Roast Prime Rib with Gratin Potato

Serves Six
- from David Burke’s New American Classics

5 stalks celery
3 large onions, cut crosswise into 1-inch thick rings
3 large carrots, cut into ¼ inch thick sticks
6 cloves peeled garlic
1 bay leaf
¼ cup olive oil
5-pound prime beef rib roast, trimmed of excess fat
Coarse salt and coarse black pepper
Gratin Potato (recipe to follow)


Preheat the oven to 500 degrees.  Place the celery, onions, and carrots in the bottom of a roasting pan.  Stir in the garlic, bay leaf, and olive oil, stirring until the vegetables are nicely coated.  Generously season the roast with salt and pepper and place it on top of the seasoned vegetables.  Place in the preheated oven and roast for 15 minutes, or just until the meat is beginning to brown.  Lower the heat to 425 degrees and continue roasting for 30 minutes (or perhaps a bit longer), or until an instant-read thermometer inserted into the center reads 120 degrees for rare.  Remove from the oven and allow the meat to rest for 15 minutes.  Remove and discard the bay leaf.  Carve the meat at the table and serve with a wedge of Gratin Potato and the roasted vegetables.

 

Gratin Potato

2 tbsp softened butter
2 tbsp minced fresh chervil
1 tbsp minced fresh thyme
1 tbsp minced fresh tarragon
1 tbsp minced fresh chives
4 cups heavy cream
2 tbsp Roasted Garlic Puree
salt/pepper to taste
6 large Idaho potatoes
4 cups gruyere cheese
½ cup freshly grated Parmesan cheese

Preheat the oven to 375 degrees.  Lightly coat a 10-inch-oval casserole dish with softened butter.  Set aside.

Combine the chervil, thyme, tarragon, and chives in a small bowl.  Set aside.

Combine the cream and garlic puree with salt and pepper to taste in a medium saucepan over medium heat.  Bring the mixture to a boil and immediately remove from the heat.  Keep warm.

Peel the potatoes and cut them lengthwise into ¼-inch thick slices on a mandoline or Japanese vegetable slicer.  Ladle ½ cup of the warm cream mixture into the bottom of the prepared casserole.  Working quickly, make a ring of slightly overlapping potato slices around the perimeter of the prepared casserole.  Continue making slightly overlapping potato rings until the bottom of the dish is entirely covered with potatoes.  Lightly season the top with salt and pepper.  Sprinkle 1 tbsp of the reserved herb mixture over the seasoning.  Using 1 cup of the grated gruyere, make a thin later of cheese over the potatoes.  Ladle 1 cup of cream over all of it.  Continue making layers of potatoes, seasoning, herbs, cheese and the cream mixture until you have made 3 additional layers.  Finish with a layer of Parmesan.  Cover the entire casserole with aluminum foil and place in the preheated oven.  Bake, covered, for 1 hour, or until a toothpick is easily inserted into the center.  Remove the foil and bake for an additional ten minutes, or until the top is golden brown.  Remove the gratin from the oven and allow to rest for 15 minutes to firm up before cutting into serving pieces.
