Heat the oven: Preheat to 375°F (190°C).
Lightly butter a small baking dish or line with parchment.
Prep the pears: Halve them lengthwise and scoop out the core with a spoon or melon baller. Leave stems on if you like the look.
Add a bright note: Brush cut sides with a little lemon juice to keep the color fresh.
Flavor boost: Stir honey with cinnamon, vanilla, and a tiny pinch of salt. Warm 10 seconds if needed to thin.
Assemble: Nestle pears cut side up in the dish.
Dot with butter or drizzle with olive oil. Spoon the honey mixture over the pears, letting some pool in the centers.
Bake: Cook for 25–35 minutes, basting once or twice with the pan juices. They’re done when a knife slips in easily and edges look lightly caramelized.
Finish: Scatter chopped nuts over the top and bake 5 more minutes to toast them slightly.
Serve: Spoon the syrupy juices over the pears.
Add yogurt, mascarpone, or ice cream. Serve warm.
