    For the Mushroom Cream Sauce: Heat olive oil in a large sauté pan over medium heat. Add sliced onions, being careful not to crowd the pan and sauté until softened and lightly browned. Add garlic and sauté 1 minute more. Add the white wine and chicken stock to the mushrooms and bring to a simmer. Simmer for 5-7 minutes then reduce the heat and stir in the cream. Season to taste with salt and pepper. Remove from heat and set aside.

    Transfer steaks to a platter and cover with foil. Let rest for 10 minutes before removing the foil and carving into thin slices.
