Potato Gratin

I recently came to my own blog site looking for a recipe I was sure I had shared in the past.  Shocked not to find it, I have to add it now.  These are a staple in my house.  By now I have basically memorized this recipe, and can throw in curve balls here and there, given what I have on hand in the fridge, and how inspired I'm feeling.  I give you a really smashing, basic Potato Gratin (courtesy of Williams-Sonoma) with slight modifications for helpful hints, and CHEESE.


Potato Gratin

1 1/2 tsp unsalted butter, room temperature
2 lb Yukon Gold or Russet potatoes, peeled, sliced thin (about 1/8")
2 cloves garlic, minced
1 cup heavy cream
1 1/2 cups half and half
3/4 tsp kosher salt
fresh ground pepper
(1/2 cup shredded cheddar/jack cheese, optional)

Preheat oven to 400.  Grease a 2 qt baking or gratin dish with butter.

In a heavy saucepan, over med-high heat, add cream, half and half, garlic, salt and pepper (about 10 twists of a peppermill, or about 1/2 tsp).  Add potatoe slices carefully, making sure they don't stick together as you add them to the pan.  Let mixture reach a boil, then lower heat and simmer for 10-12 minutes, stirring gently (so that you don't break the slices).

Carefully transfer potatoes and cream to baking dish, arranging in layers.  Add generous sprinkle of cheese throughout, and on top (optional).

Bake about 15 minutes, until potatoes are tender, and slightly browned.
