Why This Recipe Works

To get the deep, robust flavor we were after for our steaks, we browned the onions (to bring out their natural sweetness) and the mushrooms (to deepen their inherent earthiness), and added flour as a thickener and a splash of sherry to deglaze the pan and complement the flavors of the onions and mushrooms. After hours in the slow cooker the steaks melded with the onions and mushrooms, turning fork-tender and rich-tasting. To finish the dish, we added a bit of cream to round out the flavors, and some parsley for freshness.
