Juicy Pork Tenderloin for Dinner Starts with An Easy Marinade!

Since it’s lean, pork tenderloin can tend to be dry and flavorless, however, this effortless, 5-ingredient marinade completely changes that! The ingredient list is surprisingly simple, yet the results are AMAZING, producing a sweet and savory marinade that turns into a glaze when cooked (similar to teriyaki chicken marinade, just less sweet). Plus, there’s no chopping involved – all you have to do is whisk together the oil, soy sauce, brown sugar (or honey), Dijon mustard, lemon juice, garlic, and salt; and let the marinade do all the hard work transforming the pork. 

And like many of my other easy marinade recipes, you can let pork tenderloin marinate longer because it’s a larger piece of meat, meaning you can prep it in the morning, and it’s ready for cooking on the grill or in the oven when you get home for the day. In fact, the pork turns out better the longer you marinate (up to 12 hours) as it allows the flavors to deepen. Once it’s cooked, don’t forget to let the meat rest for at least 5 minutes to allow the juices to reincorporate into the meat – this is key to juicy meat! Can’t get enough of 5-ingredient recipes? You have to try this curry chicken marinade, too!

Key Ingredient Notes & Substitutions

  • Soy Sauce: Use tamari for gluten free.
  • Brown Sugar: Use the same amount of honey instead of brown sugar if you’d like, though I preferred the flavor of brown sugar in testing.
  • Lemon Juice: Freshly squeezed lemon juice is preferred, but bottled will work in a pinch.
  • Pork Tenderloin: I call for 2 pounds of pork tenderloin in this recipe. One tenderloin is usually about 1 pound, so you will need 2 tenderloins. If you only have 1 pound of tenderloin, you can half the marinade recipe.

Ingredients

  • ¼ cup avocado oil, or any neutral flavored oil
  • 3 tablespoons brown sugar
  • 2 tablespoons soy sauce
  • 1 tablespoon Dijon mustard
  • 1 tablespoon fresh lemon juice
  • 2 minced garlic cloves
  • ½ teaspoon kosher salt
  • 2 pounds pork tenderloin, silver skin removed

Equipment

Instructions 

Marinade Instructions

  • Add the oil, brown sugar, soy sauce, mustard, lemon juice, garlic, and salt to a medium bowl. Whisk until smooth and the sugar has dissolved.
  • Set aside 2 tablespoons of the marinade.
  • Pour the remaining marinade along with 2 tablespoons of water into a 1-gallon zip-top bag or baking dish.
  • Using a fork, lightly poke holes all over the pork tenderloin, then add to the bag or dish, press as much air out of the bag (if using) as possible, or cover with plastic wrap (if using a baking dish). Refrigerate for at least 30 minutes, or up to 12 hours, flipping occasionally.

Grilling Instructions

  • Heat a grill to medium-high. Allow to preheat for 15 minutes. Remove the pork tenderloin from the marinade, shake off any excess, and discard any remaining marinade from the bag or dish.
  • Grill, with the cover down, until the internal temperature registers 145F (medium rare) or 160F (medium), about 5-7 minutes per side.
  • Remove to a cutting board and allow to rest for 5-10 minutes. Slice against the grain into 1 inch slices, or dice into pieces (if using for taco), serve, drizzled with reserved 2 tablespoons marinade, and serve.

Baking Instructions

  • Preheat your oven to 400°F. Add the pork tenderloin along with marinade to a medium baking dish. If you have a large baking dish or rimmed sheet pan, omit the marinade as it will spread and possibly burn. Bake for 25-35 minutes, until the internal temperature registers 145F (medium rare) or 160F (medium).
  • Remove to a cutting board and allow to rest for 5 minutes. Slice against the grain into 1 inch slices, or dice into pieces (if using for taco), serve, drizzled with reserved marinade, and serve.

Notes

  • Check to make sure your pork is done with a meat thermometer. The National Pork Board recommends cooking pork tenderloin to an internal temperature of 145° F for medium rare and 155° F for medium with a 3 minute rest time.
  • Yields ⅓ cup marinade.
  • Use tamari for gluten-free.
