After cleaning, cut the fillets into smaller pieces according to the size of your jars. For pint jars, aim for 1- to 2-inch chunks, while quart jars can hold larger pieces.
Canning Process: How to Can Tuna in a Pressure Cooker
Canning tuna with a pressure cooker may seem daunting, but once you know the steps involved, it can be a straightforward process.
Preparing the Pressure Cooker
Fill the Canner: Add around 3 inches of water to the bottom of the pressure cooker. If your pressure cooker allows, add a little vinegar to prevent mineral build-up.
Preheat the Pressure Cooker: Turn on the burner to preheat the canner for efficient processing later on.
Packing the Jars
Fill Jars with Tuna: Using a funnel, pack the cleaned and minced tuna into the jars, leaving about 1 inch headspace at the top. This space helps to create a proper seal during the pressure canning process.
Add Salt (Optional): Sprinkle about 1 teaspoon of salt per pint jar or 2 teaspoons per quart jar directly onto the tuna. This step is optional, but it enhances flavor significantly.
Add Liquid (Optional): If desired, pour olive oil or boiling water over the tuna to fill the jars, again leaving that 1-inch headspace.
Remove Air Bubbles: Insert a clean knife or bubble freer inside the jar and gently slide it down the sides to release any trapped air bubbles.
Wipe the Rims: Use a clean cloth to wipe the rims of the jars to ensure a good seal.
Add Lids and Bands: Secure the lids and bands, but be sure not to over-tighten them; they only need to be snug.
Processing the Jars
Place Jars in Canner: Carefully place the filled jars into the preheated pressure cooker using your jar lifter. Ensure they are upright and spaced correctly for steam circulation.
Seal the Lid: Lock the lid of the pressure cooker, ensuring the pressure valve is set to the correct position.
Build Pressure: Turn up the heat, allowing the canner to reach the necessary pressure. For low-acid foods such as tuna, you will need to achieve a pressure of 10-11 pounds (or as specified by your pressure canner’s manual).
Time the Processing: Once the appropriate pressure is reached, start your timer. Process pint jars for 100 minutes and quart jars for 110 minutes.
Cool Down: When processing time is complete, turn off the heat and allow the pressure cooker to cool down naturally until the pressure gauge reads zero. Do not rush this step, as cooling too quickly can spoil the seal.
Storing Your Canned Tuna
Once the pressure cooker is cool and safe to open, it’s time to retrieve your beautifully canned tuna. Follow these steps:
Removing Jars
Check Seals: Ensure all jars have sealed properly. The lid should not flex up and down when pressed. If any jars haven’t sealed, store them in the refrigerator and use them within a week.
Let Jars Cool: Place the jars on a clean towel or cooling rack and allow them to cool at room temperature for 12-24 hours. This process helps set the seal further.
Labeling and Storing
Label Your Jars: After the jars have cooled completely, label them with the date of canning. This practice will help you track freshness.
Store in a Cool, Dark Place: Identify a suitable storage area, such as a pantry or cellar, where your jars can remain in a cool, dark environment. Avoid exposing them to sunlight or heat.

What is the best type of tuna for canning?
The best type of tuna for canning is typically albacore or yellowfin. Albacore tuna has a mild flavor and a firm texture, making it ideal for preserving. Its meat can withstand the canning process without losing much quality, ensuring a delightful taste in your final product. Yellowfin is another excellent choice; it has a slightly richer flavor and is still quite manageable for canning.
When selecting tuna, opt for fresh, high-quality fish to guarantee the best results. Look for bright, clear eyes and a shiny, reflective skin when purchasing fresh tuna. If you cannot find fresh tuna, good-quality frozen tuna can also work well, but be sure to thaw it properly before canning to maintain its flavor and texture.
Do I need to use a pressure cooker to can tuna?
Yes, using a pressure cooker is essential for safely canning tuna. Tuna is classified as a low-acid food, which means it must be processed at high temperatures to eliminate harmful bacteria, such as Clostridium botulinum. A pressure cooker allows you to achieve the required temperatures for safe canning, ensuring that your tuna is safely preserved for future use.
Water-bath canning is not recommended for tuna because it does not reach the necessary temperature to effectively kill off bacteria. Therefore, investing in a good-quality pressure cooker is crucial for successful and safe home canning of tuna.
How long should I process canned tuna in a pressure cooker?
Processing time for canned tuna in a pressure cooker typically ranges from 90 to 120 minutes, depending on the size of the jars and the altitude at which you are canning. For quart-sized jars, it is recommended to process for 100 minutes, while pint-sized jars generally require about 90 minutes. Always consult a reliable canning guide to ensure accuracy based on your specific circumstances.
It’s essential to maintain a consistent pressure throughout the processing time to ensure the contents are fully cooked and preserved. Adjusting for altitude is also crucial; higher elevations may require slight modifications to processing times. Always follow a tested recipe to keep your canning procedures safe.
Can I add seasonings or vegetables to canned tuna?
Yes, you can add seasonings to your canned tuna to enhance its flavor. Common additions include salt, pepper, and herbs like dill or parsley. However, while you can infuse flavors while canning, avoid adding low-acid vegetables, as they can interfere with the canning process. If you’d like to include vegetables, consider safely cooking and canning them separately.
When adding ingredients, keep in mind that you should not exceed the fill line of the jars. The focus should remain on the tuna as the primary ingredient to ensure proper preservation. Don’t hesitate to experiment with different herbs or spices to create a unique flavor profile that suits your taste.
How should I prepare tuna for canning?
Preparing tuna for canning involves several steps to ensure it’s safe and flavorful. Start by cleaning the tuna thoroughly, removing any bloodline, and cutting it into chunks of appropriate sizes that will fit into your jars. Rinse the pieces under cold water and pat them dry with a clean towel. This step is crucial to remove any impurities that could affect the flavor during the canning process.
Next, you can choose whether to pack the tuna raw or cooked. Raw packing will preserve more of the natural flavor and texture, while pre-cooked tuna may provide a different consistency. If you decide to cook it, ensure that you do not overcook it before canning. Whichever method you choose, be sure to follow specific guidelines regarding jar filling and headspace for compatibility with your pressure cooker.
How can I ensure my canned tuna lasts long-term?
To ensure long-term storage for your canned tuna, it is vital to follow proper canning procedures. Start with sterilized jars, clean equipment, and fresh tuna to reduce the risk of spoilage. After canning, store your jars in a cool, dark place away from direct sunlight and temperature fluctuations, as these factors can negatively impact the shelf life.
