3 tablespoons vegetable oil
3 pounds ground beef chuck
2 large onions, finely chopped
1 green bell pepper, finely chopped
5 garlic cloves, minced
3 tablespoons pure ancho chile powder
3 tablespoons pure pasilla chile powder
3 tablespoons ground cumin
2 tablespoons ground coriander
1 tablespoon sugar
2 teaspoons chopped thyme
2 teaspoons chopped oregano
1 teaspoon freshly ground black pepper
1 teaspoon cayenne pepper
3 cups low-sodium beef broth
1 15-ounce can pinto beans
1 14-ounce can diced tomatoes with the juices
5 chipotle chiles in adobo, seeded and finely chopped
1 cup tomato sauce
1/4 cup tomato paste
1 tablespoon cider vinegar
Juice of 1 lime
In a large, heavy pot or a medium enameled cast-iron casserole, heat the oil. Add half of the ground beef and cook over high heat, breaking it up with a wooden spoon, until browned, about 5 minutes; transfer to a bowl with a slotted spoon. Brown the remaining ground beef. Return the first batch of browned beef to the pot.
Add the onions and pepper to the pot and cook over moderate heat, stirring occasionally, until the onions are translucent, about 8 minutes. Add the garlic, chile powders, cumin, coriander, sugar, thyme, oregano, black pepper and cayenne and cook for 10 minutes, stirring occasionally.
Stir in the beef broth, pinto beans, tomatoes, chipotles, tomato sauce, tomato paste and the vinegar. Simmer the chili over low heat for 1 1/2 hours, stirring occasionally. Add the lime juice, season with salt and serve.
MAKE AHEAD The chili can be refrigerated for up to 3 days.
