Shepherd's Pie from Leftover Beef Roast and Mashed Potatoes

Total Time:
1 hr 45 min
30 min
1 hr 15 min

8 servings

  • 1 small onion, peeled and chopped
  • 14 tablespoons butter, divided (1 stick plus 3/4 stick)
  • 1 1/2 pounds leftover pot roast, cubed
  • Salt and black pepper
  • 8 to 10 medium red new potatoes
  • 2 cups milk
  • 1/2 cup sour cream
  • 2 cups instant biscuit mix
  • 1 1/2 cups niblet corn or mixed vegetables, prepared according to package dire

Preheat oven to 350 degrees F.

Pot Roast Layer:

In a large skillet over medium-high heat, saute onion in 2 tablespoons butter. Add pot roast and cook until browned. Season with salt and pepper, to taste. Set aside.

Potato Layer:

Peel and slice potatoes 1/4-inch thick. Place in a saucepan, cover with cold water, and bring to a boil. Cook for approximately 15 minutes or until fork tender. Drain potatoes and transfer to a mixing bowl. Whip potatoes with an electric mixer, mixing until moderately smooth. Don't over beat them; a few lumps are nice. Add 1/2 cup heated milk, 1 stick butter, and sour cream. Season with salt and pepper, to taste. Whip again until mixed. Adjust thickness by adding more milk, if desired.

Biscuit Layer:

Combine biscuit mix and 1 1/2 cups of milk. The mix should be thinner than that of normal biscuit mix but not runny.

Spray a 9 by 9 by 2-inch pan (or any similar casserole dish) with cooking spray. Layer mashed potatoes halfway up the sides of the dish. Next, spread a layer of corn or mixed vegetables on top of the potatoes. Then add the layer of pot roast and onions with gravy. Pour the biscuit mix over the meat. Melt 4 tablespoons of butter and drizzle over top. Bake for approximately 35 to 45 minutes or until top is golden brown. Let stand for a few minutes before serving.

    This is a great way to use up left over pot roast. I already had onions, carrots, & garlic in my pot roast. I only had about a cup of frozen peas so I threw those in. I used instant mashed potatoes because I have a newborn & had no time to make mashed potatoes ( seasoned them with black pepper). I made some gravy because other reviews said that it was dry. I used 1 cup of beef broth, one tbs butter, and whisked in flour/water mixture. I seasoned the gravy with S & P, garlic powder, onion powder & a dash of cayenne. I will be making again despite the fact that this is not traditional Shepherd's Pie!!!1
    Wonderful, I have made this numerous time for friends and family!
    Perfect use of pot roast leftovers. this was my first Shepherd's Pie. I sautéed parboiled carrots and frozen peas along with the beef before layering. I forgot to season the veggies. my bisquick mix was a little too thick, but still good with that butter on top.  
    Next time I'll use instant flake potatoes if I don't have pre-made mashed. and fry the onion and beef in olive oil instead of butter. but i liked the butter drizzled on top of the crust.
    This recipe was fantastic. It was my first Shepherd's Pie recipe, and my entire family loved it (my picky husband & 3 year old son included! I was feeling extra lazy and wanted to throw something together since I had leftover pot roast, so I used box mashed potatoes (yes, the powder ones and threw on frozen corn. It still turned out absolutely freakin' delicious! This one will definitely be a family favorite from now on.
    AMAZING! I used canned baby peas for the vegetable layer because that's what my family likes. I had to use a 9x13 baking dish because it wouldnt all fit in a 9x9. The cheese crust went so well with the beef and gravy, and the potato/vegetable layers underneath rounded this dish out so it felt like you're eating an entire meal. This is for sure going to be a family favorite from now on, GREAT comfort food!
    I made this with left over roast. I loved it. My husband loves this during the winter months when he's been outside all day.
    Delicious! I used half the butter and leftover asparagus and green beans, also added mushrooms. My husband hates leftovers and didn't realize that was what he was eating.
    This was excellent. Used about half as much butter and did not put any melted butter on top. I chopped the meat very small as my youngest daughter does not like roast beef but she ate this all up. I used frozen peas as the vegetable. My husband loved the biscuit like topping. I made extra gravy so that it could be put on each serving as needed. I will definitely make this again.
    This was a fabulous was to use up leftover roast beef! The recipe didn't specify gravy in the ingredients, just when it told you to layer each thing. That was the only thing that we need to do next time, make sure there is enough gravy because it was a little dry. Also, make sure you use a casserole dish with HIGH sides! We didn't have enough room to pour all of the baking mix on top. Thanks Paula for sharing!!
    Another good Paula Deen recipe....but really, you don't need to use all of that butter. I'm sure it would make it taste that much better, but butter isn't cheap and is certainly full of fat and calories! I thought this tasted just fine using about half the butter. Remember to season all of the layers; I forgot to season the vegetables (which were prepared 'according to package directions' and they needed a little salt.
    This was excellent! We practically licked our plates! I made it using good old fashioned pot roast made with onion soup mix and canned mushroom soup, and added a tablespoon of browning sauce to the gravy. And, instead of mixed vegetables, I sliced and roasted carrots in the oven, and added some frozen peas (prepared according to package direction. I used about half the butter in the mashed potatoes, and omitted the sour cream. I sauted the pot roast and onion in a bit of olive oil to make it a little bit healthier. :
    Delicious! This is the first time I made shepherd's pie and I was soo happy with the result I will make it again every time I have leftover pot roast. I didn't have enough gravy so I added the same * ingredients I had to make pot roast yesterday to the sauteed onions and meat. [*ingredients: cream of mushroom soup,red wine,beef bouillon, worcestershire sauce,water. 
    By the way, to some people who had been insisting that Shepherd's pie meat should always be lamb, sorry you are WRONG. I looked it up at Wikipedia. Beef is the most widely- used... but one can use lamb too or whatever meat he chooses. It is also called Cottage Pie.
    This is one of the best shepherd's pie recipes I've tried. Great use of leftovers too. My husband was a happy man! We love it. Never had a bad result from any of Paula Deen's recipes and this is one of our favorites. Thanks Paula!
    The whole family loved it and what a great way to use leftovers!!
    I made Paula's Pot Roast recipe the other day and used the leftovers for this Shepard's Pie. My son and husband couldn't stop raving about how good it was. It was fantastic!
    The entire family loved it. Soul food that was great!
    The recipe looks great - but minus a bit of the butter for ME! but OMG the nasty vein of many comments is deplorable - especially on a RECIPE SITE- get OVER it. If you want to use beef, lamb or any other left over protein - use it. Call it what you wish. Either use or don't the Bisquik - make the recipe your own. But quit sniping at one another - this is for recipe reviews - not a platform for degrading one another! It's a recipe for heaven's sake - either try it if it sounds good - and if not, say "NEXT!
    Made this last night we all liked it. Will make again.
    This was great. I too didn't have any gravy on hand but if you have bouillon and water or a small can of broth you can fix the gravy problem. I browned the meat in a small amt of olive oil then dusted a few tbs of flour over it, added the broth and it made gravy. I added the veggies I had on hand into that as well. Quick to make and was very good. And I have to agree with fanofvlad, shepherds pie does NOT have to be lamb.
    When I cook pot roast there is always gravy so I wasn't surprised to see it in the ingredients. Thanks for the reviewer who gave me the heads up so I knew to save some for this. Another said Shepherd's Pie should be lamb, well not in my family. It has always been beef. Guess my family herded cattle, not sheep.
    I thought this was an easy dinner recipe. It didn't take me long to prepare everything, and I used fresh mashed potatoes because I didn't have any leftovers. It is a little heavy so I wouldn't make it every night of the week, but it's a good way to use up the extra pot roast from Sunday dinner. Plus, my nephews ate it without complaining. (amazing)
    I was also noticing in the recipe that it said to add gravey but there was no gravey in the ingredients. As I was making the mashed potatoes and heating up my left over roast beef I was thinking that this seems like it might be a little dry. SOOOOOO, after scouring my pantry and having nothing to make gravey with, I found a can of cream of mushroom soup. I added the soup to the beef (along with a can of water) while it heated up with the onions. Also for the topping, I took pilsbury refridgerator biscuts and put them on top, as it cooked in the oven, the biscuits puff up and make a wonderful top. IT CAME OUT FANTASTIC!!!!!!
    I think that my husband and I enjoyed this meal more than the pot roast dinner. I cut back on most of the butter and omitted the sour cream and it was still great. I agree that some gravy is a must but I had some leftover anyway. The biscuit topping was excellent and super easy. We look forward to enjoying this meal again soon. Thanks Paula!
    Looking for something to use my leftover pot roast. I was surprised to find gravy in the directions but not in the ingredients. Had pot roast but no gravy. It was too late to turn back. Needless to say the result was a bit dry. Not worth trying again.
    I have made this several times and everyone always lovessssssssssss it.
     I use organic ground beef in place of roast beef amd sprinkle cheddar cheese on top of the biscuits. mmmmmmmmmmmm!!
     My kids love kfc's version of this but they say this is so much tastier. Maybe next time I will use some left over poultry in place of the beef.
    I made this... but used leftover steak. Sort of "garbage" shepherd's pie. I used left over steak, fresh broccoli, hash browns instead of mashed potatoes. It was very good and very easy.
    I was going to make pot roast ( a family favorite) for my son's birthday, but the idea of transporting it made me think twice.Instead I cooked a large pot roast for 6 hours and made two casseroles of this recipe. My family couldn't get enough.They loved the biscuit topping and that it was all in one dish.I made it with the corn niblets as my family is not big on peas and carrots.Paula thanks so much.I love feeding my family and when they can't get enough it's even better.
    Pretty good....agree w/others that it NEEDS gravy. Hey, everything is better w/gravy, right?! The kids even ate it!
    Sheperd's pie is supposed to be from ground leftover lamb but alas many use ground beef which is actually cottage pie. Who ever heard of biscuit mix in Sheperd's pie ? I don't even think the Brits know what that is!!
    This was a great way for our family to use leftover pot roast and green beans! I used instant mash potatoes and it tasted great. Especially easy for a quick weeknight dinner. Give this a try - you'll be happy you did! This isn't the forum for people to vent about whether a recipe is healthy or not or your personal feelings about a chef. Just rate the recipe if you've made. Or else, why are you here? Thanks, Paula!
