Weekend Project: Slow-Roasted Tomatoes

Cook, Weekend Project

If you’ve never tried slow-roasting tomatoes, now is your perfect opportunity. Summer’s ripe heirlooms and Early Girls are at their sweetest, and while they are flawless eaten fresh with a sprinkle of sea salt and olive oil, roasting adds an entirely new dimension of flavor.


Roasting tomatoes concentrates their sweetness, caramelizing the natural sugars and lending a deep richness to the end result. Prep time is minimal but the tomatoes take a bit of time in the oven, so plan to roast them when you have a few hours of down time at home. You’ll be rewarded with a prized ingredient for your next dish — or, if you’re like us, a snack that’s hard to beat just as is.


Slow-Roasted Tomatoes


8 to 10 plum or 2 cups cherry tomatoes, halved lengthwise

About 1/4 cup extra-virgin olive oil

About 1 tsp. sugar

2 cloves garlic, thinly sliced

Sea salt and ground pepper


Preheat oven to 300 degrees F. Lightly oil a rimmed baking sheet. Arrange tomatoes, cut side up, on prepared baking sheet. Drizzle with olive oil and sprinkle evenly with sugar, garlic and generous amounts of salt and pepper. Roast tomatoes until deep red and wrinkled, 2 to 2 1/2 hours for medium or plum tomatoes and 1 hour for cherry tomatoes.


Remove from oven and let cool on baking sheet. Serve warm or at room temperature. Serves 4 to 6.


If you can resist the roasted tomatoes right out of the oven, try them in one of these versatile dishes:

    I’ve tried this year after year and honestly I think it makes them really bitter, because there is such small amount of sweet tomato “meat” versus surface area of skin. Maybe that bit of sugar will help.
