III. Top 7 Ways to Preserve Tomatoes for Later Use

There are many ways to preserve tomatoes, but some methods are more popular and effective than others. Here are the top seven ways to preserve tomatoes:

  3. Drying
  4. Pickling
  5. Jamming

Canning is a method of preservation that involves cooking tomatoes in a jar at high temperatures to kill any bacteria that may cause spoilage. Here’s how to can tomatoes:

  1. Start by washing your jars and lids in hot, soapy water. Rinse them thoroughly and place them in a large pot of water to boil for at least 10 minutes.
  2. While your jars are boiling, prepare your tomatoes. Remove stems and cores, and slice or dice them as desired.
  3. In a large pot, combine your tomatoes with any desired seasonings, such as salt, sugar, or herbs. Cook them over medium heat until they are heated through, stirring occasionally.
  4. When your jars are finished boiling, remove them from the water and fill them with your hot tomato mixture using a canning funnel, leaving about 1/2-inch of headspace at the top of each jar.
  5. Clean the rims of the jars with a wet cloth, place lids on top, and screw on rings until they are only finger-tight.
  6. Process your jars in a boiling water bath for the recommended amount of time, usually 35-45 minutes, depending on the size of the jar and altitude.
  7. Remove jars from the water bath and let them cool on a towel for 24 hours. Check seals and store in a cool, dark place for up to a year.


Freezing is a fast and easy method of preserving tomatoes. Here’s how to freeze tomatoes:

  1. Blanch your tomatoes in boiling water for 30-60 seconds, then transfer them to a bowl of ice water to cool.
  2. Peel your tomatoes and remove any cores or blemishes.
  3. Place your tomatoes into freezer-safe bags or containers, removing as much air as possible. Label and store in the freezer for up to 6 months.


Drying is a method of preserving tomatoes that involves removing the moisture from them. This can be done in the sun, in a dehydrator, or in the oven. Here’s how to dry tomatoes using an oven:

  1. Preheat your oven to 200 degrees Fahrenheit.
  2. Cut your tomatoes in half and remove the cores.
  3. Place your tomatoes on a baking sheet lined with parchment paper, cut-side up.
  4. Sprinkle your tomatoes with salt and any desired seasonings, such as garlic or Italian herbs.
  5. Bake your tomatoes for 6-8 hours, until they are completely dehydrated but still pliable.
