    slow roasted tomatoes in small jars

    Slow Roasted Tomatoes are the easy way to enjoy peak summer tomatoes all winter long, just roast and freeze. No canning required. 

    Maybe, like me, you've seen something like this at your farmer's market lately: crates of plump and glistening red, perfectly ripe, tomatoes. And let's say that, like me, you don't want to take the time to can them. But to turn and walk away? Just leave them there? It's out of the question. Because soon, the farmer's market will close for the season and tomatoes will be of the too firm, phony red, flavorless, grocery store variety.

    If this resonates with you, then I have very good news. 

    You can slow roast pounds of these beauties - at least 10 pounds at once - pack them in jars, stack them in the freezer, and resurrect the flavor of summer whenever you like, all winter long.

    Ingredients You Need to Make Slow Roasted Tomatoes:

    • Tomatoes: ideally small plum tomatoes
    • Olive Oil: extra-virgin olive oil
    • Fresh Thyme: or chopped fresh rosemary
    • Fine Sea Salt

    I can't take credit for this idea - I read about it here. And it was David Lebovitz' recipe note that saved me from a day of canning:

    The tomatoes will keep for about five days in the refrigerator. They can also be frozen for up to six months.

    FAQ

    Why roast tomatoes slowly?

    When you slow roast tomatoes, their flavor deepens and intensifies. Imagine the flavor of an oil packed, sun-dried tomato in the form of a tender, cooked tomato.

    How long can I keep slow roasted tomatoes?

    Refrigerate for up to 5 days or freeze for up to 6 months.

    How long do you roast a tomato?

    Tomatoes are best roasted low and slow in an oven preheated to 225°F for 4 hours (rotating pans between racks every 45 minutes).

    Does roasting tomatoes make them sweeter?

    Yes! Tomatoes develop a deep sweetness as they slowly roast.

    Tomatoes Ready to Roast

    Bake in a 225°F oven 4 hours, rotating the pans among the racks every 45 minutes. Remove from oven to cool.

    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
    • ½ 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.
