How to Preserve Tomatoes for Winter: 6+1 Ideas Worth Trying

2026. 08. 10.

Few ingredients capture summer quite like a ripe, sun-ripened tomato. When home gardens overflow with fruit and markets let you pick through kilos of juicy tomatoes, it's worth thinking ahead a little. Tomatoes can be preserved in countless forms, so you can not only save your surplus but enjoy the taste of summer all winter long. If you'd like to go beyond traditional canning, here are 6+1 ideas, including both classic favorites and a few more unusual treats.

1. Tomato juice - the pantry's timeless classic

If you were to make just one thing for winter, tomato juice is almost always a good choice. It's an excellent base for soups, sauces, and stews, but can also be enjoyed on its own with a pinch of celery or basil. You'll get the best results if you first cook the tomatoes, then remove the skins and seeds with a food mill. After that, all that's left is a short second boil, filling into sterile jars, and steam-processing.

Tip: If you're making a larger batch, a large-capacity pot speeds up the work considerably.

2. Lecsó base (tomato and pepper stew base)

Few preserves are more practical than a ready-made lecsó base. In summer, meaty tomatoes and crisp peppers are still easy to find, but in winter all you need to do is open the jar. The traditional version is made with onion, though many prepare it without onion so it can be used more freely later. It works as the base for lecsó, stew, shakshuka, or even pasta dishes. It's one of the best ways to make everyday cooking easier all winter long, in exchange for just a few hours of work now.

3. Sun-dried tomatoes

If you're after a truly intense tomato flavor, try drying them. Slowly dried tomatoes lose most of their water content while their flavors become almost concentrated. Use them on pizza, in salads, sandwiches, or homemade breads. Once dried, cover them with olive oil, season with garlic and herbs, and they'll keep for months.

Tip: Although this can be done in the oven, a food dehydrator makes the process much easier, working at a steady temperature while needing minimal supervision.

4. Pickled tomatoes

Cucumbers and peppers aren't the only vegetables that can be pickled. Smaller cocktail or vine tomatoes are also excellent for pickling in vinegar or lightly fermenting. Pickled tomatoes pair wonderfully with grilled dishes, cold platters, roasts, or even as an addition to a cheese board. A little garlic, mustard seed, dill, and pepper give them an entirely new character. If you want something truly special in your pantry, this one is well worth trying.

5. Homemade pizza sauce

One of the most important elements of a good pizza is the tomato sauce. In summer, you'll find far more flavorful ingredients than what stores offer in winter. Cook the tomatoes together with garlic, oregano, basil, and a little olive oil, then reduce to the desired thickness. Jarred up, it will be on hand all winter whenever you want to make pizza, lasagna, or pasta sauce. That way, you won't have to start from scratch every time you cook.

6. Passata - the foundation of Italian cooking

Passata is essentially a smooth, silky tomato puree pushed through a sieve, and it's one of the most important pantry staples in Italian households. Since it contains no spices or other vegetables, it's extremely versatile. It can become the base for tomato soup, bolognese sauce, baked dishes, or any tomato-based meal. If you cook regularly, passata is one of the most practical forms of preserving, since you can always season it to fit the specific recipe.

+1. Tomato jam

It might sound surprising at first, but tomatoes also make a fantastic jam. The natural sweetness of ripe tomatoes pairs beautifully with brown sugar, lemon, cinnamon, or even a pinch of chili. Tomato jam isn't the classic companion to a breakfast roll - it's much more of a special culinary experience. It's perfect alongside cheeses, grilled meats, burgers, or festive cheese boards. If you love unusual flavors, this could be the most exciting preserving project of this year's season.

The secret to successful preserving is proper preparation

Whether you're making a few jars of tomato juice or an entire pantry's worth of delicacies, the right tools save a great deal of time and energy. Large-capacity pots, food mills, canning jars, food dehydrators, vacuum sealers, and other kitchen tools used for sterilizing not only make preserving faster, but safer too. What's more, you can easily get the right tools from GAMMO's range, so everything is in place for preserving to be truly smooth and efficient.

After all, jars of preserves made from summer's finest tomatoes are at their most valuable when, on a cold January evening, a jar comes out of the pantry and a single spoonful brings back the taste of sunshine.
