Canning collard greens is a great way to preserve this nutritious leafy green vegetable for future meals. While many recipes call for a pressure cooker, it’s entirely possible to can collard greens without one. In this article, we’ll explore the steps and techniques involved in canning collard greens without a pressure cooker.
Understanding the Basics of Canning
Before we dive into the specifics of canning collard greens, it’s essential to understand the basics of canning. Canning is a method of preserving food by packing it in airtight containers and heating them to kill off any bacteria or other microorganisms that may be present. This process creates a vacuum seal that prevents new contaminants from entering the container.
There are two main types of canning: water bath canning and pressure canning. Water bath canning is suitable for high-acid foods like fruits, pickles, and jams, while pressure canning is necessary for low-acid foods like meats, poultry, and vegetables. Collard greens are a low-acid food, which means they require pressure canning to ensure they’re safe to eat. However, as we’ll discuss later, there are ways to can collard greens without a pressure cooker.
The Importance of Acidification
When canning low-acid foods like collard greens, it’s crucial to acidify them to create an environment that’s inhospitable to bacteria and other microorganisms. Acidification involves adding an acidic ingredient, such as lemon juice or vinegar, to the food to lower its pH level. This step is critical in preventing the growth of botulism-causing bacteria, which can thrive in low-acid environments.
Preparing Collard Greens for Canning

What is the water bath canning method, and how does it work?
The water bath canning method is a simple and safe way to can collard greens without a pressure cooker. This method involves submerging the canning jars in a pot of boiling water, where they are heated to a temperature that is hot enough to kill off any bacteria or other microorganisms that may be present.
The water bath canning method works by using the heat from the boiling water to create a vacuum seal in the canning jars. As the jars are heated, the air inside the jar is pushed out, creating a partial vacuum. When the jars are removed from the pot and allowed to cool, the vacuum seal is created, which prevents any new air from entering the jar and causing spoilage.
How long do I need to process the collard greens in the water bath canner?
The processing time for canning collard greens in a water bath canner will depend on the altitude and the size of the canning jars. Generally, you will need to process the collard greens for 20-30 minutes for pint-sized jars and 30-40 minutes for quart-sized jars.
It’s also important to note that you will need to adjust the processing time based on your altitude. If you live at an altitude above 1,000 feet, you will need to add 5-10 minutes to the processing time. This is because the air pressure is lower at higher altitudes, which can affect the canning process.
How do I know if the collard greens are properly sealed and safe to eat?
To ensure that the collard greens are properly sealed and safe to eat, you will need to check the seals of the canning jars after they have cooled. Start by pressing on the top of the lid. If the lid does not move and the seal is tight, the jar is properly sealed.
You can also check the seal by listening for a “pop” sound as the jar cools. This sound indicates that the vacuum seal has been created. If you do not hear a “pop” sound, or if the lid moves when you press on it, the jar is not properly sealed and should be refrigerated and consumed within a few days.
How long can I store canned collard greens, and how should I store them?
Canned collard greens can be stored for up to 12 months in a cool, dark place. It’s best to store the jars in a pantry or cupboard, away from direct sunlight and heat sources. You should also keep the jars away from any sources of moisture, such as basements or attics.
