What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, with fresh herbs bringing the chimichurri alive. Here’s what you’ll need:

For the Pork Tenderloin

• 1.5 to 2 pounds (700-900g) pork tenderloin – trimmed of silver skin (look for fresh, pink pork with firm texture)
• 2 tablespoons olive oil – for brushing and searing (I prefer extra-virgin for richness)
• 1 teaspoon smoked paprika – adds a subtle smoky depth
• 1 teaspoon garlic powder – for savory warmth
• 1 teaspoon kosher salt – balances flavors perfectly
• ½ teaspoon freshly ground black pepper – for a gentle kick

For the Zesty Chimichurri Sauce

• 1 cup fresh parsley leaves – packed and roughly chopped (flat-leaf works best)
• ½ cup fresh cilantro leaves – optional but adds fresh brightness
• 3 cloves garlic – minced (adds punch)
• 2 tablespoons red wine vinegar – tangy and sharp
• ½ cup olive oil – smooth and fruity
• ¼ teaspoon red pepper flakes – adjust for heat preference
• Salt and pepper – to taste
• Juice of half a lemon – freshens and balances the sauce

Ingredient tips: I recommend using fresh herbs from your local market or garden for the best chimichurri flavor. If you want a gluten-free option, this recipe is naturally gluten-free. For dairy-free or paleo diets, the sauce and pork are naturally compliant. If fresh cilantro isn’t your thing, swap it with extra parsley or fresh oregano.

Equipment Needed

• Grill or grill pan: An outdoor gas or charcoal grill works wonders, but a heavy cast-iron grill pan on your stovetop will also do the trick.
• Sharp knife: For trimming and slicing the pork tenderloin with precision.
• Mixing bowls: One for seasoning the pork, another for whisking together the chimichurri sauce.
• Meat thermometer: Highly recommended to nail perfect doneness (145°F/63°C is ideal for juicy pork).
• Brush or tongs: For turning the pork and applying olive oil.

If you don’t have a meat thermometer, no worries—just watch for firm but springy texture when you press the pork. I’ve also used a budget-friendly instant-read thermometer that’s lasted years and been worth every penny.

Preparation Method

1. Trim and season the pork: Pat the pork tenderloin dry with paper towels. Trim any silver skin for tenderness. In a small bowl, mix smoked paprika, garlic powder, salt, and black pepper. Rub the pork all over with olive oil, then evenly sprinkle the seasoning mixture, pressing it gently into the meat. Let it sit at room temperature for 15-20 minutes to absorb flavors.
2. Prepare the chimichurri sauce: While the pork rests, combine parsley, cilantro, garlic, red wine vinegar, red pepper flakes, lemon juice, salt, and pepper in a medium bowl. Slowly whisk in olive oil until emulsified. Taste and adjust seasoning—chimichurri should be bright and punchy. Cover and set aside to let the flavors marry.
3. Preheat your grill or grill pan: Heat to medium-high (about 400°F/200°C). Oil the grates or pan lightly to prevent sticking.
4. Grill the pork tenderloin: Place pork on the hot grill. Cook for about 4-5 minutes per side, turning to get nice grill marks and even browning. Use tongs, not a fork, to keep juices inside. Total grilling time should be around 20 minutes, but start checking internal temperature after 15 minutes.
5. Check for doneness: Insert a meat thermometer into the thickest part of the tenderloin. When it reaches 145°F (63°C), remove from grill. If you don’t have a thermometer, look for firm but slightly springy texture and clear juices when pierced.
6. Rest the pork: Tent the pork with foil and let it rest for 5-10 minutes. This step is key to juicy results—it lets the juices redistribute instead of running out when you slice.
7. Slice and serve: Slice the pork tenderloin into ½-inch (1.25 cm) medallions. Spoon generous amounts of zesty chimichurri sauce over the top or serve on the side for dipping. Garnish with extra fresh herbs if you like.

If you notice the pork is browning too quickly on the grill but isn’t cooked through, move it to a cooler part of the grill or lower the heat to avoid drying out. Trust me, patience here pays off big time.

Cooking Tips & Techniques

One thing I’ve learned is that pork tenderloin is deceptively easy to overcook, so keeping an eye on that internal temperature is a lifesaver. You want juicy, tender meat, not dry and tough slices. Using a digital meat thermometer has saved me from many a sad dinner.

Another pro tip: don’t skip resting the meat. I’ve made that mistake before, slicing right away and losing all those precious juices. Resting for at least 5 minutes makes a world of difference.

When making chimichurri, use fresh herbs and freshly squeezed lemon juice for the brightest flavor. I sometimes add a pinch of cumin for a smoky twist, but it’s optional. Also, make the sauce ahead of time—it tastes even better once the flavors have melded for 30 minutes or more.

For multitasking, start your chimichurri while the pork is resting. It’s a great way to keep the kitchen moving without rushing. And if you’re grilling outdoors, keep a spray bottle of water handy to manage any flare-ups.

Variations & Adaptations

Want to mix things up? Here are a few ways to customize this grilled pork tenderloin with zesty chimichurri sauce:

• Spicy Chimichurri: Add extra red pepper flakes or a diced jalapeño for some heat kick.
• Seasonal Twist: Swap fresh parsley and cilantro with basil and mint in summer for a fresher, lighter sauce.
• Low-Carb/Keto Version: This recipe is already naturally low-carb, but serve it with cauliflower rice or a crisp salad instead of grains.
• Different Proteins: Try the chimichurri sauce on grilled chicken breasts, flank steak, or even firm tofu for a vegetarian spin.
• Allergen-Friendly: The recipe is naturally gluten-free and dairy-free. For nut allergies, avoid any optional nuts you might add to your chimichurri.

Personally, I once made a batch with smoked paprika swapped out for chipotle powder—gave the pork a nice smoky heat that my husband absolutely loved. Feel free to experiment!

Serving & Storage Suggestions

This grilled pork tenderloin with zesty chimichurri sauce is best served warm, right off the grill. Slice the pork into medallions and spoon the chimichurri over or serve it alongside for dipping. It pairs beautifully with roasted veggies, grilled corn, or a fresh green salad. For drinks, think crisp white wine or a light beer to complement the bright, herbaceous sauce.

If you have leftovers, store the pork and chimichurri separately in airtight containers in the refrigerator for up to 3 days. The pork reheats well in a skillet over medium-low heat to avoid drying out, while the chimichurri tastes even better chilled after a day or two as the flavors meld.

For longer storage, freeze cooked pork slices wrapped tightly in foil and placed in a freezer bag for up to 2 months. Thaw overnight in the fridge and reheat gently. The chimichurri is best fresh but can be frozen for up to a month in ice cube trays for small portions.
