Roasting Tomatoes for Canning

Welcome to the wonderful world of preserving the summer’s bounty! Canning tomatoes is a great way to enjoy the taste of summer all year round. One of the best ways to prepare tomatoes for canning is by roasting them. Roasting tomatoes enhances their natural sweetness and adds a depth of flavor that is perfect for sauces, soups, and more. In this guide, we’ll walk you through the simple steps to roast tomatoes for canning.

Choose the Right Tomatoes

When it comes to roasting tomatoes for canning, it’s important to start with the best tomatoes. Look for ripe, firm tomatoes that are free from blemishes or bruises. Roma tomatoes are a popular choice for canning due to their meaty texture and low moisture content, but you can also use other varieties such as San Marzano or Amish Paste.

Prep and Preheat

Before you start roasting, preheat your oven to 400°F (200°C). While the oven is heating up, wash the tomatoes thoroughly and remove any stems. If you like, you can also cut the tomatoes in half to expose the seeds and flesh, but this step is optional.

Season and Roast

Place the prepared tomatoes on a baking sheet in a single layer. Drizzle them with olive oil and sprinkle with salt and pepper to taste. If desired, you can also add minced garlic or fresh herbs such as thyme or rosemary for extra flavor. Roast the tomatoes in the preheated oven for 30-40 minutes, or until they are soft and starting to caramelize around the edges.

Cool and Store

Once the tomatoes are done roasting, remove them from the oven and let them cool to room temperature. At this point, you can either use the roasted tomatoes immediately in your favorite recipes, or you can proceed with the canning process to preserve them for later use.

Canning Roasted Tomatoes

If you’re planning to can the roasted tomatoes, you’ll need to follow the proper canning procedures to ensure their safety and longevity. Here’s a basic overview of the canning process:

Prepare your canning jars and lids by washing them in hot, soapy water and sterilizing them in boiling water.
Fill the jars with the roasted tomatoes, leaving about 1 inch of headspace at the top.
Wipe the rims of the jars to remove any residue, then place the lids on top and screw on the bands until they are fingertip tight.
Process the jars in a boiling water bath for the recommended time based on your altitude and the size of the jars.
Once the processing time is complete, carefully remove the jars from the water bath and let them cool at room temperature. Check the seals to ensure they are airtight before storing the jars in a cool, dark place.
