Reduce heat to medium-high and using the same skillet, add the remaining 2 tablespoons of butter. Add the mushrooms and cook without stirring for 3 minutes. Season the mushrooms with ½ teaspoon salt and ¼ teaspoon black pepper; stir and continue to cook for 2 minutes. Add the shallots and cook for 2 minutes. Add the garlic and cook for 20 seconds, making sure that the garlic does not burn. Add the brandy and cook until most of the liquid is almost evaporated, about 15 seconds. Add broth, cream, Dijon, Worcestershire sauce and lemon juice; cook, stirring often, until sauce reduces slightly, about 3 minutes. Stir in parsley and season to taste with salt and black pepper, if needed. Remove from heat.
