Ingredients:
- 1 tablespoon coconut oil
- 1 small onion, halved and thinly sliced
- 6 ounces fresh shiitake mushrooms, stemmed and sliced
- 2 cloves garlic, minced
- 2 teaspoons minced fresh ginger
- 5 cups Beef Bone Broth or Whole30-compliant beef broth
- 2 tablespoons coconut aminos
- 2 teaspoons Red Boat fish sauce
- 1 teaspoon kosher salt
- 2 medium zucchini
- 12 ounces boneless beef sirloin steak, thinly sliced across the grain (see Tip)
Instructions:
# In a large pot, heat the coconut oil over medium heat. Add the onion and cook, stirring, until softened, about 2 minutes. Add the mushrooms and cook, stirring, for about 3 minutes. Add the garlic and ginger and cook, stirring, until fragrant, about 30 seconds. Add the broth, coconut aminos, fish sauce, and salt. Bring to a boil; reduce the heat to medium-low and simmer, uncovered, for 5 minutes.
# Meanwhile, use a spiralizer (or julienne peeler) to cut the zucchini lengthwise into long, thin strands (or use a regular vegetable peeler to cut the zucchini lengthwise into thin ribbons). Add the zucchini noodles to the simmering soup and cook until just tender, about 1 1/2 minutes. Add the sliced steak and simmer until just cooked, 30 to 60 seconds. Ladle the soup into bowls and serve with the toppings of your choice.
