How to Make Sun-Dried Tomatoes at Home: A Step-by-Step Guide
Discover easy methods for making your own sun-dried tomatoes and learn how to store and use them in your favorite dishes.
Sun-dried tomatoes bring vibrant flavor, a touch of sweetness, and a pleasant chewiness to a variety of dishes. Their concentrated taste is delightful in salads, pastas, breads, and snacks. While you can buy them at the store, homemade sun-dried tomatoes are fresher, more flavorful, and allow you to control the process from start to finish. In this comprehensive guide, you’ll learn how to make sun-dried tomatoes using your oven, a food dehydrator, or the traditional sun-drying method. Plus, get tips on storage, usage, and answers to frequently asked questions.
What Are Sun-Dried Tomatoes?
Sun-dried tomatoes are simply ripe tomatoes that have had most of their moisture evaporated, typically by exposure to the sun, though home cooks often use an oven or dehydrator. The drying process concentrates both the flavor and nutrients, yielding a tomato that’s sweet, tangy, and slightly leathery — perfect for a variety of culinary uses. The classic version is made with small, sweet tomatoes like Roma or plum, but any variety can be dried, each bringing its own unique flavor.
Why Make Sun-Dried Tomatoes at Home?
- Better Flavor: Home-dried tomatoes capture more of the ripe, tomato-y intensity of your chosen variety than those typically found in stores.
- No Additives: Homemade sun-dried tomatoes have no preservatives or sulfites.
- Cost-Effective: Seasonally abundant tomatoes can be preserved for year-round use.
- Customizable: Adjust seasoning, thickness, and drying method to your preference.
Best Tomato Varieties for Drying
While you can dry nearly any type of tomato, certain varieties yield optimal results:
- Roma (Plum) Tomatoes: Dense, low-moisture, and meaty, making them ideal for drying.
- Cherry or Grape Tomatoes: Sweet, bite-sized, and concentrate sugars beautifully.
- Campari or Cocktail Tomatoes: Slightly larger, great flavor when dried.
- Heirloom Varieties: For unique tastes, but higher moisture content may require longer drying times.
Choose ripe, but not overripe, tomatoes for best results.
Preparing Tomatoes for Drying
Proper preparation ensures even drying and beautiful results:
- Wash tomatoes thoroughly and pat dry.
- Remove stems and slice each tomato in half lengthwise. For larger tomatoes, cut into thick slices (about 1/2 to 3/4 inch).
- Remove seeds if desired, but it’s not necessary.
- Gently squeeze out excess juice for faster drying.
- Lay cut side up on a parchment-lined baking sheet or dehydrator tray.
- Sprinkle lightly with salt, which helps draw out moisture and intensify flavor. Optional: season with herbs (oregano, thyme, basil) or a drizzle of olive oil.
Methods for Making Sun-Dried Tomatoes
There are three primary ways to make sun-dried tomatoes at home: in the oven, using a food dehydrator, or the traditional sun-drying method. Each has its pros and cons.
1. Oven-Dried Tomatoes
Oven drying is the most accessible and reliable method for most home cooks, especially if you lack consistently hot, dry weather.
- Preheat your oven to 200°F (or the lowest setting available, 175–225°F).
- Arrange prepared tomatoes cut side up on parchment-lined baking sheets.
- Bake for 2–4 hours for cherry tomatoes, up to 6–12 hours for larger tomatoes. Rotate pans every hour or so for even drying.
- Check frequently at the end — tomatoes should be dry, shrunken, and chewy, but not brittle or burnt.
- Cool completely on the pan before transferring for storage.
Tip: Leave oven door slightly ajar for moisture to escape.
2. Dehydrator-Dried Tomatoes
Food dehydrators are designed for low, even drying, and can produce the best texture with less risk of burning.
- Arrange tomato slices on dehydrator trays in a single layer, cut side up.
- Set dehydrator to 135°F (57°C).
- Dry for 8 to 12 hours, checking occasionally. Drying time varies by tomato size, moisture level, and humidity.
- Tomatoes are done when fully dry but still pliable, not crisp.
3. Traditional Sun Drying
For the classic method, you’ll need consistently hot, sunny weather with low humidity and patience:
- Arrange prepared tomatoes on racks or mesh trays for good air circulation.
- Cover lightly with cheesecloth to keep off insects and dust.
- Place outside in direct sunlight for 4–10 days, bringing inside at night to prevent dew.
- Flip tomatoes occasionally to ensure even drying. Tomatoes should be leathery and fully dried throughout when finished.
Note: If your climate isn’t reliably hot and dry, oven or dehydrator methods will yield safer, more predictable results.
How to Know When Sun-Dried Tomatoes Are Done
Determining when your tomatoes are perfectly dried is crucial for quality and storage safety. Here’s what to look for:
- Tomatoes are reduced in size by 60–70%, with a deep, rich color.
- Texture should be dry but still flexible, not sticky or wet inside.
- If sliced in half, no visible moisture should appear inside.
- Overly crispy tomatoes are overdone; if too soft or moist, keep drying.
Let dried tomatoes cool completely before packing to prevent condensation inside containers.
Ways to Store Sun-Dried Tomatoes
Proper storage keeps homemade sun-dried tomatoes fresh and safe for months. Choose your preferred storage method:
1. Airtight Containers
- Place cooled sun-dried tomatoes in glass jars or airtight containers.
- Store in a cool, dark, dry place for up to 6 months.
- For longer storage (up to a year), keep in the refrigerator or freezer.
2. In Olive Oil
- For jarred tomatoes packed in oil, first ensure they are completely dry to prevent spoilage.
- Pack tomatoes into sterilized jars, adding garlic, herbs, or chili flakes if desired.
- Pour extra-virgin olive oil over tomatoes until fully submerged.
- Refrigerate and use within 2 weeks. Oil-packed tomatoes (unless commercially vacuum packed) are not shelf stable because of botulism risk.
3. Freezing Sun-Dried Tomatoes
- Arrange dried tomatoes in a single layer on a baking sheet. Freeze, then transfer to zip-top bags or containers for up to 1 year.
- No thawing is needed—use straight from the freezer.
Ways to Use Sun-Dried Tomatoes
Homemade sun-dried tomatoes are a versatile pantry staple. Here are some popular ways to use them:
- Pasta & Risotto: Chop and stir into pasta dishes, risottos, and grain salads.
- Bread & Focaccia: Add to bread dough or focaccia for bursts of tomato flavor.
- Salads: Toss sliced sun-dried tomatoes into leafy salads, grain bowls, or caprese salads.
- Pizza: Sprinkle on top of pizza before baking for tangy-sweet bites.
- Snacking: Eat as-is for a nutritious, flavorful snack.
- Pesto & Dips: Blend into pestos, hummus, or dips for extra dimension.
- Sandwiches & Wraps: Use in sandwiches, paninis, or wraps instead of fresh tomatoes for concentrated flavor.
Tips for the Best Homemade Sun-Dried Tomatoes
- Consistency: Slice tomatoes to a uniform thickness to ensure even drying.
- Spacing: Arrange slices in a single layer, not touching, for airflow.
- Don’t Oversalt: Lightly salt to avoid overpowering the tomatoes’ natural sweetness.
- Use Ripe Fruit: Select fully ripe, but not mushy, tomatoes. Avoid underripe or overripe fruit for best results.
- Test for Doneness: Check frequently near the end of drying, as times can vary.

Frequently Asked Questions (FAQs)
Do I have to use Roma tomatoes for sun-dried tomatoes?
No, while Roma tomatoes are traditional due to their low moisture content and rich flavor, you can use cherry, grape, or other plum-shaped tomatoes. Even slicing varieties like heirlooms can be used, but they may take longer to dry and have a slightly different texture.
How long do homemade sun-dried tomatoes last?
Stored in an airtight container in the refrigerator, they last 6–9 months. In the freezer, up to a year. Oil-packed, refrigerated tomatoes should be consumed within 2 weeks due to safety.
Is it safe to make sun-dried tomatoes in oil at home?
Extra caution is needed as botulism bacteria can grow in low-oxygen environments like oil. Only pack thoroughly dried tomatoes in oil and refrigerate. Eat within 2 weeks, and never store at room temperature.
Can I season sun-dried tomatoes before drying?
Yes! A sprinkle of dried herbs or a drizzle of olive oil enhances flavor. Go light, as flavors concentrate during drying.
How do I rehydrate sun-dried tomatoes?
Soak dried tomatoes in hot water or broth for 15–20 minutes until plump. For extra flavor, use warm olive oil or wine.
Can I dry tomatoes in the microwave?
The microwave isn’t suited to drying large batches of tomatoes—it’s hard to control doneness and may result in tough or burnt spots. Oven or dehydrator methods are far better for quality and consistency.
