  • 2 tbsp butter
  • 1/2 onion medium
  • 2 cups/ 200g chestnut mushrooms
  • 1 clove garlic
  • 2 tbsp cognac or brandy
  • 1 cup/250ml heavy cream/double cream
  • 2 tbsp creme fraiche optional
  • salt to taste
  • pepper to taste
  • 1 tsp flat leaf parsley chopped


  • In a small skillet melt the butter and add sliced mushrooms with a pinch of salt, brown over medium heat to get some colour on them. (If mushrooms release too much liquid and are steaming instead of browning, turn up the heat.)
  • Once mushrooms are browned turned the heat to low and add finely chopped onions, (add 1 tbsp of butter if the skillet is too dry) and cook the onions for 10 minutes until they are limp and translucent, stir once in a while to prevent burning. (Don't rush this step, it's important that the onions are fully cooked.) Then add minced garlic and stir fry for 30 seconds. 
  • Pour in cognac or brandy and let it bubble for 1-2 minutes, then add cream, creme fraiche if using, salt, pepper and chopped parsley, stir and let it simmer for a few minutes. Taste and adjust seasoning if needed. 
    Serve with steak, chicken, pork chops or roasted vegetables.
