Step-by-Step Guide to Baking a Jacket Potato in the Oven

Step 1: Preheat the Oven

Preheat your oven to your chosen temperature (200°C is ideal for crispy skin).

Step 2: Choose the Right Potato

Opt for floury varieties like Maris Piper, King Edward, or Russet for the best fluffy texture.

Step 3: Wash and Dry

Wash the potatoes thoroughly under running water and scrub the skin clean. Pat them completely dry with a clean towel.

Step 4: Pierce the Skin

Use a fork to poke several holes around the potato to allow steam to escape during cooking.

Step 5: Season and Oil (Optional)

Rub the potato with olive oil or butter for a crispier skin.
Sprinkle with salt for added flavor.

Step 6: Place on a Baking Tray

Arrange the potatoes directly on the oven rack or a baking tray lined with parchment paper.

Step 7: Bake

Place the potatoes in the oven and bake for the recommended time based on their size and temperature.

Step 8: Check for Doneness

Insert a fork or skewer into the thickest part of the potato. If it slides in easily, the potato is done.

Step 9: Serve and Enjoy

Remove the potato from the oven, slice it open, fluff the interior with a fork, and add your favorite toppings.

Tips for Perfect Jacket Potatoes

Choose Similar Sizes: If baking multiple potatoes, select ones of similar size for even cooking.
Don’t Skip Piercing: Piercing prevents the potato from bursting during baking.
Crispier Skin: Rub the skin with oil and salt for a crispy, golden crust.
Avoid Wrapping in Foil: Baking without foil ensures crispy skin, while foil traps steam and softens the texture.
Reheat Leftovers: Reheat baked potatoes in the oven at 180°C (350°F) for 15-20 minutes for a freshly baked texture.

Delicious Topping Ideas for Jacket Potatoes

Classic: Butter, sour cream, and chives
Cheesy: Grated cheddar, mozzarella, or Parmesan
Healthy: Greek yogurt, avocado, or steamed broccoli
Hearty: Baked beans, chili con carne, or pulled pork
Vegan: Hummus, roasted chickpeas, or sautéed mushrooms
