Trimming visible fat from a chuck roast before cubing prevents excessive greasiness in the final sauce, as rendered animal fat will otherwise pool on top of the liquid. For gluten-free requirements, substitute corn tortillas for flour varieties, though warming them first prevents tearing when rolling. To reduce sodium, replace commercial beef bouillon cubes with low-sodium beef broth or water seasoned with smoked paprika and cumin.
Cube the chuck roast uniformly into pieces measuring one to two inches so heat penetrates evenly over the seven to eight hour cooking window on low. Bouillon cubes require adequate liquid to dissolve fully, which is provided here by the enchilada sauce and moisture from the diced green chiles and onions. When shredding, discard any remaining cartilage or hard connective tissue that failed to melt during the simmer.
Operating an oven broiler requires close visual monitoring; position the baking sheet six inches from the heating element and watch for the cheddar cheese to bubble and brown in approximately three to four minutes. Assembled unbaked burritos tolerate refrigeration for up to twenty-four hours when tightly wrapped in plastic film, or freezing for two months before baking.
