Creamy Onion Cauliflower Soup (Print Version)

Velvety blend of onions and cauliflower for a comforting, light, low-carb dish with subtle seasoning.

# What You'll Need:

→ Vegetables

01 - 1 medium head cauliflower (about 21 oz), cut into florets
02 - 2 large yellow onions, sliced
03 - 2 cloves garlic, minced
04 - 1 stalk celery, chopped

→ Liquids

05 - 4 cups low-sodium vegetable broth
06 - 1 cup unsweetened almond milk or heavy cream

→ Fats and Seasonings

07 - 2 tablespoons olive oil or unsalted butter
08 - 1/2 teaspoon sea salt, plus more to taste
09 - 1/4 teaspoon ground white or black pepper
10 - Pinch of freshly grated nutmeg

→ Garnish

11 - Chopped fresh chives or parsley
12 - Swirl of heavy cream or olive oil

# How to Make:

01 - Heat olive oil or butter in a large pot over medium heat. Add sliced onions and chopped celery. Sauté for 8 to 10 minutes until onions are soft and translucent.
02 - Add minced garlic and cook for 1 minute until fragrant.
03 - Add cauliflower florets to the pot and sauté for 2 minutes, stirring occasionally.
04 - Pour in vegetable broth and bring to a boil. Reduce heat, cover the pot, and simmer for 20 minutes until cauliflower is very tender.
05 - Remove from heat. Use an immersion blender to puree the soup until smooth and creamy. Alternatively, carefully transfer soup in batches to a countertop blender and blend until desired consistency is reached.
06 - Stir in almond milk or heavy cream, salt, pepper, and nutmeg. Warm gently over low heat without boiling. Adjust seasoning to taste.
07 - Ladle into bowls and serve hot, garnished with fresh chives, parsley, or a swirl of cream as desired.

# Expert Advice:

01 -
  • It tastes indulgent and creamy without requiring a single drop of heavy cream unless you choose richness.
  • The whole thing comes together in under an hour, making it perfect for those moments when you need comfort food without the fuss.
  • Cauliflower becomes something entirely different here—sweet, tender, and so mild it almost disappears into the silky broth.
02 -
  • Don't skip the slow sautéing of onions at the beginning—those caramelized flavors are what make this soup taste rich despite being simple.
  • The soup thickens as it sits, so make it slightly looser than you think you want it; you can always thin it with more broth when reheating.
03 -
  • Use the vegetables' natural sweetness by taking time at the beginning—rushing the onion sauté will cost you the depth that makes this soup special.
  • Taste constantly as you season so the soup becomes exactly what you want rather than what the recipe dictates, because your palate is the real guide here.
