First, you will need to thaw the meat. To do this, I recommend putting the frozen pork loin in the fridge overnight, or for a day so that it can thaw completely.
When you are ready to start cooking it, begin by making the delicious dry rub. In a small mixing bowl, combine brown sugar, garlic powder, and soy sauce. Wisk to combine.
Remove the pork loin from the packaging, and rub the entire outside of the pork with olive oil. Then take your rub, and sprinkle it so that the outside of the pork is covered in it. Place it in the crockpot and add chicken broth, then cover with a lid.
You can use the low heat setting or high heat setting on your crockpot. Your cooking temperature will determine how fast the pork loin cooks.
To cook your pork loin on low, the cooking time will be approximately 7-8 hours, or on high, for an approximate cooking time of 4-5 hours. Please note that the exact cook time may vary slightly depending on how big your pork loin is, and your specific crockpot.
To tell when your pork loin is done cooking, you want to check the internal temperature of your roast with a meat thermometer. You will want the instant-read thermometer to read 145 degrees F, and the pork loin should be fork tender, meaning when you insert a fork, it should be nice and tender.
When your pork loin is fully cooked, remove it from the crockpot and allow it to rest for a few minutes on a cutting board. Then slice the pork roast and serve. Enjoy!
