Beef Tenderloin Steak Recipe - Filet Mignon

Ingredients

• 2 6-ounce filet mignon steaks
• salt, to taste
• freshly cracked black pepper, to taste
• 2 tablespoons neutral oil (such as canola or vegetable)
• 2 tablespoons butter
• optional accompaniments: steak sauce, bearnaise sauce, flavored butter, flaky sea salt

Directions

1. About 30 minutes before cooking, remove the steaks from refrigeration and allow them to rest at room temperature.
2. Place a cast iron skillet inside the oven and preheat the oven to 400°F. This will ensure that your skillet is nice and hot when it comes time to sear your filet mignon or beef tenderloin steak. 
3. Season the steaks liberally with plenty of salt and freshly cracked black pepper to taste. 
4. Once the oven is up to temp, remove the cast iron skillet (carefully!) and place it on the stovetop over medium-high heat. Add the neutral oil and wait 30 seconds, then carefully add the steaks.
5. Sear the steaks undisturbed for 2 minutes, then using tongs, flip and sear the reverse side for another 2 minutes.
6. Top each fillet with 1 tablespoon of butter and transfer the entire skillet into the oven. 
7. Roast for 5-6 minutes, until the steaks have reached your desired doneness. If using a meat thermometer, you’re looking for 125℉-130℉ for medium rare.
8. Remove the steaks to a platter and cover loosely with aluminum foil, allowing them to rest at least 5 minutes before slicing and serving with accompaniments of your choice!
