Gather all the ingredients.
Preheat oven to 425F.
Pat dry New York Steak with a paper towel and sprinkle salt and black pepper both sides.
In a small bowl, mix together Soy Sauce, worcestershire, white wine and Swerve/Monkfruit.
Grated garlic with a grater or a garlic press and combine into the sauce. Add butter on top of the sauce. No need to stir or melt.
Add olive oil in a cast iron pan on high heat until lightly smoking.
Once the oil is lightly smoking, place steak inside the pan and cook each side for 2 minutes to sear. Note - Don't move or lift up the steak while searing.
After searing both sides, turn off the heat, pour sauce mixture over the steak and transfer the entire pan into the oven.
Cook steak in the oven for approx 3-7 minutes depending on preference and thickness of the steak. Note - keep in mind the steak will continue to cook after you remove it from the oven, so I usually pull it out 5F before target temp.
Transfer steak pieces onto a plate, pour leftover juices from cast iron pan on top of the steak and serve.
