FAQS & Tips

What is a pork loin roast?

Pork loin is a large, lean cut of meat taken from the back of the pig. It is known for being tender and mild in flavor.  It’s a versatile cut that pairs well with a variety of seasonings.

Can you use a bone-in pork loin?

Yes, you can use a bone-in pork loin for this recipe. If you do, keep in mind that bone-in pork loins longer to cook. Also, be sure your slow cooker is large enough to fit it. Remove the bone after cooking, then slice and serve.

Is a pork loin the same as a pork tenderloin?

No. A pork loin roast is not the same thing as a pork tenderloin. Pork tenderloin is long and thin. A pork loin roast is wider and thicker. Since pork loin is larger, it requires longer cooking time. A tenderloin cooks much faster.

How do you store leftovers?

Store leftover crockpot pork loin in the refrigerator for up to 4 days. 

What size slow cooker should you use?

I used a 6-quart slow cooker or Instant Pot.
