This is the ultimate set-it-and-forget-it comfort food. Tender beef, chewy barley, and soft vegetables simmer all day in a rich, savory broth for a deeply satisfying meal that tastes even better the next day.
For a thicker soup, mix 2 tbsp cornstarch with 3 tbsp cold water. Stir into the hot soup during the last 30 minutes of cooking on HIGH. For gluten-free, substitute barley with brown lentils or diced potatoes. Soup stores well in the fridge for up to 4 days and freezes for 3 months.
