Juicy and succulent filet mignon is perfect for dinner or any special occasion! Tender steak is seasoned, seared, and basted with garlic herb butter. This is a steakhouse-quality recipe that is so easy to make at home!
Allow the meat to sit at room temperature for 20 minutes before cooking, then preheat the oven to 400 degrees Fahrenheit.
In a large cast iron skillet over medium-high heat, add the olive oil. Make sure the skillet is oven-safe. Heat the oil until it's just about to smoke right before the steak is added.
Season the steak with salt, pepper, and Italian seasonings generously on both sides.
Add the seasoned steaks to the hot skillet and cook until seared and browned on both sides, about 2 minutes per side.
Add the butter, garlic cloves, rosemary, and thyme sprigs.
Transfer the skillet to the preheated oven and cook to your liking. Check the temperature of the steaks before placing them in the oven because they may be close to your desired doneness. The steaks will only cook in the oven for less than 5 minutes.
Remove the steaks from the oven when it reaches your desired temperature then baste them with melted butter from the skillet. I like my steak medium-rare, around 120-130 degrees Fahrenheit.
Cover the steaks with foil and allow them to rest for 5 minutes before slicing and enjoying!
