Slow Roasted Tomatoes with Olive Oil and Thyme

We had a bumper crop of thyme in our herb garden this year, so I chose to use it. Rosemary would also be great, or just leave them plain.

Ingredients

  • 10 pounds small plum tomatoes stems removed
  • 1 cup olive oil for drizzling
  • 1/2 cup chopped fresh thyme or chopped fresh rosemary
  • fine sea salt to taste

Instructions

  • Preheat oven to 225°F
  • Arrange 3 oven racks to the top, middle and bottom positions of your oven. Line 3 rimmed baking sheets with parchment paper.
  • Rinse tomatoes and cut them in half crosswise (equator, instead of top to bottom) and arrange, cut side up, on prepared baking sheets.
  • Drizzle tomatoes with olive oil and sprinkle with fresh herbs. Sprinkle with salt to taste (I recommend a light sprinkle as the flavor will intensify).
  • Roast for 3 hours, until tomatoes are soft and shriveled. Rotate the sheets among the racks every 45 minutes or so, to cook the tomatoes evenly.
  • Cool tomatoes until they're comfortable to handle. Then fill your clean, lidded jars almost to the top and freeze.

Notes

10 pounds of tomatoes will yield about 10 cups. I filled 12 4-ounce jars and 2 16-ounce jars.
