Taco beef made from ground beef is ground beef. Taco beef made from a slow-cooked chuck roast is something entirely different, tender, shredded, and saturated with the cooking liquid’s flavor in a way that no browning-and-draining process produces. The two are not interchangeable, and the chuck roast version feeds twice as many people from the same investment.
The Right Cut of Meat
Chuck roast, also labeled pot roast or shoulder roast depending on the store, is the correct cut for slow cooker shredded beef. It has significant intramuscular fat and connective tissue that breaks down over 8 hours of low heat into gelatin, which is what makes the shredded meat moist and flavorful rather than dry. A lean cut like round roast or sirloin does not have this fat and connective tissue content and produces dry, stringy shredded beef regardless of how long it cooks.
The Seasoning and Liquid
Combine in the slow cooker: a 3 to 4 pound chuck roast, a packet of taco seasoning or 2 tablespoons of homemade taco seasoning, a can of diced green chiles, half a cup of beef broth, and a tablespoon of lime juice. That is the entire preparation. No browning required, though searing the roast in a hot pan for 3 minutes per side before adding to the slow cooker adds a Maillard-reaction depth that the oven cannot replicate.
After Cooking
Cook on LOW for 8 to 10 hours or HIGH for 5 to 6 hours. The roast is done when it falls apart when pushed with a fork. Remove the roast, shred with two forks, and return the shredded meat to the cooking liquid. The liquid seasons the meat further as it soaks in. For the best result, let the shredded meat rest in the liquid for 15 minutes before serving. For homemade taco seasoning without the packet, the homemade taco seasoning guide takes 5 minutes.
