Description

This Creamy Chicken and Mushroom One-Pan Casserole is a comforting and flavorful dish made with tender chicken thighs, earthy mushrooms, and a rich, creamy sauce. Perfect for a cozy dinner with minimal cleanup.


Ingredients

  • 1 tbsp olive oil
  • 8 skin-on, bone-in chicken thighs
  • 1/2 tsp salt
  • 1/2 tsp pepper
  • 1 tbsp unsalted butter
  • 1 large onion, finely chopped
  • 3 cloves garlic, minced
  • 250g (8.8 oz) chestnut mushrooms, sliced
  • 1 tbsp plain (all-purpose) flour
  • 120ml (1/2 cup) dry white wine
  • 480ml (2 cups) chicken stock
  • 120ml (1/2 cup) double (heavy) cream
  • 1 tsp dried thyme
  • Fresh parsley, chopped (to serve)

Instructions

  1. Preheat the oven to 180C/350F (fan).
  2. Heat the olive oil in a large oven-proof pan or casserole dish over medium-high heat.
  3. Season the chicken thighs with salt and pepper, then place them skin-side down in the pan. Brown for 5-6 minutes, then flip and brown the other side for 2-3 minutes. Remove from the pan and set aside.
  4. Add the butter to the pan, followed by the chopped onion. Cook for 5 minutes until softened.
  5. Stir in the garlic and cook for 1 minute, then add the mushrooms and cook for another 5 minutes.
  6. Sprinkle in the flour and stir well, cooking for 1 minute to eliminate the raw taste.
  7. Pour in the wine, stir and allow to simmer for 2-3 minutes.
  8. Add the chicken stock, cream, and thyme. Stir and bring to a gentle simmer.
  9. Place the browned chicken thighs back into the pan, skin-side up, and spoon a little sauce over each one.
  10. Transfer the pan to the oven and bake for 30-35 minutes, until the chicken is cooked through and the sauce is thickened.
  11. Sprinkle with chopped parsley before serving.

Notes

  • Use skinless chicken if you prefer a lighter dish, though skin-on adds more flavor.
  • Serve with mashed potatoes, rice, or crusty bread to soak up the sauce.
  • You can substitute the wine with more chicken stock if preferred.
  • This dish can be made ahead and reheated gently on the stovetop.
