Preheat your fire for high heat direct grilling (around 450F).
Add your center cut beef tenderloin, unseasoned, to the grill to sear on all parts for 30-45 seconds until the outside is completely browned. Once done, pull off and slice into ¼” - ½” thick filets. Set aside until ready to cook.
Add a cast iron skillet over the flames with your clarified butter or ghee. Bring the butter up to 400F, then add the oregano, rosemary, parsley, thyme and red chili flakes. Mix together and pull off the grill.
Add another cast iron skillet or wok to your fire. Add 2 tbsp of your melted butter to the skillet and bring up to high heat.
In the center, add tomatoes and smashed garlic. Let simmer for 1-2 minutes, then carefully add your sliced tenderloin filets all over the skillet.
Let the steaks simmer for 2-3 minutes while you baste them in the simmering hot butter & herbs mixture.
Once the steak is 120F, pull it off and let cool.
Serve with the garlic, tomatoes, chopped parsley and a dusting of coarse sea salt. Enjoy!
