Start by preheating your oven to 400°F (200°C). Slice the pears thinly and toss them with olive oil, salt, and pepper. Spread them evenly on a lined baking sheet so they roast properly without steaming.
Place the pears in the oven and roast for about 15 minutes. You want them soft and slightly caramelized, not mushy. This step enhances their natural sweetness and adds depth to the final dish.
While the pears are roasting, place your flatbread on a baking tray. If you like a crispier base, lightly brush it with olive oil. This helps create a golden, crunchy texture.
Once the pears are ready, arrange them evenly over the flatbread. Sprinkle crumbled feta and optional mozzarella on top. Add fresh thyme for an aromatic touch that complements both sweet and savory elements.
Transfer the assembled flatbread to the oven and bake for 8–10 minutes. The cheese should soften and slightly melt while the edges of the crust become crisp and golden.
Remove the flatbread from the oven and drizzle honey generously over the top. Add fresh arugula if using, for a burst of color and peppery flavor. Let it cool slightly before slicing.
