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.

Hello,
What size casserole dish do you recommend?
Kind regards, Diana
The casserole dish in the photos is 9×9. You could make it in a larger dish, but not a smaller one as it’s really full in a 9×9.
