Safety Precautions

Step-by-Step Instructions
- Step 1
Preheat oven
Set the oven to 400°F for a tender inside and lightly caramelized skin.
- Step 2
Scrub and dry
Wash away dirt and dry the skins so they bake instead of steam too much.
- Step 3
Poke holes
Pierce each potato a few times with a fork to vent steam.
- Step 4
Place on sheet
Set potatoes on a lined baking sheet to catch sticky drips.
- Step 5
Bake until tender
Bake until a fork slides easily into the thickest part.
- Step 6
Rest briefly
Let them sit a few minutes so they are easier to handle.
- Step 7
Split and serve
Open with a knife and add butter, cinnamon, yogurt, beans, or savory toppings.
Practical Example
Example: Two medium sweet potatoes bake at 400°F for about 50 minutes, rest for 5 minutes, then get split and topped with butter, salt, and cinnamon.
Common Mistakes
- Skipping the scrub
- Not poking holes
- Baking at too low a temperature
- Removing before fully tender
- Forgetting a lined pan
- Leaving leftovers out too long
Troubleshooting

Return it to the oven and check every 10 minutes.

Bake directly on a pan instead of tightly wrapping in foil.
Sugar leaked onto oven rack
Use a rimmed baking sheet next time.
Potatoes cook unevenly
