Prepare the ingredients: Preheat your oven to 400°F (200°C). Rinse the baby tomatoes under cold water and pat them dry with a clean kitchen towel. Slice the tomatoes in half lengthwise and place them on your tray.
Bake in the oven: Drizzle the olive oil over the halved tomatoes. Sprinkle salt and white pepper. Bake for 20-25 minutes or until softened.
