Chimichurri Pork Tenderloin Recipe: Herb-Infused Brightness With Zero Waste

This chimichurri pork tenderloin recipe delivers restaurant-quality results with minimal effort—juicy, herb-infused pork paired with bright green chimichurri that doubles as marinade and sauce.

The tenderloin cooks in just 30 minutes, while the chimichurri takes 5 minutes to blend, making this a perfect weeknight dinner that feels like a special occasion.

I developed this recipe after realizing how often pork tenderloin went underutilized in my kitchen, and the chimichurri transforms it into something unforgettable.

The secret lies in the chimichurri—a vibrant mix of parsley, garlic, red wine vinegar, and olive oil that tenderizes the pork while adding layers of fresh, herby flavor. Unlike traditional marinades that can overpower the meat, this bright, tangy sauce enhances rather than masks the pork's natural richness.

The tenderloin stays juicy thanks to a simple salt-and-pepper crust, while the chimichurri's acidity cuts through the fat, creating a perfect balance in every bite.

What makes this recipe truly special is its versatility. You can grill the pork for a smoky depth or roast it in the oven for hands-off convenience—both methods yield perfectly tender results.

The chimichurri isn't just for serving; it also works as a marinade, infusing the pork with flavor before cooking. Serve it with roasted potatoes, a simple salad, or crusty bread to soak up every last drop of that bright, herby sauce.

This dish is a celebration of simplicity and flavor, proving that even the leanest cuts of pork can become the star of the meal. The chimichurri's freshness cuts through the richness of the pork, making it a dish that's both elegant and approachable.

Whether you're cooking for a weeknight dinner or a weekend gathering, this recipe delivers professional-quality results with minimal fuss.

Ingredients for chimichurri pork tenderloin

Bright herbs and tender pork create this restaurant-worthy dish with minimal ingredients.

The pork tenderloin is the star here—center-cut, trimmed of silver skin for even cooking. Most butchers will do this for you, but if you're trimming yourself, look for uniform thickness (about 1.5 inches). Whole Foods or Kroger typically carry high-quality pork tenderloins, but check the marbling—lean cuts like this need the chimichurri's acidity to stay juicy. Fresh parsley is non-negotiable; the vibrant green color comes from flat-leaf parsley, not curly. If you can't find it, curly works but yields less volume.

No red wine vinegar? White wine vinegar or apple cider vinegar in a pinch, though red wine vinegar's depth is ideal. The chimichurri's acidity tenderizes the pork, so don't skip it—lemon juice at half the amount works if you're truly stuck. For the garlic, roasted garlic adds sweetness but loses some punch. The red wine in the marinade is optional but recommended; if omitting, add extra 1 tbsp olive oil to compensate. The crusty bread should be stale or lightly toasted to soak up sauce without getting soggy.

Pork tenderloin cooks fast—rest it 10 minutes before slicing or it'll dry out. Chimichurri keeps 5 days in an airtight jar with olive oil on top (prevents browning). The potatoes? Roast them ahead—they reheat beautifully. For leftovers, store pork and chimichurri separately; the acidity in the sauce will continue tenderizing the meat. Freeze chimichurri for up to 3 months—it's even better after flavors meld.

Step-by-step instructions for chimichurri pork tenderloin

Master this technique and you'll achieve perfectly tender pork with vibrant chimichurri that brightens every bite.

In a food processor, combine the 1.5 cups fresh flat-leaf parsley, 6 cloves garlic, 0.5 tsp red pepper flakes, 1.5 tsp kosher salt, and 1 tsp freshly ground black pepper. Pulse until finely chopped but not pureed—you want texture, not a smooth paste. With the processor running, slowly drizzle in the 0.5 cup extra-virgin olive oil until fully incorporated.

Transfer the chimichurri to a bowl and stir in the 0.25 cup red wine vinegar. Taste and adjust seasoning—this sauce should be bright, tangy, and slightly spicy. Cover and refrigerate for at least 30 minutes to let flavors meld. The parsley should release its vibrant green color and the garlic should mellow slightly. This resting time is crucial for developing depth of flavor.

Pat the 1.5 lb pork tenderloin dry with paper towels—this ensures maximum browning. In a small bowl, combine 0.5 cup red wine (if using), 1 tsp kosher salt, and 0.5 tsp black pepper. Rub this mixture evenly over the pork, coating all sides. Place the pork in a shallow dish and pour half of the prepared chimichurri over it, turning to coat.

Cover and refrigerate for 4-6 hours or overnight. The acid in the marinade will tenderize the pork while infusing it with herbaceous brightness. If marinating overnight, remove the pork from the fridge 1 hour before cooking to bring it to room temperature. This ensures even cooking throughout—cold pork in a hot pan leads to uneven doneness.

Preheat your oven to 425°F. Cut the 2 medium russet potatoes into wedges and toss them with 2 tbsp unsalted butter, 1 tsp kosher salt, and 0.5 tsp black pepper. Spread them on a baking sheet in a single layer, cut-side down. Roast for 25-30 minutes until the edges are golden brown and the potatoes are tender when pierced with a fork.

Flip the potatoes halfway through cooking to ensure even browning. The butter will bast them as they roast, creating crispy edges while keeping the interiors fluffy. Remove from the oven and set aside—these will stay warm while you cook the pork. The potatoes should have a caramelized exterior with a fluffy interior that's perfect for soaking up chimichurri.

Remove the pork from the marinade (reserve the marinade for later) and let it sit at room temperature for 10 minutes. Heat an oven-safe skillet over medium-high heat and add 1 tbsp extra-virgin olive oil. Once hot, sear the pork on all sides until deep golden brown, about 2-3 minutes per side. The pork should release easily from the pan when ready to flip.

Transfer the skillet to the preheated oven and roast the pork for 10-12 minutes for medium-rare (or until internal temperature reaches 145°F for medium). The residual heat in the pan will help cook it evenly. Remove from the oven and let it rest for 5 minutes before slicing—this allows the juices to redistribute, ensuring each bite is moist and tender.

Slice the pork into ½-inch thick medallions and arrange on a platter. Spoon the reserved chimichurri marinade over the top, allowing it to coat the slices. Serve immediately with the roasted potatoes and 8 slices crusty bread on the side. The chimichurri should glisten on the pork, its vibrant green color contrasting beautifully with the golden meat.

Each bite should deliver perfectly tender pork with bright, herby chimichurri that cuts through the richness. The potatoes add a satisfying contrast in texture, while the crusty bread soaks up any remaining sauce. This method ensures zero waste—every herb and scrap is used, from the chimichurri to the potato skins.

Perfect pairings for this chimichurri pork tenderloin

Herb-Infused Wine Pairings

Argentinian Malbec is my go-to wine for this dish—its bold fruit notes and smooth tannins complement the chimichurri's brightness without overpowering the pork. A 2018 Mendoza Malbec from Catena Zapata has just the right balance of earthiness to stand up to the herby sauce.

For something lighter, try a crisp Sauvignon Blanc from New Zealand, like Cloudy Bay, which cuts through the richness with its citrusy acidity. 🍷

Craft Beer Contrasts

A Belgian witbier like Hoegaarden adds a refreshing contrast with its coriander and orange peel notes. The effervescence cleanses your palate between bites of rich pork. For a hoppier option, a session IPA from New Belgium (like Fat Tire) brings a citrusy brightness that mirrors the chimichurri.

Avoid heavy stouts—they'll muddle the dish's delicate flavors.

Classic Side Dish Upgrades

Swap the standard potatoes for truffle-parmesan roasted fingerlings—toss halved fingerlings with 1 tbsp truffle oil, ¼ cup grated Parmesan, and 1 tsp thyme. Roast at 400°F for 25 minutes until caramelized.

The earthy truffle enhances the chimichurri's herbal notes. For a lighter option, serve with shaved fennel salad—thinly sliced fennel tossed with lemon zest, olive oil, and toasted pine nuts. ✨
