Oven-Dried Tomatoes

We owned an organic greenhouse and business that included classes. I had 100 tomato varieties to work with, so I started oven-drying them and taught my students, too. —Sue Gronholz, Beaver Dam, Wisconsin
  • Total Time
    Prep: 15 min. Bake: 5 hours
  • Makes
    4 servings


  • 8 plum tomatoes
  • Ice water
  • 1/4 cup olive oil
  • 1/4 cup minced fresh basil
  • 4 garlic cloves, minced
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper


  • Preheat oven to 250°. Fill a large saucepan two-thirds with water; bring to a boil. Cut a shallow “X” on the bottom of each tomato. Place tomatoes, a few at a time, in boiling water just until skin at the “X” begins to loosen, about 30 seconds. Remove and immediately drop into ice water. Pull off and discard skins.
  • Cut tomatoes in half lengthwise. Combine tomatoes, oil, basil, garlic, salt and pepper; toss to coat. Transfer tomatoes, cut side up, to a greased 15x10x1-in. baking pan. Roast until tomatoes are soft and slightly shriveled, about 5 hours. Cool completely; refrigerate.

    I used a mix of all my home-grown tomatoes, not just plum. I skipped the first step of removing the skins because I like them on. I also didn't roast mine the full five hours. The ingredients are a nice combination and the taste of these tomatoes is really good. Next time I will try roasting the full five hours. I am still very pleased with the result of a lesser roasting time.

    Wow! It took a little time to peel the plum tomatoes, but once that was done, all was easy. The tomato halves are tossed with a delicious mixture of olive oil, minced fresh basil (I used the tube stuff.), fresh garlic, salt and pepper. I sprinkled on a touch of crushed red pepper because we like spicy. Instead of using the oven, I used my dehydrator, and it worked perfectly w/o heating up the kitchen. I am planning to use them in pasta and vegetable salads. I will definitely make these again!
