking is another common mistake. Undercooked sweet potatoes can be hard and unpalatable.
Not Poking Holes
Not poking holes in the sweet potatoes can cause them to explode in the oven or microwave.
