Pat the filet mignon steaks dry with paper towels. Sprinkle liberally with salt and pepper. Pan sear. Melt more (plain) butter in an oven-safe skillet over medium-high heat. (I recommend cast iron.) Add the steaks and sear on both sides until browned, flipping only once using tongs. (The steak will not be cooked through at this point.
Thickness: Filet mignon steaks come in a range of thicknesses from 1/2 inch up to 3 inches. Avoid the thinner steaks! The best filet mignon will be at a minimum 1.5 inches thick, preferably 2 inches thick. Color: Choose bright red steak, which means that it’s fresh. Avoid ones that are brown or have dark spots.
Season the filets liberally with sea salt and black pepper on both sides. Arrange the filet mignon steaks in the air fryer in a single layer, so the pieces are not touching or only minimally touching (cook in batches if needed; don’t crowd the basket). Air fry until the filets reach your desired doneness (use a probe thermometer for best results).
