Savor tomato season a little longer

Editor’s Note: America’s Test Kitchen is a real 2,500 square foot test kitchen located just outside of Boston that is home to more than three dozen full–time cooks and product testers. Our mission is simple: to develop the absolute best recipes for all of your favorite foods. To do this, we test each recipe 30, 40, sometimes as many as 70 times, until we arrive at the combination of ingredients, technique, temperature, cooking time, and equipment that yields the best, most- foolproof recipe. America’s Test Kitchen’s online cooking school is based on nearly 20 years of test kitchen work in our own facility, on the recipes created for Cook’s Illustrated and Cook’s Country magazines, and on our two public television cooking shows.

Story highlights

Great tomatoes have a really short season

Still, too many can show up at once and they're a shame to waste

Extend the season by oven-roasting them and preserving them in olive oil

They can also be frozen, minus the oil, for up to three months

America's Test Kitchen  — 

Fresh summer produce can’t be beat, but if you have a robust garden or a particularly generous CSA arrangement, sometimes the amount of vegetables you’re saddled with can get overwhelming. Fortunately, one of our editors, Scott Kathan, came up with a DIY recipe for using up an abundance of tomatoes.

These oven-roasted tomatoes have countless uses: They make a great addition to antipasti plates, sandwiches, soups, pizzas, and stews, and can be chopped fine and added to mayonnaise as a dip for crudité and crackers. That is, if you can stop yourself from simply eating them plain; they’re what Scott describes as “savory, tender little umami bombs.”

1. Adjust oven rack to upper- and lower-middle positions and heat oven to 425 degrees. Line 2 rimmed baking sheets with parchment paper. Remove and discard tomato cores. Slice tomatoes in half through core and place, cut-side up, on prepared baking sheets. Drizzle 1/2 cup of oil evenly over tomatoes, and season with garlic, herbs de Provence, salt, and pepper. Flip tomatoes cut-side down, transfer to oven, and bake until skins have loosened, about 30 minutes.

    3. Remove tomatoes from oven and pour off any liquid into bowl. Using tongs, carefully flip each tomato half and return to oven until tomatoes are visibly shrunken, dry, and slightly dark around edges, 2 to 2 1/2 hours, pouring off liquid as necessary every 30 minutes.

    4. Transfer baking sheets to wire rack, and allow tomatoes to cool to room temperature. Transfer tomatoes to clean bowl and cover completely with remaining olive oil. Cover bowl with plastic wrap and refrigerate for up to 4 weeks. (If freezing tomatoes, do not cover with oil; transfer to zipper-lock freezer bags and freeze for up to 3 months.) Reserve tomato liquid for another use.
