Wash and scrub the potatoes thoroughly. Place them in a large pot and cover with water. Add salt and bring to a boil.

Cook the potatoes until fork-tender, about 15-20 minutes. Drain and let cool slightly.

Preheat the oven to 450°F (230°C). Line a baking sheet with parchment paper.

Place the cooked potatoes on the baking sheet. Use a fork or potato masher to gently smash each potato until flattened but still intact.

Drizzle olive oil over the smashed potatoes and sprinkle with garlic powder, onion powder, black pepper, and additional salt to taste.

Bake in the preheated oven for 20-25 minutes, or until the edges are golden brown and crispy.

Remove from the oven and garnish with chopped parsley before serving.
