Instructions

  2. Add the remaining 1/2 tablespoon of butter to the same skillet. Add panko and cook until golden brown and toasted, 1-2 minutes. Remove from the pan and toss with the onions along with the parmesan cheese, salt and pepper. Set aside.

Mushroom Cream Sauce

  1. Heat butter in a medium sauce pan. Add mushrooms and saute for 3-4 minutes or until tender and golden brown.
  2. Add garlic and sauté for 1 additional minute.
  3. Whisk in flour and stir constantly for 1 minute.
  4. Slowly pour in chicken stock and milk. Allow the sauce to simmer stirring constantly until thickened.

Assembly
