Ingredients

Have these measured and ready before you begin.

  • 500 g (17.6 oz) broccoli
  • 4 cups (960 ml) low-sodium vegetable broth
  • 1 tbsp olive oil
  • 1 tbsp butter
  • 1 tbsp all-purpose flour
  • 1.5 tsp fine salt
  • 1/2 tsp ground black pepper

Directions

1. Cut the broccoli into small florets and simmer it in the water until tender. Lift out the broccoli and reserve all the cooking liquid.

2. Heat the olive oil and butter in a deep pot. Add the flour and stir until fragrant and lightly colored.

3. Gradually whisk in the reserved broccoli liquid so no lumps form. Boil gently for 2–3 minutes.

4. Add the cooked broccoli and blend until smooth, taking care with the hot liquid.

5. Stir in the salt and black pepper, return to a brief simmer, and serve hot.
