Comforting Slow Cooker Pork Tenderloin is an easy dinner recipe packed with potatoes and carrots, then slowly simmered in a savory, robust sauce.

Slow cookers are a great way to cook any type of pork. One of our favorites is slow cooker pork chops, but today we’re tackling a pork tenderloin. And it’s easier than ever!

Slow Cooker Pork Tenderloin

Thank you to A.1. Sauce for sponsoring this post. As always, all opinions are my own.

Baby, it’s cold outside! The weather is dipping down colder than I prefer which means it is the time of year that I want to stay cozy and warm under a blanket and not fuss about anything at all. It’s also the time of the year that I enjoy cooking the most. Schedules slow down and dinner cooking adds a warmth to the house that brings a smile to my face.

I’m always looking for new slow cooker recipes to try, giving tweaks and twists to classic, comforting recipes. Pork tenderloin is fantastic cooked in and out of the slow cooker. You just can’t go wrong with this lean cut of meat. For something different, I made a bold-flavored pork tenderloin with new potatoes and chopped carrots slow cooked to fork-tender. I knew my husband and son would quickly fall in love with this meat and potatoes dinner, but I was surprised how much my little Kinslee, who tends to be a picky eater, dug right to this dinner after dance one evening!

Sauce For Slow Cooker Pork

This easy, 5-minute sauce has a bold flavor that just tastes cozy. A.1. Sauce is the star of this recipe. Chefs and home cooks have been using A.1. Sauce since 1862 to bring versatility and bold flavors to dishes. Don’t be fooled…A.1. Sauce is not just for steaks and burgers. You can add the bold flavor to chicken, vegetarian dishes and pork recipes such as this.  A.1. Sauce makes almost everything taste better!

Along with the A.1. Sauce, I added HEINZ Ketchup, a little apple juice for sweetness, garlic, pepper and a hint of coriander to add a warm, nutty flavor. We like to toss in about two tablespoons of diced jalapeno pepper for a little spice, but this is totally optional. You can leave the jalapeno out altogether, or double it if you’d like an extra kick!

Do I need to sear meat before slow cooking?

Searing the meat before slow cooking might seem like a wasted extra step, but I highly recommend not skipping it. Searing helps the meat to develop more of a complex flavor. The meat will get slightly caramelized on the outside as you sear it, which will make the pork have a deep, rich flavor.

To sear the pork, heat a tablespoon of olive oil over medium heat. Once the oil is hot, add the pork tenderloin and allow it to sizzle and sear for a minute or two on each side.

Searing takes less than 10 minutes and it is totally worth the time!

Potatoes, Carrots and Pork

For ease, I used new potatoes in this recipe. New potatoes are small, nearly bite-size potatoes that take virtually no preparation. If you’d like, you can use a larger potato and cut it into chunks before adding it to the slow cooker. I also added carrots and onion. Get creative and add veggies that you know your family will love!

What to Serve with Pork Tenderloin

Since this has veggies included, it is really an easy, all-in-one meal easy enough for busy weeknights. If you’d like, you can add a side of biscuits or rolls and a side salad. This makes the slow cooker pork tenderloin an ideal dinner to serve to guests also.

I tried this before and it was amazing.
Great flavour through everything.
I decided to try 6 thick cut pork loin chops. I didn’t sear them only because they’d cook to quick. I also par boiled the potatoes and carrots.
Once again, everything came out delicious. Thank you for your recipes

I made this pretty much exactly as directed but added a couple of stalks of celery, washed and cut into 1″ chunks. Everything was delicious and fall-apart tender! Thanks for a “keeper” of a recipe, and for the great tip about browning the meat before putting it in the slow cooker. We really enjoyed it!

I had used potatoes in a previous recipe, so, I substituted the potatoes for asparagus, celery, and bell pepper. For the ketchup, I used Whataburger’s spicy ketchup, which had a little bit of Sriacha hot sauce in it. It came out fantastic!!!!

Oh my this is so delish!! I sent this to both my 16 yr old daughter and my husband when I saw this coming through on an email. Hubby made this yesterday and I will tell you it was amazing! It was a bit hot and we didn’t use jalapenos (hubby doesn’t like anything with peppers & jalapenos sometimes makes me ill). I don’t know if next time we should reduce the pepper and maybe the A1 in crockpot but something was making it a little too hot. Or maybe there’s something to add more of to “cool” it off… Read more »

Holy Cow, this looks amazing! Your recipes are some of the ones I feel comfortable making and serving to anyone without having to try before hand. Thank you for all the effort you put into your work! I’ve trusted many recipes prior to making them and serving them and realized something was wrong. That has rarely happened with yours and I’m sure it was something I did wrong. This is definitely on my must cook list!
