Cook steaks in the hot pan until beginning to firm and hot and slightly pink in the center about 4 minutes per side for medium. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C). Set aside.

Mix olive oil and butter in a pan over medium heat and allow butter to melt; add onion. Cook and stir until softened and browned 5 to 7 minutes. Add heavy cream blue cheese onion garlic nutmeg and pepper. Reduce heat to medium-low; stir until cheese melts completely 3 to 5 minutes more. Add a little water to thin if necessary. Pour sauce over the steaks.
