Pork Tenderloin with Dijon Mustard Sauce
Why this recipe works
- Pan-built flavour: Searing the pork first leaves savoury browned bits in the pan, which become the base of the wine and mustard sauce.
- Smooth, tangy sauce: Crème fraîche softens the sharpness of Dijon mustard and gives the sauce a rounded, lightly creamy finish.
- Fast enough for weeknights: The pork and sauce are cooked in the same pan, keeping the method efficient without sacrificing depth of flavour.

Timing notes
- Rest before slicing: Let the pork rest briefly after cooking so the juices settle and the slices stay tender.
- Serve the sauce gently warm: Once the crème fraîche is added, keep the sauce over low heat and serve soon after it thickens.
Common mistakes
- Avoid firm, dry pork: Pork tenderloin is lean, so stop cooking as soon as it feels springy rather than hard.
- Do not boil the sauce: A hard boil after adding crème fraîche can make the sauce split; gentle heat keeps it smooth.
Ingredient notes
- Use a proper Dijon mustard: Dijon gives the sauce its clean sharpness and savoury depth; a very sweet mustard will change the balance.
- Fresh herbs suit the quick sauce: Fresh thyme perfumes the pan without needing a long simmer, while tarragon gives a more classic bistro-style note.
Serving ideas
- Serve with potatoes or greens: Buttery potatoes, mash, green beans or sautéed greens work well with the creamy mustard sauce.
- Pair with a dry white wine: A crisp dry white echoes the wine in the sauce and balances the richness of the crème fraîche.

Ingredients
Instructions
- Pat the pork dry, then season all over with the fine sea salt and black pepper. Peel and finely chop the shallot, and strip a few thyme leaves from the sprigs (keep the sprigs for the pan).
- Heat a frying pan over medium-high heat and add the unsalted butter. When it foams, add the pork and thyme sprigs, then sear for 2 to 3 minutes per side until well browned all over.
- Turn the heat down to medium and continue cooking, turning occasionally, for 6 to 10 minutes until the pork is just cooked through and the juices run clear. Transfer to a board and rest for 5 minutes.
- Pour off any excess fat, leaving a thin coating in the pan, then add the shallot with the thyme leaves. Cook for 1 to 2 minutes until softened, then pour in the dry white wine and simmer for 2 to 3 minutes, scraping up any browned bits, until reduced by about half.
- Lower the heat and stir in the Dijon mustard and crème fraiche until smooth and lightly thickened, about 1 to 2 minutes; do not let it boil. Slice the pork and spoon the sauce over to serve.
Recipe notes
Tips
- For the juiciest result, stop cooking the pork as soon as it feels springy but not firm, then let it rest so the juices settle before slicing.
- Keep the sauce at a gentle heat once the crème fraiche goes in; a hard boil can cause it to split.
- If serving anyone who should avoid alcohol, simmer the wine thoroughly so the sauce reduces well and the flavour mellows.
Substitutions
- Replace Crème fraiche with double cream for a richer, silkier sauce.
- Replace Fresh thyme with fresh tarragon for a more aniseed, classic bistro-style note.
- Replace Dry White Wine with dry sherry for a deeper, slightly nutty sauce.
Storage
- Refrigerate up to 2 days
- Cool leftovers quickly, then refrigerate in a sealed container. Reheat the pork and sauce gently in a frying pan over low heat with a splash of water, stirring often, until piping hot; avoid boiling the sauce.
