What is a Sweet Potato?

Sweet potato (Ipomoea batatas) is a starchy root vegetable native to Central and South America. Unlike regular potatoes, sweet potatoes are naturally sweet and come in varieties ranging from orange and yellow to purple and white.

Sweet potatoes are widely used in American cuisine due to their versatility and robust nutritional profile. Whether roasted, mashed, baked, or incorporated into pies and casseroles, sweet potatoes add texture, flavor, and color to countless dishes.

Pro Tip: Look for sweet potatoes that are firm, smooth, and free from cracks or soft spots. Smaller roots tend to cook more evenly and have a sweeter flavor.

Potassium: Helps maintain healthy blood pressure.
Manganese: Supports metabolism and bone health.
Complex Carbohydrates: Provide steady energy without spiking blood sugar.

Pro Tip: The orange-fleshed varieties contain the highest levels of beta-carotene, while purple sweet potatoes are rich in antioxidants that support heart and brain health.

How to Prepare Sweet Potatoes

Sweet potatoes are extremely versatile and can be prepared in numerous ways:

Baked: Bake whole or cubed sweet potatoes in the oven until soft. Perfect for side dishes or stuffed potato recipes.
Mashed: Boil or steam, then mash with butter, cream, or coconut milk for a creamy, flavorful side.
Roasted: Toss cubed sweet potatoes with olive oil, salt, and spices for a caramelized, golden side dish.
Fried: Make sweet potato fries or chips for a crispy snack.
Soups and Stews: Puree cooked sweet potatoes to create creamy soups or hearty stews.

Proper storage keeps sweet potatoes fresh and flavorful:

Store in a cool, dry, and dark place—not in the refrigerator, as cold temperatures can alter their flavor.

Use within 3–5 weeks for best texture and taste.
Cooked sweet potatoes can be stored in an airtight container in the refrigerator for 3–5 days or frozen for up to 3 months.
