Plant-Based Shepherd’s Pie

Instructions

1. To make the potato layer: Place the potatoes, garlic, and vegetable stock in a large saucepan and bring to a boil over high heat. Reduce the heat to medium and simmer for about 15 minutes, or until the potatoes are tender. Drain the potatoes, reserving the cooking water. Return the potatoes to the pot, cover, and keep over low heat, shaking periodically, for about 5 minutes or until dry.
   
   Add the almond milk, mustard, thyme, and pepper. Mash until only a few small lumps of potato are left. Season with salt.
2. To make the mushroom and gravy layer: Add 1 cup of reserved potato liquid and the onion to a large saucepan and bring to a boil over high heat. Reduce the heat to medium and simmer for 5 minutes. Add the mushrooms, thyme, and tarragon and simmer for another 10 minutes, or until all the liquid is reduced. Add the grape juice to deglaze the pan and cook until mostly reduced, about 5 minutes.
   
   Combine the brown rice flour, an additional 2 cups of reserved potato liquid, and the mustard in a medium bowl and whisk until smooth. Pour into the pan and cook, stirring constantly until it thickens. Remove from the heat. Stir in the soy sauce, maple syrup, and pepper.
3. To make the tomato layer: Add the tomatoes, onion, garlic, oregano, basil, peas, and carrots to a large saucepan and sauté for 10 minutes. Add the cauliflower and green beans and cook for another 5 minutes. Drain any excess water and season with salt.
4. To assemble the casserole: Preheat the oven to 350ºF. Spread the tomato layer in the bottom of a 9 x 13-inch baking dish. Pour the mushroom and gravy layer over the tomato layer. Spread the potato layer over the mushroom layer.
   
   Cover the dish with a lid or aluminum foil and bake for 30 minutes. Remove the cover and broil for 10 minutes, or until bits of the potato layer turn golden brown.
   
   Chef's Notes:
   
   I’ve used different types of potatoes for this recipe and I’ve found that Yukon Gold potatoes yield the most flavor and the creamiest texture. If Yukon Golds are not available, use any medium- to high-starch potato. Be sure to not over-mash the potatoes, which will create a gummy consistency.
   
   If you can find the San Marzano crushed tomatoes that come in a glass jar, use them instead of canned. The tomato sauce layer has to be thick, or the potato layer will sink into the dish.
   
   If you want to vary the vegetables, try this dish with zucchini, parsnips, or eggplant.
   
   Save any extra sauce and gravy that will not fit into the dish and keep it on hand for serving reheated leftovers.
