Sun-dried tomatoes are a culinary delight, offering a rich, concentrated flavor that enhances a wide variety of dishes. While often found packed in oil, the oil-free, or dry-packed, variety is a great alternative for those watching their calorie or fat intake. The process of sun-drying tomatoes removes most of their water content, which concentrates their nutrients and, consequently, their calories per gram compared to fresh tomatoes.
Calorie and Nutritional Profile of Dry-Packed Sun-Dried Tomatoes
Unlike their oil-drenched counterparts, dry-packed sun-dried tomatoes are relatively low in fat, making them a more calorie-efficient choice. A standard 100-gram serving, which is roughly equivalent to a little less than one cup, contains a significant amount of concentrated nutrients.
Here is a breakdown of the nutritional profile for approximately 100g of dry-packed sun-dried tomatoes, based on several sources:
- Calories: 258 kcal
- Protein: 14.1 g
- Carbohydrates: 55.76 g
- Total Fat: 3 g
- Fiber: 12.3 g
- Potassium: 3427 mg
- Iron: 9 mg
- Vitamin C: 39 mg
As you can see, these tomatoes are not only flavorful but also a potent source of essential minerals like potassium and iron, along with dietary fiber. The removal of water during the drying process is responsible for this dense nutritional concentration. For perspective, fresh tomatoes contain a much lower calorie count and a higher water content, leading to a less intense nutrient profile per unit of weight.
Nutritional Comparison: Oil-Packed vs. Dry-Packed
Understanding the difference in calories and fat between sun-dried tomatoes packed in oil and those without oil is crucial for dietary management. The addition of oil, typically olive oil, significantly increases the calorie and fat content.
| Nutrient (per 100g) | Dry-Packed (Approx.) | Oil-Packed (Approx.) | Difference |
|---|---|---|---|
| Calories | 258 kcal | 240-250 kcal (drained) | Drained oil-packed can be similar or lower, but actual content can vary greatly depending on oil absorption. The key is the high fat content in oil-packed. |
| Fat | 3 g | 15 g | Significant fat increase |
| Protein | 14.1 g | 6 g | More protein in dry-packed |
| Carbohydrates | 55.76 g | 26 g | Higher carb concentration in dry-packed |
This comparison highlights that while the total calorie count for a 100g serving can be misleading due to varying weights and preparation methods (drained vs. undrained), the fat content is the primary differentiator. Dry-packed sun-dried tomatoes are the clear winner for those seeking a lower-fat, lower-calorie option without sacrificing flavor.
How to Incorporate Sun-Dried Tomatoes into a Healthy Diet
Dry-packed sun-dried tomatoes are incredibly versatile and can be used in numerous ways to boost flavor without adding unnecessary fat. Here are some tips and ideas:
- Rehydrate for recipes: Before using, soak the dry tomatoes in hot water for about 10-15 minutes to soften them. This process also reduces their sodium content if they were packed in salt.
- Salads: Chop them finely and sprinkle over green salads, pasta salads, or grain bowls for a chewy, tangy texture.
- Sauces and Dressings: Purée rehydrated tomatoes into sauces, dips, and vinaigrettes for a depth of flavor.
- Baking: Add to bread dough, muffins, or savory scones. They also work well in homemade crackers.
- Stews and Soups: Toss a handful into soups, stews, or chili to intensify the tomato flavor. They are also a great addition to lentil or bean dishes.
- Protein Topping: Use as a topping for grilled chicken, fish, or tofu to add a concentrated tomato flavor. Combine with fresh herbs and a little lemon juice for a simple, vibrant sauce.
Conclusion: A Flavorful and Healthy Choice
Dry-packed sun-dried tomatoes are a calorie-concentrated but nutrient-dense ingredient that can be a healthy addition to your diet. By avoiding the versions packed in oil, you can enjoy their intense flavor and nutritional benefits without a significant increase in fat. For anyone managing their calorie intake, it's a wise choice to use dry-packed tomatoes and rehydrate them, controlling both flavor and nutritional impact. Incorporating them into various recipes allows you to enhance meals with a bold, naturally sweet, and savory element.
How to Prepare Dry-Packed Sun-Dried Tomatoes
- Selection: Choose dry-packed sun-dried tomatoes from the grocery store. Check the packaging to ensure no oil has been added.

Tips for Cooking with Sun-Dried Tomatoes
- Manage Sodium: Be mindful that some dry-packed varieties are preserved with salt, increasing their sodium content. Rinsing or soaking can help reduce this.
- Boost Bioavailability: The drying process increases the bioavailability of lycopene, a potent antioxidant found in tomatoes. Pairing with a small amount of healthy fat (like a little avocado or nuts) can further enhance absorption.
- Storage: Store dry-packed sun-dried tomatoes in an airtight container in a cool, dark place. Once rehydrated, they should be refrigerated and used within a few days.
- Flavor Intensity: A little goes a long way. The flavor of sun-dried tomatoes is highly concentrated, so start with a small amount and adjust to taste.
Health Benefits Beyond Calories
Dry-packed sun-dried tomatoes are also packed with other health benefits, including being a great source of antioxidants like lycopene, and essential vitamins and minerals, which can support overall health. Their high fiber content also aids in digestive health.
