Ingredients You’ll Need
Tip: You’ll find the full list of ingredients and measurements in the recipe card below.
- 2 tablespoons extra virgin olive oil
- 1 sweet onion, diced
- 3 cloves garlic, minced
- 1 head cauliflower, cut into florets
- 2 parsnips, sliced (about 1½ cups)
- 1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme)
- ¼ teaspoon salt
- ¼ teaspoon freshly ground black pepper
- 1 (15-ounce) can cannellini beans, drained and rinsed
- 4 cups vegetable broth
These ingredients create a soup that is naturally creamy, gently aromatic, and well-balanced. The thyme adds warmth without overwhelming the vegetables, while the beans quietly enhance texture and nutrition.
Let’s Get Started
Begin by heating the olive oil in a large pot over medium heat. Once warm, add the diced onion and cook for about 4–5 minutes, stirring occasionally, until soft and translucent. Add the minced garlic and cook for another 30 seconds, just until fragrant.
Next, add the cauliflower florets and sliced parsnips to the pot. Stir well to coat the vegetables in the oil and aromatics. Sprinkle in the thyme, salt, and black pepper, allowing the seasoning to evenly distribute.
Pour in the vegetable broth and add the drained cannellini beans. Stir to combine, then bring the mixture to a gentle boil. Once boiling, reduce the heat to low, cover the pot, and simmer for 20–25 minutes, or until the cauliflower and parsnips are fork-tender.
Remove the pot from heat and let the soup cool slightly. Using an immersion blender, blend the soup directly in the pot until smooth and creamy. Alternatively, carefully transfer the soup to a blender in batches, blending until silky. Taste and adjust seasoning as needed before serving.
Servings and Pairing
This recipe yields approximately 4 servings, making it ideal for a small family meal or a few days of lunches. Serve Cauliflower and Parsnip Soup on its own for a light meal, or pair it with crusty bread, sourdough toast, or a simple green salad for something more substantial.
It also works well as a starter alongside roasted vegetables, grain bowls, or baked tofu. The soup’s mild flavor makes it an excellent companion to heartier dishes without feeling overwhelming.
Variations
This soup is easy to customize based on preference or pantry availability. For extra richness, a splash of coconut milk or oat cream can be stirred in after blending. Roasted cauliflower can replace simmered cauliflower for a deeper, nuttier flavor.
Herbs can also be adjusted—rosemary or sage offer a slightly stronger profile, while parsley adds freshness. For added warmth, a pinch of nutmeg or white pepper blends beautifully with parsnips.
Storage Tips
Cauliflower and Parsnip Soup stores well and is ideal for meal prep. Allow the soup to cool completely before transferring it to an airtight container. It will keep in the refrigerator for up to 4 days.
For longer storage, freeze the soup in individual portions for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop, stirring occasionally to restore its creamy texture.
FAQs
Can this soup be made ahead of time?

Can I make it without beans?
Yes, though the soup will be slightly thinner. Additional cauliflower can help maintain thickness.
