Best Slow Cooker Pork Tenderloin Recipe

This slow cooker pork tenderloin is one of the most delicious yet easy dishes you can make. You put the ingredients in the pot, turn it on, and let it do the work for you.

You can also use an Instant Pot to cook a pork tenderloin. I put the basic directions below. It’s faster, but I still prefer cooking a tenderloin in my slow cooker because a slow cooked tenderloin maintains some of its firmness for slicing.

Pork is one of our favorite foods because it’s so versatile. You can cook it on the stovetop, in the oven, in your slow cooker, in an Instant Pot, in an air fryer, and even in a Dutch oven. Plus, you can use pork in most chicken recipes and get excellent results.

Easy Family Dinner Main Dish

When you use a Crock Pot, it basically cooks itself without worry about what temperature to cook a pork tenderloin. That’s one of the main things I enjoy about my slow cooker, which is why I use it a lot.

You can either put everything together first thing in the morning or make a bunch of freezer meals to put in the slow cooker later.

Slow cooker aside, a pork tenderloin also makes wonderful leftovers. I’ll explain how to reheat leftover pork tenderloin below.

There are so many recipes you can make with it the next day, like shredded pork sandwiches and casseroles with either potatoes or rice.

Regardless of how you prepare any crockpot dinner, the flavors come together in a blend of deliciousness.

Also, there’s nothing better than coming home to the aroma of dinner at the end of a long day.

It’s nice that all you have to do now is get the sides ready since the meat is done.

Another option is to add vegetables to the roast and let them absorb some of the flavors.

Slow Cooker Pork Tenderloin Ingredients

You only need a few ingredients, besides the pork tenderloin. You might have most of them in your fridge or pantry.

I added onion, minced garlic, barbecue sauce, salt, and pepper.

Sometimes I add either Tabasco or sriracha sauce. But the barbecue sauce I used had all the spice I wanted.

If you want to add vegetables, some good ones are carrots, green beans, onions, corn, and potatoes. You can actually add whatever you want.

How to Make a Slow Cooker Pork Tenderloin

First, I always spray the interior of my slow cooker pot with nonstick spray. That saves a ton of cleanup time.

Second, place the pork tenderloin in the center of the pot. This one was a little bit long, so I curled it around on one end.

Next, sprinkle salt and pepper over the pork. If you’re cutting back on sodium, you can skip the salt.

However, the black pepper gives it a little kick that adds flavor. Or you can use cayenne pepper if everyone can handle the heat.

Then, spoon the minced garlic over the tenderloin. Do your best to distribute it evenly, but it doesn’t have to be perfect.

You can use fresh garlic cloves. This time, I used minced garlic in a jar.

In fact, I find myself using that more and more. It tastes good, and it does a great job of adding flavor.

I’m a big believer of saving as much time as possible.

Sprinkle the onions over the pork. I used frozen onions.

But when I chop a fresh onion, I like them diced really small. You can cut them as small as you want.

Next, pour the barbecue sauce over the pork. Be careful not to knock off the onions and garlic.

Finally, pour the small amount of broth on each side of the pork tenderloin. This helps to keep it from drying out while it’s cooking.

I used chicken broth, but you can use whatever kind of broth you have on hand. You can also make broth by mixing a bouillon cube or crystals with water.

Turn the heat to low and cook for 5 hours.

Or you can cook it on high for 2-3 hours. When you cook pork, you want an internal temperature of 145 degrees F

After it’s done, carefully remove the barbecue pork tenderloin from the slow cooker pot and put it on a plate.

Let it rest for about 15 minutes before you slice it. If it falls apart while you’re removing it, that’s fine. It still tastes wonderful.

An Instant Pot pork tenderloin recipe is basically the same. However, you’ll need to add another cup of broth and cut the cooking time to 5 or 10 minutes, depending on the size of the meat.

You’ll need to do a slow release for 5 minutes, but it’s a very quick process.

If you prefer not to use barbecue sauce, you can also make a pork tenderloin with cream of mushroom soup. It’s up to you whether or not to add the onions and garlic. I do, but that’s because we like a lot of flavors they provide.

How to Reheat Pork Tenderloin

There are actually several ways to reheat a pork tenderloin. You can pop it into your microwave or air fryer if you’re in a hurry.

But my favorite way to reheat the meat is to place it in a frying pan, add a couple of drops of water or oil, and cover it. Turn the heat to medium-low. It should be perfectly warm in just a few minutes.

Slow Cooker Pork Tenderloin

Yield: 6 servings
Prep Time: 5 minutes
Cook Time: 6 hours
Total Time: 6 hours 5 minutes

This slow cooker pork tenderloin is a delicious main dish for any family dinner.

Ingredients

  • One 2-pound pork tenderloin
  • 1/2 cup of diced onion
  • 1 teaspoon of minced garlic
  • 6 ounces of your favorite barbecue sauce
  • 1/2 cup of chicken broth
  • Salt and pepper to taste
  • 2 teaspoons of hot sauce (optional)

Instructions

    1. Spray the inside of your slow cooker pot with nonstick cooking spray to make cleanup easier.
    2. Place the pork in the slow cooker.
    3. Sprinkle the salt and pepper over your pork tenderloin.
    4. Carefully spoon the minced garlic and diced onions on top of it.
    5. Drizzle the barbecue sauce over the tenderloin.
    6. Pour the chicken broth around the tenderloin.
    7. Put the lid on the slow cooker and cook on low for 5 hours or high for 2-3 hours. If you're not sure if it's done, insert a meat thermometer into the thickest part of the meat. The temperature should be 145 degrees F.
    8. Remove the tenderloin from the slow cooker and let it rest for about 10 minutes.
    9. Slice or shred the pork to serve it.

Notes

I used a 6-quart slow cooker, but it doesn't have to be that big. Just make sure you have enough room for the tenderloin.

Cooking pork in your slow cooker will make it fork tender, so it might fall apart when you try to lift it. If you want it intact, remove it with a couple of wide spatulas or spoons and carefully let it rest on a plate before you try to slice it.

You never mentioned the size of crock pot to use. Any suggestions for using two tenderloins?

Hi Maryanne. I used a 6-quart slow cooker, but you can use a smaller one as long as the meat fits in the bottom. You can cook 2 tenderloins at the same time if you have room in your slow cooker. You don't need to adjust the time, but you should double the rest of the ingredients.

Monday 20th of April 2020

Hi Christina. Sorry about that. You'll need to use 1/2 cup of broth. You can use a little bit more if you want, but 1/2 cup keeps it moist, and that's all I use. I hope you enjoy it!
