Ingredient Notes

All the ingredients laid out for making a vegan cauliflower broccoli soup recipe with white beans, onion, celery, nutritional yeast and potato.
  • Oil: I used olive oil but any cooking oil works. For an oil-free soup, use a splash of water or broth.
  • Onion: White or yellow onion works.
  • Broccoli & Cauliflower: Use about 5 cups each of small florets or about 1 small head of cauliflower and broccoli. The amounts don’t have to be exact, you can use more if you like and vary the amount of cauliflower and broccoli.
  • Broth: Use any store-bought or homemade broth, vegetable stock or bouillon base.
  • Spinach: Fresh baby spinach or regular spinach is best.
  • White Beans: Drain and rinse canned beans. White beans work best here for their smooth, creamy texture though you could substitute chickpeas or another variety of white bean. Extra white beans? Try this Vegan White Bean Chili Recipe.
  • Nutritional Yeast: This adds a cheesy flavor the the soup.
  • Herbs & Spices: The recipe calls for dried thyme and oregano and optional cayenne pepper. To use fresh herbs, substitute 2-3 tbsp finely chopped fresh thyme and 1-2 tbsp fresh oregano.

Cooking Notes

  • Try to cut all the broccoli and cauliflower florets about the same size for even cooking.
  • I prefer to peel the potato but it’s not required.
  • The soup is really good with a bit of heat from the cayenne but it is an optional ingredient. You can also use red pepper flakes.
  • If you don’t have a blender, you can use an immersion blender directly in the pot and pulse until you reach your desired consistency. A traditional blender is suggested for best results though.
