Preheat the pressure cooker on sauté mode and heat the vegetable oil until shimmering. Sear the seasoned beef pieces on all sides until a deep brown crust forms to lock in juices and enhance flavor.

Scatter chopped onion, jalapeño (if using), and minced garlic evenly over the seared beef to build aromatic layers.

Pour crushed tomatoes, salsa verde, and beef broth over and around the meat, gently swirling to combine while keeping the beef mostly at the bottom for proper braising.

Secure the lid and seal the valve. Set the pressure cooker to high pressure and cook for 40 minutes to tenderize the beef by breaking down connective tissues.

Allow the pressure to release naturally for 10 minutes, then perform a quick release to remove any remaining pressure, ensuring the beef remains moist and shreddable.

Transfer the beef to a plate or cutting board and shred finely using two forks. Skim off any excess fat from the cooking liquid left in the pot.

Return shredded beef to the cooking liquid and stir to evenly coat. Serve warm by filling tortillas or bowls, topping with cheddar cheese, sour cream, guacamole, salsa, and fresh cilantro.
