When it comes to canning diced tomatoes with a pressure cooker, it’s important to choose the right tomatoes for the best results. Here are some factors to consider when selecting your tomatoes:
– Variety: Look for tomatoes that are meaty and have a lower water content. Plum tomatoes, such as Roma or San Marzano, are often preferred for canning because they have a dense flesh and fewer seeds.
– Ripeness: Choose tomatoes that are fully ripe but not overripe. They should be firm enough to hold their shape when cut into cubes.
– Size: Opt for tomatoes that are medium to large in size. Smaller tomatoes can be used, but they will require more effort to peel and dice.
– Quality: Inspect the tomatoes for any signs of damage, mold, or decay. Choose tomatoes that are blemish-free and have a vibrant color.
– Organic or locally grown: If possible, opt for organic or locally grown tomatoes. They are often fresher and have a better taste.
By choosing the right tomatoes, you can ensure that your canned diced tomatoes will have a delicious taste and a good texture.

Preparing the tomatoes
Before you can start canning diced tomatoes with a pressure cooker, you need to properly prepare the tomatoes. Follow these steps:
1. Selecting the tomatoes
Choose ripe and firm tomatoes for canning. Avoid tomatoes that are overripe or have soft spots, as they may affect the quality of the canned tomatoes.
2. Washing the tomatoes
Thoroughly wash the tomatoes under running water to remove any dirt or debris. Use a soft brush or your hands to gently scrub the tomatoes.
3. Peeling the tomatoes
To facilitate the peeling process, blanch the tomatoes in boiling water for about 30-60 seconds, or until you notice the skin starting to loosen. Then, transfer the tomatoes to a bowl of ice water to cool down quickly. The quick temperature change will help to easily remove the tomato skins.
4. Removing the core and seeds
Once the tomatoes are peeled, cut out the cores using a sharp knife and remove any seeds or excess juice. This step is optional, as some people prefer to keep the seeds and juice in their canned tomatoes.
5. Dicing the tomatoes
Place the peeled and prepared tomatoes on a clean cutting board and dice them into smaller pieces. Ensure that the size of the diced tomatoes is consistent for even cooking and canning.
Note: It is recommended to work in small batches while dicing the tomatoes to prevent them from getting too juicy or mushy.
Now that you have properly prepared the tomatoes, you are ready to proceed with the canning process using your pressure cooker.
Cooking the tomatoes in a pressure cooker
Using a pressure cooker to can diced tomatoes is a great way to efficiently preserve your fresh produce. The high heat and pressure in the cooker help to retain the flavors and nutrients of the tomatoes while ensuring the jars are properly sealed for long-term storage.
Step 1: Prepare the tomatoes
Start by washing the tomatoes thoroughly and removing any stems or blemishes. You can choose to keep the skins on or peel them off, depending on your preference. Once the tomatoes are prepped, chop them into evenly sized pieces.
Step 2: Preparing the pressure cooker
Before cooking the tomatoes, it’s essential to prepare your pressure cooker. Ensure that the rubber gasket on the lid is in good condition and fits snugly. You should also check the pressure release valve and make sure it is clean and unobstructed.
Step 3: Fill the jars
Next, sterilize your canning jars and lids by placing them in boiling water for a few minutes. Once sterilized, fill the jars with the diced tomatoes, leaving about 1 inch of headspace at the top. Add any desired seasonings, such as salt, pepper, or herbs, to the jars.

Step 4: Pressure cooking the tomatoes
Place the filled jars in the pressure cooker, ensuring they are not touching each other or the sides of the cooker. Add water to the cooker according to the manufacturer’s instructions, usually about 2-3 inches deep.
Secure the lid on the pressure cooker and turn on the heat. Allow the cooker to come up to full pressure, usually indicated by the cooker’s pressure gauge or indicator. Once at full pressure, reduce the heat to maintain a steady pressure and start the timer according to your recipe’s instructions.
Step 5: Cooling and storing
Once the timer is up, turn off the heat and allow the pressure to release naturally. Do not force the pressure release by opening the valve. Once the pressure has fully released, carefully remove the jars from the pressure cooker.
Place the jars on a towel or cooling rack and allow them to cool undisturbed for at least 12 hours. Check that the lids have sealed by pressing down on the center. If the lids do not flex, they are properly sealed.
Label the jars with the date and store them in a cool, dark place, such as a pantry or cellar. The canned diced tomatoes can be stored for up to 1 year.

Sealing the jars
Once your diced tomatoes and canning jars are ready, it’s time to seal the jars to ensure their contents remain fresh and safe for consumption. Here’s a step-by-step guide on how to seal the jars using a pressure cooker:
Step 1: Prepare the lids and bands
Before sealing the jars, make sure the lids and bands are clean and in good condition. Wash them with hot, soapy water and rinse thoroughly. Inspect the lids for any dents or damage, and discard any that are compromised. The bands should be free from rust or corrosion.
Step 2: Fill the jars with diced tomatoes
Using a canning funnel, carefully ladle the diced tomatoes into the prepared jars, leaving about half an inch of headspace at the top. Wipe the rim of each jar with a clean, damp cloth to remove any spills or food particles that could prevent a proper seal.
Step 3: Apply the lids and bands
Place a lid on top of each jar, ensuring that the sealing compound on the lid comes into contact with the jar rim. Secure the lids in place by screwing on the bands until they are finger-tight. Avoid overtightening the bands, as this can interfere with the sealing process.
Step 4: Load the jars into the pressure cooker
Following the manufacturer’s instructions, place the jars inside the pressure cooker, ensuring they are arranged in a way that allows steam to circulate around them. Make sure the pressure cooker’s rack is in position to prevent the jars from touching the bottom of the cooker.
Step 5: Process the jars in the pressure cooker
Close the pressure cooker lid securely and follow the instructions for processing the jars at the recommended pressure and time. This will vary depending on your altitude and the specific pressure cooker you are using. Monitor the pressure gauge or indicator throughout the processing time to ensure proper pressure is maintained.
Step 6: Allow the pressure cooker to cool and release pressure
Once the processing time is complete, allow the pressure cooker to cool naturally and release pressure according to the manufacturer’s instructions. Avoid opening the pressure cooker prematurely, as this can affect the sealing process.
Step 7: Check the seal
After the pressure cooker has fully cooled and depressurized, carefully remove the jars from the cooker and check the seal. Gently press on the center of each lid to ensure it is concave and does not move or make a clicking sound. Any lids that do not pass this test have not sealed properly and should be refrigerated and consumed soon or reprocessed using a new lid.
Following these steps will ensure that your diced tomatoes are properly sealed and ready to be stored in your pantry for future use. Enjoy the convenience and taste of home-canned tomatoes all year round!
