Selecting and Storing Sweet Potatoes
Choosing the right sweet potatoes starts at the grocery store or farmers market. Look for potatoes that feel firm when you gently squeeze them. Avoid any with soft spots, bruises, or wrinkled skin, as these indicate decay or age. Sweet potatoes come in different varieties. The most common in U.S. stores are the orange-fleshed varieties, which have a sweeter taste and softer texture. You may also find white-fleshed or purple-fleshed varieties, each with slightly different flavors and cooking properties. Orange varieties tend to become very soft when cooked, while white varieties maintain more firmness.

Size matters for cooking time. Smaller to medium sweet potatoes (about 5 to 8 inches long) cook more evenly than very large ones. If you buy large potatoes, they may have hard centers even after the outside is done cooking. A medium sweet potato typically weighs between 5 and 8 ounces. When selecting multiple potatoes for the same meal, try to choose similar sizes so they cook at the same rate.
Storage conditions affect how long your sweet potatoes stay fresh. Unlike regular potatoes, sweet potatoes do not store well in the refrigerator. Instead, keep them in a cool, dark place like a pantry or basement where temperatures stay between 55 and 75 degrees Fahrenheit. Properly stored sweet potatoes can last 2 to 3 weeks, sometimes longer. High humidity or cold temperatures can cause them to rot or develop an unpleasant flavor. Keep them away from direct sunlight, which can cause the skin to turn green or sprout.
Never store sweet potatoes in a plastic bag, as trapped moisture promotes rot. Instead, place them in a basket or on a shelf where air can circulate around them. If one potato begins to decay, remove it immediately to prevent the rot from spreading to others. Check your stored potatoes every few days, especially during warm months when they deteriorate faster.
Practical Takeaway: Purchase firm, medium-sized sweet potatoes and store them in a cool, dark place with good air circulation. Check them regularly and remove any that show signs of spoilage.
Washing and Preparing the Skin
Before cooking, wash your sweet potatoes thoroughly under running water. Use a vegetable brush or clean scrubbing cloth to remove dirt, sand, and debris from the skin. This step is important whether you plan to peel before or after cooking. Even if you plan to remove the skin later, washing prevents dirt from transferring to the flesh when you cut the potato.

The skin of a sweet potato is edible and contains fiber and nutrients. Many cooking methods can be used with the skin on, including baking, boiling, and steaming. The skin becomes softer during cooking and many people find it pleasant to eat. If you prefer to remove the skin before cooking, you can do so by peeling with a vegetable peeler, but this takes more effort on a raw sweet potato than on a cooked one. Raw sweet potato skin is quite tough and resistant to peeling.
Removing the skin after cooking is often easier. When a sweet potato is soft from cooking, the skin slips off much more readily. Allow the cooked potato to cool slightly until you can handle it, then gently peel away the skin with a knife or your fingers. This method wastes less of the potato and is less labor-intensive. You can cook with the skin on and then remove it, or leave it on entirely depending on your recipe and preference.
If you need to peel raw sweet potatoes for recipes like stews or stir-fries, use a sharp vegetable peeler or knife. Cut the potato in half lengthwise first to create a flat surface, which makes peeling safer and easier. Some people find it helpful to briefly soak raw sweet potatoes in warm water for 5 to 10 minutes, which can slightly soften the skin and make peeling less difficult. Work carefully, as the potato can be slippery when wet.
Practical Takeaway: Always wash sweet potatoes before cooking. Decide whether to peel before or after cooking based on your recipe, knowing that peeling after cooking is usually easier.
Cutting Techniques for Different Cooking Methods
How you cut sweet potatoes affects cooking time and how they turn out. For baking whole, you do not need to cut them at all. Simply poke several holes with a fork to allow steam to escape. For faster cooking, you can cut potatoes in half lengthwise before baking. This reduces cooking time by roughly half and makes them easier to portion and serve.

For boiling and steaming, cut potatoes into uniform pieces. Cubes about 1 inch on each side cook in roughly 8 to 12 minutes when boiling, depending on exact size. Smaller pieces cook faster but may become mushier. Larger chunks take longer but maintain better texture. If you are boiling potatoes for mashing, aim for 1 to 1.5 inch cubes. For soups and stews, cut them into smaller pieces, around 0.5 to 0.75 inches, so they blend well with other ingredients or become tender enough to cut with a spoon.
Roasting requires different cuts than boiling. Cut potatoes into wedges or fries if you want them to get crispy on the outside. For cubed roasted sweet potatoes, cut them into roughly 1-inch pieces. Thinner cuts crisp up faster, while thicker pieces develop a softer interior. Consistent sizing ensures even cooking. For fries, cut potatoes lengthwise into strips about 0.25 to 0.5 inches thick. Thinner fries crisp faster but are more prone to burning, while thicker ones stay softer inside.
When making sweet potato mash or puree, cut potatoes into chunks of 2 to 3 inches. You can peel before or after cooking depending on your preference and the cooking method. If you are using a mandoline slicer or food processor, be very careful with your fingers, as sweet potatoes can be hard and the equipment is sharp. Always use the hand guard provided with these tools.
Practical Takeaway: Cut sweet potatoes into uniform sizes appropriate to your cooking method: large chunks or halves for baking, 1-inch cubes for boiling, and thinner cuts for fries and roasting.
Cooking Methods and Timing
Baking is one of the most straightforward ways to prepare sweet potatoes. Preheat your oven to 400 degrees Fahrenheit. Wash the potato, poke holes all over with a fork, and place it directly on the oven rack with a baking sheet underneath to catch any drips. A medium whole sweet potato takes about 45 to 60 minutes to become completely soft. You can check for doneness by squeezing it gently with an oven mitt or piercing it with a fork. The flesh should feel very soft inside. Halved potatoes cook in about 25 to 35 minutes. Baked sweet potatoes retain their nutrients well and develop a naturally sweet flavor.

Boiling is faster than baking. Cut peeled potatoes into 1 to 1.5 inch cubes and place them in a pot of cold water. Bring the water to a boil over high heat. Once boiling, reduce heat to medium and simmer for 8 to 12 minutes until a fork passes through easily. Do not overcook, or the potatoes will become mushy and waterlogged. Drain immediately after cooking. Boiled sweet potatoes work well for mashing, adding to soups, or mixing into other dishes.
Steaming preserves more nutrients than boiling because the potatoes do not sit in water. Fill a pot with about 2 inches of water and place a steamer basket inside. Bring water to a boil, then add cut sweet potatoes in a single layer. Cover and steam for 12 to 15 minutes for 1-inch cubes, or 15 to 20 minutes for halved potatoes. Check with a fork for tenderness. Steamed potatoes have a firmer texture than boiled ones.
Roasting brings out sweetness and creates crispy edges. Cut potatoes into fries, wedges, or cubes, toss with a small amount of oil, and spread on a b
