Why Make Homemade Pizza Sauce for Canning?
Making your own pizza sauce offers several benefits over store-bought options:
Freshness and Flavor: Homemade pizza sauce can be made with high-quality, fresh ingredients, giving it a rich, full flavor that is unmatched by mass-produced sauces.
Customization: When you make your own sauce, you have control over the seasoning. You can adjust the level of heat, sweetness, or herbs to suit your personal taste.
Preservation: Canning allows you to preserve your pizza sauce for long periods, making it accessible when you need it, even in the off-season.
Cost-Effective: Making pizza sauce from scratch can be more affordable than purchasing pre-made sauces, especially if you have a garden full of ripe tomatoes.
No Additives or Preservatives: Homemade pizza sauce can be made without the additives, preservatives, and artificial flavors that are often found in store-bought versions.
Choosing the Right Tomatoes for Pizza Sauce
The foundation of any good pizza sauce is the tomato. The best tomatoes for making sauce are those that have a low water content and a rich, meaty texture. While many types of tomatoes can be used for canning pizza sauce, the following varieties are particularly well-suited for the task:
Roma Tomatoes (Plum Tomatoes): Roma tomatoes are the most popular choice for making pizza sauce. They are meaty, have fewer seeds, and have a rich, concentrated flavor that makes for a great sauce. Their firm flesh helps prevent the sauce from becoming too watery.
San Marzano Tomatoes: These tomatoes, grown in Italy, are prized for their balanced sweetness and acidity. They are often considered the best for making pizza sauce and are used by many pizza chefs around the world. They are also well-suited for canning due to their low moisture content.
Vine-Ripened Tomatoes: While vine-ripened tomatoes tend to be juicier than Roma or San Marzano tomatoes, they can still work well for pizza sauce. Be prepared to cook them down a bit longer to concentrate the flavor.
When choosing tomatoes for your pizza sauce, try to select tomatoes that are fully ripe but not overripe. Overripe tomatoes can lead to a sauce that is too sweet or watery, while underripe tomatoes might not provide the rich flavor you need.
Ingredients for Homemade Pizza Sauce
While the tomatoes form the base of the sauce, several other ingredients can elevate the flavor and give your pizza sauce a signature taste. Here is a list of the basic ingredients needed for homemade pizza sauce:
Olive Oil: Olive oil is commonly used to sauté the garlic and onions that form the flavor base of the sauce.
Garlic: Fresh garlic provides a rich, savory flavor that is essential for a good pizza sauce.
Onion (Optional): While not always used in pizza sauce, onions can add depth to the flavor profile.
Dried Oregano: Oregano is a classic herb used in pizza sauce. Its earthy, slightly bitter taste complements the sweetness of the tomatoes.
Basil: Fresh or dried basil adds a fragrant, aromatic note to the sauce.
Salt and Pepper: Simple seasoning like salt and freshly ground black pepper helps bring out the other flavors.
Sugar (Optional): If your tomatoes are particularly acidic, adding a small amount of sugar can balance the flavors and reduce the sharpness.
Red Pepper Flakes (Optional): For a bit of heat, red pepper flakes can be added to taste.
Tomato Paste (Optional): Tomato paste can be added to thicken the sauce and intensify the tomato flavor.
Lemon Juice or Citric Acid: When canning, adding acid is essential for safe preservation. This can be done by adding lemon juice or citric acid to your sauce before canning.
The Process of Making Homemade Pizza Sauce for Canning
Step 1: Preparing the Tomatoes
The first step in making pizza sauce for canning is to prepare the tomatoes. You’ll need to peel and core them to get the best texture for your sauce. Here’s how:
Blanch the Tomatoes: To remove the skins, bring a large pot of water to a boil. Score the bottoms of the tomatoes with an “X” using a knife. Place the tomatoes into the boiling water for 30-60 seconds, then transfer them immediately into an ice bath. The skins should peel off easily once the tomatoes are cooled.
Core the Tomatoes: Cut out the stem area of each tomato. If you are using Roma or San Marzano tomatoes, you can simply remove the core. For other tomatoes, slice them in half and remove any seeds and excess water from the center.
Chop the Tomatoes: Once peeled and cored, chop the tomatoes into smaller pieces to make the cooking process faster and easier.
Step 2: Cooking the Pizza Sauce
Now that your tomatoes are prepped, it’s time to cook them down into a rich, flavorful pizza sauce. Here’s how:
Sauté the Garlic and Onion: In a large saucepan or Dutch oven, heat about 2 tablespoons of olive oil over medium heat. Add finely minced garlic (about 3-4 cloves) and, if you like, finely chopped onion. Sauté the garlic and onion for 2-3 minutes, or until they are fragrant and softened.
Add the Tomatoes: Add the chopped tomatoes to the pan. Stir well to combine with the garlic and onion.
Season the Sauce: Add salt, pepper, dried oregano, and basil. If you’re using sugar to reduce acidity, add it now. If you like a bit of heat, add red pepper flakes to taste.
Simmer and Reduce: Bring the sauce to a simmer and let it cook for about 30-40 minutes. You want to cook the sauce down to a thick, paste-like consistency. Stir the sauce occasionally to prevent it from sticking to the bottom of the pan. If the sauce becomes too thick, you can add a little water or tomato juice to achieve your desired consistency.
Adjust the Seasoning: Taste the sauce and adjust the seasoning as needed. If the sauce tastes too acidic, you can add a little more sugar. If it’s too sweet, add a bit more salt or oregano.
Step 3: Preparing for Canning
Once your pizza sauce has cooked down to the desired consistency, it’s time to prepare it for canning. Proper canning procedures are essential to ensure that your sauce remains safe to eat and maintains its flavor.
Sterilize Jars: Before you begin canning, it’s important to sterilize your jars. Place your mason jars in a pot of boiling water for 10-15 minutes to kill any bacteria or germs. You can also sterilize the jars in the oven by placing them in a 250°F (120°C) oven for 10 minutes.
Prepare the Lids: Boil the lids in a small pot of water for a few minutes to ensure that the sealing compound on the lid softens properly.
Add Acid: To ensure your pizza sauce has enough acidity for safe canning, add lemon juice or citric acid to the sauce. For each pint jar, add 1 tablespoon of lemon juice or 1/4 teaspoon of citric acid.
Step 4: Canning the Pizza Sauce
Now that your jars and sauce are prepared, you can begin the canning process:
Fill the Jars: Using a ladle or funnel, carefully fill each sterilized jar with the pizza sauce, leaving about 1/2-inch of headspace at the top.
Remove Air Bubbles: Run a clean spatula or knife around the inside of the jar to remove any air bubbles. This helps prevent spoilage and ensures a good seal.
Seal the Jars: Wipe the rims of the jars with a clean cloth to remove any sauce residue. Place the lids on the jars and screw on the metal bands until they are fingertip-tight (not too tight).
Process the Jars: Place the jars in a boiling water canner or large pot filled with enough water to cover the jars by about an inch. Bring the water to a boil and process the jars for 35 minutes for pint-sized jars or 45 minutes for quart-sized jars. Start the timer once the water is at a full boil.
Cool and Check the Seals: After the processing time is complete, carefully remove the jars from the water and let them cool. As they cool, you should hear a popping sound as the lids seal. Once cooled, check the seals by pressing down on the center of each lid. If it doesn’t pop back, the jar is sealed properly.
Step 5: Storing Your Canned Pizza Sauce
Store your sealed jars in a cool, dark place, such as a pantry or basement. The sauce will keep for up to one year when properly sealed. Once you open a jar, store it in the refrigerator and use it within a week or two.
Conclusion

By following the steps outlined in this guide, you can create a flavorful, fresh pizza sauce that rivals anything you can buy in a store. With careful attention to preparation, cooking, and proper canning techniques, you’ll have jars of delicious pizza sauce ready to use whenever you’re craving homemade pizza.
