Season ribeye steak with 2 teaspoons of Montreal Steak Seasoning, both sides (1 teaspoon per steak).
Using a large cast iron, preheat 2 tablespoons of avocado oil, over high heat (it will be a good time to open the windows right now, and turn ON your stove fan).
Add ribeye steaks and cook on high heat for about 4- 5 minutes, until steaks are slightly charred. Carefully flip on the other side, and immediately add 4 tablespoons of butter, 4 thyme sprigs, 3 garlic cloves and 1 rosemary sprig.
Cook the ribeye steaks on high heat basting with melted butter. Cook for 3 to 5 minutes for medium-rare, 5 to 7 minutes for medium, or 8 to 10 minutes for medium-well (I cook for 5 minutes).
