- Garlic: Fresh garlic cloves provide aromatic flavor and warmth.
- Cauliflower: The star of the dish! Choose a fresh, firm head of cauliflower and cut it into florets.
- Chestnuts: Use cooked and peeled chestnuts — they add a naturally sweet, nutty flavor and creamy texture. You can use vacuum-packed, jarred, or freshly roasted chestnuts.

- Salt and Pepper: Keep the seasoning simple to let the natural flavors shine.
- Extra Olive Oil (for serving): A drizzle before serving adds richness and enhances the flavor.
If you’d like to make this soup even more indulgent, you can stir in a splash of unsweetened almond milk or coconut milk for extra creaminess.
Step-by-Step Instructions
Here’s how to make the perfect cauliflower and chestnut soup step by step:
Step 1: Sauté the aromatics
Heat 2 tablespoons of olive oil in a large pot over medium heat. Add the chopped onion and cook until it becomes soft and translucent, about 5 minutes.
Step 2: Add the garlic
Add 3 minced garlic cloves and sauté for another minute, until fragrant.
Step 3: Cook the cauliflower
Add 1 head of cauliflower, cleaned and cut into florets. Stir well to coat with the olive oil, onion, and garlic. Sauté for 3–4 minutes to enhance the flavor.
Step 4: Add chestnuts and liquid
Add 1 cup of cooked and peeled chestnuts to the pot. Pour in enough water or vegetable broth to cover the vegetables.
Step 5: Season and simmer
Add 1 teaspoon of salt and ½ teaspoon of black pepper. Bring to a boil, then reduce the heat and simmer until the cauliflower is tender — about 15–20 minutes.
Step 6: Blend until creamy
Carefully transfer the soup to a blender (or use an immersion blender) and blend until smooth and creamy. Adjust seasoning if needed.
Step 7: Serve and enjoy
Pour into bowls, drizzle with a little olive oil, and serve with crusty bread or homemade croutons.
Recipe Tips
- Use fresh cauliflower for the best flavor and texture. Frozen cauliflower can work too, but fresh gives a richer taste.
- Don’t skip the sautéing step — it enhances the flavor and creates a deeper, more aromatic soup.
- Blend until silky smooth. The key to the perfect texture is blending thoroughly.
- Add more water or broth if the soup feels too thick. You can easily adjust the consistency.
- Top with extras! Try adding roasted chestnuts, toasted breadcrumbs, or a swirl of vegan cream for a beautiful finish.
Vegan Serving Suggestions
This vegan cauliflower and chestnut soup pairs beautifully with:
- Crusty sourdough bread or baguette – Perfect for dipping into the creamy soup.
- Simple kale or green salad – Adds a refreshing contrast to the warm soup.
- Roasted vegetables – Carrots, parsnips, or sweet potatoes complement the nutty flavor.
- Vegan cheese toast – A crunchy, cheesy side for extra comfort.
- A drizzle of truffle oil – For a gourmet touch during the holidays.
This soup also makes an elegant starter for Christmas dinner or any cozy winter gathering.
Storing Instructions
If you have leftovers (which is rare because it’s that good!), here’s how to store your cauliflower and chestnut soup properly:
- Refrigerator: Store in an airtight container for up to 4 days.
- Freezer: Freeze in portions for up to 2 months. Thaw in the refrigerator overnight before reheating.
- Reheating: Warm gently on the stovetop over low heat. Add a splash of water or broth if it thickens too much.
This soup is perfect for meal prep — it actually tastes even better the next day as the flavors deepen.
