Preheat your oven to 350F.
On a large skillet, that would fit your rack of lamb, heat up your oil over medium-high heat.
Once hot, sear your rack of lamb on each side for about 2 minutes until a good golden crust is formed.
After, place your rack of lamb on a cooking tray and insert a cooking thermometer.
Cook for about 20-30 minutes or until the desired temperature is achieved (see chart above).
Remove from the oven and allow the rack of lamb to rest.
Finally, slice your rack of lamb and serve!
Feel free to combine with my cilantro garlic aioli to give it an extra flavor!
