Preheat the oven
Set your oven to 375°F (190°C). This gives enough heat to caramelize the crust while keeping the inside juicy.
Prepare the mustard rub
In a bowl, combine Dijon mustard, ¼ cup brown sugar, olive oil, thyme, garlic, salt, and pepper. Rub generously all over the pork loin.
Roast the pork
Place the loin in a roasting pan and bake for 60–75 minutes (20 minutes per pound) until it reaches an internal temp of 145°F (63°C). Tent with foil and let it rest 10 minutes before slicing.
Make the cranberry apple topping
While the pork roasts, heat butter in a saucepan over medium heat. Add cranberries, diced apple, ¼ cup brown sugar, cinnamon, and nutmeg. Cook 10 minutes, stirring until the fruit is soft and jammy.
Prepare the apple cider glaze
In a separate saucepan, simmer apple cider, Dijon mustard, 2 tbsp brown sugar, and balsamic vinegar for 10 minutes until thickened.
Assemble & serve
Slice the roast and spoon the cranberry topping over it. Drizzle with glaze and garnish with thyme or parsley.
