- 1 6- to 7- pound bone-in or boneless leg of lamb
- ¼ C extra virgin olive oil
- ¼ C Dijon mustard
- 3 garlic cloves finely chopped
- 1 T fresh rosemary chopped
- 1 T parsley chopped
- 1 T sage chopped
- 1 medium onion coarsely chopped
- 1 celery rib coarsely chopped
- 1 carrot thinly sliced
- ½ C dry red wine
- 2 T tomato paste
- 1 C veal demiglace
- 2 T butter
- 1 C water
- Salt and freshly ground pepper to taste
-
Preheat the oven to 375°F. In a bowl, mix 2 T of the olive oil with the Dijon mustard, garlic, and herbs. Coat the lamb with the mixture and season with salt and pepper.
-
Put all the chopped vegetables in the bottom of the roasting pan and coat with the remaining oil. Place lamb, fat side up, on the vegetables and roast for 1 hour and 40 minutes or until the internal temperature reaches 130°F.
-
Remove from oven and set lamb aside to rest for 15 minutes.
-
Set the roasting pan over two moderately high heat stovetop burners and pour in the wine. Reduce to about ¼ C while scraping the brown bits on the bottom. Stir in the tomato paste and simmer for 1 minute. Add the demiglace, butter, and water and simmer, stirring occasionally, until the sauce is reduced to 2 C, about 5 minutes. Strain the sauce into a small saucepan, pressing on the solids. Season with salt and pepper and keep hot.
-
Carve the lamb and serve the slices with the red wine sauce.
