Preheat your oven to 425°F (220°C).
Wash the russet potatoes thoroughly under cold water to remove dirt.
Pat the potatoes dry with a towel.
Prick each potato several times with a fork to allow steam to escape.
Rub each potato with olive oil and sprinkle with sea salt.
Place the potatoes directly on the oven rack or on a baking sheet.
Bake for 45-60 minutes, until the skin is crispy and a fork easily pierces the flesh.
Remove the potatoes from the oven and let them cool for a few minutes.
Cut a slit down the center of each potato and gently squeeze the ends to fluff the insides.
Add your desired toppings and serve immediately.
