In a medium saucepan, bring the vegetable broth to a boil over medium heat.
Gradually whisk in the cornmeal, stirring continuously to prevent lumps from forming.
Reduce the heat to low, and cook the mixture, stirring frequently, for about 10-15 minutes until it thickens and begins to pull away from the sides of the pan.
Stir in the grated Parmesan cheese, garlic powder, onion powder, salt, and black pepper until well combined.
Pour the polenta into a greased baking dish, spreading it evenly to about 1-inch thickness.
Allow the polenta to cool and set in the refrigerator for at least 1-2 hours, or until firm.
Preheat your oven to 425°F (220°C).
Once set, cut the polenta into fry shapes (approximately 1/2 inch wide).
Arrange the fries on a baking sheet lined with parchment paper, ensuring they are in a single layer.
Drizzle the olive oil over the fries and toss to coat them evenly.
Bake in the preheated oven for 25-30 minutes, flipping halfway through, until they are golden brown and crispy.
Remove from the oven, garnish with chopped parsley, and serve hot.
