Ingredients

  • 1 1/2 lbs corned beef cooked, sliced thin
  • 1 Russet potato large, sliced 1/4" thin
  • 2 cups milk
  • 2 tbsp butter
  • 2 tbsp of flour
  • 4 shallots sliced thin
  • 3 cups Brussels sprouts sliced thin
  • 1/2 cup Parmesan cheese

Instructions

  • Preheat oven to 425°F. Coat a 9x9” casserole dish with oil or butter, set aside.
  • Using a mandolin or knife slice the potato into 1/4 inch slices. Slice the cooked corned beef thin and set aside. Slice the shallots and Brussels sprouts thin and set aside.
  • In a large saucepan add the sliced potato and cover with milk and butter. Bring to a boil, lower heat and simmer 8 minutes. Turn off heat and allow to cool, enough to handle. Reserve the milk and butter, set aside.
  • Layer the potato then the corned beef slices, shallots and Brussels sprouts. Repeat again using all ingredients.
  • Whisk the flour into the milk and pour milk over all and top with Parmesan cheese. Bake for 50 minutes. Top will be a deep, crispy brown. Allow to cool at least 15 minutes before slicing to set and serve.

Notes

If you're converting meat from a slow cooker to an Instant Pot, follow this rule: if the meat dish cooks in eight hours on low or four hours on high in the slow cooker, it will cook in 25-30 minutes in the Instant Pot. Make sure the Instant Pot setting reads "sealing" and not "venting" to ensure it's cooked properly.
