Learning How to Cook Filet Mignon in the Oven is easier than you might think and gives you a perfectly tender, restaurant-quality steak at home. With filet mignon, a cast iron skillet, butter, and simple seasonings, you’ll sear for a flavorful crust and finish in the oven for a juicy, foolproof result.
Remove steaks from the refrigerator 30-60 minutes before cooking to bring them to room temperature.
2 6-8 ounces filet mignon steaks
When ready to cook, add a large cast iron skilletto the oven and set the temperature to 450 degrees.
While the oven is preheating, sprinkle filets liberally with coarse ground salt and black pepper on both sides. Drizzle each steak with a few teaspoons of oil, rubbing it in to coat the filet completely.
1-2 tablespoons oil, Salt and black pepper
Once the oven reaches temperature, remove the skillet and place over medium-high heat. Add prepared steaks to the dry skillet and cook for 2 minutes, undisturbed. (The skillet may be smoking slightly- that’s ok!) Flip the steaks and cook for 2 more minutes.
Transfer skillet to the oven and cook for 3-4 minutes for a rare steak (pull out at 120 degrees), 5-6 minutes for medium (pull out at 130 degrees), and 7-8 minutes for medium-well (pull out at 140-145 degrees.) Use a meat thermometer for the most accuracy.
Cooking time: Remember, cook times will vary based on the thickness and size of the steak. These times are based on a 6-8 ounce steak that is 1.5” thick.
Skillet: Cast-iron skillets can tolerate high heat, plus they get better and acquire more flavor with time.
Size: When selecting your cuts, be sure to pick ones uniform in width and thickness so they cook evenly.
Seasoning: Coat the steaks liberally with a combination of sea salt and course black pepper. You pretty much can't go overboard here!
