Turn the Instant Pot to the sauté mode and add olive oil. Once hot, add the chunks of beef chuck roast in batches, searing until browned on all sides. Remove the browned beef and set aside.
In the same pot, add the quartered onion and sauté for about 3 minutes until translucent. Stir in the minced garlic and cook for another minute until fragrant.
Sprinkle in the ground cumin, dried oregano, smoked paprika, and chipotle powder. Stir for about 30 seconds to toast the spices.
Pour in the beef broth and apple cider vinegar, scraping the bottom of the pot to lift any browned bits.
Return the seared beef to the pot along with the bay leaves. Seal the lid and set the Instant Pot to cook on high pressure for 65 minutes.
Once the cooking time is up, allow the Instant Pot to naturally release pressure for about 20 minutes, then quick release the remaining pressure.
Open the lid and remove the bay leaves. Using two forks, shred the beef in the pot, mixing it with the juices for added flavor.
Taste and adjust seasoning with salt and pepper as needed.
Notes
Serve in warm corn tortillas topped with fresh cilantro and lime. Add diced onions and salsa for extra flavor.
