2 Tsp. Olive oil
3 to 4 Lb. Top sirloin beef roast
1 1/2 Cups Low sodium beef broth
3 Tbsp. Prepared horseradish
3 Tbsp. Sour cream
Heat olive oil in a heavy cast iron skillet over medium heat. Quickly sear the roast on all sides. It takes about 30 to 40 seconds to sear each surface. Remove from heat, transfer roast to a baking pan with a rack. Bake for about 30-40 minutes per half-pound in a 325 oven. When roast has reached desired state of doneness, remove from oven and let stand 15 minutes. Heat broth on high in microwave for 3 minutes. Mix horseradish and sour cream. Slice roast and pour broth over roast. Serve horseradish cream on the side.
