Ingredients

For the Pork Tenderloin

• 1 teaspoon dried thyme or rosemary
• ½ teaspoon paprika
• Salt to taste
• Black pepper to taste

Optional Pan Juices Enhancement

Cooking Directions

Preheat the oven to 200°C (400°F). Pat the pork tenderloin dry with paper towels and remove any silver skin if present.
