Preheat your wood-pellet grill to 225°.

Season the steak liberally with salt and pepper.

Place the steaks on the preheated grill, close the lid, and let cook until the steak is 10 degrees under your desired finished temp. See notes below for chart on when to pull it off.

In a large cast-iron skillet placed on the stovetop, heat the pan over high heat.

Place a teaspoon of butter in the pan and immediately place the steak in.

Sear on both sides for 1-2 minutes.

Remove from the stove, reduce the temperature of the stove to medium, and add in the bourbon sauce ingredients. Whisk and cook for 2-3 minutes and pour over the steak.
