Key Ingredients for Lemon Garlic Marinated Pork

  • Extra-Virgin Olive Oil: this is the base for the marinade
  • Seasonings: Garlic cloves, lemon zest, fresh rosemary, kosher salt, freshly ground black pepper
  • Pork Tenderloin: Preferably with no salt added solution.

Step By Step Instructions To Make This Grilled Marinated Pork Tenderloin

Step 1: Make seasoning paste

Combine the garlic, oil, zest, rosemary, salt and pepper in a shallow baking dish. Add the pork, turn to coat in the marinade, then cover and refrigerate for 1 to 4 hours.

Step 2: Preheat grill

Preheat the grill to medium-high heat. Brush it down well. Soak a paper towel with oil and set it near the grill with tongs.

Step 3: Grill pork

To grill the pork tenderloin it is best to oil the grill just before adding the pork. Hold the oil-soaked towel with tongs. Drag gently along grill grates, pulling toward you. Immediately place pork on the oiled grill. Cook, turning, every 3 to 4 minutes, until an instant-read meat thermometer inserted into the center of the pork tenderloin registers 138 degrees F, 13 to 17 minutes. (Note: It should rise above 145 degrees as it rests.)

Step 4: Let meat rest & slice

Let the pork rest on a carving board tested with foil, for at least 5 minutes. Slice crosswise into ½-inch thick slices and serve.

FAQs and Expert tips

Storing instructions:

Store leftovers in an airtight container in the fridge for up to 3 days or in the freezer for up to 2 months. Eat leftovers at room temperature or reheat them. Leftover sliced pork is amazing on salads or sandwiches!

Prep ahead!

This pork tenderloin could be prepared up to 24 hours in advance if needed. Add the pork to the marinade and let marinate in the fridge until ready to use. Remove from the fridge 30 minutes to 1 hour before grilling so meat has time to come to room temperature.

Reheating instructions:

Reheat the pork in the oven at 325 degrees F on a rimmed baking sheet until just warmed through, about 10 to 15 minutes. Be careful not to dry out the pork! Alternatively, reheat individually sliced pieces in the microwave for 1 to 2 minutes.

Serving tips!

When serving pork, I like to make a starchy side such as mashed or roasted potatoes and a fresh green salad. I also love making a quick gravy to pour over top.

Can I make this on a grill pan?

I mostly use a standard outdoor grill, but you could also use an indoor grill pan. Make sure to turn your fume hood to high as it will be smoky. Note, the timing will be much longer.

Tips For Perfectly Grilled Marinated Pork Tenderloin

Marinate the Pork Tenderloin Up To 4 Hours: If you plan ahead, refrigerate the pork all slathered in the paste for four hours. That will really impart a ton of flavor. But I also tested it with only an hour of marinating, and that was also totally fine.

Tie the Tail End for Even Cooking

Because pork tenderloins are thin on one side and thick on the other, the thin end becomes dried out while the thick end is still coming up to temp. To help even them out, I tie the thin end. To do this. Tuck the last two or so inches of the tenderloin tail under. Then secure with a single strand of kitchen string. Trim the string so there aren’t any long pieces hanging off because they’ll burn.

Internal Temperature For Grilled Pork

The official recommended internal temperature for pork is 145 followed by a rest. But when I tried that, it was really overcooked. These natural pork tenderloins are only 1 pound- and by the time the center is up to 145 on an instant read thermometer it’s hot all the way through basically, and the carryover takes it way beyond where it needs to be. So I found pulling it at 138 was much better. As you can see in the pics, there is only a faint amount of pink. If you are at all concerned about the safety of the internal temp, I say do what YOU think is best.

Let The Pork Rest

Let the pork rest for 5 to 10 minutes before slicing. This allows the proteins to relax, and will ensure that all the juices don’t flow out when you slice it. It’s an easy way to make the pork even more delicious.

Variations To Try

Next time you want to make a juicy pork tenderloin, try using different marinade ingredients.

  • My favorite garlic marinade is incredibly simple and always a hit
  • If you want something a little different you could marinate the pork in this Maple Teriyaki Marinade with soy sauce and maple syrup instead
  • Instead of marinating in advance grill the pork, then turn it into a sweet bbq pork tenderloin. Simply stir bottled barbecue sauce with a little added brown sugar and then brushed over the grilled pork. Wait until the last couple minutes on the grill so that the sauce doesn’t burn.
  • You could also play around with spice by adding red pepper flakes to the marinade.
  • Adapt this lemon and herb marinade by simply adding other fresh herbs.

What To Serve With Grilled Pork Tenderloin

  • This No-Mayo Potato Salad will make the whole family happy! I love the addition of herbs and sun dried tomatoes. They really make the flavors pop! 
  • My Healthy Coleslaw comes out perfect every single time and is a classic recipe. But if you’re feeling more adventurous, try this blue cheese coleslaw with walnuts. The lemon and rosemary will really go great with the blue cheese. 
  • For a Low Carb side dish, make this Zucchini Ribbon Salad. It’s the perfect meal! Or keep it low key and make a batch of my Apple Cider Vinaigrette and toss it with simple greens. 
  • For desserts try Pineapple Coconut Sorbet in frosted glasses topped with toasted coconut! It’s a great recipe.

Pork tenderloin from factory farms often contains added sodium solution. Not only does this pork come from farms with questionable animal husbandry practices, but the addition of sodium is unnecessary. Look for Certified Organic pork or Heritage pork instead. Check the label and make sure it doesn’t include added sodium.
