How to Make It
Preheat the oven to 475°. Generously coat the roast with half of the chopped herb mixture and season with salt and pepper.
In a large ovenproof skillet, heat 1 tablespoon olive oil over moderately high heat. Add the roast and lightly brown it on all sides, about 3 minutes. Wipe out the skillet, return the meat to it and roast in the oven until an instant-read thermometer inserted in the center registers 110°, about 25 minutes. Transfer the roast to a cutting board and season again with salt and pepper. Cover loosely with foil and let rest for 20 minutes.
Meanwhile, bring a large saucepan of salted water to a boil and fill a bowl with ice water. Blanch the basil in the saucepan for 15 seconds. Transfer the basil to the ice water; drain well and squeeze out all of the excess water. Transfer the basil to a blender. Add the remaining 1/2 cup extra-virgin olive oil and a pinch of salt and blend thoroughly.
Thinly slice the roast and drizzle each portion with 1/2 tablespoon basil oil. Sprinkle with the remaining 1/4 cup chopped herbs and serve.
