Simple Pork Tenderloin

Pork tenderloin is a simple dish, and all you have to do is add some basic ingredients and let the pork marinate overnight.
Then, the next day turn on the Crock Pot, add a couple more simple ingredients and let it cook all day. It’s such an easy meal.
Getting it started only takes a few minutes of prep, and after cooking the next day, you get the most tender pork.

Step-By-Step Instructions
Making The Rub

Grab a small bowl and add the brown sugar.

Next, add the smoked paprika.
If you only have regular paprika, that will work, too.

Add the garlic salt, cumin, onion powder, and dry mustard.

Next, sprinkle the chili powder on top.

Finally, add the salt and black pepper.

Mix the ingredients.

Add the pork tenderloin to a casserole dish.
You don’t need to spray it because you won’t be using the dish for cooking. You will only be using the dish to allow the pork to marinate in the fridge.

Sprinkle the rub all over the pork and give it all a good rub in.

Make sure you get the rub on all sides of the pork. Cover the dish with plastic wrap and place it in the refrigerator for about 24 hours.
If you need to cook it sooner, that is fine. It’s not imperative that is sits for 24 hours with the rub, but the seasonings will penetrate the meat better the longer they sit.
Cooking In The Slow Cooker

Spray the slow cooker with nonstick cooking spray and place the pork in the bottom.

Pour one can of Dr. Pepper over the pork.
Place the lid on top and cook on low heat for seven hours.

After seven hours, remove the slow cooker lid and shred the pork.

Add the cornstarch and water to a small bowl and mix well.
Don’t add the cornstarch directly into the liquid in the Crock Pot, or it will clump up.
You want it to go into the pot in liquid form. I didn’t use a lot, so it wasn’t that thick of gravy. If you want it thicker, add some more cornstarch.

Pour the cornstarch and water into the slow cooker and mix. Replace the lid and cook on low for another 30 minutes.

Once you get to the end of the cooking time, it’s time to eat! You can pour a little bit of the gravy on top, and you’ve got a great meal!
I like to serve pork tenderloin over mashed potatoes with some vegetables on the side.
