Grilled Pork Tenderloin

We use our outdoor grill pretty much year round, but there is something to be said for hanging out in the backyard in the summertime, soaking up that late afternoon sun and cooking a delicious meal. It’s too hot to turn on the oven, and who wants to be slaving over a hot stove when there is outdoor fun to be had? Enter this juicy grilled pork tenderloin.

I always marinate pork tenderloin because it helps the meat become even more tender and so juicy and really infuses flavor into the meat. I also made a fresh, bright chimichurri sauce to drizzle over the top adding even more flavor. You don’t “need” a sauce, but we love this herby, bright sauce with pork tenderloin and steaks.

How to Make Grilled Pork Tenderloin

  1. Combine lemon juice, olive oil, garlic, paprika and oregano in a ziploc bag. Place the pork tenderloin in the bag, shaking to coat the whole tenderloin and massaging the marinade into the meat. Refrigerate for at least 30 minutes and up to 4 hours. PRO TIP: do not marinate meat in lemon juice for longer than 4 hours or the acid will begin to break down the muscle. If you need to marinate overnight, leave out the lemon juice and just add it 30 minutes before cooking.
  2. When you are ready to cook, pre-heat your outdoor grill to medium-high heat (about 500 degrees F). Place the marinated meat on the grates over the flame and cook for 15-20 minutes, turning a few times to char all sides.
  3. Transfer the grilled pork tenderloin to a plate and tent it with foil to let it rest for 5-10 minutes before slicing into 1-inch thick medallions and serving.

What is the best temperature for pork tenderloin?

It is recommended that you cook all cuts of pork (tenderloin, chops, roasts) to an internal temperature of between 145 and 160 degrees. Pork tenderloin is medium rare at 145 degrees, and light pink in the center, keeping the meat nice and juicy. There is no need to cook it to well done as it is perfectly safe at 140-145 degrees.

How to make Chimichurri Sauce

A chimichurri sauce is made from finely chopped parsley, minced garlic, olive oil, finely chopped green onions, red pepper flakes, and red wine vinegar. Combine all of the ingredients together in a small bowl and store in a sealed container until ready to serve. Serve with the grilled pork tenderloin.

Chimichurri will last at least 3 months in the fridge if properly stored. You could also freeze the sauce into cubes and store indefinitely.

Serving suggestions

What to do with leftovers

Place leftovers in an airtight container in the fridge for 3-5 days. My favorite use for leftover pork tenderloin is to chop it into bite-sized pieces and mix it into my easy egg fried rice.

To freeze, place in a freezer bag and keep frozen for up to 6 months.

Meat should register 145 on a meat thermometer at the thickest part of the meat. *Note: if meat is not fully cooked but charred all around, additional cooking time in a 400 degree oven may be required to reach desired internal temperature.
  • Transfer the pork to a plate and tent with foil. Allow to rest 5-10 minutes. Slice into 1-inch thick medallions and serve immediately, topped with chimichurri sauce.
