The term baron of beef is more commonly known as top sirloin roast. This thick cut of meat, also known as London broil, center cut roast or top butt, can be slow-roasted for a tender, juicy result. Cooking length will vary based on the size of the cut and the desired doneness (rare to well-done). For intense flavor, the meat can also be marinated prior to cooking, although the thickness of this cut requires lengthy marination for the flavors to penetrate the meat.
Things You'll Need
Age the baron of beef. This optional step gives your meat a smooth, tender, flavorful texture. Place the beef in the refrigerator on a wire rack with a tray or plate under it to collect the drippings. Leave the meat in the refrigerator for one to four days, then trim any dried pieces of meat off prior to cooking.
Alternatively, marinate the baron of beef in the refrigerator prior to cooking for a juicy, flavorful cut. For a 5 lb. baron of beef, mix 1 cup of teriyaki marinade, 3 tbsp. of Worcestershire sauce, 3 tbsp. of steak sauce and one packet of meat marinade in a plastic bag. Add 1/2 cup each of oil and vinegar, and water sufficient to cover the meat when placed in the bag. Allow the meat to soak in the marinade as long as possible. Alternative marinade solutions include 1/2 cup of soy sauce or honey, 1/4 cup of garlic or 1 cup of red wine. Mix and match to suit your preferences.
Prepare a dry rub for your baron of beef. This can be done for meats that have been aged or marinated, or as a quick flavor fix for an unprepared cut of meat. You can also slice the meat into thin strips, or dry rub the entire hunk of meat. An excellent rub can be made from 3 tbsp. each of onion and garlic powder, cayenne pepper (if you like it spicy hot), brown sugar and paprika, with salt and pepper.
Sear the roast in a frying pan, for six to eight minutes, until browned on all sides. This helps seal the juices into the cut, keeping it from drying out while cooking.
Place the baron of beef in the oven on a wire roasting rack or in a crock pot. Cook to the desired doneness in 250 degree Fahrenheit heat until the inside temperature reaches 110 degrees Fahrenheit. Turn the oven heat to 500 degrees Fahrenheit and cook until the meat reaches the desired internal temperature. A rare baron of beef with a cold center will have 125 degree Fahrenheit internal heat; a well-done roast will have an internal temperature of around 165 degrees Fahrenheit.
Allow the baron to rest under a foil tent for 20 minutes prior to carving.
