Step 1

Remove filets from fridge and season to taste with salt and pepper, let come to room temperature

Step 2

Pre-heat oven to 400 degrees

Step 3

About 15-20 minutes before cooking filets, place cast iron skillet into oven

Step 4

Remove hot pan from oven, place on burner over medium high heat, add some cooking oil, I typically use a little avocado oil plus butter

Step 5

Once butter has melted, place steaks into sizzling hot pan and let sit for 7-8 minute, until it develops a nice brown crust

Step 6

Turn steaks over and place pan into oven, using a glove or towel, for another approx. 7 or so minutes

Step 7

For medium rare Filet Mignon, remove steaks from oven when internal temperature reaches about 120 degrees, they will rise a few more degrees after taking them out of the oven
