Ingredients

Instructions

  1. Step 1: Trim 200 g chicken thighs of skin and bone, then cut into 1 cm cubes. Melt 1 tbsp butter in a medium saucepan over medium heat. Add chicken and cook for 4-5 minutes until lightly browned on all sides.
  2. Step 2: Thinly slice 3 medium leeks (white and light green parts only) and add to the pot. Cook for 5 minutes until softened. Stir in 2 tbsp all-purpose flour and cook for 1 minute to eliminate raw flour taste.
  3. Step 3: Gradually whisk in 500 ml chicken stock, then bring to a gentle simmer. Cook uncovered for 20 minutes until chicken is fully cooked and leeks are tender.
  4. Step 4: Remove chicken and leeks with a slotted spoon, reserving the broth. Puree half the chicken mixture in a blender until smooth, then return to the pot.
  5. Step 5: Stir in 200 ml heavy cream and simmer for 5 minutes until lightly thickened and coats the back of a spoon. Season with 1/2 tsp salt and 1/4 tsp black pepper.
  6. Step 6: Return chicken and leeks to the pot and heat through for 2 minutes. Garnish with 1 tbsp fresh dill before serving.
