Crafting tomato preserves doesn’t have to be complicated. With just a few ingredients and a little patience, you can enjoy the taste of fresh tomatoes all year round. No more relying on store-bought alternatives or making trips to the supermarket!

Tomato preserves are incredibly versatile and can be used in a variety of dishes. Whether you want to enhance your favorite spaghetti sauce or add flavor to other culinary creations, tomato preserves are a game-changer. They bring homemade goodness to your meals, even when fresh tomatoes are out of season.

While summer is the best time to preserve tomatoes, there’s a method that extends their shelf life up to two years. All you need are some ripe tomatoes, ideally from your own garden, and plenty of basil.

The key to delicious tomato preserves lies in the ripeness and variety of tomatoes you use. To ensure you’re choosing the right ones, consult your local greengrocer. It’s also a good idea to prepare the sauce a couple of days after purchasing the tomatoes, as this can enhance the final product.

One simple way to determine whether tomatoes are ripe is by checking if the stem easily detaches from the fruit. And remember, when you open a jar of tomato sauce, it should taste, look, and smell the same as when you first made it. Any changes in flavor, color, or aroma indicate spoilage, and the sauce should be discarded.

Proper sterilization of jars is crucial for successful preservation. Here’s a recipe using around 7 kg of tomatoes that will yield approximately 3 2L jars:


  • 7 kg of tomatoes
  • Basil, to taste
  • Boiling water for sterilizing jars

Preparation time: 15 minutes

Cooking time: 30 minutes

Shelf life: 2 years


  1. Slice and blend the tomatoes into a puree, then transfer the puree to a saucepan and bring it to a boil.
  2. Skim off any foam that forms on the surface while it’s boiling. Continue boiling for a couple more minutes before turning off the heat.
  3. Pierce the tomatoes with a fork and place them in sterilized glass jars. Fill the jars with the tomato puree.
  4. To seal the jars, immerse them in boiling water in a pan to create a vacuum. Store the sealed jars in a cool, dry place.

Ensuring a tight seal and vacuum is essential for extending the shelf life of your tomato preserves. With this foolproof method, you’ll always have homemade preservatives at your fingertips, ready to elevate any dish, from a quick spaghetti to flavorful seasonings! Enjoy the delicious taste of summer all year round.
