  • 180 ml Chicken or vegetable stock

    Adjust to taste for desired heat level

  • 3 ml Salt
  • 1 ml Black pepper, freshly ground

  • 15 ml Olive oil

  • 15 g Fresh parsley

Method

  1. 1

    Pat the pork tenderloin dry with kitchen paper and season generously on all sides with salt, black pepper, and cayenne pepper.

    ~5 mins

    Tip: Drying the meat helps achieve a good sear

  2. 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 mins

    Tip: This develops flavour and colour; do not skip this step

  3. 3

    Place the seared pork tenderloin into your slow cooker. Pour the stock around (not over) the meat.

    ~3 mins
  4. 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 hrs

    Tip: Use a meat thermometer for accuracy

  5. 5

    In a small bowl, whisk together the Dijon mustard and double cream until smooth and well combined.

    ~3 mins
  6. 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 mins

    Tip: Stir well to create a smooth, silky sauce

  7. 7

    Return the pork to the slow cooker and cook for the remaining 20 minutes, allowing the sauce to warm through without boiling.

    ~20 mins

    Tip: Do not allow to boil, as this may cause the cream to separate

  8. 8

    Remove the pork tenderloin from the slow cooker and place on a clean chopping board. Rest for 5 minutes before slicing.

    ~5 mins

    Tip: Resting ensures the meat remains juicy

  9. 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.

    ~5 mins

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
