Baking sweet potatoes in the oven is easy and tasty. Sweet potatoes are healthy and sweet. You can eat them for lunch, dinner, or a snack. This guide will show you how to bake sweet potatoes step by step.

What You Need
- Sweet potatoes (choose medium size for even cooking)
- Olive oil or any cooking oil (optional)
- Salt (optional)
- Fork or knife
- Baking tray
- Aluminum foil (optional)
- Oven
Choosing the Right Sweet Potato
Pick sweet potatoes that feel firm and heavy. Avoid potatoes with soft spots or wrinkles. Medium size sweet potatoes cook better than very big or very small ones. The skin should be smooth and clean.
Step 1: Preheat the Oven
Start by heating your oven. Set it to 400 degrees Fahrenheit (about 200 degrees Celsius). Wait until the oven is fully hot before you put the sweet potatoes in.

Step 2: Wash the Sweet Potatoes
Rinse the sweet potatoes under cold water. Use your hands or a brush to clean dirt from the skin. Dry them with a clean towel. This helps make the skin nice when baked.
Step 3: Poke Holes in the Sweet Potatoes
Use a fork or knife to poke holes all over the sweet potatoes. This lets steam escape while baking. Without holes, the sweet potato can burst inside the oven.
Step 4: (Optional) Add Oil and Salt
You can rub the sweet potato skin with a little oil. This makes the skin crispy. Sprinkle some salt if you like. This step is not needed, but it adds flavor.
Step 5: Place Sweet Potatoes on Baking Tray
Put the sweet potatoes on a baking tray. You can use aluminum foil on the tray to catch drips. Make sure the potatoes do not touch each other. This helps them cook evenly.
Step 6: Bake the Sweet Potatoes
Put the tray with sweet potatoes in the oven. Bake for 45 to 60 minutes. The time depends on the size of the potato. Medium sweet potatoes usually take 50 minutes.
Check the potatoes after 45 minutes. Use a fork to poke the thickest part. If the fork goes in easily, the potato is done. If it feels hard, bake longer.
Step 7: Let the Sweet Potatoes Cool
Take the sweet potatoes out of the oven carefully. They will be very hot. Let them cool for about 5 to 10 minutes. This makes them easier and safer to handle.
Step 8: Serve Your Sweet Potatoes
Cut the sweet potato open with a knife. The inside should be soft and orange. You can add butter, salt, or cinnamon. Or eat them plain for natural sweetness.
