Preheat your oven to 400°F. Pat the pork tenderloin dry with paper towels and season it generously with salt and pepper.
In a small bowl, whisk together the maple syrup, Dijon mustard, minced garlic, apple cider vinegar, soy sauce, and thyme leaves. This is where the magic happens, as each ingredient melds together to create a glaze that’s both vibrant and comforting.
Heat the olive oil in a large oven-safe skillet over medium-high heat. Once the oil shimmers, add the pork tenderloin and sear it on all sides until golden brown, about 2-3 minutes per side. This step locks in the juices, ensuring a tender bite.
Pour the maple mustard glaze over the seared pork, using a spoon to coat the tenderloin evenly. Transfer the skillet to the preheated oven.
Roast the pork for 15-20 minutes or until an instant-read thermometer inserted into the thickest part reads 145°F. Basting the pork with the glaze halfway through cooking will enhance the flavors.
Remove the skillet from the oven and let the pork rest for at least 5 minutes before slicing. This rest period is crucial for allowing the juices to redistribute, resulting in a moist and flavorful dish.
