Tomatoes are one of the most popular garden fruits (yes, they’re technically a fruit!) to can at home, and for good reason. They’re versatile, nutritious, and can be preserved in a variety of ways to enjoy throughout the year. However, one question that often arises among home canners is whether it’s safe and acceptable to can tomatoes with their skins on. In this article, we’ll delve into the world of home canning, exploring the pros and cons of canning tomatoes with skins on, and providing you with the knowledge and confidence to make informed decisions in the kitchen.
Understanding the Basics of Home Canning
Before we dive into the specifics of canning tomatoes with skins on, it’s essential to understand the basics of home canning. Home canning is a simple and effective way to preserve food, but it requires attention to detail and adherence to safe canning practices to avoid spoilage and foodborne illness.
Home canning involves packing food into clean, sterilized jars, adding a brine or syrup, and then heating the jars to kill off any bacteria or other microorganisms that may be present. The jars are then sealed and allowed to cool, creating a vacuum seal that prevents new contaminants from entering the jar.
The Importance of Acidic Foods in Home Canning
Tomatoes are a high-acid food, which makes them ideal for home canning. Acidic foods, such as fruits and pickled vegetables, are naturally more resistant to spoilage and can be canned using a water bath canner. Low-acid foods, such as meats and green beans, require a pressure canner to ensure that they’re heated to a high enough temperature to kill off any bacteria.
Why Acidic Foods Are Easier to Can
Acidic foods are easier to can because they’re less susceptible to spoilage. The acidity of the food creates an environment that’s unfavorable to the growth of bacteria and other microorganisms. This means that acidic foods can be canned at a lower temperature, using a water bath canner, without the risk of spoilage.
The Pros and Cons of Canning Tomatoes with Skins On
Now that we’ve covered the basics of home canning, let’s explore the pros and cons of canning tomatoes with skins on.
The Pros of Canning Tomatoes with Skins On
There are several advantages to canning tomatoes with skins on:
- Convenience: Leaving the skins on can save time and effort in the kitchen. You won’t need to blanch and peel the tomatoes before canning them.
- Nutrition: Tomato skins are rich in fiber, vitamins, and minerals, including lycopene, an antioxidant that’s been linked to several health benefits.
- Flavor: Some canners swear that leaving the skins on adds depth and complexity to the flavor of the tomatoes.
The Cons of Canning Tomatoes with Skins On
While there are some advantages to canning tomatoes with skins on, there are also some potential drawbacks to consider:

Addressing Food Safety Concerns
While there’s a risk that the skins may not be heated evenly during the canning process, this can be mitigated by following safe canning practices. It’s essential to ensure that the tomatoes are packed tightly into the jars, leaving enough headspace for the brine or syrup. The jars should then be heated to a rolling boil for at least 20 minutes to ensure that the tomatoes are heated evenly and that any bacteria or other microorganisms are killed off.
Best Practices for Canning Tomatoes with Skins On
If you’ve decided to can tomatoes with skins on, here are some best practices to follow:
- Choose the Right Tomatoes: Look for tomatoes that are high in acidity, such as Roma or plum tomatoes. These varieties will be more resistant to spoilage and will hold their shape better during the canning process.
- Prepare the Tomatoes: Wash the tomatoes thoroughly, and then chop or crush them to release their natural juices.
- Pack the Tomatoes: Pack the tomatoes tightly into clean, sterilized jars, leaving enough headspace for the brine or syrup.
- Add the Brine or Syrup: Add a brine or syrup to the jars, making sure to leave enough headspace.
- Seal the Jars: Seal the jars and process them in a boiling water bath for at least 20 minutes.
Alternative Methods for Canning Tomatoes
If you’re concerned about the potential drawbacks of canning tomatoes with skins on, there are alternative methods you can use:
- Blanching and Peeling: Blanch the tomatoes in boiling water for 10-15 seconds, and then peel them before canning.
- Using a Pressure Canner: Use a pressure canner to can the tomatoes, which will ensure that they’re heated to a high enough temperature to kill off any bacteria.
Conclusion
Canning tomatoes with skins on can be a convenient and nutritious way to preserve this delicious fruit.
