Chimichurri Pork Tenderloin

We marinate pork tenderloin in a simple homemade cilantro chimichurri to give it big, bold flavor. Serve the extra chimichurri on top of the finished tenderloin and it looks and tastes like a fancy restaurant dinner - but it's so quick and simple!

Ingredients

  • 1 cup fresh flat-leaf parsley
  • 1 cup fresh cilantro
  • 3 large garlic cloves
  • 1 small jalapeno pepper diced, seeds removed
  • 1/4 cup chopped white onion
  • 1 teaspoon salt
  • 5 tablespoons olive oil divided
  • 3 tablespoons vinegar
  • 1 pound pork tenderloin

Instructions

  • Add the parsley, cilantro, garlic, jalapeno, onion, salt, 4 tablespoons olive oil, and vinegar to a food processor or blender and process until nearly smooth. If you don't have a food processor, mince everything and then stir in the olive and vinegar.
  • Pour half of the chimichurri into a small dish, cover, and refrigerate until ready to serve.
  • Add the pork tenderloin to a large zip top bag and add the remaining half of the chimichurri to the bag. Coat the pork in the sauce, seal bag, and refrigerate for at least 4 hours.
  • Preheat oven to 425 degrees. Heat a cast iron skillet over high heat.
  • Add the remaining tablespoon of oil to the skillet and heat until shimmering. Add the pork and sear on all sides, about 3 minutes per side, until golden brown.
  • Transfer skillet to oven and bake for 15-20 minutes or until pork reaches 145 degrees.
  • Let rest for 5 minutes before slicing and serving with reserved chimichurri.

Notes

Cilantro: If you're not a fan of cilantro you can easily swap it for more parsley.
Jalapeno: This really isn't too spicy as written, but you can adjust to suit your tastes.
Pork: Tenderloins generally come in a package of 2. Freeze one for later or double the recipe! The leftovers reheat well.
