Metric - US Standard

Instructions

  • Start by adding your chicken stock, garlic, soy sauce, honey, worcestershire sauce, onion granules and a pinch of salt and pepper to your crockpot. Stir to combine.
  • Place your pork tenderloin and rosemary into the crockpot and rotate with tongs to coat with the seasoned stock. Cook on high for 3 hours, or low for 6-7 hours. The internal cook temperature of the pork should read 145°F (62°C).
  • Set the pork aside and remove the rosemary. Increase the heat of your crockpot to high. Stir the cold butter cubes and cornflour slurry (1 tbsp cornflour + 2 tbsp cold water) into the pot. Heat until the butter is emulsified and the sauce has thickened nicely.
  • After resting for a minimum of 5-10 minutes, slice the pork tenderloin into rounds. Pour over the pan sauce and enjoy!

Notes

  • You can optionally sear your pork on one side for a bit of colour in a non-stick pan for 2 minutes over a high heat. If you do this, pull your pork tenderloin out at 135°F to prevent overcooking. 
  • I prefer to cook this on low for 6-7 hours but both lead to a succulent end-result. 
  • You can double the batch and freeze as a meal prep protein.
