Gratin Potatoes

I make this gratin from time to time.... the recipe is in my head.
I was able to find it printed here at recipe zaar

It's from Rosie Daley's cook book.

For a time she was Oprah's chef.

It's delicious and low fat.

Ingredients:
cooking spray


3 medium baking potatoes, thinly sliced


2 tablespoons flour


1 medium onion, thinly sliced


1/8 teaspoon cayenne


1 teaspoon paprika


1/2 teaspoon black pepper


2 tablespoons parmesan cheese, grated


1 small zucchini, thinly sliced


1/4 teaspoon ground nutmeg


1/2 teaspoon spike seasoning


12 ounces evaporated milk ( I believe the original had fat free evaporated milk)


2 tablespoons fresh parsley, chopped


Directions


1 Preheat oven to 400ºF.


2 Coat a 10-inch gratin dish or glass pie plate with 3 sprays of the vegetable oil.


3 Layer 1/3 of the potatoes over the bottom of the prepared gratin dish, overlapping the slices in a spiral  pattern.


4 Over the potatoes, sprinkle 1 tablespoon of the flour and arrange the onion rings.


5 Dust with the cayenne and 1/2 teaspoon of the paprika.


6 Layer another third of the potatoes, adding the remaining tablespoon of flour, the black pepper, and 1 tablespoon of the parmesan.


7 Scatter the zucchini, dusting with the nutmeg and Spike seasoning.


8 Top with a spiral layer of the remaining potatoes.


9 Pour the evaporated milk over the gratin and add the remaining paprika and parmesan.


10 Cover with foil and bake for 45 minutes.


11 Remove the foil, lower to 350ºF, and bake for about 15 minutes more, until the top is golden brown.


12 Remove the gratin from the oven and allow it to cool for 10 minutes.


13 Garnish with the chopped parsley.
