Take the pork tenderloin out of the fridge. Let it sit for 10 minutes. This helps even cooking. Pat it dry with paper towels. Dry meat gives a better sear. Season with salt and black pepper on all sides.

In a small bowl, mix garlic, rosemary, thyme, lemon zest, honey, and mustard. Stir well until combined. This mixture adds rich flavor. It smells fresh and tasty. Keep it ready for later use.

Place a large frying pan on medium heat. Add olive oil and let it warm up. The oil should be hot but not smoking. A hot pan helps create a golden crust.

Place the pork in the hot pan. Sear each side for 2–3 minutes. Turn it using tongs. You want a golden brown color. This locks in juices and adds deep flavor.

Add butter to the pan. Let it melt slowly. Spoon the butter over the pork. This step adds richness. It also keeps the meat moist and soft.

Now spread the garlic and herb mixture over the pork. Coat it evenly. The smell at this stage is amazing. Make sure every side gets covered.

Transfer the pork to an oven-safe dish. Bake at 180°C for 15–18 minutes. Cooking time depends on thickness. The inside should be slightly pink for best results.

Remove the pork from the oven. Let it rest for 5–10 minutes. Do not skip this step. Resting keeps the juices inside. Slice after resting for perfect texture.

Slice the pork into thick pieces. Arrange on a plate. Spoon pan juices on top. Serve warm and enjoy every bite.
