Drying is a traditional Italian way to preserve an abundance of ripe summer tomatoes so that they can be enjoyed throughout the rest of the year, particularly in the southern Italian regions of Calabria and Puglia. Every year, my ex-boyfriend's mother in Puglia would spreadsheet pans full of halved tomatoes on the roof of their house to dry for several days in the blazing-hot Pugliese sun.

Many people, particularly outside Italy, have not tasted the homemade version. They assume that they will be like store-bought sun-dried tomatoes, which tend to be a bit leathery and tough, without much flavor. They seem like a faded, desiccated memory of a tomato, rather than a fragrant, intensified taste of summer days. Homemade sun-dried tomatoes are another thing entirely: fragrant and chewy but not tough, with complex, concentrated tomato flavor and a slight sweetness. 

Although it's not difficult, the trouble with making them at home is that many of us do not have the abundant outdoor space required or the time, or perhaps we lack consistent, strong sunshine, or live in highly polluted cities or bug-infested areas where perhaps drying food outdoors is not the best idea. 

The solution? You can easily dry them in your oven. For large quantities, you'll need to do this in batches; you should be able to fit about 2 pounds of tomato halves on a large baking sheet per batch. Once they are properly dried, they will last for many months in zipper-sealed plastic bags stored in a cool, dry place.

When you're ready to use them, you can use them directly in any recipe that calls for them or try the traditional method of marinating them in a jar full of olive oil and spices. They are great as pizza toppings or in pasta sauces, in salads or simply as-is, as part of an antipasto platter.

Note: Oblong tomatoes like San Marzano or Roma, or flavorful cherry tomatoes, work best.

What You'll Need

  • 2 pounds tomatoes (fresh, ripe San Marzano, Roma or cherry)
  • Fine sea salt

How to Make It

  1. Preheat the oven to 200 F (100 C), or the lowest setting possible. Resist the temptation to use a higher temperature to speed up the process, as then you'd be cooking the tomatoes, instead of drying them.
  2. Core the tomatoes and cut them in half lengthwise (from stem end to tip). Squeeze each half gently over a bowl to remove excess liquid and seeds. Make a small slit with the tip of a sharp paring knife in the back (peel side) of each tomato half, to help them dry.
  1. Place a drying rack on an aluminum foil-lined baking sheet and arrange the tomatoes, cut side up, in a single layer on the rack. Make sure there is a bit of space around each tomato and that they're not touching, so they can dry evenly. 
  2. Lightly sprinkle the tomatoes with salt.
  3. Place in the oven and bake until the tomatoes are dehydrated and a bit leathery, but not hard, brittle or crispy. They should still be somewhat chewy and flexible. Check them every hour during drying. Depending on your tomatoes and oven, this can take anywhere from about 6 to 12 hours.
