  • 4 pounds tomatoes I use romas
  • olive oil for drizzling
  • sea salt/fresh ground pepper
  • finely minced herb(s) (optional)


  • Preheat oven to 225 degrees.
  • Slice tomatoes in half. Arrange on the sheet pan.
  • Drizzle generously with olive oil, rubbing the tomatoes around a little to coat.
  • Season lightly with salt and pepper.
  • Place pan in the oven. After about 3 hours, turn the tomatoes.
  • Cook another 2-3 hours to your preference. We like a lot of caramelization (as shown in the photos).
  • Allow the tomatoes to cool. Sprinkle with herbs if desired. Pack in small zip bags for the freezer or in an airtight jar in the refrigerator for up to a week. 


I almost always use roma tomatoes because I can whip through the prep so fast. The choice is yours. Adjust cooking time as smaller ones cook faster than larger ones.
If using in a salad or bruschetta, bring the tomatoes to room temperature first. If using frozen tomatoes, thaw before adding.
Calories are an approximation only from MyFitnessPal.com, and based on 4 pounds of tomatoes, 1 tablespoon of olive oil (for drizzle), and 16 servings.
