I added corn green beans and shredded cheddar cheese to the recipe and used instant mashed potatoes. It was great - a wonderful use for leftover roast beef. Even my husband liked it! I'll definitely make it again. Read More

The onions definitely need to be sauteed prior to putting them into the dish. Even after one hour in the oven they weren't cooked enough. I also incorporated some frozen mixed vegetables for some color. Read More

Outstanding! I fixed this tonight using leftover roast beef from last night's dinner. I sauteed red onions mushrooms and garlic then I placed them over the meat and poured mushroom gravy over the top. Followed by the mashed potatoes. I left the dish covered with foil during the first 30 minutes of cooking. I took the foil off for the last 30 minutes. I'll be making this over and over again! Read More

I didn't have onions on hand so I threw in some onion soup mix with this and this disappeared so fast my head spun! When it comes out of the oven let it set about 10 minutes so it's easier to slice and serves up neater. Brush some butter on top of the potatoes for a crusty top. Read More

I've been making this for over a year now and we LOVE it! I cook my roast in the crockpot on HIGH for 6 hours (so it falls apart). Once shredded I place it on the bottom of the baking dish. I saute onions and mushrooms and place that over the beef. Then the mashed potatoes go over that. Topped off with the juice from the crockpot pot. Delish!! Read More

This is a very quick and easy recipe. Not to mention a great way to use leftovers. Being Irish and growing up eating the food, I have to add that whenever Sheppards Pie is made with any meat other than lamb, its called Cottage Pie. Read More

Huge pot roast and I didn't know what to do with it! This is a great recipe. Prepare for lunch at work! I added 1/4 cup horseradish and scallions to the mashed potatoes for sophistication. I sauteed mushrooms for texture. Read More

Great old fashioned comfort food! I was looking for a way to use up a lot of beef gravy I had made and came across this recipe. I just also happened to have prepared the pot roast (super tender rump roast that had slow cooked all day with a little salt pepper and a can of low-salt beef broth) and mashed potatoes. So all I needed to do was cut up the roast into cubes and slice an onion. I used about 1-1/2 cups of gravy and would next time use a bit more. I assembled it refrigerated it and it was all ready to bake the next day. We all loved it! Thanks! Read More

I made this on a cold rainy night. I used leftover mashed potatoes and used jarred beef gravy. I also added canned string beans. Everyone in my family loved it. I will definitely make this again. Read More
