Add vegetable oil and onions to a large dutch oven on medium heat and cook until the onions are translucent, about 6-8 minutes.
Add the garlic, and cook for 1 minute stirring well.
Add the ground beef, breaking apart as you cook it for 6-8 minutes but leave the chunks a bit larger, and allow the beef to sear well.
Add in the salt, ancho chile powder, cumin, paprika and brown sugar and stir well, cooking for 1 minute.
Add in the diced tomatoes, and tomato paste and whisk well until the tomato paste is well mixed in.
Add in the beef broth and bring to a simmer, reduce the heat to medium low and cook for 1 hour, stirring every fifteen minutes.
Chili is done when the beef broth is reduced to the right consistency where the ground beef is not lost in the gravy.
