"I like to take the beef out of the fridge about half an hour prior to cooking it. This will ensure the meat to cook more evenly and also prevent the pan from cooling down when frying."

    Season filet mignon on both sides with salt. Turn on the grill function of your oven. Heat an ovenproof pan over medium-high, add some oil, and sear the fillets on both sides. Remove fillets from the pan and let rest in aluminium foil for approx. 5 – 10 min. Remove crust from the fridge and cut to fit the fillets. Place some crust on each fillet and put it back into the pan, crust-side up. Grill the fillets in the oven for approx. 3 – 5 min., or until the crust is browned on top. Set aside.
