So we are not vegetarians and I mistakenly thought I had a whole cup of lentils but found I only had 1/2 cup. So since I had about 4 oz of lean ground beef to use up, I also added that. I used beef broth in place of the veggie broth. Otherwise, I stuck with the recipe. Everyone enjoyed this dish but both hubby and I felt it needed just a bit more spice. So next time I plan to add some crushed red pepper to the lentil mix. Yes, this is time consuming and not for a busy weeknight. But there is plenty to make on a Sunday and have again on Monday as left-overs. Will definitely make again.
The lentils and potatoes were both very good individually, and even though the bulgur/mushroom mix was a little too salty I thought the dish as a whole would be really good. It was just ok. Without even comparing it to actual shepherd's pie (which I don't think I've ever actually eaten), it was just...meh. Beginning with the lentils, it took almost 3 hours to put together - even cutting the final bake time in half - so of course the lackluster result was disappointing. Maybe the leftovers will be better. If nothing else I can pirate the individual recipes for the lentils (which taste surprisingly like baked beans) and mashed potatoes. Unless it vastly improves in the fridge I won't be making this again.
I don't usually eat a veg diet, so I was pleasantly surprised with how good this meatless shepherd's pie was. My family ate it with no complaints.
