Ingredients for Vegetarian Shepherd’s Pie

2 cups vegetable broth, divided
½ cup dry lentils
¼ cup pearl barley
1 teaspoon yeast extract spread (such as Marmite or Vegemite)
1 large carrot, diced
½ onion, finely chopped
½ cup walnuts, coarsely chopped
3 potatoes, chopped
1 teaspoon all-purpose flour
½ teaspoon water
Salt and ground black pepper to taste

Step-by-Step Vegetarian Shepherd’s Pie Instructions

Preheat your oven to 350°F (175°C).
Combine 1 ¼ cups vegetable broth, lentils, barley, and yeast extract in a large saucepan over medium heat. Let it simmer gently for about 30 minutes until the lentils and barley are tender.
In another saucepan, combine the remaining ¾ cup broth, diced carrots, chopped onion, and walnuts. Cook this over medium heat for 15 minutes or until the vegetables are softened.
Meanwhile, place chopped potatoes in a large pot, cover with salted water, and bring to a boil. Reduce the heat to medium-low and simmer until the potatoes are fork-tender, about 15 minutes. Drain and mash the potatoes.
In a small bowl, mix the flour and water until smooth. Stir this mixture into the carrot mixture, cooking until the sauce thickens.
Next, combine the carrot mixture with the lentil mixture. Stir to incorporate and season to taste with salt and pepper.
Transfer the vegetable-lentil mixture into a 2-quart casserole dish. Spread the mashed potatoes evenly over the top.
Place the dish in the oven and bake for 30 minutes, or until the mashed potatoes are lightly browned. Serve warm and enjoy!

Use homemade vegetable broth for maximum flavor.
Want creamier mashed potatoes? Add a splash of almond or oat milk during mashing.
Double the recipe and freeze one casserole for an easy meal later.
Let the pie rest for 5 minutes out of the oven before serving so it holds together better.
To get a crispy potato topping, brush the mashed potatoes with olive oil before baking.
Prep the filling a day in advance and assemble the dish when ready to bake.
Reheat leftovers in the oven at 350°F for 15-20 minutes to maintain the texture.
