Instructions:
- Preheat oven to 425°F (220°C). Line a baking sheet with aluminum foil for easy cleanup.
- Scrub the sweet potatoes thoroughly under cold water until completely clean, then dry them entirely.
- Pierce each potato 4-5 times deeply all over with a fork or skewer. This allows steam to escape.
- Rub the exterior of each potato generously with olive oil, then season heavily with coarse sea salt and black pepper.
- Place the seasoned potatoes directly onto the prepared baking sheet (or on a wire rack set on the sheet). Bake for 30 minutes.
- Carefully flip the potatoes and return them to the oven. Continue baking for an additional 15 to 35 minutes, depending on size.
- Test for doneness by gently squeezing (using an oven mitt) or inserting a thin skewer—it should pass through the centre with no resistance.
- Remove from the oven. Let the potatoes rest for 5 minutes before slicing them open lengthwise. Fluff the interior flesh with a fork and serve immediately with desired toppings.
