Recipe Notes

Other tips to make this the Best Slow Cooker Pork Loin You'll Have:

  1. Want a deeper flavor? Marinate your pork loin for 24 hours beforehand. This heightens the flavor. Just remember that you'll sear it for a bit less than the 5 minutes we did because of all the sugar that will caramelize in the pan. Once you get a nice crusty sear on your pork loin, call it good.  
  2. Not a fan of soy sauce? Try coconut aminos. Trader Joes' sells it by the bottle, it's delicious and a nice variation from soy sauce.
  3. Want a nice gravy like sauce to go with your slow cooker pork loin? Take the leftover sauce from the slow cooker, add it to a shallow pan along with a 1 to 2 ratio (1 part cornstarch, 2 parts water) cornstarch slurry.  It will thicken up and make for a delicious sauce to pour over the pork loin!
  4. Squeeze some fresh lime on your pork; it adds a nice zesty flavor.
