Caramelized Onion Mashed Potatoes:
4 potatoes, peeled and quartered
1 tablespoon kosher salt
4 tablespoons butter, plus 2 tablespoons butter
1/2 cup heavy cream
2 yellow Spanish onions
2 tablespoons butter
Salt
Directions
- Remove all fat from the lamb top rounds and discard. Combine rosemary, thyme, garlic, and 1/8 cup canola oil. Marinate lamb in herb-garlic mixture, covered and refrigerated, overnight.
- For the Lamb Fennel Essence: Trim lamb scraps and dice into 1/8-inch cubes. Heat canola oil until just smoking. Pan fry lamb in batches. Cook until lamb is evenly caramelized dark brown, but not burnt. Strain off fat and de-glaze pan with vinegar and scrape fond from bottom of pan. Add thyme, fennel seeds, and red wine to pot. Reduce. Add demi-glace and simmer very slowly for 2 to 3 hours.
- Add water to bring sauce up to original volume as needed. Reduce by half and season with salt. Strain through fine chinois. Adjust seasoning.
- To finish, bring one cup of sauce to boil. Whip in two tablespoons of cold butter and check seasonings.
- For The Lamb: Preheat oven to 450 degrees F.
- Remove lamb from marinade. Season well with salt. Sear the lamb over high heat with one tablespoon oil in ovenproof pan. Sear to a dark brown, then turn lamb over, and transfer to the oven for 7 to 10 minutes, for medium rare. Remove from oven, cover with foil, and allow to rest for 5 minutes before slicing.
Caramelized Onion Mashed Potatoes:
- Place potatoes and salt in a large pot. Add cold water and cover. Bring to a boil. Reduce to a simmer and cook until completely tender, about 30 minutes. Drain well in a colander.
- Combine 4 tablespoons butter and cream in a saucepan over low heat and heat until butter is melted.
- Peel onions and slice thin as possible. To very hot skillet, add 2 tablespoons butter, then onions, and salt. Stir and continue to cook over high heat until they color. Then reduce heat and caramelize to a chestnut brown color.
- Mash the cooked potatoes into the pot they were cooked in. Keep potatoes warm over a very low flame, stirring in the cream and butter and onion mixture. Taste and adjust the seasonings.
