Fall-apart slow cooker beef barbacoa finished under the broiler for crispy, caramelized edges you won"t get from the slow cooker alone.
Don"t skip the reduce-and-broil step — it"s what separates this from standard slow cooker barbacoa. If you"re short on time, a hot cast-iron skillet works instead of the broiler; just crisp the shredded meat in batches for 2-3 minutes per side. Leftovers keep well in the fridge for 4 days or frozen (in the sauce, before broiling) for up to 3 months.
