Place beef in a large deep skillet over medium high heat and cook until browned, breaking it up with a wooden spoon. Scoop it out and set aside.
Add onion and garlic and cook until onion starts to soften, about 5 minutes. Add tomato paste, oregano, cumin, broth, chili powder, brown sugar, vinegar, salt and cinnamon, stir it all up and bring it to a simmer.
Add the beef and let it all simmer over low heat for about 30 minutes until liquid is reduced.
Divide among bowls, garnish with cheese and scallions and sour cream and serve!
Notes
Ground Beef: We recommend the 80/20 fat version for the very best flavor.
Vinegar: You’re looking for cider vinegar for this recipe, which can be found with all the other vinegars in this recipe
Brown Sugar: I know, it’s a surprise to find sugar in a chili recipe, but the brown sugar blends perfectly with all the savory spices you have going on
Toppings: We like sour cream, scallions and shredded cheddar with our cinnamon chili, but if you have other topping favorites for chili, go for it!
