Preheat your oven to 400℉. Line a baking sheet with parchment paper.
Using a spoon, scoop out the flesh of each zucchini half. (Reserve the flesh for an omelette or a quick veggie sauté at a later date).
Brush the scooped side of each zucchini with olive oil. In this order, season with salt and pepper to taste, then add the parmesan, garlic powder, onion powder, oregano, and shredded cheese evenly to each piece. Sprinkle the tops of each with paprika and chili pepper flakes. Bake for 20 minutes or until the zucchini is just fork tender.
Notes
*You can also add a sprinkle of breadcrumbs to each (after the salt and pepper step) to keep them dry as possible.
