Typically, when I make a slow cooker pot roast I cook an extra large beef roast for leftovers. There are so many wonderful ways to use leftover pot roast. Two of my favorites uses for leftover post roast are Slow Cooker Salsa Verde Beef Enchiladas and this super easy Shepherd’s Pie with Leftover Pot Roast.
With St. Patrick’s Day coming up, I thought now would be the perfect time to update this Shepherd’s Pie recipe with some fresh, new images. While the recipe was first published in August of 2011, the delicious recipe remains exactly the same.

Do I have to use pot roast to make Shepherd’s Pie?
No. Ground beef, ground turkey and lamb are all good substitutes for the pot roast.
What kind of mashed potatoes should I use?
I have a tendency to make double the amount of potatoes that I need. I love using the leftover potatoes in recipes like this one. It makes a great snack too! Use whatever mashed potatoes you fancy. Even frozen or refrigerated mashed potatoes will work. Check out my recipe for freezer mashed potatoes.
Is this a traditional Irish food?
Shepherd’s Pie is a traditional Irish dish that is perfect for celebrating St. Patrick’s Day. Though, traditional Irish Shepherd’s Pie would actually call for ground lamb but this version or shepherd’s pie made with ground beef is what my family prefers.
