We recently served this for Thanksgiving and it just may become a tradition at Christmas as well. Even the Spiral House dogs, Sophie and Rocky, gobbled up their portions. The three secrets to this dish are Beyond Meat’s Beyond Beef product (a plant-based beef substitute), smoothly whipped mashed potatoes on top, and a generous drizzle of rosemary/shitake gravy made with lots of fresh rosemary.
Assemble the casserole a day ahead and refrigerate it if you like to make your holiday meal preparation that much easier. Then, all you need to do on the holiday itself is bake the shepherd’s pie for 45-60 minutes in a 350-degree Fahrenheit oven till bubbly. Pour some of the gravy on top when serving and place the remainder of the gravy in a bowl to the side of the casserole. (The Rosemary Mushroom Gravy was inspired by a recipe from the Catskill Animal Sanctuary’s Compassionate Cuisine program.)
