In a large Dutch oven or pot over medium-high heat, add the lean ground beef.
Cook the beef until browned, breaking it into small crumbles with a wooden spoon.
Add the diced onion and minced garlic to the pot and sauté for 5 minutes until the onion is translucent.
Stir in the tomato paste, chili powder, cumin, paprika, oregano, and cayenne, cooking for 2 minutes to toast the spices.
Add the crushed tomatoes, beef bone broth, and drained kidney beans to the mixture.
Bring the liquid to a light boil, then reduce the heat to low.
Simmer uncovered for 30 to 35 minutes, stirring occasionally to prevent sticking.
Season with sea salt and black pepper to taste before serving.
