Total time: 
Yield: 6 slightly heaping 1-cup servings
  • 2 tablespoons olive oil
  • 1 large onion, diced (divided)
  • 8 oz (225 g) button mushrooms, quartered
  • 4 cloves garlic, minced
  • 1 teaspoon minced fresh rosemary
  • 1 teaspoon minced fresh thyme
  • 4 cups (.95 liter) low-sodium beef stock
  • 1 teaspoon Worcestershire sauce (see Note)
  • 1 bay leaf
  • ¼ teaspoon salt
  • ⅛ teaspoon black pepper
  • 2 large stalks celery, chopped
  • 2 large carrots, chopped
  • ¾ lb (350 g) cooked, cubed pot roast (about 3 cups)
  • ½ cup (70 g) frozen green peas, thawed
  • 1 teaspoon arrowroot starch, dissolved in 1 tablespoon cold water to make a slurry (see Note below)
  • 2 tablespoons minced fresh parsley, for garnish
  1. Heat the oil in a medium saucepan over medium-high heat. Add half of the onion and cook until deep brown, about 5 minutes, stirring occasionally and adding a splash of water as necessary if the onion starts to get too dark in spots.
  2. Turn heat down to medium and add the mushrooms; cook until browned, about 4 to 6 minutes, stirring occasionally. Add the garlic, rosemary, and thyme and cook 1 minute more, stirring constantly.
  3. Add the stock, Worcestershire sauce, bay leaf, salt, black pepper, celery, carrot, and the remaining half of the onion. Bring to a boil over high heat, then turn heat down to simmer, cover the saucepan, and cook until the veggies are tender, about 20 minutes.
  4. Add the pot roast, peas, and arrowroot slurry and cook 5 minutes more.
  5. To serve, ladle into bowls and sprinkle the parsley on top.
Arrowroot Starch: If keeping this dish grain-free isn’t an issue, you can substitute cornstarch for the arrowroot starch.

Worcestershire Sauce: Omit this for strict paleo and Whole30.
