This is a flavorful and tasty presentation of a very tender cut of beef. We made it for a birthday dinner and it was memorable. From Allrecipes.
- Melt butter in a skillet over medium heat. Add the onion, garlic and thyme. Cook, stirring constantly, until onion is tender. Stir in the beef broth, scraping any onion bits from the bottom of the pan, then stir in the port wine. Bring to a boil, and cook until the mixture has reduced to about 1/2 cup. Set aside. This may also be made ahead of time and reheated.
- Preheat oven to 350°F Heat oil in a cast-iron or other oven-safe skillet over high heat. Sear steaks quickly on both sides until brown, then place the entire pan into the oven.
- Roast steaks in the oven for about 15 minutes for medium rare, with an internal temperature of 145°F You may adjust this time to allow the steaks to finish just below your desired degree of doneness if medium is not what you prefer. Remove from the oven. Stir together the bread crumbs and blue cheese. Top each steak with a layer of this mixture.
- Preheat the oven's broiler. Place steaks under the preheated broiler until the cheese topping is browned and bubbly, 3 - 4 minutes. Remove from the oven and let stand for 10 minutes before serving. Serve with warm port wine sauce.
