Begin by preheating your oven to 375°F (190°C) to ensure it's at the right temperature when you're ready to cook.
Take the turkey tenderloins and pat them dry with paper towels; this step is crucial for achieving a nice sear. Season both sides generously with salt and freshly ground black pepper.
In an oven-safe skillet, melt 2 tablespoons of unsalted butter over medium heat. Allow the butter to foam and become fragrant, indicating it's ready for the next step.
Once the butter is melted, add the minced garlic to the skillet. Sauté the garlic for about 1 minute, stirring frequently, until it becomes fragrant and just begins to turn golden; be careful not to let it burn.
Carefully add the seasoned turkey tenderloins to the skillet. Sear them for approximately 2-3 minutes on each side, until they develop a beautiful golden-brown crust.
After searing, evenly sprinkle the dried thyme, dried rosemary, and lemon zest over the tenderloins. Drizzle the fresh lemon juice on top for an added zing of flavor.
Next, add the remaining 2 tablespoons of butter to the skillet, letting it melt and mingle with the aromatics.
Now, transfer the skillet to the preheated oven. Bake the turkey for 20-25 minutes, or until it reaches an internal temperature of 165°F (75°C) when checked with a meat thermometer.
Once cooked, carefully remove the skillet from the oven. Allow the tenderloins to rest for about 5 minutes; this helps the juices redistribute for better flavor.
Slice the tenderloins against the grain into medallions and drizzle the savory pan juices over the top for moistness and added flavor.
Finally, garnish with freshly chopped parsley to add a touch of color and freshness before serving.
