This classic comfort food is so easy in a slow cooker! Slow Cooker Shepherd’s Pie came from some creative women trying to use their leftovers back in the 1800s. I guess not much has changed since the 1800s, women just trying to turn their leftovers into something new for dinner.

This meaty meal is filled with vegetables and topped with mashed potatoes. I love mashed potatoes so this is an easy way to get my fix! The flavors come together into the perfect, cozy meal. Feel free to swap the lamb for all beef depending on what you like.

What is the difference between Shepherd’s Pie and Cottage Pie?

The difference between Shephard’s Pie and Cottage Pie is the meat you use. Traditionally Shepherd’s Pie is made with lamb and Cottage Pie is made with ground beef. However, as time has gone on most people call both versions Shephard’s Pie. There is a very serious debate over what is Shepherd’s Pie and what is Cottage Pie for some people but I made mine with ground beef but still call it Shepherd’s Pie. Here in the United States, we make Shepherd’s Pie with ground beef typically. However, in the United Kingdom, they use lamb in their Shepherd’s Pie. They call a similar dish using ground beef, Cottage Pie.

Tips for Making Slow Cooker Shepherd’s Pie

Mashed Potatoes– You can use leftover mashed potatoes, instant mashed potatoes, or make them fresh. They are all delicious and work great!

Ground Beef or Ground Lamb– I have made this both with a mix of ground beef and ground lamb and with only ground beef. It’s easier for me to find ground beef so that’s what I use. You can use either beef or lamb or even both!

Need A New Crock Pot?

My favorite is this Crock Pot 7 quart Programmable Slow Cooker. First and foremost, I love being able to set the timer in case I’m not home when the food is finished cooking and it just switches to warm. Plus you can lock the lid and just carry it to a party. Not only is it easy to carry but also you will never lose another Tupperware or serving dish again at a potluck party!
