Preheat the oven to 350 degrees F (180 degrees C).
In a measuring cup mix Olive Oil (1/4 cup), Garlic Powder (1 teaspoon), Onion Powder (1 teaspoon), and Dried Mixed Herbs (2 teaspoon). Season with Salt and Pepper (to taste) and mix well together.
Chop the Potato (2 pound) into little pieces and partially cook them. You can boil them on the stove for 5 to 10 minutes until they are still firm and not cooked through yet.
In a roasting pan, line with non-stick baking paper and put the partially cooked potatoes on the pan. Drizzle the mixed seasoning over them and mix well with a wooden spoon.
Put it into the preheated oven and bake for about 1 hour or until they are crispy on the outside and soft on the inside.
