1. Preheat your oven to 375°F (190°C). This ensures your pork will cook evenly and develop a beautiful crust.
2. In a small bowl, whisk together the maple syrup, Dijon mustard, olive oil, minced garlic, thyme, salt, and pepper. If you’re using apple cider vinegar for an extra tang, add it in now.
3. Pat the pork tenderloin dry with paper towels. This step helps the marinade adhere better and promotes browning.
4. Place the tenderloin in a shallow baking dish and pour the maple mustard mixture over it, making sure it’s well coated. Let it marinate for at least 15 minutes to soak up all those delicious flavors.
5. Transfer the baking dish to the oven and roast for 25-30 minutes, or until the internal temperature reaches 145°F (63°C). I like to use a meat thermometer to ensure perfect doneness without overcooking.
6. Once cooked, remove the tenderloin from the oven and let it rest for about 5 minutes before slicing. This helps retain the juices, keeping your pork tender and succulent.

Cooking with pork can feel intimidating, but trust me, it’s all about timing and confidence. Remember, cooking is as much about the senses as it is about following instructions, something I learned from my grandmother as a child.
