Preheat Oven: Preheat your oven to 400°F (200°C).
Prepare Tomatoes: Slice tomatoes and place them on a baking sheet lined with parchment paper. Drizzle with olive oil and season with salt, pepper, garlic powder, basil, and oregano.
Add Cheese: Sprinkle shaved Parmesan evenly over the tomato slices.
Bake: Bake in the preheated oven for 15–20 minutes, until the cheese is melted, golden, and slightly crispy on the edges.
Serve: Remove from oven and let cool slightly. Serve warm as a side dish, appetizer, or topping for pasta.
