- 4 cups tomatoes (cherry or pear)
Preheat oven to 250°F.
Slice the tomatoes in half and place on a baking sheet cut side up. Place in the oven and cook and 1.5 hours. Rotate the baking sheet, then reduce oven temperature to 200°F and bake for an additional 1.5 to 3.5 hours, checking every 30 minutes for tomatoes that are done and removing those. Small tomatoes will take about 3 hours, while bigger tomatoes will take more like 5 hours.
