Pressure canning is a popular method of food preservation that involves using high pressure to kill off bacteria and other microorganisms that can cause spoilage. While it’s commonly used for canning raw foods like vegetables and meats, many people wonder if it’s possible to pressure can cooked food. In this article, we’ll delve into the world of pressure canning and explore the possibilities of canning cooked food.
Understanding Pressure Canning
Before we dive into the specifics of canning cooked food, it’s essential to understand the basics of pressure canning. Pressure canning involves using a pressure canner, a specialized pot designed to withstand high pressures, to heat food to a temperature that’s hot enough to kill off bacteria and other microorganisms. The pressure canner is equipped with a gauge that measures the pressure inside the pot, and a regulator that controls the pressure.
The process of pressure canning involves several steps:
- Preparing the food: This includes washing, chopping, and cooking the food as desired.
- Packing the food: The prepared food is packed into clean, sterilized jars, leaving a small amount of headspace.
- Adding liquid: A liquid, such as water or broth, is added to the jar to cover the food.
- Sealing the jar: The jar is sealed with a lid and ring, and then placed in the pressure canner.
- Processing the food: The pressure canner is heated to a high temperature, and the pressure is increased to a level that’s sufficient to kill off bacteria and other microorganisms.
- Cooling the food: After the processing time is complete, the pressure canner is allowed to cool, and the jars are removed and allowed to cool.
Can You Pressure Can Cooked Food?
Now that we’ve covered the basics of pressure canning, let’s address the question of whether it’s possible to pressure can cooked food. The answer is yes, but with some caveats.
Cooked food can be pressure canned, but it’s essential to follow safe canning practices to ensure that the food is heated to a temperature that’s hot enough to kill off bacteria and other microorganisms. Cooked food can be more challenging to can than raw food because it may not be as acidic, and it may contain more moisture.
To safely pressure can cooked food, it’s essential to:
- Use a tested recipe: Only use recipes that have been tested for safety and efficacy.
- Acidify the food: Add an acidic ingredient, such as lemon juice or vinegar, to the food to increase its acidity.
- Use a pressure canner: A pressure canner is essential for canning cooked food, as it allows for high-pressure processing that can kill off bacteria and other microorganisms.
- Process the food for the correct amount of time: The processing time will depend on the type of food, the altitude, and the pressure canner being used.

- Process the food for the correct amount of time, taking into account the type of food, the altitude, and the pressure canner being used.
- Use a thermometer to ensure that the food is heated to a temperature that’s hot enough to kill off bacteria and other microorganisms.
Common Mistakes to Avoid
When pressure canning cooked food, it’s essential to avoid common mistakes that can lead to foodborne illness or spoilage. Some common mistakes to avoid include:
- Not following a tested recipe
- Not acidifying the food
- Not processing the food for the correct amount of time
- Not using a pressure canner that’s specifically designed for canning cooked food

Can You Pressure Can Cooked Food?
Yes, you can pressure can cooked food. In fact, pressure canning is a great way to preserve cooked meals, such as stews, soups, and meats, by killing off any bacteria that may be present and creating a vacuum seal that prevents new bacteria from entering the jar. This method is especially useful for preserving low-acid foods, which are more susceptible to spoilage.
When pressure canning cooked food, it’s essential to follow safe canning practices to ensure that the food is heated to a high enough temperature to kill off any bacteria. This typically involves heating the food to 240°F (115°C) for a specified period, usually 30-60 minutes, depending on the type of food and the altitude. It’s also crucial to use a pressure canner that is specifically designed for canning, as it will provide the necessary pressure and temperature control to ensure safe canning.
What Are the Benefits of Pressure Canning Cooked Food?
Pressure canning cooked food offers several benefits, including convenience, cost-effectiveness, and nutrition preservation. By canning cooked meals, you can enjoy your favorite dishes throughout the year, even when the ingredients are out of season. Additionally, pressure canning helps preserve the nutrients in the food, as it uses high heat to kill off bacteria, rather than relying on acidity or salt.
Another significant benefit of pressure canning cooked food is that it allows you to create a stockpile of emergency food, which can be essential in case of natural disasters or power outages. Pressure-canned food can be stored for up to 12 months, making it an excellent option for preppers and those who want to be prepared for any situation.
What Types of Cooked Food Can Be Pressure Canned?

What Are the Safety Considerations for Pressure Canning Cooked Food?
When pressure canning cooked food, safety is paramount. The most significant risk is botulism, a potentially fatal illness caused by the bacteria Clostridium botulinum. To minimize this risk, it’s essential to follow safe canning practices, including heating the food to a high enough temperature, using a pressure canner that is specifically designed for canning, and following tested recipes and guidelines.
Another safety consideration is the risk of spoilage. To minimize this risk, it’s essential to use clean equipment and jars, as well as to follow proper sterilization and sealing procedures. Always check the jars for signs of spoilage before consuming the food, and never consume food that is spoiled or has an off smell.
Can I Pressure Can Cooked Food in a Water Bath Canner?
No, you should not pressure can cooked food in a water bath canner. Water bath canners are designed for canning high-acid foods, such as jams and pickles, and are not suitable for canning low-acid foods, such as meats and stews. Pressure canning requires a pressure canner that is specifically designed for canning, as it provides the necessary pressure and temperature control to ensure safe canning.
Using a water bath canner for pressure canning can result in under-processed food, which can lead to spoilage and foodborne illness. Always use a pressure canner that is specifically designed for canning, and follow tested recipes and guidelines to ensure safe canning.
How Do I Store Pressure-Canned Cooked Food?
Pressure-canned cooked food should be stored in a cool, dark place, such as a pantry or cupboard. The jars should be kept away from direct sunlight and heat sources, as this can cause the food to degrade. It’s also essential to check the jars regularly for signs of spoilage, such as swelling or leakage.
When storing pressure-canned cooked food, it’s also essential to keep the jars in a single layer, rather than stacking them. This will help prevent the jars from becoming damaged or cracked, which can lead to spoilage. Always label the jars with the date and contents, and use the “first in, first out” rule to ensure that the oldest jars are consumed first.
