🛒 Ingredients

8 servings

8
  • 1 kg (2.2 lbs) chicken breast fillets
  • 1 kg (2.2 lbs) small potatoes
  • 4 garlic cloves, minced
  • Juice of 1 lemon
  • Salt and freshly ground black pepper
  • 50 g (3½ tbsp) unsalted butter
  • 200 ml (¾ cup) heavy cream
  • 3 tablespoons Dijon mustard
  • 1 chicken stock cube
  • Fresh parsley, chopped, to serve

Directions

  1. 1

    Season the chicken fillets with garlic, lemon juice, salt, and pepper. Set aside to marinate for 15 minutes.

  2. 2

    Parboil the small potatoes in salted water for about 12 minutes until just tender. Drain and set aside.

  3. 3

    Melt the butter in a large skillet over medium-high heat. Sear the chicken fillets for 5–6 minutes per side until golden brown and cooked through. Remove and set aside.

  4. 4

    In the same pan, fry the parboiled potatoes in the remaining butter until crispy and golden all over.

  5. 5

    In a small saucepan, whisk together the heavy cream, Dijon mustard, and crumbled stock cube over low heat. Stir until the sauce just begins to simmer, then remove from heat.

  6. 6

    Return the chicken to the pan alongside the potatoes, pour the mustard cream sauce over everything, and serve immediately garnished with fresh parsley.

💡 Chef's Tip

Use whole-grain mustard for a more rustic texture and bolder flavour. A splash of dry white wine added to the pan before the cream makes the sauce even more aromatic.
