Loaded Vegetable Shepherd’s Pie with Leftover Roast Beef

By Corinne

Shepherd’s pie is something I don’t make very often, mostly because I rarely make mashed potatoes, so even more rarely have any leftover mashed potatoes to use for the topping. However, I am the owner of a beautiful deep dish pie plate from Pampered Chef, and felt like shepherd’s pie is something that would suit this dish perfectly.

But, when I went to make it, I only had a couple potatoes, so decided to make a mixed vegetable mash for the topping instead of using just using potatoes. This had the side benefit of being both delicious, and probably more healthy as well.

You will need:

  • 2 cups leftover roast beef
  • 2.5 cups peeled, diced potatoes
  • 2.5 cups cauliflower florets
  • 1 cup chopped parsnip (peeled if desired)
  • 1 cup carrot
  • 1 cup peas
  • 1 cup corn
  • 3/4 cup beef broth
  • 2 tbsp corn starch
  • 3-4 tbsp horseradish
  • 1-2 tbsp butter

Preheat oven 400F

Peel and chop potatoes and parsnip. Cut cauliflower into florets. Put potatoes, parsnip and cauliflower into a pot and just cover with water. Bring to a boil, and cook until vegetables are fork tender.

While potatoes, parsnip and cauliflower are cooking, place 2 cups of leftover roast beef, 1 cup of diced carrot (do quite a small dice to ensure the carrot gets cooked!), 1 cup frozen peas and 1 cup frozen corn into a small casserole dish or a deep dish pie plate. Whisk 2 tbsp of corn starch  into 3/4 cup of beef broth and pour over beef and vegetables.

When potatoes, parsnip and cauliflower are fork tender, remove from stove and drain. Using either a hand or stand mixer, whip vegetables together with 1-2 tbsp of butter and 3-4 tbsp of horseradish until smooth.

Top beef and vegetables with the vegetable mash. Cook in 400F oven for one hour, uncovering for the last half hour so the vegetable mash gets some colour.
