This recipe combines the rich, earthy flavors of lamb with the indulgent decadence of bone marrow and bacon, all brought together by a flavorful cowboy butter infused with fresh herbs and spices. The slow roasting method ensures a juicy, tender lamb roast, while the crispy bacon and roasted bone marrow add a unique twist.
Ingredients:
- 5 lbs Boneless Leg of Lamb Roast
- Salt, for dry brine
Cowboy Butter:
- Bone marrow from 3 lbs of bone marrow bones
- 3 strips of bacon
- 2 tbsp fresh rosemary, finely chopped
- 1 tbsp fresh thyme, finely chopped
- 1 tsp white pepper
- 1 tsp smoked paprika
- 1 tsp tarragon
- 1 tsp Texas jalapeno salt
Instructions:
- Dry Brine the Lamb:
- Generously season the boneless leg of lamb roast with salt. Place the roast on a rack over a baking sheet and refrigerate uncovered for 48 hours. This will help to enhance the flavor and tenderize the meat.
- Prepare the Cowboy Butter:
- Preheat your oven to 450°F (232°C).
- Arrange the bone marrow bones on a baking sheet and the bacon strips on a separate sheet.
- Roast the bone marrow bones in the oven for about 40 minutes, or until the marrow is softened and bubbling.
- At the same time, bake the bacon for 25-30 minutes, or until crispy.
- Once done, remove the bone marrow from the bones and chop it finely. Finely chop the bacon as well.
- In a bowl, combine the softened bone marrow, chopped bacon, rosemary, thyme, white pepper, smoked paprika, tarragon, and Texas jalapeno salt with softened butter. Mix well to incorporate all the ingredients.
- Prepare the Roast:
- Preheat your oven to 250°F (121°C).
- Generously cover the lamb roast with the prepared cowboy butter, ensuring all sides are coated.
- Place the roast on a rack in a roasting pan to catch the drippings.
- Cook the lamb in the oven at 250°F until it reaches an internal temperature 25°F below your desired level of doneness (e.g., for medium-rare, cook until the lamb reaches about 100°F).
- Finish Cooking the Roast:
- Increase the oven temperature to 350°F (177°C).
- Continue cooking the lamb until it reaches your desired level of doneness (e.g., for medium-rare, about 130°F).
- Remove the lamb from the oven and let it rest for at least 15 minutes to allow the juices to redistribute.
- Serve:
- Drizzle the roast with the pan drippings for extra flavor.
- Slice the lamb, serve with any remaining cowboy butter on the side as a dipping sauce, and enjoy!
This recipe will give you a beautifully tender and flavorful lamb roast, perfectly complemented by the rich, smoky flavors of the bacon bone marrow cowboy butter.
