Ingredients

Servings:

Units:

Main

  • 750 g Pork tenderloin, trimmed of excess fat

    Centre-cut or whole tenderloin works best

Seasoning

  • 5 g Sea salt

    For browning and seasoning

  • 3 g Freshly ground black pepper

Cooking

  • 15 ml Olive oil

    For browning the meat

  • 120 ml Chicken or vegetable stock

    For slow cooker liquid

Flavouring

  • 3 sprigs Fresh thyme or rosemary
    (optional)

    Add in final 30 minutes of cooking

  • 2 cloves Garlic cloves
    , crushed(optional)

Method

  1. 1

    Remove pork tenderloin from the refrigerator 10-15 minutes before cooking to allow it to come to room temperature. This ensures even cooking throughout.

    ~15 mins

    Tip: Room temperature meat cooks more evenly

  2. 2

    Pat the pork tenderloin dry with kitchen paper and season generously on all sides with sea salt and freshly ground black pepper.

    ~5 mins

    Tip: Dry surface helps achieve better browning

  3. 3

    Heat olive oil in a frying pan over medium-high heat until shimmering. Brown the pork tenderloin on all sides for 2-3 minutes per side, until golden brown. This step is important for flavour and should not be skipped.

    ~10 mins

    Tip: Browning develops a flavourful crust

  4. 4

    Transfer the browned pork tenderloin to your slow cooker. Pour the stock around the meat (not over it) and add crushed garlic if using.

    ~2 mins

    Tip: Keep liquid level moderate to prevent wateriness

  5. 5

    Cover and cook on High for 2.5 to 3 hours, or on Low for 4 hours. The pork is done when a meat thermometer inserted into the thickest part reads 63°C (145°F).

    ~2 hrs 30 mins

    Tip: Use meat thermometer for accuracy; do not overcook or meat will dry out

  6. 6

    In the final 30 minutes of cooking, add fresh thyme or rosemary sprigs if using.

    Optional step

    Tip: Fresh herbs maintain better flavour when added late

  7. 7

    Remove the pork tenderloin from the slow cooker and transfer to a warm plate. Cover loosely with foil and rest for 5-10 minutes before slicing.

    ~8 mins

    Tip: Resting allows juices to redistribute throughout the meat

  8. 8

    Slice the pork tenderloin against the grain into 2 cm (0.75 inch) thick medallions. Serve with the cooking liquid spooned over, or use it to make a simple pan sauce if desired.

    ~5 mins

    Tip: Slicing against the grain ensures tender, easy-to-eat pieces

Frequently Asked Questions

The best way is to use a meat thermometer. Pork is safely cooked when it reaches an internal temperature of 63°C (145°F). At this temperature, the meat will still be slightly pink in the centre and remain incredibly juicy. Remove it from the heat at this point and let it rest for 5-10 minutes before slicing. Overcooking beyond 68°C (155°F) will result in dryness
