Trim excess fat (but not all of it) off the steaks and set aside.
In a small bowl, combine half of the olive oil with garlic salt and black pepper.
Rub olive oil mixture all over the steaks.
Heat remaining olive oil in skillet over medium-high heat until shimmering. Add red onion and saute for 1-2 minutes to soften.
Add liquid smoke and Worcestershire sauce to skillet and bring to a boil. Cook until liquid reduces a bit. Remove from skillet and place in a large mixing bowl.
To that mixing bowl, add blue cheese and bread crumbs. Pour in the very softened butter.
Use gloved hands to gently combine all the ingredients in the bowl.
Heat remaining olive oil in skillet over high heat until shimmering. Add the steaks and sear well on both sides, about 3-4 minutes each.
Remove from heat and top steaks generously with the blue cheese mixture. You will have some left over.
Place skillet into preheated oven and cook for 5 minutes. Turn oven up to broil, broil for 1 minute.
Remove skillet from oven and immediately move steaks to a cutting board. Tent with foil and allow to rest for 5-10 minutes before serving.
Top or serve with remaining blue cheese mixture if you like. TIP - Be sure to remove the steaks from the skillet right away. If you leave them in the hot skillet, they will continue to cook turning your medium-rare steak into medium-well.
