Pizza sauce is the heart and soul of any delicious homemade pizza. The tangy flavors of tomatoes, herbs, and spices meld together to create a symphony of taste that can elevate your pizza game to the next level. More importantly, making your own pizza sauce allows you to control the ingredients, ensuring a fresh and flavorful experience every time. If you’re looking to take your pizza sauce to the next level, consider canning it in a pressure cooker. This method not only preserves the flavor but also extends the shelf life of your sauce. In this comprehensive guide, we’ll cover everything you need to know about how to can pizza sauce in a pressure cooker.
Understanding the Pressure Canning Process
Before diving into the step-by-step process of canning pizza sauce, it is crucial to understand the basics of pressure canning. Canning is a method used to preserve food by sealing it in jars while heating it to high temperatures, killing bacteria, yeasts, and molds that could spoil the food. Pressure canning is essential for low-acid foods like veggies and some sauces that need higher temperatures to achieve proper preservation.
Why Use a Pressure Cooker for Canning Pizza Sauce?
Using a pressure cooker for canning has several advantages that make it an appealing option:
- Efficiency: Pressure cookers can reach higher temperatures faster than water bath canning, reducing processing time.
- Safety: The high-pressure environment ensures that the food is canned safely, minimizing the risk of botulism, a dangerous bacteria that can grow in improperly canned low-acid foods.
Gathering Your Ingredients and Supplies
To get started, you’ll need a few key ingredients and supplies. Here’s a comprehensive list:
Ingredients
- Fresh tomatoes (about 20-25 medium-sized)
- 1 can (6 ounces) of tomato paste (optional, for thickness)
- 2 tablespoons olive oil
- 4 cloves garlic, minced
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1 teaspoon salt (adjust to taste)
- 1/2 teaspoon black pepper
- 1/2 teaspoon sugar (optional)
- 2 tablespoons lemon juice (to ensure acidity)
Essential Supplies
- Pressure cooker (make sure it is rated for canning)

Preparing Your Pizza Sauce
The first step in canning pizza sauce is to make the sauce itself. Follow this easy recipe to prepare your mixture before canning.
Step-by-Step Pizza Sauce Recipe
- Prepare the Tomatoes: Start by washing the tomatoes thoroughly. Core and chop them into quarters.
- Cook the Sauce: In a large pot over medium heat, add the olive oil. Sauté the minced garlic until fragrant, then add the chopped tomatoes. Stir to combine and let the mixture simmer for about 20–30 minutes. This allows the flavors to meld and the tomatoes to break down.
- Blend the Sauce: For a smoother consistency, use an immersion blender to puree the sauce. Alternatively, transfer the mixture to a blender and blend until smooth.
- Add Remaining Ingredients: Return the sauce to the pot and stir in the tomato paste (if using), oregano, basil, salt, pepper, sugar, and lemon juice. Simmer for another 10–15 minutes until the sauce reaches your desired thickness.
Canning Your Pizza Sauce
Now that your pizza sauce is ready, it’s time to can it. This process will ensure that your sauce is preserved for future use.
Step-by-Step Canning Process
Prepare the Pressure Cooker: Fill your pressure cooker with water according to the manufacturer’s instructions. Set it on the stove and bring it to a gentle simmer while you prepare your jars.

Seal the Jars: Place the sterilized lids on top of each jar and screw on the rings until they are fingertip-tight. Don’t over-tighten, as air needs to escape during the canning process.
Load the Pressure Cooker: Once all the jars are filled and sealed, carefully place them in the pressure cooker, ensuring that they do not touch each other or the sides of the pot.
Process the Jars: Secure the lid on the pressure cooker and increase the heat to achieve the appropriate pressure (usually 10-15 psi, but consult your pressure cooker’s manual). Process pint jars for 25 minutes and quart jars for 35 minutes.
Cool Down: Turn off the heat and allow the pressure cooker to cool down naturally. Do not attempt to open the lid until the pressure has fully released.
Check Seals: After the jars have cooled for about 12-24 hours, check the seals. The lids should not flex when pressed. Store any jars that have not sealed properly in the refrigerator and use them within a week.
Storing Your Canned Pizza Sauce
Proper storage is vital to ensure that your pizza sauce remains safe and delicious. Here are some tips for storing your canned sauce:
Optimal Storage Practices
- Store the canned jars in a cool, dark, and dry place, such as a pantry or cupboard.
- Keep track of the date you canned your sauce. Most home-canned sauces remain safe for up to a year, while the flavor and quality are best within the first six months.
- For long-term storage, consider vacuum-sealing the jars or using mylar bags if you have additional leftovers.
Cooking with Your Canned Pizza Sauce
One of the joys of canning pizza sauce is that you can enjoy delicious, homemade pizza all year round. Here are a few ideas on how to incorporate your canned pizza sauce into various dishes:
Recipe Ideas
- Classic Homemade Pizza: Use your sauce as a base for a classic margherita pizza topped with fresh mozzarella and basil.
- Pasta Sauce: Use the pizza sauce as a quick pasta sauce. Add cooked pasta, sautéed vegetables, and a sprinkle of parmesan for a hearty meal.
- Dipping Sauce: Warm the sauce and enjoy it as a dip for breadsticks or mozzarella sticks.

What is the best type of tomatoes to use for pizza sauce when canning?
The best type of tomatoes for pizza sauce are paste tomatoes, such as Roma or San Marzano varieties. These tomatoes have a lower water content, which results in a thicker and more concentrated sauce, perfect for pizza. Their rich flavor profile enhances the overall taste of the sauce, making it ideal for canning.
Additionally, you can mix in other varieties if you prefer a more complex flavor. Combining different types of tomatoes can lead to a more balanced sauce. Just make sure to maintain a high percentage of paste tomatoes to achieve the desired consistency.
Do I need to add acid to my pizza sauce before canning?
Yes, it is important to add acid to your pizza sauce before canning. Acid helps to ensure the safety of the canned food by preventing the growth of bacteria, particularly botulism. You can add lemon juice or vinegar as a source of acid, and the recommended amount is 1 tablespoon of lemon juice or 1 teaspoon of citric acid per quart of sauce.
Incorporating this step not only enhances safety but can also improve the flavor of your sauce. Just make sure to measure the acid precisely and mix it thoroughly into your sauce to ensure uniform distribution.
