Shepherd'S Pie

Directions

1. 1
   Heat large fry pan on medium heat. Add oil and onions, carrot and celery. Add approximately 1/4 of the kosher salt. Cook on medium heat, stirring frequently, until the vegetables soften (about 10 minutes).
2. 2
   Turn the heat up to medium-high. Add the ground lamb. Sprinkle the meat with another 1/4 of the kosher salt. Stir, breaking up the meat and continue cooking until the meat is nearly browned (almost no pink left).
3. 3
   Remove from heat and spoon off the excess fat.
4. 4
   Return to medium heat. Add the flour to the pan and stir until combined. Allow to cook for approximately 2 minutes.
5. 5
   Stir in the Thyme and Rosemary. Add the broth and the tomato paste. Stir until combined. Allow the mixture in the pan to bubble. It will thicken slightly.
6. 6
   Season with pepper and about 1/2 the remaining kosher salt. Add a dash of Worcestershire Sauce, and pinch of nutmeg. Stir in the frozen peas, remove from heat.
7. 7
   In parallel with the above, boil the potatoes for approximately 10-15 minutes until fork-tender. Drain, reserving 1/2 cup of the water they were boiled inches
8. 8
   Place boiled potatoes in a large mixing bowl. Add butter and remaining kosher salt. Mash with potato masher until all the potato pieces are riced. Add the water and stir until smooth.
9. 9
   Place the meat mixture in a round casserole dish. Top with mashed potatoes. Make sure the potatoes come all the way to the edge and form a seal.
10. 10
    Bake in 400 degree F oven for 30 minutes. It will likely bubble over a bit, so put some foil under it or bake on baking sheet.
