  • 2 tablespoons (30 g/1.1 oz) ghee or lard
  • 1 small (70 g/2.5 oz) white or yellow onion, finely chopped
  • 1 clove garlic, minced
  • 1 small (250 g/8.8 oz) head of broccoli
  • 1 large (64 g/2.3 oz) celery stalk
  • 2 cups (480 ml) chicken stock, bone broth, or vegetable stock (page 13)
  • 7.1 ounces (200 g) fresh or frozen spinach
  • ¼ cup (60 g/2.1 oz) crème fraîche or sour cream
  • 2.6 ounces (75 g) blue cheese, crumbled
  • 1 tablespoon (15 ml/0.5 oz) fresh lemon juice
  • 1 cup (20 g/0.7 oz) fresh basil, plus more for garnish, or 2 tablespoons (30 g/1.1 oz) Avocado and Kale Pesto (page 19)
  • Salt and pepper

Grease a large soup pot with the ghee and heat over medium heat. Add the onion and garlic and cook until fragrant, 3 to 5 minutes. Meanwhile, cut the broccoli into small florets.

Bring to a boil and cook for about 12 minutes. Add the spinach and cook for about 1 minute. Add the crème fraîche, blue cheese, lemon juice, and fresh basil. (Reserve some blue cheese for garnish, if you like.) Remove from the heat and use an immersion blender to process until smooth. (Or, if you’re using a regular blender, let the soup cool down slightly before pouring it into the blender.) Taste the soup, add salt and pepper, then pulse again.

Divide among four serving bowls, drizzle each with 1 tablespoon (15 ml/0.5 oz) of the olive oil, and garnish with fresh basil. Serve immediately, or let the soup cool down and store in the fridge for up to 3 days, or freeze in manageable portions for up to 3 months.
