Shredded sharp cheddar cheese, for garnish (optional)
Sour cream, for garnish (optional)
Heat a large pot over medium-high heat. Once hot, add in the ground beef, chopped bacon, chopped onion, and minced garlic. Cook and crumble the ground beef mixture until the beef is browned and the bacon is cooked, about 15 minutes.
Once the ground beef mixture is cooked and crumbled, add in the spices (chili powder, smoked paprika, oregano, cumin, sea salt, and pepper), stir everything together, and let it cook for 2-3 minutes until the spices are darkened slightly and fragrant.
Add the beef broth, tomato paste, fire-roasted tomatoes, and beans to the pot, then stir the chili together until bubbling, and let it simmer on low heat for 5-10 minutes.
Remove the chili from heat, then garnish with the green onions, cheese, and sour cream and serve!
