Method
Melt 20g of the butter in a sauté pan over medium-high heat (190°C/375°F).
Add the sliced mushrooms in a single layer. Cook without stirring for 2 minutes to develop a sear, then toss and continue cooking until deep golden brown and their liquid has evaporated.
Reduce heat to medium. Add the minced shallot and garlic. Cook, stirring constantly, until the shallots are softened and translucent.
Sprinkle the flour over the mushroom mixture and stir in the tomato paste. Cook for one minute to remove the raw flour flavor and lightly caramelize the tomato paste.
Pour in the dry white wine to deglaze the pan. Use a wooden spoon to scrape up any browned bits stuck to the bottom. Let the wine simmer until it has almost completely evaporated.
Slowly whisk in the beef broth to prevent lumps from forming. Add the canned crushed tomatoes and fresh thyme. Bring the mixture to a gentle simmer, then reduce heat to medium-low. Simmer until the sauce is reduced, thick, and coats the back of a spoon.
Remove the pan from the heat. Stir in the remaining 10g of cold butter and the chopped parsley until the butter is fully melted and emulsified into the sauce. Season with salt and black pepper to taste.
Chef's Notes
- For the deepest flavor, do not crowd the mushrooms in the pan. They need space to sear and caramelize rather than steam.
- A high-quality, dry white wine like Sauvignon Blanc or unoaked Chardonnay provides the necessary acidic balance to cut through the rich beef broth.
- Mounting the finished sauce with a small extra knob of cold butter off the heat (monter au beurre) gives it a beautiful, restaurant-quality gloss and velvety mouthfeel.
- If using store-bought beef broth, opt for a low-sodium variety. As the sauce reduces, the salt concentration increases significantly, which can easily ruin the balance of the final dish.
- This sauce pairs exceptionally well with a reverse-seared steak, roasted chicken, or even poured over a bed of buttery egg noodles for a rustic vegetarian-friendly option.
Storage
Refrigerator: 4 days — Store in an airtight container. The sauce may thicken when chilled; thin with a splash of broth when reheating.
Freezer: 3 months — Freeze in ice cube trays for easy portioning.
Reheating: Warm gently in a saucepan over low heat, whisking constantly until smooth.
