Preheat the oven to 450°F and line a baking sheet with parchment paper.
In a large pot, bring 4 cups of water to a boil. Once boiling, stir in 1 teaspoon salt and ½ teaspoon baking soda.
Carefully add the chopped potatoes to the boiling water. Boil uncovered for 8–10 minutes, or until the edges are just starting to soften.
Drain the potatoes using a colander, then let them sit for about 10 minutes to steam off excess moisture. This helps achieve a crispier texture.
Once mostly dry, transfer the potatoes to a large bowl. Add 1 tablespoon oil and a pinch of salt. And any herbs and spices you want to add. Gently toss to coat without breaking the potatoes.
Arrange the potatoes in a single layer on the prepared baking sheet, leaving space between each piece.
Roast for 40 minutes, flipping once or twice during cooking, until golden and crispy on all sides.
For an extra-crispy finish, broil for 1–2 minutes, keeping a close eye to prevent burning.
