Ingredients

Scale

Chicken Marinade

  • 2 chicken breasts (sliced in half lengthways)
  • 2 garlic cloves (minced)
  • 1 tsp Dijon mustard
  • 1 tbsp vegetable oil
  • Pinch of flaky salt
  • Grinding of black pepper

Sauce and Cooking

  • 1/2 tbsp vegetable oil
  • 3 shallots (finely sliced)
  • 4 garlic cloves (finely sliced)
  • 300 ml chicken stock (made with 1/2 chicken stock cube and 300 ml water)
  • 1 heaped tsp Dijon mustard
  • 1 heaped tsp wholegrain mustard
  • 1 tsp mixed herbs (or dried thyme)
  • 300 ml cream (single or light)
  • Salt and pepper to taste

Mashed Potatoes

  • 400 g large potatoes (russet or Maris Piper, chopped into small pieces)
  • 20 g salted butter
  • 100 ml milk
  • 10 g chives (finely chopped)

Instructions

  1. Marinate the Chicken: In a bowl, combine 1 tsp Dijon mustard, 2 minced garlic cloves, 1 tbsp vegetable oil, a pinch of flaky salt, and freshly ground black pepper. Stir well to mix. Add the chicken breasts and coat them evenly with the marinade. Let them marinate for at least 10 minutes or cover and refrigerate overnight for deeper flavor.
  2. Sear the Chicken: Heat a skillet or frying pan over medium heat and drizzle with 1/2 tbsp vegetable oil. When hot, add the marinated chicken breasts. Fry each side for about 3 minutes until browned but not fully cooked through. Remove the chicken from the pan and set aside.
  3. Sauté Shallots and Garlic: Using the same pan, add a little more vegetable oil if needed, then add the finely sliced shallots. Stir fry for about 15 minutes until they become soft and aromatic. Add the finely sliced garlic cloves and cook for another 2 minutes.
  4. Make the Sauce and Simmer Chicken: Pour in the chicken stock, then stir in 1 heaped tsp wholegrain mustard, 1 heaped tsp Dijon mustard, and 1 tsp mixed herbs. Add 300 ml cream and season with salt and pepper. Stir everything together, then nestle the seared chicken breasts into the sauce. Bring to a boil, then reduce the heat to a simmer and cover with a lid. Cook for 10 minutes until the chicken is fully cooked and the sauce has thickened.
  5. Prepare Mashed Potatoes: While the chicken simmers, boil the chopped potatoes in salted water until tender, about 10-15 minutes. Drain the potatoes thoroughly and return them to the pot. Add 20 g salted butter and 100 ml milk. Use a hand blender or masher to mash until smooth and creamy. Season with salt and pepper to taste.
  6. Serve: Divide the mashed potatoes between two plates. Place the Dijon mustard chicken breasts on top, spoon over the creamy sauce, and garnish with finely chopped chives. Serve immediately and enjoy!

Notes

  • Marinating the chicken overnight enhances flavor but a minimum of 10 minutes works well for a quick meal.
  • Use light or single cream to keep the sauce creamy without it being too rich.
  • Russet or Maris Piper potatoes work best for smooth, fluffy mashed potatoes.
  • If you prefer a thicker sauce, simmer uncovered for a few more minutes to reduce.
  • Adjust seasoning in the sauce and mashed potatoes according to taste preferences.
