Ingredients

Instructions

  • Heat olive oil in a large pot over medium heat. Add fennel and onion; cook for 6-8 minutes until softened.
  • Stir in garlic, thyme, and red pepper flakes (if using), and cook for another minute.
  • Add the white beans, vegetable broth, salt, and black pepper. Bring to a gentle simmer and cook for 20-25 minutes.
  • Blend the soup until smooth using an immersion blender (or carefully in batches with a countertop blender).
  • Stir in lemon juice, adjust seasoning, and serve with a drizzle of olive oil and a sprinkle of lemon zest and fennel fronds.

Notes

  • If making ahead, add the lemon juice just before serving. The flavor is best when fresh and can lose its brightness if reheated.
  • For a variation, swap fennel for leeks for a slightly sweeter, milder flavor.
