Lentil and Vegetable Shepherd's Pie

Shepherd's pie started life in the British countryside as a way to use up leftover roast lamb under a blanket of mashed potato. The idea of a savory filling with a fluffy top is much older than that, though, and it travels well. This version keeps the spirit of the original and swaps the meat for brown lentils, which cook up soft and earthy and take on the flavor of the vegetables around them.

Lentils are one of those pantry staples that do more than people expect. They are a plant protein and a good source of fiber, and they hold their shape in a long simmer, which is why they work so well in a pie that needs to be sliced and served. Brown lentils are the right choice here because they stay firm enough to give the filling some bite. Red lentils would break down into mush.

The topping is the part that surprises people. You beat a portion of the cooked lentils with almond milk, salt, and parsley until they turn almost like mashed potatoes. It spreads easily, and in the oven the top dries out and browns at the edges. Let it rest for ten minutes before you cut into it, or the filling will run across the plate. Mushrooms are worth cooking until every bit of their liquid has gone, because that concentrated, meaty flavor is what makes the pie feel hearty rather than soupy.

For leftovers, this pie keeps well in the fridge for three or four days, covered tightly. Reheat individual portions in a skillet with a splash of stock, or warm the whole dish, covered with foil, in a 350 degree oven until hot through. It also freezes nicely in single servings. The lentil topping holds up better than mashed potato does after thawing, so this is an easy make-ahead dinner for a busy week.

What to serve alongside? A simple green side cuts through the richness. Golden Roasted Cauliflower with Lemon Dressing is a good match, since the lemon brightens the earthy filling. If you want something closer to the pie's comfort-food roots, Rustic Red Potatoes and Green Beans on One Sheet Pan gives you another tray to roast while the pie bakes. For a sweet finish that is light and fruity, Almond Butter Stuffed Baked Apples pairs nicely with the almond milk in the topping.

Two small notes from my own kitchen. Dice the carrots and celery small so they cook through at the same pace as the lentils. And if your lentils have soaked up all their cooking liquid, add a spoonful of stock to the vegetables rather than more almond milk, so the flavor stays savory.
