  • Pour in vegetable broth until vegetables are just covered.
  • Simmer
  • Bring to a boil, then reduce heat and simmer 20–25 minutes until cauliflower is fork-tender.
  • Blend
  • Use an immersion blender to puree until smooth (or carefully blend in batches).

  • Serve
  • Let rest 5 minutes before serving.
  • Garnish with fennel fronds, olive oil drizzle, cracked pepper, or red pepper flakes.

Notes

  • Cook cauliflower until very soft for ultra-smooth texture.
  • Add broth gradually to control thickness.
  • Lemon juice balances fennel’s natural sweetness.
  • Soup thickens as it cools—add broth when reheating if needed.
  • Flavor improves after a day in the refrigerator.
