Preheat your oven to 400F and line a baking sheet with parchment.
Place your sweet potatoes in a bowl and add the olive oil, garlic powder, spice mix and some salt + pepper. Mix until sweet potatoes are well coated.
Sprinkle parmesan cheese onto your baking sheet and spread so that it's evenly coated.
Place sweet potatoes cut-side down on top of the parmesan.
Bake for 30-40 minutes until sweet potatoes are tender and the bottom layer of cheese is crispy and deeply browned.
Remove, let cool + serve topped with herbs and oil!
