How to Roast and Preserve Tomatoes: A Step-by-Step Guide

Roasting and preserving tomatoes can be a rewarding way to enjoy the vibrant flavors of summer all year round. Whether you have an abundance of ripe tomatoes or need to use up green ones, this guide will walk you through the process of roasting, seasoning, and canning tomatoes. Not only will you learn how to prepare delicious roasted tomatoes, but you'll also discover tips for storing them safely.

Preparing the Tomatoes
1. Sorting and Washing:

Start by sorting through your tomatoes, separating the ripe ones from the green ones.
Wash the tomatoes thoroughly to remove any dirt or debris.
Dry the tomatoes to remove excess water, as this will help them roast more evenly.
2. Roasting the Tomatoes:

Slice the tomatoes in half and place them on lightly greased baking trays.
Preheat your oven and prepare to add some simple seasonings.
Seasoning and Roasting
3. Adding Seasonings:

Sprinkle salt over the tomatoes to enhance their natural flavor.
Use homegrown or dried herbs like thyme, rosemary, or basil to add aromatic flavors. Thyme, in particular, pairs well with tomatoes.
Chop a clove of garlic for each tray and distribute it evenly over the tomatoes. Roasting garlic with the tomatoes adds a rich, savory note.
4. Roasting:

Place the trays in the oven and roast the tomatoes until they are caramelized and tender. This process concentrates the flavors and brings out the sweetness of the tomatoes.
Preparing the Vinegar Concoction
5. Making the Vinegar Mixture:

In a bowl, mix lemon juice, wine vinegar, and balsamic vinegar. This mixture will add acidity and flavor to your preserved tomatoes.
Adjust the ratios to balance the flavors, ensuring the lemon juice does not overpower the mixture.

Canning the Tomatoes
6. Filling the Jars:

Once the tomatoes are roasted, transfer them to sterilized half-pint jars while still hot.
Pour the vinegar mixture over the tomatoes, ensuring they are fully submerged. This step is crucial for preservation.
Wipe the rims of the jars with vinegar to ensure a clean seal.

7. Water Bath Canning:

Place clean, fresh lids on the jars and secure them with rings.
Process the jars in a boiling water bath for 35 minutes. This method ensures that the jars are sealed and the contents are preserved safely.
Once the canning process is complete, allow the jars to cool, then remove the rings and wash the jars. Label and date them for future reference.
Storing and Enjoying

8. Storage:

Store your preserved tomatoes in a cool, dark place. Properly canned tomatoes can last for up to a year.
Use the tomatoes as a condiment, a side dish, or a topping for pasta. They pair wonderfully with crusty Italian bread or as part of a pizza topping.

9. Sharing the Bounty:

If you have an abundance of preserved tomatoes, consider sharing them with friends and family. They make a delightful homemade gift and are sure to be appreciated.
By following these steps, you can enjoy the taste of summer tomatoes all year long. Happy canning!
