Ingredients for Stuffed Sun-Dried Tomatoes

Here’s what you’ll need to make about 2 jars (500 ml each):

• 500 g sun-dried tomatoes
• 500 g canned tuna in oil, drained
• 20 g fresh thyme leaves
• 1 teaspoon dried oregano
• 100 g pine nuts
• 20 g salt-packed capers, rinsed
• 1 untreated lemon (zest only)
• 5–6 fresh bay leaves
• 1 liter white wine vinegar
• Extra-virgin olive oil (enough to cover)

For kitchen prep, having reliable kitchen islands and carts can provide extra workspace for mixing and stuffing.

Step-by-Step Preparation

1. Prepare the Sun-Dried Tomatoes

Rinse the sun-dried tomatoes in warm water to soften them slightly. Bring the white wine vinegar to a boil in a large pot, add the drained tomatoes, and cook for 2–3 minutes. Drain them, spread on a clean kitchen towel, cover with another towel, and press gently to dry. Let them air-dry for about 2 hours.

2. Soak the Capers and Prep the Herbs

Soak the salt-packed capers in warm water for 10 minutes to remove excess salt. Strip the thyme leaves from the stems and chop finely. Mix with dried oregano. Zest the lemon using a fine grater lined with parchment paper to catch all the zest without waste.

3. Make the Tuna Filling

Drain the tuna thoroughly. In a food processor, combine the tuna, pine nuts, rinsed and dried capers, lemon zest, oregano, and thyme. Pulse until you get a coarse, spreadable paste. Roll the mixture into small walnut-sized balls.

4. Stuff the Tomatoes

Place one tuna ball into each sun-dried tomato and press lightly to secure. Layer the stuffed tomatoes in sterilized 500 ml jars, alternating with fresh bay leaves. Pack them snugly but not too tight.

5. Preserve in Oil

Fill the jars with extra-virgin olive oil, leaving about 1 cm of headspace. Tap the jars on the counter to release air bubbles. Seal tightly with sterilized lids. Place the jars in a large pot, cover with cold water, and bring to a boil. Sterilize for 30 minutes from the moment the water boils. Let cool completely before storing in a cool, dark place.

For easy jar handling and storage, consider a sturdy storage bench or a dedicated shelving unit in your pantry.

How to Serve Stuffed Sun-Dried Tomatoes

Frequently Asked Questions

Can I use fresh tomatoes instead of sun-dried?

No, this recipe relies on the concentrated flavor and chewy texture of sun-dried tomatoes. Fresh tomatoes would release too much water and spoil the preservation.

Do I have to sterilize the jars?

Yes, sterilization is essential for long-term storage without refrigeration. Skipping this step risks bacterial growth.

Can I substitute the tuna?

Absolutely. Anchovies, smoked salmon, or even a vegetarian filling with olives and sun-dried tomato paste work well.

How do I know if the jars are sealed properly?

After cooling, press the center of each lid. If it doesn’t pop back, the jar is sealed. Store any unsealed jars in the fridge and use within a week.

What if I don’t have a food processor?

You can finely chop the tuna, pine nuts, and capers by hand. It will be more rustic but still delicious.
