Best Plant-Based Lentil Shepherd's Pie - Easy 50-Minute

This plant-based shepherd's pie came out of a cold evening when I wanted comfort food but had no meat in the house. Lentils and mushrooms make a filling that's just as hearty as the classic. The mashed potato top gets golden and crisp at the edges, and the gravy underneath is rich and savory.

You don't need any fancy equipment or hard-to-find ingredients. Most of what's in here is probably in your pantry right now. It's the kind of meal that makes you forget it's meatless.

I like to serve it straight from the baking dish, with a simple green salad on the side. Leftovers taste even better the next day, if there are any.

About the Ingredients

1 cup (200g) dried brown or green lentils, rinsed

Brown or green lentils hold their shape when baked. Red lentils turn mushy, so avoid them here.

2 tablespoons olive oil

Any neutral oil works, like canola or avocado. You can use water or veggie broth to sauté if you're oil-free.

1 large yellow onion, diced

About 1.5 cups. A sweet onion works too.

2 carrots, peeled and diced

About 1 cup. No need to be precise – just small, even pieces.

2 celery stalks, diced

About 1 cup. Adds that classic savory base.

8 oz (225g) cremini mushrooms, sliced

Button mushrooms are fine. For more umami, try a handful of dried porcini soaked in hot water, then chopped.

3 cloves garlic, minced

Fresh is best, but a teaspoon of garlic powder works if you're in a pinch.

2 tablespoons tomato paste

Adds depth and color. No need to buy a whole tube – leftover paste freezes well in ice cube trays.

1 tablespoon soy sauce or tamari

For saltiness and umami. Use tamari for gluten-free. Coconut aminos also work.

1 teaspoon dried thyme

Or 1 tablespoon fresh thyme leaves. Rosemary is a good substitute.

2 cups (480ml) vegetable broth

Low-sodium is best so you control the salt. Water works in a pinch, but broth adds flavor.

2 pounds (900g) potatoes, peeled and quartered

Russet or Yukon Gold make the fluffiest mash. Yukon Golds are buttery without adding much.

1/2 cup (120ml) unsweetened plant milk

Oat or soy milk are creamiest. Any unsweetened kind works.

3 tablespoons vegan butter or olive oil

Vegan butter adds richness. Olive oil is lighter but still good.

Salt and black pepper to taste

Don't skip the pepper – it brings out the other flavors.

Step-by-Step Instructions

1. Cook the lentils

In a medium pot, cover the lentils with 3 cups (720ml) water and bring to a boil. Reduce heat and simmer for 15-20 minutes, until tender but not mushy. Drain and set aside.

2. Boil the potatoes

Place the quartered potatoes in a large pot and cover with cold water. Add a pinch of salt. Bring to a boil and cook for 15-20 minutes, until a fork slides in easily. Drain well.

3. Sauté the vegetables

While the potatoes cook, heat the olive oil in a large skillet over medium heat. Add the onion, carrots, and celery. Cook for 5-7 minutes, until the onion is translucent and the carrots begin to soften.

4. Add mushrooms and garlic

Stir in the mushrooms and garlic. Cook for another 5 minutes, until the mushrooms release their liquid and start to brown. If the pan gets dry, add a splash of broth.

5. Build the filling

Add the tomato paste, soy sauce, thyme, and cooked lentils. Stir to coat. Pour in the vegetable broth and bring to a simmer. Cook uncovered for 10-15 minutes, until the sauce thickens slightly. Season with salt and pepper.

6. Mash the potatoes

Mash the drained potatoes with the plant milk and vegan butter until smooth. Season with salt and pepper. If you like, stir in a handful of chopped fresh parsley.

7. Assemble the pie

Preheat your oven to 400°F (200°C). Spread the lentil filling evenly in a 9×13-inch baking dish. Spoon the mashed potatoes on top and spread gently to cover. Use a fork to create ridges.

8. Bake until golden

Place the dish on a baking sheet to catch any drips. Bake for 25-30 minutes, until the filling bubbles at the edges and the potato peaks are golden brown. Let it rest for 10 minutes before serving.

Tips & Tricks

• Don't skip the tomato paste and soy sauce – they give the filling that deep, savory flavor that makes it taste like the classic.
• If your mashed potatoes are too stiff to spread, add a splash more plant milk. They should be soft but not runny.
• The filling should be saucy but not soupy. If it looks too wet after simmering, let it bubble uncovered for a few extra minutes to thicken.

Delicious Variations

Sweet potato topping

Swap half the potatoes for sweet potatoes for a slightly sweet, colorful top.

Add greens

Stir in a couple handfuls of chopped spinach or kale with the mushrooms – it wilts right in.

Spice it up

Add a teaspoon of smoked paprika or a pinch of cayenne to the filling for a smoky kick.

👨🍳 Chef's Note: If you want a richer gravy, stir in a tablespoon of nutritional yeast with the broth. It adds a cheesy, savory note without any dairy.
