Hachis Parmentier

Step 1

In a medium pot over medium high heat, bring the potatoes to a boil in lightly salted water. Boil until very tender, roughly 15 minutes.

Step 2

Once the potatoes are tender, drain the water and mash them with the warm milk and 3 Tbsp of butter.*

Step 3

While the potatoes are boiling, heat 1 Tbsp of butter in a large sauté pan. Add the onion and garlic and sauté over medium heat until softened, 3-5 minutes.

Step 4

Add the chopped beef** to the onion and garlic mixture. Mix well. Season with parsley and salt and pepper as needed. (The seasoning level here will depend on your roast’s flavor.) Add a splash or two of beef broth if the meat mixture looks dry.

Step 5

Remove the pan from the heat and add the beaten egg. Mix well.

Step 6

Preheat your oven to 400F.

Step 7

Spoon roughly 1 c of mashed potatoes into bottom of greased 8x8 baking dish. Spread to cover the bottom of the dish.

Step 8

Add the meat mixture, spreading to make it even.

Step 9

Top with the remaining mashed potatoes.

Step 10

Sprinkle with Parmesan cheese.

Step 11

Bake the dish for 20-25 minutes, until the cheese is golden and you can see little bubbles coming up the sides (if using a glass baking dish).

Step 12

Let stand for 10 minutes before serving.
