1. 1. Heat the olive oil in a large pot or Dutch oven over medium heat. Add the ground beef and cook, breaking it apart with a wooden spoon, until browned and cooked through, about 5-7 minutes. Drain any excess fat from the pot.

2. 2. Stir in the diced onion and minced garlic. Cook for 2-3 minutes, or until the onion is translucent and the garlic is fragrant.

3. 3. Add the diced tomatoes, tomato paste, kidney beans, black beans, chili powder, cumin, smoked paprika, cayenne (if using), salt, and pepper. Stir to combine everything thoroughly.

4. 4. Pour in the beef broth and bring the mixture to a boil. Reduce the heat to low, cover the pot, and let the chili simmer for 30-40 minutes, stirring occasionally, until the flavors have melded and the chili has thickened to your desired consistency.

5. 5. Ladle the hot Ground Beef Stovetop Chili into bowls and top with your favorite garnishes, such as shredded cheese, sour cream, diced onions, or fresh cilantro.
