Pork Tenderloin with Dijon and Tarragon Sauce

Lean, quick-cooking pork tenderloin works especially well with a French-style pan sauce, where browned meat juices are folded into a reduction of shallot, dry white wine and Dijon mustard. Double cream gives the sauce a smooth, rounded texture, while fresh tarragon adds its distinctive aniseed note without overwhelming the pork. The result is a simple dinner with enough polish for entertaining: sliced medallions of tender pork, served straight away with a tangy, aromatic cream sauce that feels rich but not heavy. It pairs naturally with potatoes, rice or green vegetables.

Why this recipe works

  • Built-in flavour base: Searing the pork first leaves browned bits in the pan, which are lifted into the wine, mustard and cream sauce.
  • Rich but balanced: Dijon mustard and dry white wine cut through the double cream, keeping the sauce lively rather than heavy.
  • Fast cooking: Pork tenderloin cooks quickly on the hob, making this a full-flavoured dinner in about 35 minutes.

Texture tips

  • Rest before slicing: Let the pork rest for 5 minutes so the juices settle before it is cut into slices.
  • Keep the sauce gentle: Once the cream is added, use a low simmer rather than a hard boil to help the sauce stay smooth.

Ingredient notes

  • Use Dijon for sharpness: Dijon mustard gives the sauce its clean tang and helps balance the richness of the cream.
  • Fresh tarragon works best: Fresh tarragon adds a distinctive anise-like aroma; parsley can be used for a milder, greener finish.

Common mistakes

  • Avoid dry pork: Pork tenderloin is lean, so cook it just until done; a thermometer should read 63°C (145°F) in the thickest part before resting.
  • Do not rush the reduction: Let the wine reduce before adding the mustard and cream, or the sauce may taste thin and sharp.

Ingredient swaps

  • Alcohol-free sauce: Use chicken stock instead of dry white wine for a softer, alcohol-free pan sauce.
  • Change the herb: Swap tarragon for fresh parsley if you prefer a less aromatic, more neutral herb flavour.

  1. Pat the pork dry, then season all over with the salt and pepper. Finely chop the shallot and pick the tarragon leaves, then roughly chop the leaves.
  2. Heat a large frying pan over medium-high heat and add the butter. When foaming, add the pork and sear for 2–3 minutes per side until well browned all over.
  3. Reduce the heat to medium and continue cooking, turning occasionally, for 6–10 minutes until the pork is just cooked through and the juices run clear. Transfer to a board and rest for 5 minutes.
  4. Add the shallot to the same pan and cook for 1–2 minutes until softened. Pour in the wine and simmer, scraping up any browned bits, for 3–5 minutes until reduced by about half.
  5. Lower the heat and whisk in the mustard, then stir in the double cream. Simmer gently for 2–3 minutes until smooth and lightly thickened, then stir in most of the tarragon and taste for seasoning.
  6. Slice the pork and spoon the sauce over the top. Finish with the remaining tarragon and serve straight away.

Recipe notes

Tips

  • Keep the sauce at a gentle simmer after adding the double cream so it stays smooth and does not split.
  • If you have a thermometer, aim for 63°C (145°F) in the thickest part of the pork, then rest it for 5 minutes before slicing.

Substitutions

  • Replace Fresh tarragon with Fresh parsley for a milder, greener finish.
  • Replace Dry White Wine with Chicken stock for an alcohol-free sauce.

Storage

  • Refrigerate up to 2 days
  • Cool, then refrigerate the pork and sauce in an airtight container. Reheat gently in a frying pan over low heat with a splash of water, stirring often, until piping hot; avoid boiling the sauce.
