Leftover Mashed Potatoes: Cheesy Shepherd’s Pie

With the leftover 4 lbs of mashed potatoes I made Ham & Cheese Croquettes (click here for link to recipe) and I still had enough for this recipe. If you have pre-made leftover mashed potatoes with really is simple even though the ingredient list looks long. Doctor up your mashed potatoes with a bit of garlic powder and black pepper if needed. I have included a recipe for mashed potatoes if needed.

Verdict: Simple, classic, and comforting. On a cold winter night this hits all the right spots. Creamy, cheesy, and savory all at once it was delicious.

Assemble the casserole.

  1. Pour the meat mixture into a 9×9 inch baking dish. Spread it out into an even layer. Spoon the mashed potatoes on top of the meat. Carefully spread into an even layer.
  2. If the baking dish looks very full, place it on a rimmed baking sheet so that the filling doesn’t bubble over into your oven. Bake uncovered for 25-30 minutes.** Cool for 5 minutes before serving.
