Take the roast out of the fridge about 1-2 hours in advance.

Step 2

Tie the roast for even cooking.

Step 3

Preheat the oven to 450 degrees Fahrenheit.

Step 4

In a bowl, combine mayonnaise, kosher salt, Rosemary, thyme, garlic cloves, and black pepper and stir until incorporated. Rub this mixture all over the roast.

Step 5

Place roast in a roasting rack with the fat cap side up.

Step 6

Bake roast at 450 degrees Fahrenheit for 20 minutes.

Step 7

Reduce heat to 325 degrees Fahrenheit and cook the roast for at least an hour, until the middle of the roast reaches your desired temperature. See notes for temperature to remove roast from oven.

Step 8

Once the appropriate temperature is reached, remove the roast from the oven and cover roast lightly with foil. Allow the roast to rest for about 20 minutes before carving.
