Making your own homemade pizza sauce is an immensely rewarding experience, allowing you to control the flavor and ingredients in a way store-bought sauces simply can't match. However, when it comes to preserving this sauce for later use, proper canning is essential to maintain freshness and safety. Using a pressure canner is the best method for canning homemade pizza sauce, especially since tomatoes, the key ingredient in pizza sauce, are a low-acid food. This actionable guide will walk you through the benefits of using a pressure canner, how to choose the best one for your needs, and provide a comprehensive, step-by-step process for canning homemade pizza sauce.
Tomatoes, the base for most pizza sauces, are technically a low-acid food. Low-acid foods are susceptible to bacterial growth, particularly Clostridium botulinum, which can cause botulism, a deadly form of food poisoning. In order to can pizza sauce safely, it's crucial to achieve the right internal temperature for an extended period to destroy harmful bacteria.
While tomatoes are commonly water-bath canned, it's important to note that pressure canning provides the high temperatures necessary to safely preserve pizza sauce for long-term storage. Pressure canning ensures the safety of your pizza sauce and preserves its rich flavor and thick consistency, so you can enjoy homemade pizza sauce any time of the year.
Choosing the right pressure canner is crucial for ensuring that your homemade pizza sauce is preserved safely and efficiently. Here are some key factors to consider before purchasing a canner:
The size of your canner will determine how many jars of pizza sauce you can process at once. If you plan on canning in large batches, a larger canner with more capacity is essential. However, if you only plan to can a small amount of sauce at a time, a smaller canner will suffice.
Pressure canners are typically made from either aluminum or stainless steel. The material of your canner impacts its durability, heat distribution, and ease of cleaning.
There are two common types of pressure control mechanisms: dial gauges and weighted gauges.
Pressure canning involves high-pressure environments, so having adequate safety features is crucial. Look for canners with:
A user-friendly pressure canner makes the canning process less intimidating, especially for first-time canners. Consider canners that are easy to clean, simple to operate, and come with clear instructions.

Once you've selected the right pressure canner, here's a detailed, step-by-step guide to canning your homemade pizza sauce:
Start by making your homemade pizza sauce. Typically, this involves cooking down fresh tomatoes (or using tomato paste), garlic, onions, herbs (like oregano and basil), and olive oil. Be sure to follow a tested recipe that accounts for acidifying the sauce to ensure safety.
If you're worried about acidity, you can add lemon juice or citric acid to each jar before sealing.
Sterilize your canning jars by washing them in hot, soapy water or running them through a dishwasher. Keep the jars hot until you're ready to fill them.
Using a ladle, fill your sterilized jars with hot pizza sauce, leaving about 1-inch headspace at the top. If desired, add 1 tablespoon of lemon juice or citric acid to each jar for added acidity.
Wipe the rims of the jars with a clean, damp cloth to remove any sauce residue. Place sterilized lids on the jars and screw on the metal bands, tightening them just until finger-tight.
Follow the instructions on your pressure canner for adding water and setting the correct pressure. Generally, you will need to process the jars at 10-15 pounds of pressure, depending on your altitude. For pint-sized jars, process for 35-40 minutes, and for quart-sized jars, process for 40-45 minutes.
Once the canning time is up, turn off the heat and let the canner cool down naturally. Once the pressure has dropped, carefully remove the jars and let them cool completely. Store the sealed jars in a cool, dark, and dry place for up to a year.
By using a pressure canner for your homemade pizza sauce, you can enjoy the fresh, vibrant flavors of your homemade sauce throughout the year. Not only does this preserve your hard work, but it also ensures that the sauce is safe to eat, free from harmful bacteria, and just as delicious as when it was first made. With the right canner and careful preparation, your homemade pizza sauce will be ready whenever you need it!
