About the Recipe

Lentil shepherd’s pie offers a delicious plant-based twist on traditional cottage pie, sure to please the whole family. Shepherd’s pie is the ultimate comfort food and a wonderful vegetarian main dish to enjoy as a holiday entree or delicious meal any time of year.

If you’ve never tried making shepherd’s pie, fear not; the process may seem complicated, but it’s surprisingly simple and uses simple, everyday ingredients.

You’ll begin by cooking the lentils until tender, then boiling and mashing the potatoes, and preparing the rest of the vegetables for the filling.

The savory lentil mixture and creamy mashed potatoes are layered in a dish and baked until you have a gravy-like filling with rich flavors topped with lightly browned, crisp-on-top creamy mashed potatoes.

This dish makes an ideal addition to your holiday table, especially if you have vegan or vegetarian guests. Packed with fiber and protein from the lentils, it offers a healthy alternative to the traditional ground beef version.

For more hearty vegetarian mains, this Vegan Pot Pie, Chickpea Meatloaf, Vegan Sloppy Joes and Nut Roast are all excellent too.

I really like using lentils as an alternative to ground meat. You can also try them in this Slow Cooker Red Lentil Chili and these Vegan Lentil Tacos.
