Pork Tenderloin with Prunes and Armagnac
Why this recipe works
- Layered sauce: Browning the pork first leaves savoury pan juices that are lifted by Armagnac, stock, shallots and thyme.
- Sweetness kept in check: Prunes add fruitiness and body, while Dijon mustard and chicken stock keep the sauce from tasting too sweet.
- Glossy finish: Whisking in mustard and finishing with butter off the heat gives the pan sauce a smooth, shiny texture.

Timing notes
- Rest before slicing: Let the pork rest briefly after simmering so the juices settle before it is sliced.
- Serve promptly: The sauce is at its best hot from the pan, while it is still glossy and loose enough to coat the pork.
Ingredient notes
- Armagnac character: Armagnac brings warm, rounded fruit and oak notes that suit prunes particularly well; brandy is the closest everyday substitute.
- Choose soft prunes: Use plump, tender prunes so they soften into the sauce rather than staying firm and chewy.
- Mustard balance: Dijon sharpens the sauce at the end, balancing the sweetness of the fruit and the richness of the butter.
Common mistakes
- Avoid dry pork: Once the stock and prunes are added, keep the simmer gentle; hard boiling can overcook the tenderloin before the sauce reduces.
- Control the reduction: If the sauce tightens too quickly, lower the heat and loosen it with a little more stock before finishing.
- Add mustard late: Whisk the Dijon in near the end so it keeps its brightness and helps emulsify the sauce.
Serving ideas
- Serve with something absorbent: Mashed potatoes, buttered noodles or a simple root vegetable purée work well with the prune and Armagnac sauce.
- Add a green side: Steamed green beans, wilted spinach or a crisp bitter-leaf salad help balance the richness.

Ingredients
Instructions
- Pat the pork dry, then season all over with the salt and pepper. Peel and finely chop the shallots.
- Heat the olive oil and half the butter in a large frying pan over medium-high heat. Sear the pork for 6 to 8 minutes, turning with tongs, until well browned all over.
- Reduce the heat to medium and add the shallots and thyme sprigs to the pan. Cook for 2 to 3 minutes, stirring, until the shallots soften and smell sweet.
- Pour in the Armagnac and let it bubble for about 1 minute, scraping up any browned bits from the pan. Add the chicken stock and prunes, then bring to a gentle simmer.
- Cover loosely and simmer gently for 10 to 12 minutes, turning the pork once, until it is just cooked through and the sauce has started to reduce. The pork should feel firm but still springy when pressed.
- Transfer the pork to a board and rest for 5 minutes. Keep the pan on a low simmer while it rests.
- Whisk the Dijon mustard into the sauce, then simmer for 2 to 4 minutes until glossy and lightly thickened. Off the heat, swirl in the remaining butter to finish.
- Slice the pork and return any resting juices to the pan. Spoon the prunes and Armagnac sauce over the pork to serve.
Recipe notes
Tips
- Keep the simmer gentle once the stock goes in; a hard boil can make the pork dry before the sauce turns glossy.
- If the sauce reduces too quickly, add a small splash of chicken stock and continue simmering until it coats the back of a spoon.
- Alcohol note: if serving to children or anyone avoiding alcohol, simmer the Armagnac for a full 2 minutes before adding the stock to cook off more of the alcohol.
Substitutions
- Replace Armagnac with brandy for a similar warmth and aroma.
- Replace Dijon mustard with whole-grain mustard for a milder heat and a coarser texture.
Storage
- Refrigerate up to 3 days
- Cool, then refrigerate in a sealed container. Reheat gently in a frying pan over low heat with a splash of chicken stock until piping hot, taking care not to boil hard.
