👩🍳 FAQs
Here are the questions I am most frequently asked about this recipe.
No - you can use almost any type of cooked meat. Ground beef, roast, pork roast, venison, boneless chicken, turkey... whatever you have on hand.
Not usually because you want that top to develop a thin, golden crust of gooey cheese. If the top starts to brown too much or too quickly you can tent a piece of foil over it.
The first layer is the meat, followed by the green beans and/or carrots. Add any cooked vegetable you like. Next, you'll pour the gravy over the whole thing, and add a layer of creamy mashed potatoes. I like to add a layer of cheese to the top even though it's not traditional.
If you have leftover, homemade mashed potatoes use them. In a pinch you can grab a container of pre-made mashed potatoes from the store - we love the loaded mashed potatoes on top of this!! Just make sure they are thick and not runny.
Well, technically shepherd's pie is made with lamb, and cottage pie (exactly the same except the meat) is made with a beef mixture. In the United States we just call all of it shepherd's pie.

✍🏻 A note from Marye...
I know y'all don't always like the stories bloggers tell so when I have one I try to put it at the very bottom so you can read or skip as you like.
For years I've been using my 8 quart
It's been much harder to learn to cook smaller portions again than it was to learn to cook huge amounts.
I am at that in-between stage where I frustrate myself by having to throw out way too much food.
For the first time in decades I'm having to deal with leftovers. This shepherd's pie recipe is my favorite way to use leftover pot roast! Always a huge hit with the family!
In fact, now I have to plan for extra roast - it's an easy way to cook once and have several meals during the week!
Dee Dee (My Midlife Kitchen) says
In my book, anything with mashed potatoes is a winner! I love how they help all of the other ingredients cling to each other, and taste so good--even when they're leftovers!
Marye Audet says
I totally agree!
Danielle | The Creative Bite says
My husband is all about meat and potatoes, so he would pretty much be obsessed with this hearty dish!
Marye Audet says
🙂 Mine is definitely a meat and potatoes guy and he likes it. 🙂
Debbie says
I don't usually make comments. My husband I enjoyed this so much that I had to let you know! It is hard to come up with what to do with that little bit of leftover roast beef. This is just simple comfort food. Hubbie said it is a KEEPER! Thank you for Sharing., I have Shared it too.
Jenny B @ Honey and Birch says
What a great way to use up leftovers! I love it. And I love the idea of reclaiming mealtime - we are guilty of eating with the TV on and our cellphones nearby. It would be nice to eat together and talk to each other - I remember meal times when I was a kid and there weren't cellphones yet. It was nice. 🙂
Christie says
I love finding recipes to make leftovers into something else entirely. What a delicious use for pot roast.
