As the days get shorter and colder, I find myself turning to AIP comfort food recipes like this Greek shepherd’s pie. This is also the short season when my local Trader Joe’s stocks the purple skinned, white fleshed murasaki sweet potatoes, which make a perfect shepherd’s pie topping when you can’t eat nightshades.
All about white sweet potatoes
Did you know that there are dozens of varieties of sweet potatoes, with many different colored skins and hues of flesh ranging from practically pure white to vibrant purple? It’s a shame that the realities of our modern produce production and distribution system means that people mostly only have access to one variety of sweet potato – which if you ask me, is not even close to being the tastiest.
For this recipe, you can use any type of sweet potato you can get your hands on, even that means only the usual orange fleshed variety. But some white sweet potatoes have a starchier texture and slightly less sweet taste, and of course they have the visual appeal of a traditional potato topping. If you don’t see anything in our grocery store labeled as a “white” sweet potato, try looking for and asking for them by one of the variety names below. Click the name to get more information and see a picture.
- Murasaki (also known as Japanese or “oriental”) – these have a purple skin and a white flesh and taste most like a russet potato. My favorite for this recipe.
- Hannah – these have a tan skin and an off white, yellowish flesh. Also good for this recipe.
- Jersey – these have a tan skin and a creamy white flesh. Also good for this recipe.
- O’Henry – these have a tan skin and white flesh but taste much like an orange sweet potato. My least favorite choice for this recipe.
About the flavors in this recipe
I’ll be honest, even the least sweet of the sweet potatoes still is going to taste sweet. But rather than fight it, for this shepherd’s pie iteration, I decided to embrace it and added lemon juice and lemon zest directly to the mashed potato topping along with herbs in order to create something reminiscent of Greek potatoes.
Options for the filling
Traditional shepherd’s pie is going to feature lamb as the meat, but you can use ground beef if you prefer. I wanted some extra richness and to de-emphasize the lamb flavor in this version, so I used a combination of lamb and pork but I’m certain it would be tasty made with all lamb.
You can use any combination of shredded vegetables, totally about 3 cups in volume, that you’d like. I’ve made variations with shredded parsnips, carrots, cabbage, and more. But since I was already at Trader Joe’s to pick up the bag of murasaki sweet potatoes, I decided to make life easy on myself and also grabbed a 12 ounce bag of their organic broccoli slaw, which is merely shredded broccoli stalks and carrots. If you don’t have a Trader Joe’s store near you or want to make your own, just shred 3 or 4 carrots and the stalks from 2 or 3 heads of broccoli (saving the florets to eat in another dish).
Tips for freezing
This dish freezes very well. Make it as described in the recipe below but do not bake. Cover with an airtight seal and transfer to refrigerator. I like this casserole dish set, because it includes plastic lids that I can snap on and then place directly in the freezer without worry but also includes oven safe glass lids which are useful for some recipes..
To reheat, allow the dish to completely thaw first and then heat in a 425°F oven for 25 minutes. Or, if taking directly from the freezer, remove the plastic lid and put the glass lid on and place in a cold oven (this will prevent the dish from cracking because it can slowly heat as the oven temperature goes up). Turn oven temperature to 425°F and set a timer for 45 minutes. Use a knife or fork to check the middle and make sure it is hot all the way through.
