Set 2 Filet Mignon steaks out on a cutting board, then coat both sides of each steak with a generous portion of 1 Tablespoon Kosher salt and 1 teaspoon Black pepper. Let the steaks stand for about 10 minutes.
Preheat the grill to high heat. Once it's super hot, place the filets on the grill, then leave them be! Don't touch them for 5-8 minutes. Then flip once, and cook another 5-7 minutes.
Check the temperature of the steaks with a meat thermometer once they've cooked 10-15 minutes. Once it's at the desired temperature, remove from the grill.
Let the steaks rest 10 minutes, then slice against the grain and serve!
Notes
If you have a little more time, salt the filets an hour or two before cooking them, then let them rest uncovered in the fridge until you're ready to grill. This will make the meat even more flavorful!
Right before flipping the steaks, baste them with garlic butter! This will let some fat seep into the meat, which is especially helpful with a very lean steak like filet mignon.
Don't touch the steaks once you set them on the grill except for flipping them and testing the temp! Each time you jostle or squeeze the steaks, they lose precious juices.
Always rest steaks! This lets them come up to temperature and lock in all those delicious juices that would seep out if cut too quickly.
