Ingredients

  • 4 cups cauliflower florets
  • 5 cups broccoli florets
  • 10 cloves garlic peeled
  • 3 tablespoons olive oil divided
  • 1/2 medium yellow onion finely diced
  • 3 cups vegetable broth
  • 2 cups shredded white cheddar cheese
  • 1/4 teaspoon ground black pepper
  • 1/4 teaspoon salt

Instructions

  • Preheat oven to 400ºF.
  • Place cauliflower, broccoli, and garlic cloves on a baking sheet. Drizzle 3 tablespoons of olive oil on top and toss so that the veggies are fully coated.
  • Roast veggies at 400ºF for about 20 minutes, or until the broccoli begins to brown.

  • While the veggies are roasting, sauté the yellow onion in about 1 tablespoon of olive oil with a pinch of salt. Once they are translucent, pour in the vegetable broth and let simmer for a few minutes.
  • Transfer all of the ingredients to a high-speed blender (including the cheese). If desired, set aside a couple roasted florets for topping.

Tips & Notes

  • Storage: Store soup in an airtight container in the refrigerator for up to 5 days. 
  • Freezing Instructions: For best taste and texture, freeze this soup before adding in the cheese. When reheated, soups with dairy tend to be a little grainy. Transfer soup to freezer-safe containers for up to 3 months. If you've already made the soup as-is (with the cheese), simply freeze the soup, and reheat on super low heat with a little extra broth.
  • Thinner Soup: Add more vegetable broth for a thinner soup.
