Prepare a pressure canner for hot pack according to the manufacturer's instructions. For most models, this means adding the bottom trivet along with 2-3 inches of water. Next, bring it to a gentle simmer and keep it warm while you get the broth into jars.
Rinse out the Dutch oven, then return the broth to the oven and bring to a simmer.
Ladle the hot broth into prepared and sanitized jars. Leave an inch (2.5 cm) of headspace.
Remove air bubbles with a bubble remover tool, then check to make sure you still have the proper headspace. Wipe the jar rim to remove any food residue, then put the lid and band on the jar.
Adjust to fingertip tight, then repeat until all of your jars are filled.
Load the jars into the pressure canner, adding two inches (five centimeters) of simmering water.
Put the lid on the canner, then turn it to the locked position.
Adjust the heat to medium-high, then vent steam for 10 minutes.
Put the weighted gauge or the counterweight on the vent, then bring the pressure to 10 lbs for a weighted-gauge canner or 11 lbs for a dial gauge. Altitude adjustments below in the notes.
Process pints for 20 minutes and quarts for 25 minutes.
Once the time has elapsed, turn off the heat, then allow the canner to depressurize on its own. Let the canner sit for five more minutes after that before removing the lid.
Cool the jars in the canner for 10 minutes, then remove them from the pressure canner and let them continue cooling on the counter.
After 12 hours, store the jars, checking the seals and labeling each one with the date before you do so.
