For the best results, choose a high-quality pork tenderloin from Whole Foods or a trusted butcher. Look for tenderloins that are about 1-1.5 pounds for even cooking. Fresh rosemary makes a big difference here—farmers markets often have the best bunches. If you’re using dried rosemary, reduce the amount to one-third.

No apple cider vinegar? White wine vinegar or lemon juice works as a substitute. For a spicy kick, increase the red pepper flakes to 0.5 teaspoon. If you prefer a sweeter marinade, add an extra 1 tablespoon of honey. The garlic can be adjusted to taste, but don’t skip it entirely.

This marinade keeps well in the fridge for up to 5 days. Store leftovers in an airtight container and reheat within 3 days. The cooked pork tenderloin freezes beautifully for up to 3 months—just thaw overnight in the fridge before reheating.

Step-by-Step Instructions for Grilled Pork Tenderloin

Follow these straightforward steps to achieve perfectly grilled pork tenderloin every time.

Step 1: Prepare the Marinade

In a blender or food processor, combine the 0.25 cup olive oil, 4 cloves garlic cloves, 2 tablespoons fresh rosemary, 2 tablespoons dijon mustard, 2 tablespoons apple cider vinegar, 1 tablespoon honey, 1 teaspoon salt, 0.5 teaspoon black pepper, 0.5 teaspoon paprika, and 0.25 teaspoon red pepper flakes. Blend until smooth and well combined. The marinade should have a vibrant green color and a fragrant aroma.

Place the 1.5 lb pork tenderloin in a large zip-top plastic bag or a shallow dish. Pour the marinade over the pork, turning to coat evenly. Seal the bag or cover the dish with plastic wrap. Refrigerate for at least 2 hours or overnight, turning occasionally.

Step 2: Preheat the Grill and Prepare the Pork

Preheat your grill to medium-high heat, around 400°F. Remove the pork tenderloin from the marinade, letting any excess liquid drip off. Pat the pork dry with paper towels to promote even browning.

The grill grates should be clean and brush them with oil to prevent sticking. I use a paper towel dipped in olive oil and held with tongs to oil the grates.

Step 3: Grill the Pork Tenderloin

Place the pork tenderloin on the grill, rotating it to get a nice sear on all sides. Close the grill lid and cook for 15-20 minutes, turning every 5 minutes, until the internal temperature reaches 145°F for medium doneness. Use a meat thermometer to check the internal temperature, inserting it into the thickest part of the tenderloin.

Once cooked, transfer the pork to a cutting board and let it rest for 5-10 minutes. The internal temperature will rise slightly during this time. Slice the pork into 1-inch thick medallions and serve immediately.

Step 4: Serve and Enjoy

Slice the rested pork tenderloin against the grain into 1-inch thick slices. Serve with your favorite sides, such as grilled vegetables or a fresh salad. The pork should be juicy and tender, with a nice char on the outside.

For the best experience, serve immediately while the pork is still warm. You can also drizzle any accumulated juices from the cutting board over the sliced pork for extra flavor.
