Preserving tomatoes at home through canning is a wonderful way to extend the shelf life of your harvest and enjoy their freshness throughout the year. Canning might seem intimidating at first, but with the right guidelines, it’s both fun and rewarding. Here’s a guide on home canning tomatoes, step by step.

1. Gather Necessary Supplies
Before starting, ensure you have all the necessary equipment:
- Glass canning jars with two-part lids (seal and ring)
- A large pot or canner
- Canning rack
- Jar lifter
- Funnel, ladle, and bubble remover (or a non-metallic spatula)
2. Prepare Your Tomatoes
- Wash your tomatoes thoroughly to remove any dirt or debris.
- To peel, make a small “X” incision at the bottom of each tomato, blanch them in boiling water for 30-60 seconds, and then transfer them to cold water. The skins should slide off easily.
- Core the tomatoes and remove any blemishes.
- Cut the tomatoes as desired (halved, quartered, or diced).
3. Fill the Jars
- You can can tomatoes with or without added liquid. For a juicier consistency, crush the tomatoes slightly and add them to the jar, letting their juices fill the space. For a firmer consistency, pack tomatoes into the jar and cover them with water or tomato juice.
- Leave a 1/2-inch headspace at the top of the jar.
- Use a bubble remover or spatula to remove any air bubbles inside the jar.
- Wipe the rim of the jar clean and place the lid on, securing it with the ring. Do not overtighten.
4. Process the Jars
- Boil water in your pot or canner.
- Place the jars on the canning rack and lower them into the boiling water. Ensure they’re covered by at least 1 inch of water.
- Process pint jars for 40 minutes and quart jars for 45 minutes.
- After the processing time, turn off the heat and let the jars sit for 5 minutes.
- Remove the jars using the jar lifter and place them on a clean towel in a draft-free spot.
5. Check the Seal and Store
- After 12-24 hours, check the lids to ensure they’ve sealed properly. They shouldn’t flex when pressed.
- Store sealed jars in a cool, dark place for up to a year. Any jars that didn’t seal can be refrigerated and consumed within a week.
Tips and Tricks
- Acidity matters: Tomatoes are borderline in terms of acidity for safe canning. To ensure safety, you can add two tablespoons of lemon juice or half a teaspoon of citric acid to each quart jar.
- Seasoning: Feel free to add some herbs or spices like basil, oregano, or garlic to your jars for added flavor.
- Storing: Store any unsealed jars in the refrigerator and consume within a few days.
Home canning tomatoes is an age-old tradition that allows you to enjoy the bounties of your garden all year round. Not only does it make for a rewarding experience, but it also ensures that you have a steady supply of preserved tomatoes for your culinary creations. With practice, you’ll find that canning becomes a cherished seasonal routine. Happy canning!
