In a mixing bowl, combine the ground beef, sea salt, dried oregano, dried basil, and optional garlic powder. Mix the ingredients thoroughly until well combined.
Form the mixture into meatballs of your desired size. A common size is about 1-1.5 inches in diameter.
Place the meatballs in the slow cooker.
Pour beef bone broth over the meatballs to provide moisture and flavor.
Cover the slow cooker with the lid.
Cook on low heat for 6-7 hours, allowing the meatballs to become tender and absorb the flavors of the broth.
Once the meatballs are done, you can garnish with fresh basil leaves for an extra burst of flavor and aroma.
Serve the Italian meatballs in bone broth hot.
