Creating this Keto Chili (no beans) is both fun and straightforward when you follow these steps:

1. Brown the Beef: In a large pot over medium heat, add ground beef. Cook until browned, breaking it up as it cooks.
2. Add Onions and Peppers: Stir in the diced onion and bell pepper. Sauté until softened, around 5-7 minutes.
3. Incorporate Garlic: Add the minced garlic to the pot and cook for an additional minute, allowing it to become fragrant.
4. Mix in Spices: Sprinkle chili powder, cumin, smoked paprika, salt, black pepper, and cayenne pepper into the pot. Stir until everything is evenly coated.
5. Add Tomatoes and Paste: Pour in the diced tomatoes and tomato paste, mixing thoroughly to combine all ingredients.
6. Pour in Broth: Add the beef broth and bring the mixture to a boil.
7. Simmer: Lower the heat and let the chili simmer for 30-35 minutes. Stir occasionally to prevent sticking. Adjust seasoning to taste.
8. Serve Hot: Once chili has thickened and flavors have melded, it is ready to serve.
9. Top and Garnish: Ladle into bowls, top with shredded cheddar cheese, and sprinkle with fresh cilantro if desired.
