Ingredients

Scale

Vegetables

  • 1/2 yellow onion (or 1/2 leek), chopped
  • 4 cloves garlic, minced
  • 2 lb golden potatoes, scrubbed, rinsed & diced
  • 1 large carrot, diced
  • 1 celery stick, chopped
  • 1 lb broccoli florets
  • 1/3 cup fresh chives, snipped for garnish

Pantry

  • 1 cup raw cashews
  • 78 cups vegetable stock, low sodium
  • 56 tbsp nutritional yeast
  • 1 pinch sea salt, to taste
  • 1 pinch red pepper flakes
  • 1/2 tsp turmeric (optional)

Instructions

  1. Sauté the onion: Preheat a heavy stock pot over medium-low heat and sauté the chopped onion in a splash of water or a drizzle of olive oil until translucent, ensuring a tender and flavorful base.
  2. Add aromatics and sweat vegetables: Sprinkle in sea salt and red pepper flakes, then add chopped celery and diced carrots. Toss everything well, cover with a lid, and let the mixture sweat a few more minutes until the carrots begin to soften, enhancing the overall flavor depth.
  3. Add main ingredients and simmer: Stir in minced garlic, diced potatoes, raw cashews, and vegetable stock. Bring the mixture to a simmer, then stir in the nutritional yeast. Cover and cook for about 20 minutes, or until the potatoes and cashews have softened thoroughly.
  4. Blend the soup: Carefully transfer the soup to a powerful blender and purée until silky smooth. A high-performance blender like a Vitamix yields the best results for a creamy texture, though an immersion blender can also be used.
  5. Cook broccoli: Pour the blended soup back into the pot and bring it to a simmer again. Add the broccoli florets, cover, and cook for 3 to 5 minutes until the broccoli is tender yet still has a slight bite. Alternatively, steam the broccoli separately during the soup’s cooking time and add it at the end.
  6. Adjust seasoning and consistency: Taste the soup and adjust with additional sea salt if needed. Add more vegetable stock if you prefer a thinner consistency.
  7. Serve and garnish: Ladle the hot soup into bowls and garnish with extra red pepper flakes and snipped fresh chives for a fresh, vibrant finish.

Notes

  • You can substitute the yellow onion with leek for a milder flavor.
  • Steaming broccoli separately helps retain its bright green color and texture better.
  • Soaking cashews for 2 hours beforehand can help achieve an even creamier blend.
  • Adjust the amount of red pepper flakes depending on your spice preference.
  • This soup keeps well refrigerated for up to 3 days and also freezes well for up to 2 months.
