Preheat the oven to 425°F, and spray a large baking pan with cooking spray.
In a small bowl, combine the garlic powder, onion powder, and salt.
½ teaspoon garlic powder, ¼ teaspoon onion powder, ¼ teaspoon salt
Cut the potatoes into even-sized strips, about ⅓-inch thick, and place in a large mixing bowl.
2 large russet potatoes
Drizzle the potatoes with oil, toss to combine, sprinkle with half the seasonings, and toss again.
2 teaspoons cooking oil
Place the potatoes in a single layer on the baking sheet. Bake for 20 minutes or until the potatoes are golden brown on the bottom. Flip and cook for an additional 15-20 minutes or until the fries reach the desired doneness.
Take the fries off the pan, and place into another large bowl. While the fries are hot, add more of the seasoning mix and toss to combine. Sprinkle with cracked black pepper if desired.
¼ teaspoon cracked black pepper
Serve immediately!
