Tips & Variations

  • Use boneless chicken thighs for quicker cooking and easier serving.
  • Try swapping the new potatoes for sweet potatoes for a twist in flavor.
  • Frozen mixed vegetables can be added along with the peas for extra color and nutrition.
  • If you prefer a thicker sauce, stir in a little extra flour or reduce the liquid by simmering uncovered longer.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave until piping hot, adding a splash of water if the sauce has thickened too much.

FAQs

Can I use chicken breasts instead of thighs?

Yes, chicken breasts can be used but they may cook faster and can dry out if overcooked. Adjust timing accordingly and consider adding them partway through cooking.

Is it possible to make this recipe in advance?

Absolutely. Prepare the casserole up to the point before adding the peas, then cool and refrigerate. When ready to eat, reheat gently and add the peas during the final cooking stage.

Ingredients

Scale

Chicken

  • 8 bone-in chicken thighs, skin removed
  • 1 tbsp oil

Vegetables

  • 5 spring onions, sliced (whites and greens separated)
  • 2 large carrots, cut into batons (no need to peel)
  • 400g new potatoes, halved if large
  • 200g frozen peas

Other Ingredients

  • 2 tbsp plain flour
  • 2 chicken stock cubes
  • 1 tbsp grainy mustard
  • Small handful fresh soft herbs (parsley, chives, dill or tarragon), chopped
  • 750ml hot water

Instructions

  1. Brown the chicken: Heat the oil in a casserole or wide pan with a lid over medium heat. Add the chicken thighs (skin removed) and fry until browned on all sides, sealing in the juices and developing flavor.
  2. Add spring onion whites and flour: Stir in the whites of the spring onions along with the plain flour and chicken stock cubes. Cook for a few minutes, stirring constantly, until the flour is fully absorbed and the mixture thickens slightly.
  3. Add hot water and vegetables: Gradually pour in 750ml of hot water from the kettle, stirring continuously to create a smooth sauce. Add the carrot batons and new potatoes. Bring the mixture to a gentle simmer.
  4. Simmer covered: Cover the pan with a lid and cook for 20 minutes to allow the chicken and vegetables to cook through and flavors to meld.
  5. Simmer uncovered: Remove the lid and continue to simmer for another 15 minutes to reduce the sauce slightly and further tenderize the ingredients.
  6. Add peas and finish cooking: Stir in the frozen peas and cook for an additional 5 minutes until heated through.
  7. Season and garnish: Remove from heat and stir in the grainy mustard, green parts of the spring onions, and chopped fresh herbs. Season with salt and pepper to taste.

Notes
