Canning tomatoes is a fantastic way to preserve the fresh flavor of summer all year round. By using a pressure cooker, you can safely and efficiently can your own tomatoes at home. Not only does canning tomatoes allow you to enjoy their delicious taste whenever you want, but it also helps reduce food waste and saves you money in the long run.
Before you start canning tomatoes, it’s important to gather all the necessary equipment and ingredients. You will need a pressure cooker, canning jars with lids, a canning rack, a jar lifter, a lid lifter, a funnel, a ladle, a sharp knife, cutting board, and of course, fresh tomatoes. It’s recommended to use tomatoes that are ripe but still firm for the best results.
The first step in canning tomatoes is to wash your canning jars, lids, and bands in hot soapy water and then sanitize them by placing them in boiling water for a few minutes. While the jars and lids are boiling, you can start preparing your tomatoes. Wash them thoroughly and remove any stems or blemishes. You can choose to leave the tomatoes whole or cut them into halves or quarters, depending on your preference.
Once your jars and tomatoes are ready, it’s time to fill the jars. Place a funnel on top of a jar and carefully ladle the prepared tomatoes into the jar, leaving about 1/2 inch of headspace at the top. Be sure to remove any air bubbles by running a plastic utensil along the edges of the jar. Wipe the rim of the jar with a clean, damp cloth and place the lid and band on tightly.
Now it’s time to process the jars in the pressure cooker. Put the canning rack in the pressure cooker and add enough water to cover the jars by at least 1 inch. Close the pressure cooker and let it vent steam for 10 minutes. After that, place the weight on the vent pipe and turn the heat up to high. Once the pressure cooker reaches the appropriate pressure, lower the heat to maintain a steady pressure. Process the jars for the recommended time according to your altitude and the size of your jars.
After the processing time is up, turn off the heat and let the pressure cooker cool down naturally. Once the pressure has fully released, carefully remove the jars from the pressure cooker using a jar lifter and place them on a towel-lined countertop to cool. As the jars cool, you’ll hear the satisfying “ping” sound as the lids seal. Leave the jars undisturbed for 24 hours to ensure a proper seal.
Canned tomatoes can be stored in a cool, dark place for up to 1 year. When you’re ready to enjoy the taste of summer, simply open a jar of your homemade canned tomatoes and use them in your favorite recipes. Whether you’re making spaghetti sauce, salsa, or a delicious tomato soup, your canned tomatoes will add a burst of flavor to any dish.
With a pressure cooker and a few simple steps, you can easily can your own tomatoes and savor their fresh taste all year long. Don’t let your bountiful tomato harvest go to waste – start canning today!
The Benefits of Using a Pressure Cooker for Canning Tomatoes
Canning tomatoes using a pressure cooker offers several benefits that make it a popular choice among home cooks. Here are some reasons why you should consider using a pressure cooker for canning tomatoes:
1. Time-saving
A pressure cooker allows you to cook and preserve your tomatoes in a fraction of the time compared to traditional canning methods. The high heat and steam generated in the pressure cooker significantly speed up the cooking and sterilization process, reducing the overall cooking time.

Preparing the Tomatoes for Canning
Before you can start canning tomatoes using a pressure cooker, it’s important to properly prepare the tomatoes. This will ensure that you have high-quality and safe canned tomatoes to enjoy later on.
Start by selecting ripe and firm tomatoes. Avoid using overripe or damaged tomatoes, as they may affect the quality of the canned product.
Wash the tomatoes thoroughly under cold running water to remove any dirt or debris. Then, remove the stems and cores using a sharp knife.
Next, blanch the tomatoes to make them easier to peel. Bring a large pot of water to a boil and prepare a bowl of ice water. Carefully drop the tomatoes into the boiling water for about 30 seconds to 1 minute, or until the skins start to crack. Using a slotted spoon, transfer the tomatoes into the ice water to halt the cooking process and cool them down.
Once the tomatoes are cool enough to handle, peel off the skins. They should easily slide off, revealing the smooth and vibrant flesh underneath.
After peeling, you can choose to quarter, halve, or leave the tomatoes whole, depending on your preference. If the tomatoes are large, you may want to remove the seeds and excess liquid by gently squeezing them over a bowl or sink.
If you plan to can the tomatoes with their juice, set aside the liquid that collected during the squeezing process. This flavorful juice can be added to the canning jars later on.
Now that your tomatoes are prepared, you’re ready to move on to the canning process. Follow the instructions provided by your pressure cooker manufacturer for canning tomatoes, ensuring that you follow all safety guidelines to preserve the tomatoes properly.
Sterilizing Jars and Lids
Before you begin the canning process, it’s important to sterilize your jars and lids to ensure the preservation of your tomatoes. Sterilization kills bacteria and other microorganisms that can spoil your canned food.
Cleaning Jars and Lids
Start by washing your jars and lids with hot, soapy water. Rinse them thoroughly to remove any soap residue. Alternatively, you can run them through a dishwasher cycle using the hottest temperature setting. Make sure to handle the jars and lids with clean hands or clean utensils to prevent contamination.
Sterilizing Jars and Lids
There are two common methods for sterilizing jars and lids: boiling and using a pressure cooker.
If you choose to boil, place the jars and lids in a large pot filled with boiling water. Make sure they are completely submerged. Boil for at least 10 minutes to ensure proper sterilization. Remove the jars and lids using tongs and place them on a clean towel to air dry.
If you prefer to use a pressure cooker, add water to the cooker according to the manufacturer’s instructions. Place the jars and lids into the cooker, ensuring they are not touching each other or the sides of the cooker. Follow the pressure cooker’s guidelines for sterilization time and pressure.
Remember to always use new lids for each canning session, as used lids may not provide a proper seal.
| Method | Jar Size | Sterilization Time | Pressure |
|---|---|---|---|
| Boiling | Pints | 10 minutes | N/A |
| Pressure Cooker | Pints | 5 minutes | 10 PSI |
| Pressure Cooker | Quarts | 10 minutes | 10 PSI |
Once your jars and lids are sterilized, they are ready to be filled with your delicious canned tomatoes.
Processing and Sealing the Canned Tomatoes
Once you have prepared your tomatoes for canning and filled the jars with them, the next step is to process and seal the jars to ensure the tomatoes stay fresh and safe to consume. Follow these steps to properly process and seal your canned tomatoes using a pressure cooker.
