This sauce is the boss for filet, pasta, or even chicken. Fish would be crazy.
Ingredients
- 2Lb mushrooms, sliced
- 2 onions
- 1 cup heavy cream
- 3 tsp Coarse cracked Peppercorn
- 3 tbsp Dijon mustard
- 3 tsp Worcestershire sauce
- Fun splashes of Hennessy
- 2 cups beef stock
- 5 Tbsp butter
- Optional: fresh thyme sprigs
- Salt to taste
Instructions
- 1. Prep the base: In a large skillet over medium heat, melt the butter. Add the chopped onion (or shallots) and sauté for 3-4 minutes until softened and starting to turn golden.
- 2. Cook the mushrooms: Add the sliced mushrooms and a pinch of salt. Cook for 5-7 minutes, stirring occasionally, until the mushrooms release their liquid and brown nicely. The onions should be caramelized and soft by now.
- 3. Build flavor: Stir in the minced garlic and cracked peppercorns. Cook for 1 minute until fragrant (toasting the peppercorns gently blooms their flavor without burning).
- 4. Deglaze: If using brandy/cognac, pour it in (remove pan from heat first if flambéing for safety—light it carefully in a ladle or just let it simmer). Scrape up any browned bits from the pan bottom. Let it reduce by half (2-3 minutes).
- 5. Add liquids: Pour in the beef stock (and Worcestershire if using). Bring to a simmer and reduce by about half (4-5 minutes) to concentrate the flavors.
- 6. Finish creamy: Stir in the heavy cream and Dijon mustard. Lower heat to medium-low and simmer gently for 5-8 minutes, stirring occasionally, until the sauce thickens to a luscious, coating consistency (it should coat the back of a spoon). If it gets too thick, add a splash more stock or cream. Taste and adjust salt/pepper.
- 7. Serve: Spoon generously over rested, seared filet mignon. Garnish with extra cracked pepper or fresh thyme if desired.
- 8. Tips for Perfection
- 9. • Use coarsely cracked peppercorns (mortar/pestle or crush under a pan) for the best texture and bite—pre-ground won’t give the same punch.
- 10. • For extra richness, make the sauce in the same pan after searing your filets (use those fond/browned bits!).
- 11. • If you want it thicker without more reduction, mix ½ tsp cornstarch with a little cold stock and stir in at the end.
- 12. • Pairs amazingly with mashed potatoes, roasted veggies, or a simple green salad.
