In a large frying pan over medium heat, melt butter with olive oil. Add shallots and cook 2–3 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.
Add sliced mushrooms and sauté 4–5 minutes until softened and lightly golden.
Stir in Dijon mustard and Worcestershire sauce, mixing well.
Carefully pour in the brandy (or cognac), scraping up any browned bits from the pan. Let simmer 1–2 minutes to reduce slightly.
Add beef stock and simmer 2–3 minutes. Stir in heavy cream and let the sauce gently simmer until slightly thickened, about 3–5 minutes.
Season with salt and black pepper to taste. Spoon generously over cooked steak and garnish with fresh parsley.
Melissa's Notes
If you want a thicker sauce, let it reduce a little longer before serving. A splash more brandy at the end adds a bold finishing touch. This sauce is also excellent served over creamy mashed potatoes.
