Preserve Tomatoes for Up to 2 Years (No Vinegar Needed)
If you want to store fresh tomatoes long-term without vinegar, this classic jar method is a great option. Done correctly, it helps tomatoes stay juicy, aromatic, and ready for cooking whenever you need them.
What You’ll Need
- Fresh, firm tomatoes (skip soft or overripe ones)
- Glass jars with airtight lids
- Coarse salt (optional, for added keeping power)
- Boiling water
- A large pot for sterilizing and heat-processing the jars
Step-by-Step: How to Can Tomatoes Without Vinegar
-
Clean and dry the tomatoes well.
Rinse thoroughly, then dry completely so no excess moisture remains on the skins. -
Fill sterilized jars with tomatoes.
Arrange them carefully and avoid pressing or crushing them. -
Add boiling water.
Bring water to a full boil and pour it into each jar until the tomatoes are fully covered. -
Seal immediately.
Close the lids tightly while the water is still hot. -
Process the sealed jars for a vacuum seal.
Put the jars into a large pot, cover them with water, and boil for 40 minutes to help create a strong seal. -
Cool and store.
Let jars cool naturally at room temperature, then move them to a cool, dark storage area.
Why This Tomato Preservation Method Works
- Vacuum sealing helps prevent bacterial growth, keeping tomatoes safe and stable for long storage.
- No vinegar is used, so the tomatoes keep a clean, natural tomato flavor.
- Suitable for whole tomatoes, peeled tomatoes, or even tomato purée, depending on how you prefer to pack them.
Storage and Safety Tips
- Store jars in a cool, dark pantry, ideally below 21°C / 70°F.
- After opening, refrigerate and use within 7 days.
- If any jar leaks, smells unusual, or seems spoiled, discard it right away.
Final Notes
With this traditional technique, you can enjoy tomatoes year-round while keeping their original taste—without vinegar or added preservatives.
