Why This Recipe Works

To build a flavorful base for this simple but comforting soup in a slow cooker, we needed to get out our skillet to sauté a hefty amount of onions with tomato paste and thyme and then deglaze the pan with wine, scraping up the flavorful browned bits left behind. This simple step made a world of difference in the soup's flavor and allowed us to skip the tedious process of browning the meat. To simplify things further we used trimmed beef blade steak, which we shredded after it had become meltingly tender in the slow cooker—no need to cut the meat into pieces to start. The addition of soy sauce to the broth base added a surprising amount of flavor. Since pearl barley can absorb two to three times its volume in cooking liquid, we needed to be judicious in the quantity we added to the soup. A modest ¼ cup was all that was needed to lend a pleasing velvety texture without overfilling the slow cooker with swollen grains.
