Vegetable-packed meals are my specialty, and this recipe for hearty, homemade vegetarian shepherd’s pie fits the bill. Tender veggies are topped with fluffy mashed potatoes. Unlike many meatless shepherd’s pies, this recipe doesn’t rely on lentils. Assembly is easy, too—vegetarian comfort food at its finest.

When you’re craving a hearty, comforting dinner, there’s one food that never disappoints…mashed potatoes. Buttery, herby mouthfuls of yum, they’re even better when paired with other hearty ingredients!
Case in point: Shepherd’s Pie.
Traditionally made with ground beef or lamb, we’re skipping the meat in favor of an all-veggie version complete with peas, corn, carrots, celery, and onion. It’s the ultimate vegetarian comfort food.

Key ingredients
Jump to the recipe card for exact measurements – this is just an overview!
- Yukon Gold Potatoes: These are key to that buttery, smooth mash. Their natural creaminess means you don’t need much butter or yogurt to get the right texture.
- Greek Yogurt & Butter: Tested multiple versions—Greek yogurt adds light tang and protein without heaviness. For vegan, dairy-free yogurt and margarine work perfectly.
- Mushrooms: The umami powerhouse! When browned properly, they mimic the savory flavor of traditional meat filling.
- Carrots, Celery, and Onion: This trio forms the aromatic backbone. Sautéing them slowly brings out their natural sweetness.
- Tomato Paste + Herbs: Adds rich depth, and that splash of fennel seed is the secret weapon that keeps the gravy tasting hearty and complex.
- Flour & Veggie Broth: Simple, but tested for the perfect thickness. Rich enough to hold its shape, not gluey.
- Corn + Peas: These are added last to keep them bright and juicy.

Make it ahead of time
You can assemble this vegetarian casserole up to two days in advance. When ready to enjoy it, just pop it in the oven!

Sarah’s Switch Ups
- Want more umami? Add a teaspoon of soy sauce or miso paste to the gravy.
- Crispy topping hack: Use a fork to create ridges in the mashed potatoes before baking. Those ridges brown beautifully if you turn on the broiler for a minute at the end of cooking.
- More Veggies: Want to add extra veggies? Green beans and finely chopped broccoli both work well!
- Extra Protein: Add cooked lentils or crumbled tempeh to the veggie mix (reader’s have tried this and also said it was delicious–see comments!)

Mixed Veggie Vegetarian Shepherd’s Pie (No Lentils!)
Ingredients
Mashed Potatoes
- 2 lb Yukon Gold potatoes, about 6, 0.9 Kg
- ½ cup full fat plain Greek yogurt, can sub dairy-free, 120 g
- ¼ cup unsalted butter, can sub dairy-free, 56 g
- ¼ tsp salt
Filling
- 2 Tbsp olive oil, 30 mL
- 16 oz sliced mushrooms, 450 g
- 1 medium yellow onion, thinly sliced
- 3 cloves garlic, minced
- 4 medium carrots, about 1½ cups roughly chopped
- 4 medium ribs celery, about 1½ cups sliced
- 2 Tbsp fresh herbs, chopped rosemary, thyme, and/or bay leaf
- 2 Tbsp tomato paste, 20 g
- 1 tsp fennel seed
- 1 tsp smoked paprika
- 3 Tbsp all-purpose flour
- 2 cups vegetable broth, 470 mL
- 1 14-oz can corn, drained, 425 g can
- 1 cup frozen peas, 100 g
Instructions
- Mashed Potatoes: Preheat oven to 375°F (190°C). Bring a large pot of water to a boil. Peel and roughly chop 2 lb Yukon Gold potatoes, then add to boiling water. Cover and cook until fork tender, about 15 minutes. When finished, add to a large bowl and mash, then mix in ½ cup full fat plain Greek yogurt, ¼ cup unsalted butter, and ¼ tsp salt. Set aside.
- Saute Veggies: In a large oven-safe pot, heat 2 Tbsp olive oil over medium-high heat. Add 16 oz sliced mushrooms and cook until they lose their moisture and begin to turn golden brown, about 5 minutes. Add 1 medium yellow onion (sliced), 3 cloves garlic (minced), 4 medium carrots (diced), and 4 medium ribs celery (diced), continuing to cook until vegetables are slightly soft, about 7 to 10 minutes.
- Gravy: Stir in 2 Tbsp fresh herbs, 2 Tbsp tomato paste, 1 tsp fennel seed, and 1 tsp smoked paprika. Sprinkle in 3 Tbsp all-purpose flour and stir to evenly coat everything. Slowly drizzle in 2 cups vegetable broth, stirring as you add it. Heat the mixture until it thickens slightly. Stir in 1 14-oz can corn and 1 cup frozen peas.
- Assemble: Spoon the mashed potatoes over the filling in the pot, spreading it into an even layer (you can crimp the top with a fork to get little crispy edge pieces).
- Bake, uncovered, for 20 minutes. If desired, cook under the broiler for a few minutes to help brown the surface of the mashed potatoes.

I love the sound of this dish, I’m looking forward to making it, I think the one thing I would change is the mushrooms. I have a childhood hate-on with mushrooms! I think I would sub TVP and GWashingtons Beef Broth (its vegan) soak instead. I usually bring my broth to a boil and then add the TVP, then cook it down until the broth has been almost completely absorbed. Then add the rest of the ingredients to the TVP and continue on with your recipe!
That sounds like a great plan. I would love to hear how it goes. Enjoy!
My family loved this!
I added some sauted tempeh too.
The pie is super delicious.
Big smiles over here Sashi, so glad your family enjoyed the recipe!
I made this shepherds pie for a gathering I had and everyone loved it! I substituted zucchini for corn and it was so good! Thank you for sharing your recipes.
Love hearing that everyone enjoyed the recipe Tracy, thanks for trying it!
This is comfort food at it’s best! This is also soooo flavorful! I highly recommend this delicious recipe and recommend following the advice to add the miso!
Thanks so much Terri, so happy to hear you enjoyed the recipe!
I was thinking of adding a can of lentils to the mix for more protein and fibre. Has anyone tried this? Any thoughts on how this would affect the recipe?
I think it would work!
I used sweet potato rather than Yukon. Delicious! Will make this again.
That sounds delicious. Thanks so much for letting us know how it went, Wendy! Happy eating!
Very tasty, easy to follow and fix.
So thrilled to hear it, Glenda! Happy eating!
This wasdelicious! Made mash earlier in the day and filling later. It would have been harder for me to do both components simultaneously. Amazing recipe!
Love hearing this, thanks so much Lori!
For the Shepard pie, can I add sweet potatoes with the white potatoes
It’ll change the flavor profile a bit, but I bet it would still be delicious! I would love to hear how it goes if you try it out.
