Recipe FAQs
What mushrooms should I use in this shepherd’s pie?
You can use a variety of mushrooms! We love grabbing some cremini and portobello mushrooms, and you can also throw in some button, shiitake, or oyster mushrooms!
Can I make mushroom shepherd’s pie ahead of time?
Absolutely, you can! The only thing is that you’ll need to bake it a little longer as you’ll be cooking it from cold. Make sure to either let your casserole dish warm up on your counter before putting it into the hot oven or add it to the cold oven and let it warm up as the oven preheats. 🙂
How do I store leftover mushroom shepherd’s pie?
Allow it to cool to room temperature before transferring it to an airtight container and popping it in the fridge. You can keep it in there for 3-4 days or freeze it for up to three months. Leftovers freeze well; just thaw them in the fridge a day before you intend to enjoy them. For the best results, reheat leftovers in the oven.
What potatoes should I use?
We opt for russet potatoes. Yukon gold works well, too.

In keeping with my TEM streak/New Years resolution to make it all(!!), just made this recipe! It took me freaking forever (like 1.5 hours), but I chalk that up to my kitchen inefficiency (user error) AND my inefficient kitchen (NYC). For one, another home run for this site! Really delicious recipe, and the potatoes are incredible. All mashed potatoes should be prepared this way. I used veggie meat, and if I make this again, next time I’ll brown that separately, maybe in butter, to get it really rich and flavorful before adding to the onion/mushroom pot. That was quite a lot to put in one pot, so I’ll plan better for that next time to ensure it all cooks evenly. My potatoes dried out for some reason, so I ended up giving them a quick reheat with a bit of evaporated milk, hot water, and a little extra butter before topping the pie with them. I don’t know what I did wrong there, but it still worked out in the end. I also don’t love the Worcestershire sauce I bought as it made the dish too sweet, or that could have been the faux meat. Not sure. Would definitely make again and try to get it perfect. The first time you make anything, you’re really just getting to know each other. It’s almost like a rehearsal for the real thing. 🙂 Thank you for this!
I love that you’ve been enjoying the recipes here! Hooray!!
Served 7 for supper and 2 went back for seconds. Used a local organic spicy sausage. This is another solid keeper from this, my favourite site.
I’m so happy to hear it was a hit!
I was on a low carb kick, so I made these with pan-fried mashed cauliflower instead of potato. Also threw in dried tomatoes and a cup of beef stock with corn starch. Followed everything else. VERY savory. Only wish I used more stock so there was noticeable gravy.
Good call on using mashed cauliflower!
Is it okay to make ahead and put in the fridge until you are ready to bake?
Absolutely it is! The only thing is that you’ll need to bake it a little longer as you’ll be cooking it from cold. 🙂
That is so great to hear! Hooray!!
Prepared the veggie version – came out AMAZING!
Thanks so much for lovely recipes 🙂
I’m so happy to hear you liked the recipe! Hooray!!
My 5 year old said this was his new favorite meal ?
Your 5 year old has good taste! It makes me so happy to hear he has a new fav!
If you are making this recipe Whole 30 compliant, don’t bother the step of browning the ghee. Since the milkfats have already been removed, the ghee will never brown. Heat the ghee, sautee the garlic and thyme lightly and add to the mashed potatoes.
Delicious! My husband asked me to put this recipe on a regular rotation for our dinners. Thank you Kristen! I love your recipes. All of our favorite meals are your ideas.
That makes me so happy to hear! Horray!!
Hello, what size ovenproof baking dish should you use?
The one in the pictures is 9×9 but has quite high sides. A 9×11 pan would work well, too. 🙂
It is! It’s quite a bit bolder than the last, isn’t it? And yes to the brown butter! You should totally try it. 🙂
Hi! This looks amazing! Was just wondering what type of potatoes did you use?
Thanks Helen! I used Russet potatoes. 🙂
It was a hit! Thanks for sharing. Loved this – adding it to my repertoire!
I’m so happy to hear you liked it!!
I love this dish. I especially love the potato part of the recipe, as I think you can easily adapt it to other recipes. I used ground chicken, and I second guessed myself on the amount of tomato paste the recipe called for, but it was really lovely when contrasted with the buttery potatoes. Thank you for this recipe! I have already Pinned it! 🙂
I’m so happy to hear you liked the recipe! I agree, the potatoes are my favorite part!
Hi! What’s the serving size for this? Trying to figure out if I️ can feed 4 or need to double the recipe!
It’s perfect for 4 people!
Thanks, Marcie! It really did turn out delicious. 🙂
