In a large skillet over medium heat, brown the ground beef for about 5-7 minutes until fully cooked.

In the same skillet, sauté the chopped onion and minced garlic for 2-3 minutes until soft.

Transfer the browned meat and sautéed onions and garlic into your crockpot.

Stir in the kidney beans, black beans, diced tomatoes, and tomato paste.

Pour in the beef broth and stir to combine.

Sprinkle in the chili powder, cumin, paprika, salt, and black pepper.

Cover and cook on low for 6-8 hours or high for 3-4 hours.

After cooking, taste and adjust seasoning if needed; cook uncovered for 30 minutes for a thicker chili if desired.
