Common Questions
What's The Difference Between Pork Loin And Pork Tenderloin?
You will often hear the words pork loin and pork tenderloin interchanged, but they are actually different cuts of meat. One difference that stands out is the thickness of the pork. A tenderloin is going to be a long and typically pretty narrow cut of meat while a pork loin is wide and much thicker.
Pork loin has a flavor and texture of a really big pork chop. Additionally, pork loins have more fat, are lighter in color, and is lighter in color.
Pork tenderloin is a super tender cut of meat, is leaner meat, and has a darker coloring. Tenderloins do tend to overcook rather quickly, so keep an eye on them. Otherwise, they won't be juicy but dry and will lose flavor too.
Can I make this in an air fryer?

Is Pork Tenderloin Healthy?
Yes, this pork tenderloin crockpot recipe is very healthy. Pork tenderloin is lean meat, so it's perfect if you are trying to watch what you eat. You will find that pork tenderloin is packed with protein, potassium, zinc, riboflavin, vitamin B6, phosphorus, and more. So, if you want to add some delicious protein to your diet, consider a pork tenderloin.
Can Pork Tenderloin Be Shredded?
Yes, you can shred pork tenderloin if you want to. Simply shred it with a couple of forks or place it in your Kitchenaide mixer with the paddle attachment. It will shred the pork super fast. This is another fantastic option to shred the pork then cover it in the gravy you made. So delicious!
What Is Glucomannan?
Glucomannan is a dietary fiber that can also be used as a way to thicken foods and gravies. I use glucomannan in my slow cooker pork tenderloin to make the gravy nice and thick. If you don't want to use glucomannan, that's no problem. You can simply replace it with your favorite thickener.
How Do You Store Slow Cooker Pork Tenderloin?
Always store the cooked pork tenderloin in an airtight container. You can wrap it with plastic wrap or tin foil then add it to an airtight container. It will last around 3-4 days in the fridge.
Storing the pork tenderloin in the freezer is another option that works well. Either slice the meat into individual servings or leave it as one big piece. Then wrap it with plastic wrap or aluminum foil then put in a freezer-safe bag or container. To defrost the meat, place it in the fridge the night before so it can thaw.
To reheat the slow cooker pork tenderloin, you can either microwave it for a minute or so or bake it. If you bake it, heat the oven to 350 degrees F. and heat for 10-15 minutes until it's hot all the way through.

Heather Dickson says
How would you double the gravy?
Taryn says
Add a cup of chicken broth to the cooking liquid before you add the thickener. You can add more thickener as desired.
Heather says
Thanks so much for the prompt reply! Trying this tomorrow
KellyAnn says
Just wonder how many slices are a serving size
Taryn says
It depends on how thick you cut it. This has 8 servings. So just divide the number of slices you get by 8. A serving is most likely 2-3.
S Jense says
I just put it in the crockpot. Hope it is a forgiving recipe because I misread the recipe. So busy looking for the lemon pepper I know I have that forgot the olive oil. Thankfully when I read thru the recipe again to see if my fresh ground recipe would do, I spotted the olive oil. This is Sunday dinner for tomorrow so will transfer it to the fridge in four hours and reheat tomorrow. Serving it with zucchini from my garden and riced cauliflower. My son will then raid the freezer for the non keto desserts he keeps there. It’s a win win.
Trisha says
Can you sear the meat first? I usually do.
Taryn says
Of course.
Iris says
Is their a substitute for Glucomannana? Can I use Almond flour or coconut flour?
Taryn says
You can use xanthan gum. I'm not sure either flour would work to thicken the gravy.
Kathy says
corn starch also or arrowroot powder $12. bucks for glucomannan supplements pills is ALOT if you are only using it as a thickening agent.
Taryn says
Those aren't really keto friendly. I buy one thing of glucomannan powder every 3-4 years. You only use a small amount in each recipe so if you divide by cost per recipe it is negligible.
Amanda says
This is the kind of recipe that makes my family excited to come home to. And actually gets me excited to cook! Thanks for the amazing recipe
Shadi Hasanzadenemati says

Jessica Formicola says
This pork tenderloin is perfection! Thanks for sharing the recipe
Jennifer says
I have a Boston butt I need to cook. Do I need to adjust this recipe in any way?
Taryn says
Pork butt takes longer to cook than tenderloin. 8-10 hours on low.
Leatha Burke says
I found this burned a bit in my slow cooker so I added water to the bottom.
Emily says
So it’s 4-6 pounds of tenderloin total?
Taryn says
No, 2-3 pounds. Sorry, if that wasn't clear. In general that's how much the standard pack with 2 pieces will weigh.
Susan says
Do you think this could be done in an instant pot?
Taryn says
Yes! I'm not sure on cooking time though. Maybe go with what is says in the instruction manual.
