  • 1 pork tenderloin about 1 to 1 1/2 pounds
  • Kosher salt and pepper to taste I use 7:2:2

Optional Brine

  • 4 cups water
  • 4 tablespoons kosher salt
  • 3 tablespoons sugar


  • Trim a pork tenderloin of any excess fat and the silverskin.
  • This is the point to brine if you wish. Try 4 cups of water with 4 tablespoons salt. Add 2-4 tablespoons sugar of you want. Refrigerate for 1-2 hours. When done with the brine, remove from brine, rinse under running water and pat dry. You may season some at this point but DO NOT ADD SALT if you brine
  • Brush the grill with oil. Preheat grill to a surface temperature of 450 to 500 degrees. Medium on my super duper grill but medium high on lesser grills. Clean and oil.
  • Place over direct heat. Close lid. Rotate 1/3 every 5 minutes until done to your liking. About 25 minutes for 140. About 30 minutes for 150 (my wife's favorite). Remember, do not cook by time along. Use a thermometer. Time to get to your final temperature varies by weight of the tenderloin, exact surface temperature of the grill and the tenderloin at the start.
  • Remove from grill a few degrees less than your desired final temperature. Tent lightly for 5 minutes before serving.


Pro Tips

  1. Remember it is triangular meat not round. So a flip is 1/3 of a rotation.
  2. Brine if you have time.
  3. Cook over medium grill.
  4. Final internal temperature of 145-150 is nicely done.
