What Are Sun-Dried Tomatoes?

Sun-dried tomatoes are ripe tomatoes that have been dehydrated—traditionally by placing them in direct sunlight—to remove most of their water content. This process:

Concentrates Flavor: Sugar, acid, and umami components intensify.
Alters Texture: Flesh becomes leathery and chewy, ideal for rehydration or direct use.
Preserves Tomatoes: Extends shelf life from days to months or years, depending on packaging.

Common tomato varieties for drying include Roma (plum), San Marzano, and other meaty types with low seed counts.

History and Traditional Methods

Origins in the Mediterranean

Italy & Greece: Coastal growers historically laid halved tomatoes on clay tiles or clean stones under the hot sun.
Roman Era: Dried tomatoes appear in ancient texts describing preservation of surplus harvests.
Spread to the World: Italian immigrants introduced sun-dried tomatoes to the Americas in the 19th and 20th centuries.

Traditional Drying Steps

Selection: Pick fully ripe, blemish-free tomatoes (Roma are ideal).
Preparation: Wash, halve or quarter, scoop out seeds optionally.
Seasoning (Optional): Lightly salt to draw moisture and enhance flavor.
Sun Drying: Place cut-side up on racks or trays, cover with mosquito netting, and let sun and breeze dehydrate over 5–10 days, turning occasionally.
Oiling & Packing: Once leathery, store in olive oil with herbs for preservation, or dry completely for shelf storage.

Types and Varieties

By Drying Method

Sun-Dried: Natural, eco-friendly, time-intensive, retains most flavor nuances.
Oven-Dried: Faster (8–12 hours at 60–90 °C), more control over hygiene and weather.
Dehydrator-Dried: Consistent results, programmable humidity and temperature.

By Packaging

Dry-Packed: Fully dehydrated; require rehydration before use.
Oil-Packed: Stored in oil with garlic, herbs, and spices; ready to eat, richer flavor, shorter shelf once opened.
Vacuum-Sealed: Extended shelf life, retains texture and color, ideal for long-term storage.
