In a medium size bowl mix together the bourbon, maple syrup and soy sauce. Set aside.
Once the steak has come to room temperature, season with salt, pepper and garlic powder.
Heat a large cast iron skillet over medium heat with 1 tablespoon of butter and about 1 tablespoon of canola oil.
Once the pan is hot, sear the steaks on both sides until a nice crust forms. About 3-6 minutes on each side.
Remove from the cast iron and place on a sheet tray with a wired rack on top and bake in the oven on 350°F for about 3-5 minutes until your desired doneness. Remove from the oven and let the steaks rest before slicing.
In the same pan add additional oil if needed and sauté the mushrooms with thyme until the mushrooms are tender. Add in the garlic and continue sauteing.
Turn the heat down to medium low and add in Bourbon mixture, continue stirring until the sauce begins to thicken then remove from the heat.
Spoon sauce over the sliced steak, enjoy!
