This Slow Cooker Spicy Pork Loin is made with a simple ingredients and is bursting with flavor!pinterestDon’t we all love our slow cookers? Sometimes I feel like I don’t use mine often enough. And then I make something totally delicious without much effort, and ask myself why in the world am I not using it for every meal? 🙂

Well, that’s probably because the Instant Pot came into our life!! This no-stir Instant Pot risotto, for example, is a life-changer!

But let’s focus on the slow cooker for a minute, it’s the star of the kitchen tools today. We’re going to make the most delicious and versatile slow cooker pork tenderloin with a nice kick of spice! I hope you like to sweat a little. Just kidding, it’s really not that spicy, just has a nice kick!

The ingredient list isn’t long, but everything brings a little something to the dish. Let’s get through them individually, so you know why we’re using them, and if you can swap any of them.

Slow Cooker Pork Tenderloin Recipe

  • Sweet onion – It’s much milder and sweeter than regular yellow onion, adding a touch of onion sweetness to the sauce. You can substitute yellow onion if you want to.
  • Brown sugar – It brings beautiful balance in our spicy gravy. I prefer brown sugar over granulated sugar in this dish.
  • Red wine vinegar – This is another important ingredient for well-rounded flavor in our slow cooker pork loin. Though any kind of vinegar would work, I like the flavor of red wine vinegar the most. The best substitute is apple cider vinegar.
  • Soy sauce – I always use regular soy sauce vs low sodium soy sauce. Did you know that low sodium soy sauce may have less salt, but it has more chemicals? It’s true, that’s why it’s better just dilute the regular soy sauce with water to bring the salt down.
  • Hot sauce – This is, of course, the crucial ingredient in this recipe, and I highly recommend using YOUR favorite hot sauce. I personally like Frank’s RedHot.
  • Cornstarch – It’s a thickener for the gravy. Unless you like runny sauce, I wouldn’t recommend omitting it.

Through multiple recipe testing, as you can imagine, I’ve got ton of leftovers, and I had fun repurposing it into different meals, like pulled pork sandwich, pulled pork baked potatoes, and spicy pulled pork egg rolls (not pictured, but I shared the process in my Instagram featured stories).

Told ya, it’s pretty versatile!! You’d totally appreciate the leftovers.

    Very easy and my entire family liked it which is pretty impossible! The gravy was a bit too sweet for my liking even though I added extra salt. I may omit the sugar next time. Thank you!

    A little confused about the cut of pork – loin and tenderloin are different. You mention both. I have a 3 pound pork loin – same cooking time as the little tenderloins?

    1. Shawn

      A pork loin should work for this recipe, although allow for plenty of cooking time in case you need a little longer to get it tender. Hope this helps!

  3. Joy

    Just curious if there’s a reason you place the onions on the bottom. My thought process is that the onion flavor would penetrate the loin better by being on top but what do I know? 🙂

    Looks delicious, can’t wait to make this! Just wondered if you are using 2 pieces of pork tenderloin in this recipe? When I buy pork tenderloin, it comes with 2 pieces in the pkg. & I would like to use both pieces in this recipe. Do I need to double the sauce ingredients for 2 pieces? Thank you!

    1. Shinee D

      Hi, Janet. Yep, mine came with 2 pieces as well. As long as you’ve got around 3lbs of tenderloin, you don’t need to double the sauce. Hope you’ll enjoy it. And let us know if you try this recipe.
