Delicious – will definitely make this again!
I haven’t tried it yet, but was hoping to make it vegan for my niece. I can make adjustments in the potatoes, but what do I use instead of Worcestershire sauce? I’ve searched for vegan versions, but they are expensive and/or hard to find. I’d hate to spend $10 on a bottle just to use 2 teaspoons. HELP!
You can omit it. 🙂
Fantastic! I added lentils just because I love lentils. Love this when I need a gravy/mashed potato fix.
HI Gina,
Thank you SO much for this delicious recipe!
If made ahead, how long should it be heated before doing the broiling step? I want the inside to be nice and hot!
Thank you
Id say 30 minutes?
Can you make ahead and freeze it? If so any changes to the recipe?
Longtime follower, first time commenter, eternal appreciator.
Can’t wait to try this! Catie and Alyssa – let’s swap notes!
Making this tonight for dinner!! 🥔
Let us know!!
Very easy to make.
THIS IS SO GOOD! We are newly gluten and dairy free but also trying to add meat free meals to our life and this hit the spot!
Left over SkinnyTaste Garlic Mashed Potato’s? Is that even a thing? Lol. This looks amazing! Trying it soon!
This was absolutely scrumptious! Used baby Bella’s that were on sale. Added a little red wine. Other than that followed recipe. Best veggie Shepard’s pie I’ve ever made. Even the carnivore loved it.
Hello!! I would like to know if I can use an oven for the portobello sheperds pie, instead of the broiler. I dont have one
to use your oven put the oven rack to the highest setting. Put the temp of the oven to 500 degrees or broil-its on the temp knob. and then cook as directed.
This was super tasty! I always make a few changes to suite the tastes of my wife and I, but I have to say this is one of the better veg shepherd’s pie recipes I’ve tried.
Here are the few changes I made:
Added celery for a bit of crunch.
Used Geo Watkins Mushroom Ketchup instead of Worcestershire. It’s good stuff and my go-to substitute.
Used more tomato paste than the recipe called for.
Used baby bella’s & button mushrooms instead of portabellos. They were the freshest mushrooms at the store, and they worked great.
Added a bit of shallot.
Very minor changes, just based on what I had around and what looked fresh at the store. The only real addition I made is adding lentils (broiled in the oven until slightly crunchy) after the veggies were cooked prior to layering potatoes on. Went with a combination of russets & red potatoes… used buttermilk and Kerrygold for the fat after drying and ricing the potatoes.
For sides, I went with a quick pickle of jalapenos, sweet mini peppers, & red onion left over from last night. Also added a bit of mushroom gravy (recipe stolen from Chef John.)
Thanks for the recipe!
This was outstanding! Thank you for another great recipe. Everyone loved it, even my son who is very picky about vegetables.
Excellent recipe!…..My only critiques would be to let the veggies cook longer and make ahead! the flavors combine so much better when they have time to meld together…..Will make again.
This was delicious! You will not miss the meat!
AMAZINGGGGGGG!!!!! COMFORT FOOD WITHOUT THE GUILT! Made with cauliflower mash!
Absolutely incredible! Husband and I made it together – not too complicated and wonderful taste. this one’s a keeper!
Did this tonight really delicious but I did the Cauli mash instead , now was wondering if I could freeze please Gina ? putting a pic of it on my Instagram #kris.annecooking
Great recipe! Have made multiple times
Yummm ……, thank you so very much for this amazing recipe. It’s incredibly delicious as well as satisfying!!
Worcestershire Sauce is NOT Gluten Free – this should not be advertised as a GF recipe.
Lea & Perrins Worcestershire Sauce is cholesterol free, fat free, preservative free, gluten free and has 80% less sodium than soy sauce.
This was really good for a veggie shepherds pie, the mushrooms were a great meaty substitute, and the flavors were splendid. I questioned the use of parmesan at first, but it gives the potatoes a nice crunch!
This was so good for dinner last night and I just had some leftovers for an early lunch. So good and flavorful! I opted for the rosemary.
My family loved this, thank you!
This was very tasty and made for great leftovers! Even my meat loving husband enjoyed it 🙂
This dish turned out amazing!!! I made it last night and my husband and I looked at each other and said “it’s a keeper.” The only thing different I did was add 2 tsps of dried thyme instead of the two tbs freash it calls for and I followed my own recipe for mashed potatoes (potatoes, milk, and butter). Thanks so much for posting!!
Oh my, this is DELICIOUS. Even my meat-loving husband loved it. Make it; you won’t be sorry.
Made this tonight for dinner and would rate this recipe very good! Would definitely make again! Thanks:)
We loved this recipe! My kids aren’t fans of mushrooms so I ended up chopping them up finely and then added some vegetarian crumbles – no one had any idea it was meatless and my 7 y/o son said it good enough to bring for leftovers at school.
I made 2 of these and froze 1 – what would be the cook time amd temp for the frozen 1?
Do you think the sautéing step could be done in the Instant Pot to cut down on time? So, rather than sautéing for the various steps, maybe cooking on high pressure for 5 minutes or something like that?
I’ve been looking for a good vegetarian shepherds for so long, and I’ve finally found one. This is a great (and filling) recipe! Thanks Gina!
This has the “V” logo which I’m assuming means it’s vegetarian? Parmesan cheese typically isn’t vegetarian friendly and Worcestershire sauce contains anchovies. I substituted mozzarella and used soy sauce in place of the Worcestershire.
I think you are confusing vegetarian with vegan. Vegetarians eat animal products that can be harvested from animals without killing them such as eggs and milk.
Most parmesan has rennet in it, which is comes from the stomach of baby animals. 🙁 Whole Foods brand of parmesan cheese has no rennet, so that’s what I use..
Approx. how long will it take to get the changes for the new Freestyle program. Are you going to
publish a list like you did last time.? What do you think of the new program. Goiing to class today to find out about.
I am updated from 2017 until 2010. Should all be done before the year ends.
This is comfort food in a bowl without the guilt. So so good! 100% part of my regular rotation of recipes moving forward!
Gina – Can this be frozen? – Angie
Also, would this work with your Garlic Sweet Potato Recipe?
https://www.skinnytaste.com/garlic-sweet-potato-mash/
sure!
Sure!
Omg this was so amazing! Even my dad loved it! I’m happily eating leftovers at my desk for work and everyone is saying “wow what is that that smells so good”. Definitely adding this to regular rotation
Great!
Made this last night and it was delish!! The only change I made was substituting sweet potato mashed. Will definitely be making again 🙂
wonderful!
My husband and I cannot have corn, nuts or seeds for medical reasons and these have been cut out of our diet by our Doctor. What can we use in place of the corn? Your help would be greatly appreciated….Thank you in advance.
Swap them for more of the other veggies.
Hi there – I haven’t made this yet, but don’t eat peas or corn myself. I’m planning to add diced zucchini and make a root veggie mash of parsnips and rutabaga for the topping. The vegetable mixture sounds very forgiving so I may try adding some shredded brussels sprouts in there too.
Is Worcestershire sauce vegetarian? I don’t think it is.
Annie’s sells a vegan one. http://amzn.to/2zM5OYL
Thanks Gina! I love your recipes and comments. Since Annie’s isn’t kosher anymore, would Worcestershire powder work? Amazon sells
I have not tried but sure!
I’m trying to be lower carb (max 40 per meal) so I think maybe doing half cauliflower mash & half mashed potato may be a good idea. Need to figure out the carb count to see if it would reduce it enough.
I made this tonight and it was so good! I added a cup of red lentils and some celery and put some mashed sweet potato on one end too. Delicious! I would highly recommend the recipe! Thanks!
Excellent idea on the lentils, I was thinking of a protein to add to the dish.
This looks delicious!
Shepherds Pie is made with LAMB. Cottage pie is usually beef, but can be other such as this recipe which sounds very good.
Do you have a point?
Hi, i am wondering if you will be adjusting the Smart Points in your recipes for Weight Watchers?
Thank you,
You do an excellent job, as WW leader I recommend your site to everyone.
Stephanie
Thank you, once I know what the changes are I will.
Hi I’m wondering what are points plus? I’m on WW and in the nutrition section I see SP then right next to it points (plus sign)… I’m confused!
Older program. Not something you need to worry about.
This sounds delicious but if following a low-carb plan, do you think mashed cauliflower could be used instead of mashed potatoes? Thanks!
Sure!
I had the same bought!!!
Me and my boyfriend were planning meals for the week and I was like “I really feel like a Shepherd’s Pie!” But the recipe I have didn’t see very healthy. I abandoned the idea and came over the Skinnytaste and saw this was front and center and was so excited! This is REALLY GOOD! My mashed potatoes come out weird (still not sure what happened there) but they were fine once I spread them and broiled. The portobello mushrooms are nice and meaty, and the whole dish is so comforting. Can’t wait to make it many more times this winter! Thank you!
perfect!
