Prepare the water bath, setting it to 130 degrees for medium-rare. Sprinkle salt and pepper and your choice of other seasonings on both sides of the steaks. Add one steak per sous vide bag, along with a sprig or two of thyme or rosemary (optional). Seal the bags, removing all air
Place the bags carefully into the water, allowing them to submerge fully. Cook for 2-2 ½ hours
Remove steaks from their bags. Pat dry and let rest for 5 minutes. Preheat a skillet with one tablespoon of oil. Then, sear the steaks on each side for 2-3 minutes. Rest on a foil-tented plate for 5-10 minutes prior to serving
