Ingredients
- 1 tbsp olive oil
- 1 large onion, finely chopped
- 3 thyme sprigs, leaves picked
- 2 garlic cloves, crushed
- 350g chicken breasts, cut into small chunks
- 250g chestnut mushrooms, sliced
- 300ml chicken stock
- 100g crème fraîche
- 1 tbsp wholegrain mustard
- 100g kale
- 2 tsp cornflour, mixed with 1 tbsp cold water
- 375g pack puff pastry, rolled into a circle slightly bigger than your dish

Instructions
- Step 1: Heat 1/2 tbsp olive oil over a gentle heat in a flameproof casserole dish. Add the chopped onion and cook for 5 minutes until softening. Scatter over the thyme leaves and crushed garlic, stirring for 1 minute.
- Step 2: Turn up the heat and add the chicken chunks, frying until golden but not fully cooked. Then add the sliced mushrooms and the remaining 1/2 tbsp of olive oil.
- Step 3: Preheat your oven to 200°C (180°C fan)/gas mark 6.
- Step 4: Pour in the chicken stock, then stir in the crème fraîche, wholegrain mustard, and kale. Season well with salt and pepper.
- Step 5: Add the cornflour mixture to the dish and stir until the sauce thickens slightly. Remove the casserole from the heat.
- Step 6: Cover the filling with the puff pastry, pressing the edges into the sides of the casserole dish. Slice a small cross in the center of the pastry to allow steam to escape, then brush the pastry with the egg yolk to glaze.
- Step 7: Bake in the preheated oven for 30 minutes, or until the pastry is puffed up and golden brown. Serve warm.
Tips & Variations

- Ensure the cornflour is well mixed with cold water to prevent lumps in the sauce.
