Prepare the Marinade: In a bowl, combine honey, soy sauce, Dijon mustard, olive oil, minced garlic, and apple cider vinegar. Mix well until fully combined.

Marinate the Pork: Season the pork tenderloin with salt and pepper. Place the pork in a resealable plastic bag or a shallow dish. Pour the marinade over the pork, ensuring it’s fully coated. Seal the bag or cover the dish and refrigerate for at least 1 hour, preferably overnight to enhance flavor.

Preheat the Oven: Preheat your oven to 375°F (190°C).

Sear the Pork: Heat a skillet over medium-high heat. Remove the pork from the marinade (reserve the marinade) and sear it in the skillet for about 2-3 minutes on each side until browned.

Roast the Pork: Transfer the pork to a baking dish. Pour the reserved marinade over it. Roast in the preheated oven for about 20-25 minutes or until the internal temperature reaches 145°F (63°C).

Glaze the Pork: Every 5-10 minutes, baste the pork with the marinade in the dish.

Rest and Serve: Once cooked, remove from the oven and let it rest for about 5 minutes. Slice and garnish with chopped parsley before serving.
