Begin by heating a large skillet over medium heat. Add the ground beef to the skillet and cook until fully browned, about 6-8 minutes. Drain excess grease.

In your Crockpot, add the browned ground beef along with the black beans, corn, diced tomatoes, and tomato paste. Pour in the beef broth, chopped onion, minced garlic, and all spices. Stir thoroughly.

Cover the Crockpot and set it to low heat for 6-8 hours or high heat for 3-4 hours.

Once cooked, give your chili a good stir and ladle it into bowls. Top with shredded cheese, sour cream, and green onions.
