It’s not St. Patrick’s Day without shepherd’s pie. This low-carb slow cooker version of the Irish classic is not just healthy (paleo, whole30) but easy too.
St. Patrick’s Day is right around the corner. This is my favorite St. Patrick’s Day recipe. I prefer it to corned beef & cabbage and beef stew.
There are a lot of different versions of ‘traditional’ shepherd’s pie. To me, this is one of those recipes that you should tweak to your liking or dietary need. I recommend using ground lamb if you can get your hands on some. If not, ground beef will do just fine. Don’t like thyme? Use rosemary. Don’t eat red meat? Use ground turkey. Technically if you use meat outside of mutton or lamb then it’s cottage pie not shepherd’s pie. But it still tastes good so who cares. Since peas are not whole30 or paleo, I used diced zucchini!
While this is a relatively easy dish to make in the slow cooker, it is a 2-part recipe. The mashed cauliflower is added during the last 30 minutes of cook time.

Mashed cauliflower replaces potatoes for a low-carb alternative.
You can also swap out mashed cauliflower for mashed sweet potatoes or a mixture of the two. My husband doesn’t care for mashed cauliflower because they’re a tad ‘too runny’ for him. A great way to thicken up ‘runny’ cauliflower is to mix in a sweet potato or potato depending on your dietary needs.
Since there’s no cheese and it’s not cooked in the oven, don’t be surprised if your mashed topping doesn’t crisp on top like you’re used to with a regular shepherd’s pie.

I made it and it was great! Where are the nutrition facts for the recipe?
I’m so glad to hear you enjoyed the recipe!
I don’t have a food processor? What do you recommend I use instead?
Any basic blender should work!
OMG….this was AMAZING! I did the full head of cauliflower and whole large sweet potato since I like a thicker mash, and it was so good. This is going to become a regular rotation! Next time totally making a double batch to freeze. 🙂
If I were to add sweet potatoes, how much should I add and would I cut back on the cauliflower?
About 1/2 lb sweet potatoes. Since the cauliflower is a little wet/runny you don’t need to cut back on the cauliflower, just add in the potatoes. Enjoy!
Ok, so I saw this when it posted and just came back to it after finding ground lamb at the store. So I have all the ingredients except for Thyme or Rosemary, is there any other spice I could substitute or are those really the best for a more authentic taste? Thanks!
I apologize for the delay, I’m traveling at the moment. You can pretty much substitute any herb whether it be basil, oregano, rosemary or thyme. While it might not have the exact same taste, it should still turn out good:-)
Can’t wait to try these
Wow. Looks yum. I love slow cooking recipes. I don’t eat meat. But would love to share it with friends who do!
Could you swap in sauteed Portabella mushrooms for the meat? I am trying to make a vegetarian keto dish for a potluck.
Absolutely. That sounds fantastic. Enjoy!
How it looks super yummy! Need to make at home.
Happy Thursday! Kisses,

I had no idea that Shepherds pies were a traditional Irish dish but I like the sound of your version. I am intrigued to try the mashed cauliflower as well!
I’m a fan of shepherd’s pie AND of slow-cookers, so I’ll give this a try. Your photos are fantastic! I just want to reach through the screen and take a bite! Shouldn’t have looked at this at lunchtime on a snow day…

There’s really nothing quite like Shepherd’s pie. It’s a staple in my house not just because I’m broke but because it’s so good and it can go such a long way! Perfect cozy winter food!
Oh I love shepherds pie it is really good with the sweet potatoes on top. I would’ve never thought to switch out the potatoes for cauliflower I’m not exactly sure my husband would go for the cauliflower either.
Love how you made this traditional St. Paddys recipe in a Paleo form. The changes that you made would be barely noticed and you get the healthy benefits!
Surprisingly I’ve never had Shepard’s Pie before, my husband was telling me I’d like it so I think I’ll give this recipe a try!
Oh wow this looks awesome!! My hubs doesn’t really like melted cheese, so I love how this doesn’t have it!!
