Method
- 1
Pat the pork tenderloin dry with kitchen paper and season generously on all sides with salt, black pepper, and cayenne pepper.
~5 minsTip: Drying the meat helps achieve a good sear
- 2
Heat the olive oil in a large frying pan over a medium-high heat until just beginning to smoke. Sear the pork tenderloin on all sides until golden brown, approximately 2–3 minutes per side.
~12 minsTip: This develops flavour and colour; do not skip this step
- 3
Place the seared pork tenderloin into your slow cooker. Pour the stock around (not over) the meat.
~3 mins - 4
Cover and cook on Low for 6 hours or High for 3 hours, until the pork reaches an internal temperature of 63°C (145°F) and is tender.
~6 hrsTip: Use a meat thermometer for accuracy
- 5
In a small bowl, whisk together the Dijon mustard and double cream until smooth and well combined.
~3 mins - 6
With approximately 20 minutes of cooking time remaining, carefully remove the pork from the slow cooker and set aside on a warm plate. Whisk the mustard and cream mixture into the cooking liquid in the slow cooker.
~5 minsTip: Stir well to create a smooth, silky sauce
- 7
Return the pork to the slow cooker and cook for the remaining 20 minutes, allowing the sauce to warm through without boiling.
~20 minsTip: Do not allow to boil, as this may cause the cream to separate
- 8
Remove the pork tenderloin from the slow cooker and place on a clean chopping board. Rest for 5 minutes before slicing.
~5 minsTip: Resting ensures the meat remains juicy
- 9
Slice the rested pork and arrange on a serving platter. Spoon the spicy mustard cream sauce over the slices and garnish with fresh parsley if desired. Serve immediately.

Frequently Asked Questions
Pork tenderloin is ideal because it's lean and cooks evenly in the slow cooker. If substituting, choose a similarly sized cut such as a pork loin, but note that cooking times may vary. Avoid heavily marbled cuts as they may become too soft after extended slow cooking
