With the benefits in mind, let’s dive into the methods of canning tomatoes without a pressure cooker.
Understanding the Basics of Canning
Canning is a method of preserving food in jars at high temperatures to kill bacteria, yeast, and molds. This process requires careful attention to ensure that your canned goods are safe to consume later.
Types of Canning Methods
There are two main canning methods you can use:
1. Water Bath Canning
Water bath canning is ideal for tomatoes. This method involves submerging jars in boiling water, which typically works well for high-acid foods like tomatoes. The acidic environment creates a barrier to harmful bacteria.
2. Pressure Canning
While pressure canning is the most common method for low-acid foods, it’s not necessary for tomatoes when using the water bath method. Nevertheless, if you do not have a pressure canner, water bath canning remains a reliable option.
Essential Supplies for Canning Tomatoes Without a Pressure Cooker
Before you begin the canning process, it’s essential to gather your supplies. Here’s what you’ll need:
- Fresh tomatoes: Choose ripe, firm varieties.
- Canning jars: Use clean, sterilized mason jars, typically pint or quart size.
- Jar lids and bands: Ensure good sealing.
- Large pot or canner: A deep pot to accommodate jars submerged in boiling water.
- Canning tools: Jar lifter, funnel, and ladle.
Preparing Your Tomatoes for Canning
Proper preparation is crucial for successful canning. Here’s how to prepare your tomatoes:
Choosing the Right Tomatoes
Select fresh, ripe tomatoes, free from blemishes or bruises. Varieties such as Roma or other paste tomatoes work best due to their lower moisture content, which means you’ll get thicker sauce and preserves.
Preparing the Tomatoes
Follow these steps to prepare your tomatoes for canning:
- Wash: Rinse tomatoes under cool running water.
- Blanch: Boil a separate pot of water. Submerge tomatoes for 30 seconds to 1 minute to loosen the skins.
- Peel: Once blanched, transfer tomatoes to ice water and peel them. The skins should slip off easily.
- Cut: Core and chop the tomatoes according to your preferred size.
Making Tomato Sauce for Canning
You can can whole tomatoes or make a tomato sauce. Here’s an easy recipe for a delicious tomato sauce.
Ingredients for Tomato Sauce
For every 20 pounds of tomatoes, you’ll need:
- 1 teaspoon salt (optional)
- 1 tablespoon lemon juice (to increase acidity)
- Aromatics (onions, garlic, herbs) – optional for flavor
Cooking the Sauce
- In a large pot, combine chopped tomatoes and any aromatics you are using.
- Cook on medium heat, stirring occasionally, for about 30 minutes until the tomatoes break down and release their juices.
- Pour in salt and lemon juice to enhance flavor and acidity.
- Remove from heat and let it cool slightly before ladling into jars.
Water Bath Canning Process
Now that your tomatoes are prepped and your sauce is ready, it’s time to get canning! Follow these steps for a successful water bath canning process.
Filling the Jars
- Sterilize Jars: Submerge your mason jars in boiling water for 10 minutes to sterilize.

- Wipe the Rim: Clean the rim of the jar with a clean cloth to ensure a proper seal.
- Seal the Jars: Place the lid on the jar and screw on the band until it’s fingertip-tight.
Processing the Jars
- Boil Water: Fill your canner or large pot with enough water that when the jars are added, they are covered by at least an inch of water.
- Place Jars in the Boil: Carefully lower the jars into the boiling water to prevent breakage.
- Process: Process the jars in boiling water for 35 to 45 minutes, depending on your altitude and jar size.
- Cool Down: Remove jars from the water using a jar lifter. Let them cool completely on a clean kitchen towel or rack without touching each other.
Storing and Enjoying Your Canned Tomatoes
Once cooled, check the seals by pressing down in the center of the lids; it should not pop back. If a jar didn’t seal, refrigerate it and use it within a few days.
Store your well-sealed jars in a cool, dark place to maximize their shelf-life. Properly canned tomatoes can last up to a year.
Tips for Optimal Tomato Canning
- Adjust for Altitude: If you live at higher altitudes, you may need to increase processing time.
- Lemon Juice is Crucial: Always add lemon juice or citric acid to low-acid foods to ensure safety.
- Label Your Jars: Date the jars for easy tracking of freshness.

What is the process for canning tomatoes without a pressure cooker?
To can tomatoes without a pressure cooker, you will need a boiling water bath method. Begin by selecting fresh, ripe tomatoes and washing them thoroughly. You should then prepare your jars by sterilizing them in boiling water for at least 10 minutes. Next, you can either peel the tomatoes by blanching them in boiling water for a few minutes or leave the skins on for flavor and texture.
Once the tomatoes are ready, pack them tightly into the sterilized jars. Add lemon juice or citric acid to each jar to ensure proper acidity levels, which is crucial for safe water bath canning. Fill the jars with hot water or tomato juice, leaving about half an inch of headspace, and then wipe the rims with a clean cloth to ensure a good seal. Secure the lids and process the jars in a boiling water bath for the recommended time based on your altitude and jar size.
Why is acidity important when canning tomatoes?
Acidity plays a vital role in the safety of canned tomatoes. The high acidity level helps prevent the growth of harmful bacteria, such as Clostridium botulinum, which can lead to botulism, a severe foodborne illness. For home canning, tomatoes are generally considered a low-acid food; therefore, adding an acidifying agent, such as lemon juice or citric acid, is crucial to lower the pH level.
The recommended amount of acid to add is about two tablespoons of lemon juice or one teaspoon of citric acid per quart of tomatoes. This ensures that the final product is safe for long-term storage. If you’re using a variety of tomatoes that are particularly low in acidity, you might need to adjust the quantity of your acidifying agent to make sure the overall pH remains below 4.6.
Can I use fresh herbs and spices when canning tomatoes?
Yes, you can use fresh herbs and spices to enhance the flavor of canned tomatoes, but it’s essential to add them in moderation. While herbs and spices can elevate the taste of the final product, adding too many ingredients can alter the acidity level required for safe canning. Stick to traditional flavorings like basil, oregano, and garlic, and use them sparingly to maintain safety.
When adding herbs or spices, it’s best to place them in the jar before filling it with tomatoes. You can also infuse the tomatoes with flavors by packing them with sprigs of herbs before processing. Just remember to keep track of your ingredient amounts and ensure that any additions do not compromise the acid levels required for safe preservation.
How long do I need to process canned tomatoes in a water bath?
The processing time for canned tomatoes in a boiling water bath usually ranges from 35 to 85 minutes, depending on the size of the jars and your altitude. For pint-sized jars, the general rule is around 35 to 45 minutes, while quart-sized jars require more time, typically 40 to 85 minutes. It’s essential to consult a reputable canning guide for specifics based on your local elevation and the size of the jar you are using.
To ensure safety, start your timer only after the water has reached a full rolling boil. If you live at a higher elevation, you may need to increase processing times further to account for lower boiling temperatures. After the time is up, allow the jars to cool on a counter, undisturbed, for 12-24 hours to create a proper seal before storing them.
What should I do if my jars don’t seal properly?
If your jars do not seal properly after canning, it’s important to address the issue before considering storage. First, check to ensure that the rims of the jars were clean before applying the lids; any residue can prevent a good seal. If you find that a jar hasn’t sealed, you can reprocess it by removing the lid, checking the rim for any debris, and then reapplying a new lid before placing it back in the boiling water for the recommended time.
Alternatively, if you prefer, you can refrigerate any unsealed jars and use their contents within a few days. Just remember that the shelf life is significantly shorter once you’ve opened a jar. It’s important to carefully monitor sealed jars for any signs of spoilage, such as off-smells or bulging lids, and discard them if necessary.
Can I freeze tomatoes instead of canning them?
Yes, freezing is a viable alternative to canning tomatoes and can often be simpler, especially if you’re new to preservation techniques. Freezing tomatoes retains their flavor and nutritional value, making it an excellent option for longer-term storage. You can freeze whole tomatoes, diced tomatoes, or even pureed tomatoes according to your preference, and it requires less detailed preparation compared to canning.
To freeze tomatoes, wash and core them, and you can choose to blanch them first if you prefer easier peeling. Pack the tomatoes into airtight freezer bags or containers, removing as much air as possible to prevent freezer burn. When you’re ready to use them, you can cook them directly from frozen or thaw them in the refrigerator overnight, making it a convenient option for adding to recipes year-round.
How do I know if my canned tomatoes are bad?
To determine if your canned tomatoes have gone bad, first, inspect the jars for visible signs of spoilage. This includes checking for bulging lids, leakage, or any off-putting odors when you open the lid. A properly sealed jar should have a lid that is level with the jar and doesn’t pop when pressed. If you notice any abnormalities in the jar or its contents, it’s best to err on the side of caution and discard it.
Another thing to monitor is the appearance of the tomatoes. If you see fuzz, discoloration, or an unusual film on the surface, these are indications that spoilage has occurred, and the contents should not be consumed. Always trust your senses—when in doubt, it’s safer to dispose of any suspicious-looking jars to avoid the risk of foodborne illness.
