How Long Will Canned Tomatoes Last?

These will last for 1-2 years. That is the beauty of canning! Being able to preserve food for an extended amount of time! If for some reason the seal is broken or compromised at any time during the canning process or after, discard it immediately. You do not want to risk getting sick from the bacteria that can grow if the seal is broken and contaminated. Use in any recipe that calls for canned tomatoes such as chili, tacos, marinara, pasta, etc.

How to Can Tomatoes [without a pressure cooker]

Description

Canning can be an intimidating process, but I am here to show you just how easy it is to can summer fresh tomatoes without a pressure cooker! Anyone can do it and you'll enjoy summer tomatoes all year round!

Ingredients

Scale

10 Pounds Ripe Tomatoes
5 Teaspoons Salt

Equipment Needed

Large stock pot*
10 wide mouth pint* or 5 quart Mason jars
10 new wide mouth Mason jar lids and seals* or 5 regular lids and seals*
Canning funnel*
Large deep soup spoon*
Towels

Instructions

Wash and dry your tomatoes. Add a large stockpot to the stove over medium heat. Quarter or largely dice the tomatoes and add to the pot. Stir and bring to a shimmer.
Place a lid on and let cook for 3-4 hours. The tomatoes will cook down during that time.
While the tomatoes are cooking, prep your jars. Place each mason jar in the dishwasher and run on a hot sanitizing cycle. Wash and dry the new rings and seal with hot soapy water. NOTE - the mason jars need to be hot when ready to fill with tomatoes. Adding the hot tomatoes to a cold mason jar glass will result in the jar breaking.
Once the tomatoes are finished and the jars are clean, place a canning funnel into the jar and slowly fill the jars with the cooked tomatoes to right under the start of the seal - making sure not to get anything on the rim of the jar! Do not fill all the way to the top. There needs to be room left in the jar.
Continue filling until the tomatoes are all used. This will get you approximately 5-quart jars or 10-pint jars full.
To each jar place 1/2 teaspoon of salt per PINT jar or 1 teaspoon salt per QUART in each jar. Again make sure not to get any salt or anything on the rim of the jar.
Wipe the rims of the jars if any tomatoes are salt have gotten on the seal and rim with a clean dry paper towel.
Once the salt is in, place the new lids and seals on and close tightly.
Lay a beach towel (or a large towel) on the kitchen counter. Place each jar upside down on the towels and then place another towel on top. Leave wrapped in the towels on the counter overnight or for 24 hours to slowly cool.
Once they have cooled completely, double-check that they have completely sealed by placing your finger on top and checking for the top to not “pop”. Once sealed, store in the pantry.
Use in any recipe that calls for canned tomatoes.

Canned tomatoes will last for 1-2 years stored in a cool dry dark place like your pantry
Use in any recipe that calls for canned tomatoes
If the top "pops" after the cans have cooled (meaning, if you press down on the lid with your finger and there is a give), the cans have not sealed properly. Discard immediately and do not use. There was likely something on the rim preventing from getting a complete and tight seal.
