  • 1 tablespoon brown sugar
  • 1 tablespoon yellow mustard
  • ½ teaspoon salt
  • Dash of pepper
  • 1 (1 lb.) pork tenderloin


  • Preheat oven to 425 degrees F.
  • In a small bowl, stir together first 4 ingredients (brown sugar through pepper).
  • Line a dish or rimmed baking sheet with foil or parchment for easy cleanup. Spray the dish or baking sheet with cooking spray.
  • Place pork on the prepared baking sheet. Pat dry with a paper towel.
  • Rub brown sugar mixture all over the pork.
  • Bake pork for 20-30 minutes, or until a thermometer reads 145 degrees F.
  • Remove from oven, tent with foil, and allow to rest for about 5 minutes before slicing and serving.



  • Be sure that you don't overcook the pork, or it will dry out. I always use a meat thermometer so that I know exactly when the meat reaches 145 degrees F inside. The pork will continue to cook and rise in temperature as it rests, so if you check it and it's close to 145 pull it out and let it finish on the counter.
  • I often use yellow mustard in this recipe, but Dijon mustard also works well!
  • If you're cooking for a larger family of 4 or more, I suggest doubling the recipe and preparing two tenderloins. You can bake them side-by-side on the same baking sheet, so there's no added effort! Just make twice as much mustard glaze. Cooking time remains the same.
  • Prep ahead! You can baste the pork with the sauce in advance and keep the pork covered in the refrigerator until you're ready to pop it in the oven!
