Step 1: Brown the chicken
- Heat the olive oil in a large frying pan over medium heat. Season the chicken breasts with salt and pepper. Brown the chicken, skin-side down, for 5-6 minutes until the skin is golden and crispy. Turn the chicken over and cook for another 4-5 minutes on the other side. Remove the chicken from the pan and set aside.
Step 2: Sauté the onion and garlic
- In the same pan, add the butter and sauté the finely chopped onion and minced garlic over medium heat for 5-7 minutes until softened and fragrant.
Step 3: Deglaze with white wine
- Pour the white wine into the pan, stirring to deglaze any browned bits from the bottom. Let the wine simmer for 3-4 minutes to reduce slightly.
Step 4: Make the creamy sauce
- Stir in the chicken stock and Dijon mustard, allowing the mixture to simmer for 2-3 minutes. Then, pour in the double cream and continue to simmer the sauce for 5-7 minutes until it thickens slightly.
Step 5: Finish cooking the chicken
- Return the browned chicken breasts to the pan, nestling them into the sauce. Simmer gently for 10-12 minutes, or until the chicken is cooked through and the sauce has thickened.
Step 6: Garnish and serve
- Once the chicken is fully cooked, garnish with fresh parsley (optional) and serve the Mary Berry Chicken Supreme with your choice of sides.
