Notes
Storage. Let the pot roast cool completely before storing. Transfer meat and juices to an airtight container. Keep some of the juices with the meat to help it stay moist and flavorful. Store in the refrigerator for up to 4 days. Freezing. Shred the pot roast first and allow it to cool. Portion into freezer-safe bags or containers, including some of the cooking liquid. Label with the date and store in the freezer for up to three months. For easier use later, freeze in meal-sized portions.Reheating. From the fridge, reheat in a microwave-safe dish, covered, on medium power in one-minute intervals, stirring occasionally until hot. You can also reheat over medium-low heat on the stovetop with a splash of broth or the reserved juices until warmed through.From frozen, thaw overnight in the refrigerator for best texture. Reheat using microwave or stovetop methods above, or reheat straight from frozen on the stovetop with a little extra broth, covered, over low heat.
