Preheat the oven to 400ºF/204ºC. Line a sheet pan with parchment paper and set aside. Meanwhile, slice the sweet potatoes legthwise and coat them in oil and then season with salt, pepper, Italian seasoning and garlic powder. Place them cut side down onto the parchment lined sheet pan.
Place the sweet potatoes in the oven and let them roast for 20 minutes.
Shred the mozzarella and parmesan and set them aside. Once the sweet potatoes are ready, mash then lightly with a fork to break apart the potato and make it easier to scoop. Divide the parmesan and mozzarella cheeses equally between the sweet potatoes and put them back in the oven to broil for 3-4 minutes or until the cheese has melted and browned slightly.
Garnish with red pepper flakes, basil or parsley and enjoy immediately.
Notes
Get blocks of cheese and shred them at home for the best results.
