- 1 large onion, diced (optional)
- 1-2 cloves of garlic, minced (optional)
- Fresh herbs such as basil or oregano (optional)
- Salt to taste (1 teaspoon per quart is recommended)
Equipment
Gather the following canning equipment:
- A large pot for boiling water
- A smaller pot for preparing your stewed tomatoes

Step-by-Step Process for Canning Stewed Tomatoes
With your ingredients and equipment ready, let’s dive into the step-by-step process of making and canning stewed tomatoes.
Step 1: Preparing Your Tomatoes
The first step in canning stewed tomatoes is to prepare your tomatoes properly. To make removal of their skins easier, you’ll want to blanch them.
Blanching: Fill a large pot with water and bring it to a rapid boil. Carefully add the tomatoes for about 30 seconds to a minute. Using a slotted spoon, transfer them to an ice bath (a bowl of ice and cold water) to stop the cooking process. Once cooled, the skins will slip right off.
Cutting: After you’ve peeled your tomatoes, remove the cores and any blemishes. Cut them into quarters, or smaller pieces if you prefer a chunkier stew.
Cooking: In a separate pot, combine your peeled, chopped tomatoes with diced onion, minced garlic, and any herbs you want to use. Add salt to taste and cook over medium heat until the tomatoes soften and the juices start to meld, typically around 20-30 minutes.
Step 2: Sterilizing Your Jars
Before you start filling your jars, it’s crucial to sterilize them. This step prevents the growth of harmful bacteria and ensures a successful seal.
Wash Jars: Thoroughly wash your jars and lids in hot, soapy water.
Sterilize: Place the cleaned jars in a large pot of boiling water for about 10 minutes. Alternatively, you can run them through a cycle in the dishwasher on the hot setting.
Keep Hot: Once sterilized, keep the jars warm until you are ready to fill them to prevent cracking when they hit the hot contents.
Step 3: Filling the Jars
Now that you’re prepared, it’s time to fill your sterilized jars with delicious stewed tomatoes.
Ladle: Using a ladle, fill each jar with the stewed tomatoes, leaving about ½ inch of headspace at the top to allow for expansion during sealing.
Remove Air Bubbles: Take a clean knife or a bubble remover tool, and gently run it around the inside of the jar to remove any trapped air bubbles.
Wipe the Rim: Wipe the rims of the jars with a clean, damp paper towel to ensure no residue remains that could interfere with sealing.
Lid and Band: Place your sterilized flat lid on the jar and screw on the metal band until it’s fingertip tight. Do not overtighten, as this may prevent the creation of a proper vacuum seal.
Step 4: Processing the Jars
Processing the jars is essential for creating the vacuum seal that will keep your stewed tomatoes safe for long-term storage.
Boiling Water Bath: Place the filled and sealed jars into a large pot filled with boiling water. Make sure the jars are submerged in the water by at least an inch. If necessary, add more hot water to maintain this level.
Processing Time: Process your jars for approximately 40-45 minutes for quart jars and 30-35 minutes for pint jars. Adjust processing time if you are at higher altitudes.
Cooling: Once processed, use a jar lifter to remove the jars from the boiling water. Place them on a clean kitchen towel or a cooling rack to cool completely.
Tips for Successful Canning
To ensure your canning experience is successful and enjoyable, consider the following tips:
1. Choose the Right Tomatoes
Opt for fresh, ripe, high-quality tomatoes. Varieties such as Roma or San Marzano are excellent for stewing due to their meaty texture.
2. Maintain Cleanliness
Sanitation is critical in canning. Always work with clean hands, utensils, and surfaces to minimize the risk of contamination.
3. Monitor Seals
After cooling, check the seals by pressing the center of each lid. If it doesn’t pop back, the jar is sealed. If the lid can still be pushed down and popped back, refrigerate the jar and consume the contents within a few days.
4. Label and Store
Once your jars are sealed and cooled, label them with the date and contents before storing them in a cool, dark place. Consuming them within a year will ensure you enjoy the best flavor.
Conclusion
Canning stewed tomatoes without a pressure cooker is an approachable process that doesn’t require extensive equipment or expertise. By following this guide, you’re not only preserving the flavors of summer but also creating a base for countless meals throughout the year. Whether you’re adding them to pasta, soups, or pizzas, your home-canned stewed tomatoes will bring a taste of home that’s hard to beat.

What ingredients do I need to can stewed tomatoes without a pressure cooker?
To can stewed tomatoes without a pressure cooker, you’ll need fresh, ripe tomatoes, which are the star ingredient. Aim for varieties such as Roma or beefsteak, as they have a high flesh-to-juice ratio. Additionally, gather other ingredients like onions, garlic, bell peppers, and herbs such as basil or oregano to enhance the flavor of your stewed tomatoes. Don’t forget to have salt and lemon juice or citric acid on hand to ensure proper acidity for safe canning.
You will also need canning jars, lids, and rings specifically designed for canning to ensure a good seal. Make sure that your jars are clean and sterilized before use.

Is it safe to can stewed tomatoes without a pressure cooker?
Yes, it is safe to can stewed tomatoes without a pressure cooker, as long as you follow the guidelines for water bath canning. Tomatoes are considered low-acid foods, but by adding lemon juice or citric acid to the jars, you can safely increase their acidity. This added acidity helps to prevent the growth of botulism in the sealed jars, which is a crucial aspect of food safety during the canning process.
Ensure that you follow recommended guidelines, including processing times at the right temperature. Always refer to trusted sources, such as the USDA or extension service publications, for specific instructions on proper canning methods. This way, you can enjoy your homemade stewed tomatoes without any safety concerns.
How long should I process stewed tomatoes in a water bath?
The processing time for stewed tomatoes in a water bath typically ranges from 35 to 45 minutes, depending on the jar size. For pint-sized jars, a processing time of about 35 minutes is generally recommended, while quart-sized jars should be processed for around 45 minutes. Adjustments may be necessary based on your altitude, so consulting a canning guide for your specific region is advisable.
Remember that once the water reaches a rolling boil, you start your timer for processing. After processing, allow the jars to cool slowly at room temperature. Once filled and sealed correctly, the jars should last for one to two years in proper storage conditions, although they can be enjoyed much sooner!
Can I add other vegetables or spices to my stewed tomatoes?
Absolutely! Adding other vegetables like zucchini, corn, carrots, or celery can enhance the flavor and texture of your stewed tomatoes. Many home canners customize their recipes by integrating spices such as bay leaves, thyme, or red pepper flakes to give their stewed tomatoes a unique twist. However, it is essential to maintain the balance of acidity and not over-fill the jars to ensure proper sealing and safe preservation.
When experimenting with additional ingredients, keep in mind that they shouldn’t compromise the overall tomato volume in the jar. If you plan on increasing the number of vegetables or spices, make sure to record the amounts you use for future reference. For safety, refer to reliable canning resources to ensure that the alterations do not affect the safe processing times.
What is the best way to store canned stewed tomatoes?
Once your stewed tomatoes are properly canned and cooled, store them in a cool, dark place, such as a pantry or cupboard. The ideal storage temperature for home-canned goods is between 50°F and 70°F. Make sure that the jars are placed away from direct sunlight, which can degrade the quality of the contents over time.
Also, keep an eye on the seal of the jars; if you notice any signs of spoilage, such as bulging lids or leaks, it’s best to discard them. Properly stored, your canned stewed tomatoes can remain safe to eat for one to two years, although they are often best consumed within the first year for optimal flavor.
How can I tell if my canned stewed tomatoes have gone bad?
Signs that canned stewed tomatoes have gone bad include a bulging lid, a broken seal, or any leakage from the jar. If you notice that the contents have discolored or developed an off smell once opened, it’s best to err on the side of caution and discard the jar. Additionally, if you see any signs of mold or unusual growth along the lid or inside the jar, it’s not safe to consume.
Moreover, when you open a jar, look at the consistency and taste a small amount. If anything seems off, don’t take any risks with your health. Home canning can be safe and rewarding, but vigilance in assessing the condition of your canned goods is essential for good practice and food safety.
Can I use the same method to can diced tomatoes?
Yes, you can use a similar method to can diced tomatoes, as the water bath canning technique applies to various forms of tomatoes, including diced or crushed. Ensure that you maintain the proper acidity level by adding lemon juice or citric acid. The key is to ensure your diced tomatoes are ripe and well-prepared, cutting them to the desired size before placing them in clean, sterilized jars.
Keep in mind that processing times may vary slightly based on the size of the diced tomatoes and the overall density of the jar. As with stewed tomatoes, follow reputable canning guidelines to ensure safety and quality. This method allows you to enjoy a vibrant tomato flavor in your dishes any time of the year!
What should I do if my canned tomatoes didn’t seal properly?
If your canned tomatoes didn’t seal properly, don’t despair; there are a few options you can consider. First, inspect the jar and lid for any cracks or damage. If the problem is just with the lid, you might be able to re-process the jar. Remove the lid, check the rim of the jar for any residue, and then clean it carefully before using a new lid and processing the jar again for the recommended time.
If reprocessing is not an option or the seal remains unsealed after a second attempt, it’s best to refrigerate the contents and use them within a few days. You could also consider freezing the tomatoes for later use, preserving their quality for months. Always prioritize safety, and never consume unsealed jars that have been left at room temperature.
