Add a bit of oil to a large skillet, and cook the ground beef over medium heat. Break it up as it cooks, browning on all sides.
Once the beef is browned and excess fat is drained, stir in the salt, minced onion, chili powder, cumin, red pepper flakes, and oregano. Mix well to evenly coat the meat with the spices.
Sterilize 4 pint-sized canning jars and their lids. (You can adjust the recipe to make more jars as needed, depending on your canner’s capacity.)
Choose either beef broth or tomato juice as your canning liquid. You'll need about ¾ cup of liquid per pint jar (about 3 cups total for this recipe).
Spoon the seasoned ground beef into the jars, packing it tightly but without overpacking. Leave about an inch of headspace at the top.
Pour the beef broth or tomato juice into each jar, ensuring the meat is mostly covered, but still leaving that inch of headspace.
Use a clean, damp cloth to wipe the rims of the jars to remove any grease or residue that could affect the seal.
Place sterilized lids on the jars and screw on the bands until they’re just finger-tight.
Process the jars in a pressure canner at 10 pounds of pressure for 75 minutes (for pints) or 90 minutes (for quarts). If you’re above 1,000 feet in altitude, adjust the pressure as needed (see notes).
After canning, turn off the heat and let the canner cool naturally. Once the pressure has dropped to zero, carefully remove the jars and place them on a towel-lined surface. Allow the jars to cool completely before storing them in a cool, dark place.
