How to Eat Sweet Potato

Sweet potatoes can be baked, roasted, mashed, fried, or even eaten raw. Baking whole at 400°F for 45-60 minutes caramelizes their natural sugars. Cube and roast with olive oil and spices for a delicious side. Use in soups, curries, and casseroles. Sweet potato fries are a popular healthier alternative to regular fries. The skin is edible and nutritious.

Selection and Storage

Choose firm sweet potatoes without cracks, soft spots, or sprouts. Store in a cool, dark, well-ventilated place (not the refrigerator) for up to 3-4 weeks. Once cut, wrap and refrigerate for up to a week. Cooked sweet potatoes can be refrigerated for 3-5 days or frozen for up to 12 months.

Dietary Considerations

Sweet potatoes are naturally gluten-free, vegan, and suitable for paleo diets. They're an excellent carbohydrate source for athletes. Those on very low-carb or keto diets may need to limit portions. The skin adds fiber, so eating it when possible is recommended.
