Why this soup matters to me — honest kitchen reflections

  • I love how this soup turns out creamy without any dairy, just honest, plant-based ingredients.
  • There’s something satisfying about blending the cashews until silky—like a little kitchen magic.
  • I’ve made this soup more times than I can count, each batch a little more perfect than the last.
  • It’s become a signature dish for me, especially when I want something wholesome and quick.

The inspiration behind my favorite vegan soup

  • This recipe was born out of a craving for comfort that’s both wholesome and quick.
  • One rainy Saturday, I threw together what I had—broccoli, cashews, and a few spices—and realized I’d stumbled on something special.
  • Since then, it’s been my go-to, especially during busy weeks when I still want to eat well.

The story behind the green and gold comfort in a bowl

  • The classic broccoli cheddar soup hails from American comfort food traditions.
  • Vegan adaptations often use cashews or nutritional yeast to mimic cheesy flavors.
  • Broccoli was once considered a luxury vegetable in Europe, now a staple in health-centric dishes.
  • Nutritional yeast, a key ingredient here, is a deactivated yeast that adds umami and cheesy notes.
  • The combo of broccoli and cheddar (or its plant-based cousins) is a beloved pairing in many recipes worldwide.

Ingredient quirks and how to tweak them

  • Broccoli: Fresh or frozen, it’s vibrant and crisp when cooked right. Overcooking dulls the color, so watch it.
  • Cashews: They create that luscious, cheesy base. Soak well for a smoother blend, or they’ll be gritty.
  • Nutritional Yeast: Adds cheesy umami, a little smoky when toasted. Can skip if you prefer cleaner flavors.
  • Garlic & Onion: Build the base flavor, sauté until fragrant but not burnt—smell should be sweet and inviting.
  • Lemon Juice: Brightens up the richness, add at the end to lift the flavors.

Focus on Broccoli and Cashews

Broccoli:

  • The bright green color of broccoli is a sign it’s cooked just right—tender yet vibrant.
  • During cooking, broccoli releases a fresh, earthy aroma that signals it’s nearly done.
  • Frozen broccoli can be just as good as fresh, especially when you want convenience and color retention.

Cashews:

  • Cashews become ultra-creamy when soaked and blended, creating that cheese-like texture.
  • They have a mild, nutty flavor that balances well with the savory elements.
  • Roasting or toasting the cashews beforehand adds a smoky depth.

Smart ingredient swaps to suit your pantry and preferences

  • Dairy-Free: Use coconut milk or vegan cheese for a similar creamy, rich flavor.
  • Low-Sodium: Opt for no-salt-added broth and reduce added salt.
  • Nut-Free: Use cooked white beans or silken tofu for creaminess.
  • Gluten-Free: Ensure broth and seasonings are gluten-free.
  • Extra Protein: Add cooked lentils or chickpeas for heartiness.

Equipment & Tools

  • Large pot: To cook vegetables and broth
  • Blender: To create a smooth, creamy cashew base
  • Measuring cups and spoons: To measure ingredients accurately
  • Ladle: To serve the soup

Method
 

  1. Heat a large pot over medium heat, add a splash of oil, and sauté chopped onion and minced garlic until fragrant and translucent, about 5 minutes. The aroma should be sweet and inviting as the onions soften.
  2. Add the broccoli florets to the pot and cook for another 3-4 minutes, stirring occasionally, until the broccoli turns bright green and begins to soften. You’ll notice a fresh earthy aroma as it cooks.
  3. Pour in the vegetable broth, bring the mixture to a gentle simmer, and cook uncovered until the broccoli is tender, about 10 minutes. The broth will bubble gently, and the vegetables will soften easily when pierced with a fork.
  4. While the soup simmers, soak the cashews in hot water for 10 minutes, then drain. This helps them blend into a silky, cheese-like cream.
  5. Add the drained cashews, water, nutritional yeast, and lemon juice to a blender. Blend until completely smooth and creamy, about 1-2 minutes. The mixture should be silky and thick, with a nutty, cheesy aroma.
  6. Stir the cashew cream into the simmering soup, mixing well to combine. Let it simmer for another 5 minutes, allowing the flavors to meld and the soup to thicken slightly.
  7. Season the soup with salt and pepper to taste, and add a pinch of smoked paprika if you like a smoky depth. Adjust seasonings until the flavor feels balanced and vibrant.
  8. If the soup feels too thick, stir in a little more broth or water until it reaches your desired consistency. It should be creamy but pourable, with some broccoli florets remaining slightly crisp.
  9. Remove the pot from heat and let the soup sit for 5 minutes; this helps it thicken slightly and improves the flavor. Then, ladle into bowls and serve hot, garnished with a sprinkle of nutritional yeast or fresh herbs if desired.
