Ingredients
- 2 pounds beef roasting joint (rib or sirloin)
- 3 sprigs fresh rosemary sprigs
- 4 cloves garlic cloves, minced
- 3 tbsp olive oil
- 1 tsp sea salt
- 1 tsp black pepper, freshly ground
- 1/2 cup sour cream
- 2 tbsp prepared horseradish
- 1 tsp lemon juice
- 1 tbsp chives, finely chopped
Instructions
- Step 1: Preheat your oven to 275°F (135°C). Pat dry 2 pounds of beef roasting joint and rub it with 3 tablespoons olive oil, 4 minced garlic cloves, 1 teaspoon sea salt, 1 teaspoon freshly ground black pepper, and the leaves from 3 sprigs of fresh rosemary, pressing the mixture into the meat.
- Step 2: Place the beef on a roasting rack inside a roasting pan and slow-roast in the oven for approximately 2.5 hours, until the internal temperature reaches 130°F (54°C) for medium-rare; tent with foil and rest for 15 minutes before slicing.
- Step 3: Meanwhile, in a small bowl, combine 1/2 cup sour cream, 2 tablespoons prepared horseradish, 1 teaspoon lemon juice, and 1 tablespoon finely chopped chives. Mix until smooth and refrigerate until serving.
- Step 4: Slice the rested beef against the grain into 1/4-inch thick slices and serve with a dollop of the horseradish cream alongside steamed vegetables or roasted potatoes.
