Why This Recipe Works

With its richly perfumed broth and mix of raw/cooked and hot/cold ingredients, this Vietnamese soup, called pho, seemed like a long shot for the slow cooker. But it turned out to be one of our easiest soups. Fish sauce and soy sauce punched up store-bought broth, which we further enhanced with bruised lemongrass, star anise, and cloves. And blade steak was a great and easy choice for this soup since it is so full of rich beefy flavor. Surprisingly, finicky rice noodles worked perfectly in the slow cooker; since the liquid didn't come to a full boil, the noodles cooked gently and did not break apart or turn mushy. Finishing with the requisite garnishes created a perfectly balanced soup.
