First things first, get your oven preheating to 375°F (190°C). This ensures it's nice and hot when your peaches are ready to go in.
Grab those beautiful peaches. Carefully cut each one in half, following the seam all the way around. Give the halves a gentle twist, and they should separate easily. Then, use a spoon or paring knife to carefully scoop out the pit.
Arrange the pitted peach halves in a baking dish that's just large enough to hold them snugly, cut-side facing up.
Now, let's make that irresistible topping! In a small microwave-safe bowl or a tiny saucepan, melt the butter. Once melted, stir in the brown sugar, cinnamon, nutmeg, cloves, and that crucial pinch of salt until it's all combined into a thick, fragrant mixture.
Spoon this glorious butter-sugar mixture evenly into the little hollow where the pit used to be in each peach half. Don't be shy, get a good amount in there!
Pop the baking dish into your preheated oven. Bake for 20-30 minutes. The exact time will depend on how ripe your peaches are. You're looking for them to be tender when you gently pierce them with a fork, and the topping should be bubbly and smell amazing.
Carefully remove the dish from the oven (it's hot!). Let the peaches cool just slightly for a few minutes before serving.
