Why Bake Sweet Potatoes?

Sweet potatoes are packed with nutrients like fiber, vitamin A, and antioxidants. Baking brings out their natural sweetness, making them a fantastic base for savory or sweet toppings. They can stand alone as a side dish or be transformed into fries, mash, or even dessert.

How to Bake a Sweet Potato: Oven Method

The oven is the most reliable way to get a tender, caramelized sweet potato.

Ingredients

1–4 medium sweet potatoes
Olive oil (optional)
Salt (optional)

Directions

Preheat your oven to 400°F (200°C).
Wash and scrub the sweet potatoes thoroughly.
Pat dry and pierce each potato several times with a fork.
Place on a baking sheet lined with parchment paper.
Bake for 45–60 minutes, depending on size, until soft when pierced with a knife.
Slice open and add toppings (butter, cinnamon, sour cream, or herbs).

Pro Tip: Wrapping potatoes in foil will steam them, while leaving them unwrapped gives caramelized skin.
