We have a similar technique we use a lot:
Pan Roasted Steaks with Gorgonzola Scallion Butter
1. Steaks MUST be at room temp - al least 30 minutes out of fridge.
2. Oven at 375
3. Heat ovenproof skillet (cast iron) on high heat until pan smokes slightly or a drop of water evaporates on contact.
4. Brush steaks with olive oil and rub with coarse kosher or sea slat and plenty of crushed black pepper.
5. Turn on the vent!
6. Sear for 2-3 minutes per side.
7. Put the pan directly into the oven and roast based on the chart.
8. Spread butter mixture on steaks and let rest for 5 minutes before slicing and serving.

Note: filets will cook 1 minute faster than other steaks. Important to measure the thickness!
Gorgonzola Scallion Butter
1/2 cup unsalted butter, softened
4 oz. Gorgonzola cheese crumbled at room temp.
1/4 cup chopped scallions
1 tsp coarsely ground pepper
1/2 tsp Balsamic vinegar
1. Using a hand-held mixer or mini food processor blend the butter and cheese until smooth. Add the scallions, pepper and vinegar and blend for 1 minute longer until fully incorporated.
2. Lay a piece of plastic wrap on the countertop. Scrape the better into a log. Fold the ends closed and refigerate until ready to use.
