Preheat oven to 400°F. Remove any fat from pork. Using a fork, puncture the pork in several places.
Add all the rub ingredients together in a small bowl and spread on all sides of the pork, pressing firm to really get the rub on the pork.
Using a heavy skillet, heat over medium-high heat and add butter. Allow butter melt then place pork in skillet and sear just until brown, flipping to sear all sides, about 2 minutes. Place skillet in the oven and roast for 20 minutes.
Meanwhile in a small saucepan add all ingredients for honey garlic sauce, except the cornstarch and water. Whisk to combine and bring to a slight boil.
Combine the cornstarch and water to create a slurry and add to sauce. Whisk until slightly thickened. Remove from heat and set aside.
Remove pork from the oven and baste with honey garlic sauce. Place the oven to "HI" broil and broil pork for 3 minutes to allow sauce to caramelize. Let rest 5 minutes covered, slice and garnish with fresh chopped thyme and rosemary.
