Alea’s Roast Beef Shepherd’s Pie

Shepherd's Pie Recipe

This recipe is fast and easy to prepare, especially if you use leftovers from your holiday dinners. Shepherd’s Pie is often made using ground beef, but it is an especially delicious way to use up leftover roast. You can also use leftover vegetables and top it with leftover mashed potatoes if you have them on hand.

If you don’t have leftover mashed potatoes, make mashed potatoes using 4 potatoes and your favorite recipe. I used my Garlic Mashed Potatoes Recipe on top of the Shepherd’s Pie.

Using leftover gravy adds a special depth to this recipe. If you don’t have leftover gravy, you can make a fast and easy cheater gravy and use it instead.

Cheater Beef Gravy


  • 1 cup beef broth
  • 1 tablespoon + 1 teaspoon cornstarch
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 1/4 teaspoon sage
  • 1/4 teaspoon thyme


  1. Combine all of the ingredients in a small pot.
  2. Whisk while cooking over a medium-high flame until the gravy becomes thick and smooth.

You can use leftover vegetables if you have them available, if not use a one pound bag of mixed vegetables. I like corn, peas, carrots and green beans in my Shepherd’s Pie, but it is good with any number of vegetable combinations.

After you spread the mashed potatoes over the top, you can sprinkle cheddar cheese over the top. I chose to sprinkle parsley over the top instead so that my pie would be dairy-free.

    I don’t know what fairy tales you grew up reading but shepherds watch sheep and so shepherds pie is usually made with lamb. Cottage pie is usually made with beef since the cows don’t have to be watched. If you make it with poultry or vegetarian I have no idea what to call it but maybe that is also cottage pie? Thanks for sharing the recipe.

      Jasmine, you of simple mind!
      Shepherd ‘s pie is merely a concoction of layers of meat(any kind) vegetables and topped with mashed potatoes and baked until potatoes are browned or if you put cheese on top, until cheese is melted!
      It is similar to “moussaka ” a Greek dish created from left overs!
      It can be called many things, just as they are many words for ignorant!
