Can I use pork loin instead of tenderloin?
No. The difference between the two is that pork tenderloin is long, narrow and boneless cut of meat where as a pork loin roast is much bigger and wider and can be either a bone in or boneless cut of meat.
They both come from different parts of the animal and are not a substitute for one another.
While both are lean cuts of meat, the tenderloin is has more flavor and is much more tender than the loin. It’s the filet mignon of pork. It tends to be a bit more expensive but to me it’s worth it.
Recipe ingredients I used.
This is a very easy recipe that uses simple ingredients. I used a pork tenderloin roast and the following seasoning blend – onion powder, garlic powder, salt, black pepper, paprika and thyme.
I added just a fresh onion and a carrot or two for the vegetables but you could use any roast vegetables you want to make it more of a complete meal. Most people would add cubed potatoes but I was trying to keep the carbs down.
However the yellow onion is important because it will cook and caramelize and go great with the meat.
How to make this simple slow cooker pork tenderloin recipe.
Step 1: Spray the slow cooker with cooking spray and then hop the onions into large pieces or thick slices. Lay on the bottom of the slow cooker.
Step 2: Mix the seasonings (salt, black pepper, garlic powder, onion powder, thyme and paprika). Rub all over the pork roast. Then set it in the crockpot on top of the onions. Add the chopped carrots or whatever veggies you want on top.
The cooked onion is important to give the meat additional flavor but the other veggies are not. Make sure the vegetables are in big pieces so they don’t get too mushy.
Note: I don’t add any liquid like chicken broth for example because I didn’t want the meat or the veggies to get soggy. Some people add a bit of liquid so the meat won’t dry out but I found that only happens if you cook it too long.
Step 3: Place the lid on the slow cooker and cook on high 3 and half hours or until the roast is done. The internal temperature should be 145 degrees F. Note cooking time may vary depending on the size of your roast.
Step 4: Place the roast on a platter and cover with a piece of foil. Let rest for 10 minutes then slice and spoon the veggies around the meat. If you have any juices in the crockpot, spoon them over the meat slices.

5 stars!
Delicious! Usually make pork tenderloin with root beer and barbecue sauce… a lot to sugar. Was a little worried how this was going to turn out but it was fantastic! The husband even asked if it was made with root beer because there’s definitely a bit of sweetness. Added potatoes, carrots and parsnips and let those cook a little longer while the tenderloin was covered. Will definitely make again. Thank you!

Can you put some cabbage on top of the pork and carrots ?
Denise
Hi Diane, I don’t see why not. You can use any veggies you want but realize some will get very mushy but cabbage probably won’t. Hope that helps and let me know how it went!
