Love shepherd's pie? Me too! Especially this Mushroom Shepherd's Pie. It's full of mushrooms and your choice of ground meat (or vegetarian sub!) and topped with the most delicious brown butter potatoes. It's a healthy dinner recipe that is sure to please.
Do you see those mashed potatoes up there looking like some flaky pastry crust? Impersonator! In the best possible way, of course.
That potato crust beauty starts out its life as humble mashed potatoes. It comes into its own when it's happily full of brown butter – or browned ghee if you're on The Whole30, plenty of sea salt, and just the right amount of thyme. Even before they're baked, they're mashed potatoes to dream about.
But I'm jumping ahead. First I need to tell you all about that mushroom shepherd's pie that's holding up the crust.
Remember back in the spring when I made that Curried Vegan Shepherd's Pie with Sweet Potato Topping? That was a delicious recipe, but when I made it my handsome man said, “Can you please make a REAL shepherd's pie?” Real, as in not vegan.
Shortly after the real shepherd's pie request, I did my first Whole30 Program. While I've loved eating a paleo diet about 75% of the time, I had never committed to it so fully. I was amazed at how good I could feel by eliminating all grains, beans, legumes, dairy, and sugar from my diet.
Now, I'm still an eat everythingarian but I have definitely started to lean towards a meat-heavier diet. (You might have noticed the meatier recipes on the blog lately.) I just feel so much better eating that way!
But … I have all sorts of love for my vegetarian and vegan friends out there and don't want to leave you out of all the recipes here on the blog. So, while I used ground beef in this mushroom shepherd pie, you could definitely use a vegetarian sub if you wanted. In my vegetarian days, I used to eat veggie ground round. It would totally work in this recipe.
So now that we've got the long winded “this mushroom shepherd's pie recipe is good for everyone” talk out of the way, let me tell you about the recipe itself.
Your Mushroom Shepherd's Pie Game Plan
→ Saute those onions. You want them to start caramelizing so they're deliciously sweet and fragrant. Side note – is there anything better than the smell of cooking onions? I swear it's half the reason why I like to be in the kitchen so much.
→ Brown those mushrooms. Those beauties add so much flavor to the dish. They have that umami thing going on, so even if you're making this vegetarian, you still get big time flavor.
→ Garlic, of course. No good recipe should be without a hearty amount of garlic, IMO. You with me?
→ Tomato paste magic. By cooking the tomato paste for a few minutes, the natural sugars in it start to caramelize. This adds a ton of extra flavor to the dish. Use this trick whenever you use tomato paste. I'm looking at you, Bolognese sauce!
→ Worcestershire sauce. That stuff is a powerhouse of flavor. It's deep and salty and has tons of that umami stuff going on from the anchovies. Note: there are vegetarian versions and I've got a few subs for Whole30-ers!
