Step 1

Melt the butter in a large saucepan over medium-high heat. Cook and stir the mushrooms, onion and garlic in the butter until tender. Reserving the liquid in the saucepan, remove the mushroom mixture to a bowl. Return the butter mixture to medium-high heat.

Step 2

Whisk together the flour and half-and-half until smooth; set aside.

Step 3

Season the beef with salt and pepper; cook the beef in the reserved liquid until browned, about 5 minutes. Stir the wine, beef bouillon, thyme, basil, oregano, bay leaves, and pepper; reduce heat to medium-low and simmer 10 minutes. Slowly stir in the flour mixture and simmer, stirring occasionally, until the sauce thickens, 20 to 30 minutes. Add the mushroom mixture and stir.
