Ingredients
 
 

  • 4 Chicken Breasts - skinless and boneless
  • Sea Salt and Black Pepper
  • 1 tbsp Olive Oil
  • 1 tbsp Butter
  • 2 large Leeks - trimmed, halved, and thinly sliced
  • 2 cloves Garlic - minced
  • ¼ cup White Wine - optional
  • 1½ cups Chicken Stock
  • ⅓ cup Heavy Cream (Double Cream)
  • 1 tbsp Dijon Mustard
  • 1 tsp Wholegrain Mustard
  • Fresh Parsley - chopped, for garnish

Instructions
 

  • Season the chicken breasts generously with salt and pepper.
  • Heat the olive oil and butter in a large skillet or sauté pan over medium-high heat.
  • Sear chicken for 4 minutes per side until golden brown but not cooked through. Remove from the pan and set aside on a plate.
  • Reduce heat to medium. Add the sliced leeks with a pinch of salt and cook for around 6 minutes until soft, scraping up any brown bits.
  • Add the minced garlic and stir in for 30 seconds.
  • If using, add in the wine and let the alcohol bubble and reduce for a minute or so.
  • Pour in the chicken stock and stir in the Dijon and wholegrain mustard.
  • Nestle the chicken breasts back into the pan.
  • Simmer gently for 8 to 10 minutes until cooked through and the sauce has thickened slightly.
  • Stir in the cream. Taste and adjust seasoning if needed.
  • Finish with the chopped fresh parsley and serve straight from the pan.
