This creamy mushroom sauce is rich, flavorful, and made with shallots, white wine, thyme, and double cream. Perfect for serving over steak, chicken, or roasted vegetables, it’s quick to prepare and packed with savory depth from sautéed chestnut mushrooms and garlic.

Ingredients

• 1 tbsp (15g) unsalted butter
• ½ tbsp sunflower oil (or use the pan juices from cooked steak for extra flavor)
• 2 shallots, finely chopped
• 8 chestnut mushrooms, sliced
• 2 garlic cloves, minced
• ½ tsp salt
• ½ tsp ground black pepper
• ¼ tsp dried thyme (or 2 sprigs of fresh thyme)
• 120 ml (½ cup) white wine
• 120 ml (½ cup) chicken stock
• 180 ml (¾ cup) double (heavy) cream

Instructions

1. Heat the pan:
   Add the butter and oil to a frying pan over medium heat. If you’ve just cooked steak, use the leftover meat drippings instead of butter and oil for extra richness.
2. Sauté the shallots:
   Once the butter has melted, add the shallots and cook for 2–3 minutes until slightly softened.
3. Add the mushrooms:
   Stir in the mushrooms, garlic, salt, pepper, and thyme. Cook for about 3 minutes until the mushrooms start to soften and release their juices.
4. Deglaze with wine:
   Pour in the white wine and increase the heat to high. Let it boil, then reduce and simmer until most of the liquid has evaporated — about 5 minutes.
5. Finish the sauce:
   Stir in the chicken stock and cream. Simmer gently for another 2–3 minutes until warmed through. Add any resting juices from the steak if available. Remove from heat.
6. Serve immediately:
   Spoon the sauce generously over steak or your preferred main dish.

Tips

• For deeper flavor, use pan drippings from steak or roast chicken.
• Slice mushrooms evenly for consistent cooking.
• Simmer the wine fully to remove its sharpness and concentrate the flavor.

Variations and Substitutions

• No wine? Use a splash of extra chicken stock with a teaspoon of white wine vinegar or lemon juice.
• Vegetarian version: Swap chicken stock for vegetable stock.
• No shallots? Use half a small onion as a substitute.
• Creamier texture: Stir in a teaspoon of cream cheese at the end for extra richness.
