This creamy, rich, earthy, and strongly umami flavoured Marsala Mushroom Sauce is a perfect compliment to my Individual Ground Beef Wellingtons recipe.This Marsala wine sauce is made with beef stock, cremini mushrooms and will elevate any casual meal into an elegant entrée!
Melt the butter in a large sauté pan over medium high heat. Add the mushrooms and thyme then sauté for 3-4 minutes. Sprinkle the flour over the pan and stir until it is mixed well into the mushroom and butter.
Add the Marsala and cook for 1 minute stirring frequently. Add the beef stock and bring to the boil.
Reduce heat and simmer for around 5-8 minutes until sauce has thickened, stirring regularly.
