Preheat the oven to 400 degrees. Clean and pat dry the pork loin, removing any fat and silver skin. Cut the loin into 4 equal size portions.
Mix the pork seasonings in a small bowl. Lightly coat each pork portion with 2-3 Tbsp of oil, followed by the seasoning, ensuring all sides are covered.
In a large pan over medium heat, add 1-2 Tbsp of oil. Sear each loin for 2-3 minutes per side or until golden-brown crust forms. Transfer to a baking dish lined with a wire rack. Reduce heat to low.
Place the pork loin in the preheated oven for 15-20 minutes, checking with a meat thermometer at the halfway point. For medium-rare, aim for 145 degrees; for more well-done, aim for 155 degrees. Thinner pieces may cook faster.
While the pork cooks, prepare the sauce. In the same pan, turn the heat to low and add ¼ cup water or chicken stock to deglaze. Scrape the brown bits from the pan, then add the remaining sauce ingredients. Simmer, stirring often.
Once the pork is done, remove it from the oven. Switch to low broil. Brush sauce onto the pork and return to the oven for 30 seconds to 1 minute until the top is bubbly.
Transfer the pork to a cutting board, brush with another coating of sauce, cover lightly with foil, and let it rest for 5 minutes.
After resting, cut the pork and serve with extra sauce and your favorite sides. Consider pairing it with Air-Fried Parmesan Brussels Sprouts for a delicious meal.
