How To Make Oven-Dried Tomatoes
Slice plum tomatoes lengthwise, sprinkle with salt, and bake at 200 to 250 degrees F until shriveled, but still slightly tender. This can take anywhere from 4 to 8 hours, depending on the size of the tomatoes.
The natural sweetness of the tomatoes concentrates as the water is slowly cooked out. Each plum tomato averages 11 calories, so you’ll get big flavor for a tiny amount of calories. An added bonus: cooking tomatoes ups the lycopene content, baking in more antioxidants.
Use dried tomatoes right away, or store packed in olive oil and herbs if desired. Use them to add a chewy bite of sweetness to salads, pasta, and sandwiches or blend into salad dressings or mayonnaise – they also make a gorgeous stuffing for chicken breasts.
