Health Benefits of Stuffed Pork Tenderloin

This recipe offers several health benefits thanks to its nutritious ingredients:

Lean Protein

Pork tenderloin is one of the leanest cuts of pork. It’s rich in high-quality protein, which is essential for muscle repair, tissue health, and satisfied hunger. Compared to fattier cuts, it has less saturated fat, making it a heart-healthier choice.

Spinach: A Super Green

Spinach is a nutrient-dense leafy green loaded with iron, magnesium, and vitamins A and C. It supports healthy skin, boosts immunity, and strengthens bones. Its high fiber content also helps digestion.

Quinoa: A Complete Grain

Quinoa is a gluten-free whole grain that’s high in protein and contains all nine essential amino acids. It’s also a good source of fiber, minerals like magnesium and iron, and plant-based antioxidants that promote overall health.

Precautions

If you’re watching your sodium intake, be careful with seasonings and broths used during cooking. Also, make sure to cook pork tenderloin to a safe internal temperature of 145°F (63°C) and allow it to rest before slicing to retain juices and ensure food safety.

Stuffed Pork Tenderloin with Spinach and Quinoa Recipe

Ingredients

  • 1 pork tenderloin (about 1.5 lbs)
  • 1/2 cup cooked quinoa
  • 2 cups fresh spinach, chopped
  • 2 cloves garlic, minced
  • 2 tablespoons olive oil
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 tablespoon Dijon mustard (optional)
  • Cooking twine or toothpicks for securing

Instructions

  1. Preheat oven: Set your oven to 400°F (200°C).
  2. Prepare stuffing: In a skillet, heat 1 tablespoon of olive oil over medium heat. Add garlic and spinach and sauté for 2–3 minutes until wilted. Mix in cooked quinoa, rosemary, thyme, salt, and pepper. Set aside.
  3. Butterfly the pork: Carefully slice the pork tenderloin lengthwise down the center, being careful not to cut all the way through. Open the meat like a book and flatten it with a meat mallet if needed.
  4. Stuff and roll: Spoon the quinoa and spinach mixture evenly down the center of the pork. Roll the tenderloin and secure with twine or toothpicks.
  5. Season and sear: Rub the outside of the tenderloin with remaining olive oil and optional Dijon mustard. Season with extra herbs, salt, and pepper. Sear the tenderloin in an oven-proof skillet over medium-high heat for 2–3 minutes on each side for a golden crust.
  6. Roast in oven: Transfer the skillet to the preheated oven and roast for 20–25 minutes or until the internal temperature reaches 145°F (63°C).
  7. Rest and slice: Let the pork rest for 5 minutes before slicing into rounds. Serve warm.
