In a large skillet, brown the ground beef over medium-high heat. Drain off any excess grease. Transfer the browned beef to a 6-quart (or larger) slow cooker.
Add chopped onion and minced garlic to the skillet with a little residual grease (or a tiny bit of oil) and sauté until softened, about 5 minutes. Transfer to the slow cooker.
Add crushed tomatoes, tomato sauce, kidney beans, black beans, diced green chiles (if using), chili powder, cumin, oregano, cayenne pepper (if using), beef broth, salt, and black pepper to the slow cooker.
Stir all ingredients well to combine.
Cover and cook on LOW for 6-8 hours or on HIGH for 3-4 hours, or until the chili is rich and flavors are well blended.
Taste and adjust seasonings as needed. If the chili is too thin, you can uncover it for the last hour of cooking on high to allow some liquid to evaporate, or mash some of the beans against the side of the pot to thicken it.
Serve hot with your favorite toppings like shredded cheese, sour cream, green onions, and a side of cornbread.
Notes
For a spicier chili, increase the amount of cayenne pepper.
If you don’t have beef broth, chicken or vegetable broth can be substituted.
This chili can be made ahead of time and reheated. The flavors often deepen overnight.
