Start by preparing the chicken. If starting with whole birds, part the birds into whatever pieces you desire and save the carcasses for making broth. Roast the carcasses and make a chicken broth for canning, or start with prepared chicken broth and pre-cut chicken pieces. Chicken may be canned boneless or bone-in, with or without skin, and in large pieces or small chunks, based on your preference.
Preheat your pressure canner and prepare your jars/lids/rings.
Brown the chicken in a bit of oil on all sides and then pack into prepared canning jars, leaving 1 1/4 inch headspace.
Add salt, if desired. The recommended amount is 1 tsp per quart or 1/2 tsp per pint. Adjust to your tastes, or omit.
Cover the chicken in boiling chicken broth (or water), still maintaining 1 1/4 inch headspace. Adjust pieces to be below the liquid line and de bubble jars. Adjust headspace if necessary.
Wipe jar rims to remove any oil and seal jar to finger tight with 2 part canning lids.
Load the canning jars into the pressure canner, packing it according to the manufacturer's directions.
Close the lid on the pressure canner, but don't start bringing it up to pressure yet. Turn up the heat and allow the canner to vent steam for a full 10 minutes to ensure that the chamber is completely full of steam before sealing the canner completely and bringing it up to pressure.
Canning pressure depends on altitude and the type of canner used. See notes below for specifics.
Once at the specified pressure, start the timer. Canning times are as follows: For Boneless chicken (raw or hot pack), process jars at pressure for 75 minutes for pints and 90 minutes for quarts. For bone-in chicken (raw or hot pack), process jars for 65 minutes for pints and 75 minutes for quarts.
Once the canning time is complete, turn off the heat and allow the canner to cool completely before removing the jars.
Check seals, and store any unsealed jars in the refrigerator for immediate use.
Properly canned and sealed jars will maintain peak quality on the pantry shelf for 12 to 18 months after canning. Remove bands for storage. Refrigerate after opening.
