Sourgrass Pork Tenderloin with Roasted Vegetables Recipe

Sourgrass, or Oxalis, is a fascinating wild plant that's widely available in many regions. Known for its tangy, lemon-like flavor due to the oxalic acid in its leaves, sourgrass is a versatile ingredient that brings a unique zest to dishes. Beyond its delightful taste, sourgrass is packed with vitamin C and antioxidants, making it a healthy addition to any meal.

Identifying Sourgrass

Recognizing sourgrass is straightforward if you know its key characteristics:

  • Leaves: The plant features trifoliate leaves, with each stem bearing three heart-shaped leaflets, much like clover.

  • Flowers: Sourgrass blooms small, yellow flowers with five petals, typically grouped in clusters.

  • Stems: Its stems are often reddish and succulent, adding to its distinctive look.

  • Taste: To confirm you’ve found sourgrass, taste a small leaf. It should have a bright, tangy flavor reminiscent of lemon.

Served alongside a medley of roasted vegetables, this dish is a hearty and satisfying meal that's perfect for any occasion.

Ingredients

For the Pork Tenderloin:

  • 1 pork tenderloin (about 1 to 1.5 lbs)

  • 4 cloves garlic, minced

  • 2 tablespoons olive oil

  • 2 tablespoons freshly squeezed lemon juice

  • 1/4 cup chopped sourgrass leaves

  • 1 teaspoon dried thyme

  • 1 teaspoon dried rosemary

  • Salt and pepper to taste

For the Roasted Vegetables:

  • 2 cups mixed vegetables (such as carrots, potatoes, bell peppers, and onions), cut into bite-sized pieces

  • 2 tablespoons olive oil

  • Salt and pepper to taste

Instructions

  1. Prepare Garlic Herb Mixture: In a small bowl, combine minced garlic, olive oil, lemon juice, chopped sourgrass leaves, dried thyme, dried rosemary, salt, and pepper.

  2. Marinate: Place pork tenderloin in a shallow dish or resealable plastic bag. Pour marinade over it, ensuring even coating. Cover the dish or seal the bag, and marinate the pork in the refrigerator for at least 1 hour, up to overnight for maximum flavor.

  3. Preheat Oven: Preheat your oven to 400°F (200°C).

  4. Season and Arrange Vegetables: In a large mixing bowl, toss mixed vegetables with olive oil, salt, and pepper until well coated. Spread vegetables in a single layer on a baking sheet lined with parchment paper or aluminum foil.

  5. Roast Vegetables: Place baking sheet with vegetables in a preheated oven and roast for 20-25 minutes, until tender and lightly browned, stirring halfway through cooking.

  6. Rest Pork at Room Temperature: While vegetables are roasting, remove marinated pork tenderloin from the refrigerator and let it sit at room temperature for 15-20 minutes.

  7. Place on a Lined Baking Sheet: Place pork tenderloin on a separate baking sheet lined with parchment paper or aluminum foil.

  8. Roast until Desired Temperature: Roast pork tenderloin in preheated oven for 20-25 minutes, until internal temperature reaches 145°F (63°C) for medium-rare or 160°F (71°C) for medium, using a meat thermometer to check doneness.

  9. Rest Pork: Once cooked, remove the pork tenderloin from the oven and let it rest for 5-10 minutes before slicing to allow juices to redistribute.

  10. Slice: Cut into thick slices.

  11. Serve: Serve hot, alongside roasted vegetables.
