Yes, it sounds much better as Hachis Parmentier, or Shepherd’s Pie. I’ve looked it up of late but remember one version my mother used to make when I was growing up (with canned green beans) and then Hachis Parmentier which was a very involved dish.
I purchased 1.25 lb 96/4 ground round and two large russet potatoes. I peeled the potatoes and put them on to boil while I chopped a few scallions (I’m using up stuff in the frig) and put them on to saute with the beef. I added a small can of whole tomatoes with their broth and about 1T tomato paste, salt, pepper and thyme and cooked it down a bit.
The meat mixture cooled a bit while I sprayed an 8X8 baking dish, then added it. I mashed the potatoes with a bit of milk and butter, making it a bit wetter than it would be because it was going into the oven, 350 degrees for 45 minutes. I did add a bit of grated Parm on top of the meat mixture and on top of the potato layer.
It was quite good for a first try and no recipe to go from at all. The originators of this multi-cultural dish used whatever they had on hand so I didn’t worry about ingredients, only quality and best culinary practices. It was fun! And it’ll be better next time. Cheers, Dee

In the end my fresh green beans were not so much so I added a cup of frozen peas to the meat mixture for a veg instead. If I could trust the oven a broil setting for the last few moments would’ve made the potatoes look prettier but they tasted great as is. Dee
After Z’s N Dallas karate tourney last Nov, he LOVED the shepherd’s pie he ordered at The Londoner…
P came home, refined his recipe over the next few wks, & created a stack for the freezer! (Definitive version has peas, tomatoes, carrots, & mashed potatoes)
I made a base and at the end before baking added some frozen peas that nearly turned out to be British “mushy peas” after baking, but I missed the carrots. Had everything else, though. I believe the French version calls for green beans instead of peas and carrots. I’ll work on mine and perhaps we’ll have a Shepherd’s Pie contest one day!
I love this dish, though I call it Cottage Pie… in the UK it is called Cottage Pie if it has Beef and Shepherds Pie if it has lamb. I use onions and carrots in mine, and the peas a served on the side. Delicious!
I just tried this recipe and let me tell you that my husband love it!! He really like potatos so he was already sold. :)
