Preserve Fresh Tomatoes for 2 Years — No Vinegar Needed!
Enjoy Garden-Fresh Flavor Year-Round
Nothing compares to the rich, sweet taste of ripe summer tomatoes picked at their peak. Imagine opening a jar in the middle of winter and finding all that vibrant flavor still perfectly preserved, ready to transform your pasta, soups, or stews. With this reliable and natural method, you can enjoy the true taste of summer for up to two years—without using any vinegar or artificial preservatives.
Forget about bland store-bought tomatoes or overly sour canned goods. This technique is easy, requires minimal ingredients, and will make the most out of your garden’s bounty or the best picks from your local market.
Why This Preservation Method Is a Game-Changer
- No vinegar or chemicals: Pure, natural tomato flavor is maintained.
- Long shelf life: Tomatoes stay fresh for up to 24 months on your pantry shelf.
- Simple process: Only a few steps, no complicated equipment needed.
- Versatile uses: Homemade tomato preserves are perfect for sauces, stews, soups, risotto, and more.
Selecting the Best Tomatoes
The foundation of a delicious preserve is, of course, the tomato itself. Choose ripe, juicy tomatoes—ideally homegrown or sourced from a local farmer’s market. Varieties that detach easily from the stem tend to be perfectly ripe and flavorful. If your tomatoes are still a bit firm, let them sit at room temperature for a day or two; this extra ripening deepens their sweetness and enhances the overall taste of your preserve.
Pro tip: Always avoid tomatoes with blemishes or soft spots, as these can reduce the shelf life and safety of your finished product.

How to Preserve Tomatoes Step by Step
1. Sterilize Jars and Lids
Begin by washing your jars and lids with hot, soapy water. Rinse thoroughly. Submerge them in boiling water for several minutes to fully sterilize. Place the jars upside-down on a clean towel to air-dry. This step is crucial for preventing spoilage and maintaining freshness over time.
2. Prepare the Tomato Puree
Wash the tomatoes and cut them into large chunks, removing any stems or blemishes. Blend the tomatoes in batches until you have a smooth puree. Pour this puree into a large, heavy-bottomed pot and bring it to a gentle boil. As it heats, skim off any foam that rises to the surface. Let the puree simmer for about 10 minutes to intensify the flavor and reduce excess water, then remove from heat.
3. Fill the Jars
Gently prick a few whole tomatoes with a fork and place them into the sterilized jars—this provides extra texture in your final preserve. Next, pour the hot tomato puree over the whole tomatoes in each jar, leaving about 1 inch of headspace at the top. Drop in a few fresh basil leaves for added flavor and a hint of summer aroma.
4. Seal and Create a Vacuum
Seal the jars tightly with the sterilized lids while everything is still hot. To ensure a strong vacuum seal and maximize shelf life, place the sealed jars into a large pot of boiling water, making sure the jars are fully submerged. Boil for 10 to 15 minutes. This process, called water-bath canning, drives out air and ensures a tight, safe seal.
5. Cool and Store
Carefully remove the jars from the hot water and let them cool on a towel at room temperature. As they cool, you should hear a soft “pop”—that’s the vacuum seal forming. After the jars are completely cool, check that the lids are firmly sealed (the center should not flex when pressed). Store the jars in a cool, dark, and dry place. Avoid temperature fluctuations for the best results.
Important Notes & Safety Tips
- Always check jars before use. If the seal is broken or the color, smell, or texture seems unusual, discard the contents immediately.
- A proper vacuum seal is critical for safe long-term storage. If a jar hasn’t sealed, refrigerate and use within a week.
- This method contains no vinegar, so precise sterilization and sealing are essential.
- Use your preserved tomatoes for pasta sauces, hearty soups, pizza toppings, casseroles, and more.
