Step-by-step
- Preheat oven to 550F.
- Rub roast with salt, pepper and garlic powder.
- Place meat in shallow roasting pan, fat side up.
- Roast for 5 minutes per pound for rare; 6 minutes per pound for medium; 7 minutes per pound for well-done.
- Turn oven off at the end of the cooking time and DO NOT OPEN THE OVEN DOOR FOR TWO HOURS.
- At the end of the 2 hours, remove from oven; slice and serve.
Calculating exact cooking duration relies entirely on total meat mass, requiring precisely five minutes per pound for rare results, six minutes per pound for medium, and seven minutes per pound for well-done at a blistering 550 degrees Fahrenheit. Scaling this roast up or down changes the total thermal energy required to penetrate the interior muscles, but the per-pound multiplier remains constant. Doubling a four-pound roast to eight pounds doubles the active cooking minutes at high heat, yet the residual two-hour oven-off resting phase stays strictly fixed.
High-temperature initial searing denatures surface proteins rapidly, generating robust Maillard compounds while rendering exterior fat caps efficiently. Turning the oven off traps ambient heat inside the cavity, initiating a gradual thermal equalization where muscle fibers reabsorb previously expelled moisture without overcooking the center. Opening the oven door during this crucial two-hour window vents accumulated heat prematurely, disrupting the slow-rising internal temperature curve necessary for uniform doneness from edge to edge.
Dietary preferences frequently demand modifications to the outer seasoning rub, though coarse Kosher salt remains chemically vital for drawing out surface moisture and enhancing protein bonding. Adjusting garlic powder ratios or substituting black pepper with white variants alters aromatic output without interfering with the fundamental thermodynamics of the roast. Selecting bone-in versus boneless cuts alters thermal conductivity slightly, as bone acts as an insulator, though the standard per-pound timing formula reliably bridges minor variations in cut geometry.
