Ingredients

  • 2.5 lb pork tenderloin 2 tenderloins, 1120 g
  • 2 Tbsp. apple cider vinegar 30 g
  • 3 Tbsp. grainy mustard 45 g
  • 6 frozen garlic cubes or minced cloves
  • 1 Tbsp. pure maple syrup 15 g
  • 1 Tbsp. kosher salt
  • 1 Tbsp. dried rosemary
  • Kosher salt for grilling

Instructions

  • Trim any fat and silver skin off of the pork tenderloins and place in a large dish or resealable bag. Mix together the rest of the ingredients for the marinade and pour over the pork. ​​You can cover, and refrigerate for a few hours or overnight— OR just leave it on the counter like I did for 15-30 minutes before grilling if you’re in a pinch! Of course the longer marinade the better. But pull it out of the fridge about an hour before grilling to let it come to room temp before grilling.
  • Grill: Heat grill to pretty high heat. Spray grill carefully with cooking spray. Sprinkle tenderloins with additional kosher salt and pepper and place on the grill. Sear for about 2-3 minutes per side over the high heat, and then turn down to medium, and cover. Cook for about 15-17 minutes TOTAL, including searing time, rotating every 5 minutes or so. If you have a meat thermometer, internal temp should be about 140. Let rest for 10 minutes, tented with foil before slicing in!
  • Air Fryer: Pull it out of the fridge 30-60 minutes before you cook to bring it to room temperature. Sprinkle the tenderloins all over with a good fresh pinch of kosher salt and place in a preheated air fryer at 400 degrees. Cook for about 20 minutes, turning half-way through. Check the temperature at 17 minutes or so and pull when you’ve reached an internal temp of 145!*
  • Oven: Bake at 400 for about 20 minutes, until it reaches 145. You won’t get the pretty color you get grilling or air frying. But it’s still delicious. You can also sear on our stove top first for the color and char on the outside, and finish for 10-15 minutes in the oven. A meat thermometer makes that perfect internal temp much easier!
