What You’ll Need

Fragrant garlic and herby thyme balance out the maple syrup’s sweetness and the balsamic vinegar’s tartness. Scroll to the recipe card at the bottom of the post for the exact ingredient amounts.

For the Marinade

  • Blueberries – Fresh or frozen (thawed) work.
  • Maple syrup – Feel free to use agave nectar or raw honey.
  • Extra virgin olive oil – Avocado oil is a good swap.
  • Balsamic vinegar – Reduce the amount by half if you use balsamic reduction.
  • Garlic – Fresh garlic or garlic paste are best.
  • Dried thyme – You can also use dried rosemary.

For the Pork

  • Pork tenderloin – Remove any excess fat.
  • Salt and pepper – Kosher salt and freshly-cracked black pepper are best.

How To Make Blueberry Grilled Pork Tenderloin

The fruity, blended marinade is an easy way to use up leftover blueberries. Scroll to the bottom of the post for the full recipe card.

  • Make the marinade. Blend the blueberries, maple syrup, olive oil, and balsamic vinegar until smooth. Set it aside.
  • Prep the pork. Season the pork with salt and pepper on all sides. Place the pork in a large Ziploc bag. Pour in the marinade. Squeeze out as much air as possible and seal it. Shake well and then refrigerate it for at least 30 minutes.
  • Sear it. Preheat the grill to high. Remove the tenderloin from the bag and discard the excess marinade. Place it on the grill and sear it for 6 minutes on each side.
  • Cook it. Reduce the heat to medium and cook the pork for 15 minutes. Flip it over and cook another 15 minutes. Remove it from the heat and let it rest for 10 minutes.
  • Serve. Slice the pork, serve, and enjoy!

Tips for Success

Butcher’s twine and a meat thermometer are the secret to making a perfectly juicy, grilled pork tenderloin every time.

  • Marinate it longer. The pork can be marinated for up to 12 hours. The longer you let it sit, the more sweetness it can absorb from the mixture.
  • Add tartness. Pour 1-2 cups freshly-squeezed orange juice into the marinade for some natural tartness to brighten up the marinade.
  • Ask the butcher. Reduce prep time by asking your local butcher to remove any excess fat or connective tissue from the pork.
  • Use a meat thermometer. While you can slightly slice into the pork to make sure it’s done, it’s best to stick a meat thermometer into the center. If the internal temperature reads 140F, it means it’s ready. Anything under this and it’s still raw. Over this and it will be over-cooked.
  • Add twine. If the pork is slightly thicker on one end, you can tie it tightly with butcher’s twine to make sure it’s an even thickness throughout. This will help ensure even cooking.

Serving Suggestions

This tender grilled pork tenderloin is perfect for dinner. Pair it with my Grilled Vegetable Plate, Sautéed Brussels Sprouts, or Grilled Asparagus with Onion. For salad options, try my Kale Brussels Sprout Broccoli Salad or Spring Mix Salad with Champagne Dressing. If you prefer soup, make my Mushroom Soup or Creamy Broccoli White Bean Soup.

Proper Storage

This recipe is juiciest the day it’s made, but you can store the leftovers for later.

  • Fridge: Store it in an airtight container for up to 4 days.
  • To reheat it: Sprinkle it with 1/2 teaspoon water and microwave it for up to a minute or until warm. You can also reheat it in a pan over medium-high heat for 7-8 minutes.

  1. Tried this over the weekend. The pork was nice and juicy. However, next time, I will take the leftover marinade and boil it down into a sauce, just for more blueberry flavor. Served it with stuffed zucchini.

    Really good! Grill over indirect heat. I used blueberry jelly, did not add sweetner, added a pinch of rosemary. Simmered excess marinade about 10 min, until thick, to make a yummy sauce!

  3. Mine is marinating in the fridge. Cannot wait to get on the grill. The kids were getting tired of chicken and beef, so I thought this recipe would be a great summer dinner with some veggies from our exploding garden!

    1. My garden has just exploded, with vegetables and weeds 🙂 Hope you enjoyed the tenderloin, I served it at a cookout last weekend and everyone loved it!
