Notes

Marinating 
For an extra flavorful roast, marinate it overnight with our Cowboy Butter.
  1. Slather 3 tablespoons of room temperature compound butter all over the roast.
  2. Place meat into a baking dish.
  3. Cover with plastic wrap and refrigerate overnight.
  4. Add a couple of dashes of Worcestershire sauce over the top of the beef just before adding the parsley and garlic mixture.
  5. Roast as per instructions.
Tips
For best results, take the beef roast out of the refrigerator about 10 minutes before cooking.
Take care not to overcook your roast, as it will become dry and chewy.  I like to use a Bluetooth Thermometer with Probe because it helps ensure the steak is done perfectly every time. Be sure to place the thermometer into the center of the meat for an accurate read.
Don't skip resting the meat.
