How to Make It
Set Instant Pot on saute setting, and add oil. Add beef; cook until browned, about 10 minutes, stirring after 5 minutes. Transfer beef to a plate; set aside. Add onion and poblano to Instant Pot; cook, stirring occasionally, until starting to soften, about 3 minutes. Stir in tomato paste, chili powder, salt, black pepper, and sugar. Cook, stirring often, 2 minutes. Add browned beef, broth, tomatoes, beans, and, if using, bones; bring to a boil. Cover with lid, and set timer to 30 minutes on high pressure.
Carefully release steam according to manufacturer’s instructions. Remove and discard beef bones. Top servings evenly with cheese, sour cream, cilantro, and jalapeño slices.
