Preheat oven to 400 degrees. In a large shallow baking dish, combine butter, lemon juice, sugar and vanilla bean (seeds and pod). Add peaches and turn to coat with butter mixture. Arrange peaches cut side down in a single layer.
Roast peaches until tender and cooking liquid is syrupy, 20-25 minutes. Brush with cooking liquid halfway.
Serve peaches with a scoop of ice cream and raspberries and drizzle with cooking liquid.
Notes
* 1 teaspoon vanilla extract can be substituted for the vanilla bean
