One summer, as I sat in my grandmother’s sunlit kitchen, she introduced me to the art of preserving the season’s bounty. I watched her skillfully handle plump, ripe tomatoes, transforming them into jars of rich, flavorful preserves that would brighten our winter meals. Inspired by those cherished memories, I decided to explore oven-canned tomatoes. This method captures the essence of sun-ripened tomatoes, infusing them with aromatic herbs and garlic, and preserving their flavor to be savored throughout the year.

 

There’s something magical about opening a jar of these oven-canned tomatoes on a cold winter’s evening. The aroma immediately transports you back to the warmth of summer, reminding you of sunlit gardens and bountiful harvests. As I roast the tomatoes, the house fills with a deliciously rich scent, blending sweet tomato with the earthy aroma of basil and oregano. It’s a simple yet satisfying process, one that connects me to generations of home cooks who have preserved their garden treasures with love and care.

Ingredients

Fresh, ripe tomatoes

Olive oil

Salt

Garlic (optional)

Herbs like basil, oregano, or thyme (optional)

Equipment

• Baking sheet
• Sharp knife
• Cutting board
• Sterilized jars with lids
• Oven
• Cooling rack

Directions

Preheat your oven to 275°F (135°C). This low, slow roasting process will intensify the natural sweetness of the tomatoes and bring out deep, rich flavors.

Wash and dry your tomatoes, then slice them in half. Choose the ripest tomatoes for the best flavor. Removing any blemishes ensures a pristine end product.

Place the tomato halves on a baking sheet, cut side up. Make sure they are arranged in a single layer to roast evenly.

Drizzle the tomatoes with olive oil and sprinkle with salt. A good quality olive oil will enhance the flavor, while the salt helps to draw out moisture and concentrate the sweetness.

If desired, add minced garlic and fresh herbs for extra flavor. Scatter the garlic and herbs over the tomatoes. This step is optional but highly recommended for a burst of flavor.

Roast the tomatoes in the preheated oven for 3-4 hours, or until they are soft and caramelized. The low heat slowly draws out the moisture, leaving you with beautifully roasted, intensely flavored tomatoes.

Remove the tomatoes from the oven and let them cool completely. This cooling step is crucial for the tomatoes to firm up slightly and be easier to handle.

Once cooled, transfer the tomatoes to sterilized jars and cover them with olive oil. This step ensures that the tomatoes are submerged in oil, which helps to preserve them.

Seal the jars tightly and store them in a cool, dark place for up to 6 months. Properly sealed jars can last up to half a year, bringing a taste of summer to your table whenever you need it.

Tips and Variations

• Use different herbs: Experiment with rosemary, thyme, or even a sprinkle of crushed red pepper for a bit of heat.
• Roasting time: Adjust the roasting time according to the size and water content of your tomatoes. Smaller cherry tomatoes might need less time, while larger beefsteaks might require more.
• Storing: Once opened, store the jars in the refrigerator and use them within a week.
