Preheat the oven to 400°F (200°C). Spread the frozen fries evenly on a baking sheet. Bake for 15 minutes or until crispy and golden brown. Remove from oven and set aside.
While fries are baking, heat a skillet over medium-high heat. Add olive oil and then the ground beef. Cook, stirring frequently, until beef is browned and cooked through, about 5-7 minutes. Season with salt, pepper, and garlic powder during cooking. Once cooked, transfer beef to a plate and set aside.
