Chefs Tip
Make this recipe vegetarian by swapping out the beef stock for vegetable stock and using a vegetarian wine. Replace the white wine with red wine for a rich alternative.

The optimum time and temperature varies by individual ovens – these are guidelines only. Please ensure all cooked recipes are served piping hot. Keep raw meat separate from cooked food. Use separate kitchen utensils and surfaces for raw and cooked foods, or wash thoroughly in between use. Wash hands after handling raw meat.
