Leftover Turkey Pot Pie Gratin

Preheat oven to 375F.

In a large oven safe enamel deep skillet with a fitted lid, bring the milk, ¼ teaspoon salt or bouillon cube, thyme and sage to a simmer over low heat 5 minutes, until aromatic. Pour into a bowl and set aside. Wipe the skillet.

Melt the butter in the skillet then add the leeks, cook 4 to 5 minutes, until soft. Add the garlic and cook until aromatic, 1 minute. Add the cooked turkey, 1 ¼ teaspoons salt, black pepper, 1 cup of the chicken broth, peas and carrots, 2 tablespoons parsley and thyme and cook 3 to 4 minutes.

Add a ¼ cup cornstarch to the remaining 1 cup chicken broth and mix well, pour over the turkey and cook, stirring until thickened, 3 to 4 minutes, or longer as needed.

Smooth the turkey mixture in the skillet and top with the sliced potatoes starting from the outside, overlapping the potato slices in a spiral until you cover all of the meat. Remove the sage and thyme from the milk and pour over the potatoes, top with Gruyere cheese; cover the skillet tightly with foil or a lid.

Bake on the second rack from the top of the oven, until the potatoes are tender when pierced with a knife, about 1 hour. Remove the lid and broil until the cheese is slightly browned and golden, about 3 minutes. Garnish with remaining parsley.
