Preheat your oven to 425°F (220°C).

Wash and peel the potatoes, then cut them into domino shapes (rectangles about an inch thick).

In a large bowl, toss the potato pieces with olive oil, sea salt, oregano, and black pepper until evenly coated.

Spread the seasoned potatoes in a single layer on a parchment-lined baking sheet, ensuring they’re not crowded.

Roast in the preheated oven for 30-35 minutes or until golden brown and crispy, flipping halfway through cooking.

Let cool slightly before serving. Garnish with extra oregano if desired.
