Ingredients:
- 3 Tbsp unsalted butter (plus a knob for finishing)
- 2 large shallots, finely minced
- 2 cloves garlic, minced
- 1 tsp fresh thyme leaves
- 1 lb assorted mushrooms (Cremini, Shiitake), sliced thickly
- 2 Tbsp all-purpose flour
- 1/2 cup dry white wine (e.g., Pinot Grigio)
- 1 1/2 cups low-sodium chicken or vegetable stock (warmed)
- 3/4 cup heavy cream (35% fat)
- 2 Tbsp fresh parsley, chopped
- Salt and freshly ground black pepper to taste
Instructions:
- Melt 2 Tbsp of butter in a large, heavy-bottomed skillet over medium-high heat. Add the sliced mushrooms (in batches if necessary) and cook, undisturbed, until deeply browned and caramelised. Remove mushrooms from the pan and set aside.
- Reduce heat to medium. Add the remaining 1 Tbsp of butter. Sauté the minced shallots until softened and translucent (about 3-4 minutes). Add the garlic and thyme; cook for 1 minute until fragrant.
- Sprinkle the flour over the shallot mixture. Stir constantly for 1-2 minutes to cook out the raw flour taste, creating a light roux.
- Slowly pour in the white wine, scraping up any browned bits (fond) from the bottom of the pan. Let the wine bubble and reduce by half.
- Gradually whisk in the warm stock until the mixture is completely smooth. Bring the sauce to a gentle simmer and cook, stirring occasionally, for 5-7 minutes until it lightly coats the back of a spoon.
- Lower the heat to low. Stir in the heavy cream until the sauce is uniform. Return the sautéed mushrooms to the pan and gently warm through for 2 minutes (do not boil).
- Stir in the final knob of cold butter for shine and richness. Taste and season generously with salt and freshly cracked black pepper. Stir in fresh parsley just before serving.
