1. Preheat your oven to 400°F (200°C). This high heat will help the glaze caramelize beautifully.
2. In a small bowl, whisk together the maple syrup, Dijon mustard, minced garlic, thyme, salt, pepper, and optional red pepper flakes. This glaze is the heart of the dish—sweet, tangy, and just a little spicy.
3. Pat the pork tenderloin dry with paper towels. This step is key for getting a nice sear.
4. Heat 1 tablespoon of olive oil in a large oven-safe skillet over medium-high heat. When the oil shimmers, add the pork tenderloin and sear it on all sides until golden brown, about 2-3 minutes per side. This locks in the juices and adds flavor.
5. Remove the skillet from heat and brush the pork generously with half of the maple Dijon glaze.
6. Transfer the skillet to the oven and roast for 15-20 minutes, or until the internal temperature reaches 145°F (63°C). I always use a meat thermometer here—nothing beats a perfectly cooked tenderloin.
7. About halfway through roasting, brush the pork with the remaining glaze for an extra glossy, flavorful finish.
8. Once done, remove the pork from the oven and let it rest for 5-10 minutes. This resting time is essential—it lets the juices redistribute so every bite is juicy and tender.
9. Slice the tenderloin into medallions and serve immediately, spooning any pan juices over the top for extra flavor.

One of my favorite things about this recipe is how forgiving it is. I’ve made it with busy weeknight chaos swirling around me, and it still turns out beautifully. The glaze is a simple mix, but the way it clings and caramelizes on the pork feels like a little kitchen magic every time.
