When summer’s bounty of juicy, ripe tomatoes starts to dwindle, preserving those beautiful flavors can feel like a race against time. Whether you’ve grown your own tomatoes or sourced them from local farmers, there comes a moment when you need to make a decision: can you can sauce made from frozen tomatoes? The answer is not only a resounding yes, but it also opens a treasure trove of culinary possibilities! In this comprehensive guide, we’ll explore the ins and outs of canning with frozen tomatoes, the best methods to ensure flavor retention, and some tempting sauce recipes that will keep your pantry stocked for the chilly months ahead.
Understanding the Canning Process with Frozen Tomatoes
Before diving into the specifics, it’s essential to understand the basics of both freezing and canning tomatoes.
Why Freeze Tomatoes?
Freezing tomatoes is an excellent way to extend their shelf life without compromising the flavor or texture significantly. Here are a few key points to keep in mind:
- Preservation: Freezing halts the action of enzymes that can lead to spoilage.
- Convenience: You can harvest and freeze tomatoes at their peak ripeness and quality, ensuring you have the best produce for canning later.
- Variety: Different varieties of tomatoes can be frozen and used based on your sauce preferences.
Preparing Your Frozen Tomatoes for Canning
Once you’re ready to turn those frozen tomatoes into succulent sauce, proper preparation is vital. Here’s how to get started:
-
Thaw the Tomatoes: Allow the frozen tomatoes to thaw in the fridge overnight or in a bowl placed under running cold water. Avoid microwave thawing, as this can alter the texture.
-
Remove Skins (Optional): If you prefer a smoother sauce, blanched skins can be removed. Although frozen tomatoes often have thinner skins that are easier to slip off, some prefer to leave them on for added texture.
-
Chop and Puree: Depending on your desired sauce consistency, chop or puree the thawed tomatoes.
Canning Basics You Need to Know
Canning may seem intimidating, but with the right tools and techniques, you can safely preserve your homemade sauce.
Essential Tools for Canning
Before you get started, gather the necessary equipment:
- Canning Jars: Use glass jars that are specifically made for canning, such as Mason jars.

Safety First: The Importance of Acidity
Tomatoes can vary in acidity based on their variety and ripeness. Higher acidity levels are crucial for safe canning to prevent the growth of Clostridium botulinum, which can lead to botulism. To ensure safety:
- Consider adding lemon juice or citric acid to your sauce. Generally, you should add about 1 tablespoon of lemon juice per quart of sauce.
- Skim off any visible foam during the cooking process to achieve a clearer sauce.
Steps to Can Sauce from Frozen Tomatoes
Now that you’re prepared, here’s a detailed step-by-step guide to canning sauce from those frozen tomatoes.
Step 1: Cook Your Sauce
-
Simmer the Sauce: In a large pot, combine your prepared tomatoes with additional ingredients like onions, garlic, herbs, and spices. Bring the mixture to a simmer, allowing the flavors to meld.
-
Reduce the Mixture: Cook until the sauce reaches your desired consistency. A thicker sauce generally takes longer to make, but you won’t have to worry about it breaking down during the canning process.
Step 2: Fill the Jars
-
Prepare Jars: Sterilize your canning jars in boiling water for about 10 minutes. Keep them warm until you’re ready to fill them.
-
Pour the Sauce: Using a ladle and funnel, fill the jars with hot sauce, leaving about 1/2-inch headspace at the top.
Step 3: Seal and Process
-
Wipe the rims: Ensure that the rims of your jars are clean to ensure a proper seal.
-
Apply Lids and Bands: Place the lids on the jars and screw on the bands until they’re fingertip-tight.
-
Process in a Water Bath: Place the jars in the water bath canner, making sure they are submerged by at least an inch of water. Bring the water to a rolling boil and process for 35-40 minutes based on your altitude.
Step 4: Cool and Store**
After processing, remove the jars and place them on a clean dish towel or rack to cool completely. You should hear a popping sound as the lids seal. Once cool, check the seals by pressing the center of each lid. If it doesn’t pop back, the jar has sealed properly. Label and date your jars, and store them in a cool, dark place.

Can you can sauce made from frozen tomatoes?
Yes, you can can sauce that is made using frozen tomatoes! That being said, it’s essential to understand that freezing changes the texture of tomatoes, which can impact the final sauce’s quality. When you thaw frozen tomatoes, they tend to become mushy and release a lot of liquid. This means you’ll need to create a thicker sauce and control the consistency carefully to achieve desired results during the canning process.
Moreover, while some might worry that the freezing process compromises the safety of the tomatoes for canning, it doesn’t inherently pose a risk. Just ensure you follow safe canning practices, such as using pressure canning for low-acid foods. Additionally, maintaining proper acidity levels in your sauce is crucial for safe preservation, so consider adding lemon juice or vinegar if necessary.
What are the best types of tomatoes for making sauce?
When making sauce, especially for canning purposes, Roma tomatoes are often cited as the best choice. They are known for their meaty texture, lower moisture content, and rich flavor, which all contribute to a thicker, more concentrated sauce. Other varieties, such as San Marzano or Amish Paste tomatoes, are also excellent for making sauces because they provide an intense flavor and hold up well during cooking.
However, you can certainly utilize a mix of different tomato varieties, depending on what you have available, including any frozen tomatoes you might be using. Mixing tomatoes can enhance the depth of flavor in your sauce, although it’s advisable to avoid overly watery types like beefsteak tomatoes if you want to maintain a thicker, more sauce-like consistency.
How should I prepare frozen tomatoes for canning?
Preparing frozen tomatoes for canning involves a few steps to ensure that you achieve the best flavor and texture. First, you’ll need to thaw the tomatoes either in the refrigerator or by placing them in a pot of warm water. Once they are thawed, you can easily remove the skins by blanching them briefly in hot water or by simply squeezing them out. This step improves the sauce’s texture and allows for a smoother finish.
After peeling the tomatoes, chop them up, and don’t forget to strain out some of the excess liquid if you want a thicker sauce. Depending on your recipe, you may wish to cook the tomatoes down along with seasonings, onions, or garlic to create your desired flavor profile. Make sure your workspace and utensils are sanitized, and when you are ready to can the sauce, it’s vital to follow the guidelines provided by the National Center for Home Food Preservation or similar organizations to ensure safety.
Is it necessary to add any preservatives when canning sauce from frozen tomatoes?
When canning sauce from frozen tomatoes, it is not strictly necessary to add commercial preservatives.
