It’s called pork tenderloin with apple – onion marmalade but really, it’s more of a conglomeration of apples, caramelized balsamic onions and prunes. This is a wonderful dish for entertaining because beyond tasting out of this world good, the marmalade can be made well ahead of time and just reheated before serving.
This is an often asked for meal at my house and most people have no clue there are prunes in there. It’s all cooked for so long that the prunes disintegrate and all you get is the smoothness they impart along with a bit of sweetness.

Instructions
- In a saute pan over medium heat, warm the 3 tablespoons olive oil.
- Add the onion and saute until golden brown, about 5 minutes.
- Add the balsamic vinegar, sherry vinegar, water and salt and pepper to taste and cook until the liquid has evaporated and the onions are very soft, about 45 minutes. Set aside.
- Preheat an oven to 450 degrees F.
- Rub salt and pepper to taste on all sides of the tenderloins. Place them in a roasting pan.
- Pour the ¼ cup (2 fl oz/60 ml) olive oil over the top. Place 1 thyme sprig on each tenderloin.
- Place the pan in the oven and roast the pork for 10 minutes.
- Turn the pork over and roast until firm and pale pink in the center when cut with a knife, about 10 minutes longer.
- While the pork is cooking, in a large saute pan over medium heat, melt the butter.
- Add the apple and prunes and saute until slightly soft and caramelized, 3-5 minutes.
- Add the onion marmalade mixture to the pan and continue to saute until the flavors have blended, 2-3 minutes longer.
- Add the stock to the pan and bring to a boil. Immediately remove from the heat and cover to keep warm.
- When the pork is done, transfer it to a cutting board, cover with aluminum foil and let rest for 5 minutes. Then, using a sharp knife, cut the pork tenderloins into slices ½-inch (12 mm) thick. Arrange the pork slices on a warmed serving platter.
- Spoon the warm marmalade mixture over the pork. Sprinkle with the parsley and serve immediately.
