Ingredients
For the sauce and filling:
- 3 tbsp olive oil
- 12 baby chestnut mushrooms, halved (or 5–6 regular mushrooms, sliced)
- 1 large onion, peeled and sliced
- 2 tbsp plain (all-purpose) flour
- 280 ml (1 cup + 3 tbsp) hot chicken stock (or water + 2 stock cubes)
- 200 ml (¾ cup + 1 tbsp) semi-skimmed or full-fat milk
- ½ tsp dried thyme (or 1 tsp fresh thyme leaves)
- 2 tbsp dry sherry (measure carefully to avoid overpowering the sauce)
- ¼ tsp salt
- ¼ tsp freshly ground black pepper
- 2 large cooked chicken breasts (about 250 g / 9 oz), chopped into bite-sized pieces
To serve:
- Chopped fresh parsley
- Boiled rice or pasta
Instructions
- Sauté the mushrooms:
Heat 1½ tbsp of oil in a large skillet over medium-high heat. Add the mushrooms and cook for 3–4 minutes until golden. Remove from the pan and set aside. - Cook the onions:
Add the remaining oil to the same pan. Sauté the sliced onion over medium-high heat for 5–6 minutes, stirring often, until softened and lightly browned on the edges. - Make the roux:
Stir in the flour and cook, stirring constantly, for 1 minute to remove the raw flour taste. - Add the stock:
Pour in a small amount of hot stock and whisk into the flour mixture to form a smooth paste. Gradually add the rest of the stock, whisking well after each addition to avoid lumps. - Add milk and seasonings:
Stir in the milk and thyme. Continue stirring as the sauce thickens over medium heat. Once thickened, add the sherry, salt, and pepper. Taste and adjust seasoning if necessary. - Finish with chicken and mushrooms:
Stir the cooked chicken and mushrooms into the sauce. Simmer for 2–3 minutes until heated through. - Serve:
Spoon over freshly cooked rice or pasta and garnish with chopped parsley.
Tips
- Use leftover roast chicken to save time.
- Whisk constantly when adding liquid to avoid lumps in the sauce.
- Don’t skip the sherry—just 2 tablespoons enhances the flavor without being overpowering.
- Mushrooms and onions should be nicely browned to deepen the overall flavor.

Variations and Substitutions
- Protein: Swap chicken for leftover turkey or rotisserie chicken.
- Vegetarian: Use sautéed mushrooms, peas, and bell peppers with vegetable stock.
- Creamier option: Use double cream or heavy cream in place of milk.
- No sherry? Substitute with white wine or leave it out for a more kid-friendly version.
