Preparing Potatoes for Oven with Foil
Proper preparation ensures even cooking and optimal flavor.
Cleaning and Scrubbing
- Rinse potatoes thoroughly under cold water.
- Use a vegetable brush to remove dirt and debris.
- Pat dry with a clean towel.
Pricking or Poking
- Use a fork to poke several holes in the potato skin.
- This allows steam to escape and prevents bursting.
Optional Seasoning
- Lightly brush the potato skin with olive oil or melted butter.
- Sprinkle with salt, pepper, garlic powder, or herbs for added flavor.
- For stuffed or flavored baked potatoes, seasonings can be added before wrapping.
Wrapping in Foil
- Tear off a large sheet of aluminum foil, enough to fully encase the potato.
- Place the potato in the center.
- Fold the foil around the potato, sealing tightly to prevent steam from escaping.
- For a crisper skin, you can poke a small vent in the foil or leave the top slightly open.
