Easy and versatile, this Slow Cooker Spicy Pork Loin is easy to prepare and can be served in many different ways. You’ll love the spicy kick in every bite, and leftovers are equally delicious!
Don’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? 🙂
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.
