Instructions
We are focusing on the classic, high-heat method today, which guarantees that soft, caramelized interior. While you might see conflicting advice online, here is the scoop: how long to bake a sweet potato at 350? It takes too long (often over 75-90 minutes). Our optimized 400°F (205°C) temperature gets the job done faster and better.
1. Scrub and Dry
Preheat your oven to 400°F (205°C). Begin by thoroughly washing and scrubbing the sweet potatoes to remove any dirt. Dry them completely with a clean towel.

2. Pierce the Skin
Using a fork, pierce each sweet potato multiple times (about 6-8 times). This step is crucial; it allows steam to escape during baking, preventing the potato from bursting and helping it cook evenly.

3. Oil and Season
Rub the sweet potatoes lightly with olive oil. This helps the skin crisp up beautifully. Sprinkle them generously with sea salt and a little black pepper. Place the seasoned potatoes onto a baking sheet lined with foil or parchment paper for easy cleanup.

4. Bake to Perfection
How long does it take a sweet potato to bake? At 400°F (205°C), medium sweet potatoes usually take between 45 and 60 minutes. You will know they are ready when the skin is slightly wrinkled, and a fork or knife slides into the center with absolutely no resistance.

5. Serve Hot
Once fully baked, remove the potatoes from the oven. Carefully slice them open lengthwise, fluff the orange interior with a fork, and serve immediately with your favorite toppings (a pat of butter and a dash of cinnamon are classic!).
