After making (and devouring) my Slow Cooker Mashed Potatoes last week, I was really craving some shepherd’s pie. But, because of the strict budget I’m working with, I decided to make a vegetarian shepherd’s Pie. This warm and comforting dish is still full of deep and rich flavor, even without the meat, and I love all the color and texture that the vegetable medley brings to the plate.
What’s In Vegetarian Shepherd’s Pie?
To make up for the meat I made sure to use plenty of vegetables, including mushrooms, which give a nice “meaty” umami flavor. I also added in a cup of cooked lentils for bulk and extra protein. Lentils are great because they cook super fast, have a small shape, and a mild flavor that helps them blend really well into recipes. I often use them half and half with meat to stretch my dollar, but that same technique also works well with vegetables. If you’re not a fan of lentils, no worries. You can just leave them out and you’ll still have a delicious and hearty straight vegetable filling for your vegetarian shepherd’s pie.
What Kind of Mashed Potatoes Should I Use?
I made a second slightly smaller batch of my Slow Cooker Mashed Potatoes to top the pie, but you can use any type of leftover mashed potatoes you have (make sure to use vegetable broth in your mashed potatoes to keep this recipe vegetarian). Another great option is to use my Olive Oil Mashed Potatoes, which are dairy-free, and will make this whole Shepherd’s Pie vegan!
You can make your mashed potatoes fresh, or use leftovers. Just be sure to warm them up before trying to spread them onto the pie because cold mashed potatoes don’t exactly “spread.” LOL
Vegetarian Shepherd’s Pie
Servings 6Ingredients
- 1 cup cooked lentils (optional)* ($0.21)
- 2 cloves garlic ($0.16)
- 1 yellow onion ($0.31)
- 1 Tbsp olive oil ($0.16)
- 3 carrots ($0.37)
- 2 ribs celery ($0.38)
- 8 oz. button mushrooms ($1.99)
- 3/4 tsp salt ($0.03)
- 1 tsp dried thyme ($0.10)
- 1/2 tsp smoked paprika ($0.05)
- Freshly cracked pepper ($0.05)
- 1 Tbsp tomato paste ($0.11)
- 1 Tbsp flour ($0.01)
- 1 cup vegetable broth ($0.13)
- 1 cup frozen peas ($0.45)
- 4 cups mashed potatoes ($1.36)
Instructions
- Mince the garlic and dice the onion. Sauté the onion and garlic with olive oil in a large skillet over medium heat until the onions are soft and transparent (3-5 minutes).
- While the onions and garlic are cooking, peel and dice the carrots, dice the celery, and slice the mushrooms. Once the onions are soft, add the carrots and celery to the skillet and continue to sauté until the celery begins to soften slightly (5 minutes).
- Finally, add the mushrooms, salt, thyme, smoked paprika, and freshly cracked pepper to the skillet. Continue to sauté until the mushrooms have fully softened (3-5 minutes). Add the tomato paste and flour to the skillet. Stir and cook the vegetables with the flour and tomato paste until the vegetables are coated and the pasty mixture begins to coat the bottom of the skillet (about 2 minutes).
- Add the vegetable broth to the skillet, stirring to dissolve the flour and tomato paste from the bottom of the skillet. Allow the broth to come up to a simmer, at which point it will become slightly thicker. Stir in the cooked lentils and frozen peas, and allow to mixture to heat through.
- Preheat the oven to 400ºF. Pour the vegetable mixture into a casserole dish, or use your skillet if it is oven safe. Spread the mashed potatoes out over the surface of the vegetables and gravy. Use your spoon to make a decorative pattern in the mashed potatoes, if desired.
- Bake the shepherd’s pie in the fully preheated oven for 15 minutes, or until everything is heated through. To achieve a browned surface on the mashed potatoes (optional), turn on the oven’s broiler (and place the pie under it, if not already), and watch closely until the top has browned to your liking.

How to Make Vegetarian Shepherd’s Pie – Step by Step Photos
Using lentils in your Vegetarian Shepherd’s Pie is entirely optional, but I find that it provides more bulk, texture, and protein. You’ll want one cup of cooked lentils for this recipe, which is about 1/3 dry. Cooking lentils is simple, just boil a pot of water, add the lentils, then continue boiling until they’re tender (brown lentils take about 20 minutes). After cooking, drain in a colander. Note: without the lentils you’ll get about four servings out of this recipe.
For the vegetable mix I used 2 stalks celery, 3 carrots, 8oz. button mushrooms, 1 cup frozen peas, 1 yellow onion, and two cloves garlic. Both my celery and peas were on their last leg, but this is a great recipe to use up older vegetables in because they get cooked down and slathered with tasty gravy. :)
Begin by mincing the garlic and dicing the onion. Sauté the onion and garlic with 1 Tbsp olive oil in a large skillet over medium heat until the onions are soft.
While the onions and garlic are cooking, peel and dice the carrots, and dice the celery. Add them to the skillet and continue to sauté for a few more minutes, or until the celery begins to soften just a tad.
While the celery and carrots are cooking, slice the mushrooms. Add the mushrooms to the skillet along with 3/4 tsp salt, 1/2 tsp smoked paprika, 1 tsp thyme, and some freshly cracked pepper. Sauté the mushrooms and seasonings until the mushrooms are soft. My mushrooms came pre-sliced and they were in HUGE pieces, so I broke them up into smaller pieces with my spatula as they cooked.
When the mushrooms are soft, add 1 Tbsp flour and 1 Tbsp tomato paste. Stir the flour and tomato paste into the vegetables until everything is coated in a paste-like mixture. Continue to stir and cook until the paste begins to coat the bottom of the skillet.
When the flour and tomato paste coat the bottom of the skillet (be careful to not let it burn), add 1 cup vegetable broth. Stir the broth and vegetables to dissolve the paste off the bottom of the skillet. Allow the mixture to heat through and come to a simmer, at which point the broth will thicken slightly.
Finally, add the frozen peas and cooked lentils (if using), and allow the mixture to heat through. Preheat the oven to 400 degrees. Pour the vegetable mixture into a casserole dish, or just use your skillet if it is oven safe (this is a deep skillet).
Cover the vegetable and gravy mixture with about 4 cups of mashed potatoes. Spread the mashed potatoes to evenly cover the surface (mashed potatoes spread easier if they are warm). Use the side and back of a spoon to create a decorative pattern in the mashed potatoes, if desired.
Bake the vegetarian shepherd’s pie for about 15 minutes in the preheated oven, or until it’s heated through. To get the nice browned top, turn on the boiler and watch the pie closely until it’s browned on top (if your broiler is under your oven, you’ll have to transfer the pie to the bottom drawer).
Ohhhhh that gravy, though! 😍
Great recipe! My children
, a 5 year old and a 1 year old, loved it! Didn’t have enough potatoes so i added sweet potatoes for the mash. I got an orange sheperd’s pie but nevertheless a delicious one! Thanks!
Delicious! My family loved it, including my meat-loving husband who was skeptical of Shepherd’s Pie without meat. I followed the recipe exactly and used your recipe for crock pot mashed potatoes. I will definitely make this again. Thanks for sharing!
Beth, you said “the filling for the vegetarian shepherd’s pie is slightly more time consuming”, but do you have a recipe for a non-vegetarian shepherd’s pie?
I used to, but I need to remake it, so it’s not on the site right now. :P
Gotcha. I hope you add it at some point, it would be great in the colder months!
Agreed! I thought I was going crazy when I couldn’t find the non vegetarian Shepherd’s Pie recipe! My husband and I LOVE it! Can’t wait for it’s return!
I’m excited to try this! I love your recipes. I’m curious how you made your mashed potatoes. Did you add butter or milk to them, or just mash up some warm potatoes?
I used my Slow Cooker Mashed Potatoes to top the pie. :)
This recipe was amazing, there were a lot of steps, but the reward at the end had a big pay off! The lentils disappeared into the gravy. I didn’t miss the meat at all. This is a really fun recipe. Thank you,.
This is FANTASTIC. The seasoning is so on point that I could feed this to the most hardcore carnivore and they’d love it too. So filling, comforting, and tasty. I usually tweak recipes, but I didn’t with this. I did use my own whipped mashed potato recipe though. I’m so happy to add this to my dinner rotation. Excellent job!
5 stars! At first bite, I wasn’t wow-ed. But just wait. Let it sit in the fridge, reheat it the next day (in the oven), and BAM! The best. This recipe is GOOD. So, so good. I legit ate it for breakfast two days in a row (and lunch…..and dinner…)
I used the vegan mashed potatoes recipe from “My California Roots” blog that uses cashew cream instead of dairy. I recommend sprinkling on some finishing salt and cracked pepper on top before serving. This recipe is definitely more labor intensive than other Budget Bytes recipes, but totally worth it. OH! And little pro tip here, take an HCL and some digestive enzymes before you dine on this dish, it’s rather rich.
I would love to see you do a vegetarian menu challenge. For a week, maybe? It would be so nice to see how you would balance nutrition and budget on a vegetarian diet.
We’re in the beginning stages of putting together some meal plans. :) So hopefully soon!
I made this dish tonight. It was amazing!! Instead of regular potatoes I used sweet potatoes and it was delicious. The flavors and seasoning with the veggies all blends well together. Thanks for the recipe!!
I made this today with a tweak as not a fan of lentils, or celery – added diced swede instead and more mushrooms
It was incredibly delicious!
I don’t really cook very often so I was amazed at how simple it was to follow the recipe.
Thank you :)
Mmmm its so good! Thnks!
Just made this tonight for the next 2 nights for dinner. Cannot wait to try this! I’m a vegetarian, but my husband isn’t do it’s hard to find veg meals that he also enjoys. Thanks!!
This was SO GOOD! I recently decided to become a vegetarian and wasn’t sure if I would miss the lamb, but not at all! The combination of flavors is wonderful! Highly recommend!
Great recipe. I tweaked it slightly but nothing major. I did not use lentils but rather increased the amount of mushrooms slightly (I had more that needed to be used) and added some frozen green beans. I used regular paprika and 1/2 tsp thyme and 1/2 tsp herbes de Provence plus a splash of Worcester sauce (I’m not a huge thyme fan). I also used less mashed potatoes (about 2-1/2 cups of potato/ cauliflower mash with garlic) and found that it was plenty. Delicious!
How could anyone not like this it’s fabulous. I’m a qualified classic chef and have trained and studied under the great Jean Connill and Robert Carrier. It’s a good dish
