In a large bowl, combine oregano and salt.
Add chopped cilantro, sliced garlic, and finely chopped chipotle peppers to the same bowl.
Simmer beef broth using beef bones or bouillon cubes, liquid, or powder.
Trim excess fat from beef and cut into two-inch chunks.
Add beef chunks to the spice mixture in the bowl and mix well using a wooden spoon or clean hands.
Incorporate sliced onions with the beef chunks and spice mixture, ensuring thorough mixing.
Pack the beef mixture into your jars, without compressing, leaving an inch of headspace at the top.
Pour hot beef broth into the jars, covering the mixture and maintaining the one-inch headspace. Wipe jar rims clean.
Load jars into the pressure canner, seal, and heat.
Vent steam for ten minutes, then apply pressure weight accordingly.
Maintain 11 lbs pressure for dial gauge or 10 lbs pressure for weighted gauge for 90 minutes (quarts) or 75 minutes (pints).
After canning time, turn off heat and allow the canner to depressurize.
Wait until pressure reads zero before removing the lid.
Let jars sit undisturbed for 24 hours.
Check seals, label jars, and store them appropriately.
