Choose the right cut: beef chuck roast is perfect for barbacoa because it becomes tender and shreddable after pressure cooking. Adjust the heat by adding more or fewer chipotle chilies to your preference. Browning the beef adds depth and complexity to the flavor. Letting the pressure release naturally helps keep the beef tender and juicy. Barbacoa tastes even better the next day after the flavors meld. Variations include using lamb shoulder or boneless goat meat, adding smoked paprika or liquid smoke for extra smoky flavor, or making a vegetarian version with jackfruit or mushrooms. Serve with warm tortillas, fresh cilantro, diced onions, lime wedges, crumbled queso fresco, sliced avocado, or pickled red onions for extra flavor and texture. Store leftovers in an airtight container in the fridge for up to 4 days or freeze for up to 3 months.
