Ingredients
This easy, comforting soup comes together with simple, wholesome ingredients:
- 2 tablespoons olive oil
- 1 small onion, diced
- 3 cloves garlic, minced
- 1 head cauliflower, chopped into florets
- 2 cups broccoli florets (plus extra for garnish)
- 4 cups vegetable broth
- 1 teaspoon dried thyme
- ½ teaspoon ground black pepper
- 1 tablespoon nutritional yeast (optional, for a cheesy hint)
- Salt, to taste
For Garnish:
- Crunchy croutons
- Fresh broccoli florets
- Red pepper flakes
- Drizzle of olive oil
- Fresh black pepper
Instructions
Here’s how to whip up this creamy, comforting soup:
- Sauté the aromatics:
Heat olive oil in a large pot over medium heat. Add diced onion and cook until softened and slightly golden, about 5-7 minutes. Stir in the minced garlic and cook for another minute, stirring constantly to avoid burning—this step creates a fragrant base that lays the foundation for all the rich flavors to come. - Cook the veggies:
- Add the chopped cauliflower and broccoli florets to the pot. Stir them thoroughly with the onions and garlic to coat them evenly in the oil and aromatics.
- Let them cook for 5-7 minutes, allowing the vegetables to soften slightly and absorb the flavors from the onions and garlic.
- Simmer the soup:
- Pour in the vegetable broth, stirring well to incorporate all the ingredients. Add the thyme, black pepper, and a pinch of salt, adjusting the seasoning as needed.
- Bring the mixture to a gentle boil, then reduce the heat to low and let it simmer uncovered for 20-25 minutes, or until the cauliflower and broccoli are tender and easily pierced with a fork.
- Blend until creamy:
Using an immersion blender, blend the soup until smooth and velvety, ensuring no large chunks remain unless you prefer a chunkier texture. For added variety, blend only half of the soup to leave some whole broccoli and cauliflower florets for a satisfying bite. - Add cheesy depth: Stir in the nutritional yeast for a rich, dairy-free cheesy flavor. It enhances the creaminess and adds a subtle umami depth that takes the flavor to the next level.
