That looks great. I love Shepherds Pie. The version my family makes is very similar but the beef goes in the bottom by itself then cans of corn are poured over in a middle layer before the taters are on top. I’ll try it like you did next time.
This is the perfect time of year for it. I can verify for my Texas brothers, if you shovel snow for a couple hours, a bowl of ShepPie may well be remembered as the best food you ever ate.
