A little Cajun seasoning and a few crushed red pepper flakes add just a little zip to this recipe. In addition to garlic, there’s also thyme added for flavor. Rosemary could be used instead.

There’s no need to add any liquid to the slow cooker. The butter will melt and coat the pork and the pork will release its own juices.

Recipe Tips

It is important to note that this recipe is made with a pork loin, not pork tenderloin. They are two very different cuts of meat. Pork Loin can also be labeled Center Cut Pork Roast or Center Cut Rib Roast.

Should be done in 5 to 6 hours, but depending on your crock pot and the size of your pork loin, it may take up to 7 hours on LOW. To be sure it is done, use an instant read thermometer and insert it in the thickest portion. It should read 145F.

Let the roast rest for at least 10 minutes before slicing.

It’s fine to leave the pork in the crock pot on warm after it is done cooking if it is not yet dinnertime.

Leftovers can be stored in an airtight container in the refrigerator for 3 to 4 days.

  1. Can’t tell you how many times I’ve made this recipe now – at least every other month. It’s really simple and tasty!

  2. I have made this recipe probably 3-4 times now….it’s so easy and so stupidly good. Highly recommended! I do Keto so I just use a little xanthan gum to thicken rather than cornstarch.

  3. I see you’re adding no liquids. Is the roast and veggies producing enough moisture not to dry it out?

      Joe, I just did the roast alone, no veggies. There is plenty of moisture with the meat juices and butter. And HOLY COW! Is this good. Oh my! Yessiree, doing this one again for sure! I think part of the moisture situation is that it is slow cooked and covered. The condensation helps.
