Preheat oven to 400 degrees. Line a large baking sheet with a silicone mat (preferred) or foil.
Dice potatoes into 1/2-inch cubes. You can peel them if you wish, but it is not necessary.
Place potatoes in a large bowl and toss with olive oil. Add seasonings and toss to coat. Seasonings can be adjusted to taste.
Arrange potatoes in a single layer on lined baking sheet and bake at 400 degrees for 20 minutes or until cooked through.
Carefully stir the potatoes and then broil for 2 to 4 minutes until golden and crispy. Stir and broil once more.
Serve sprinkled with chopped parsley or chives if desired.
