Slow Cooker Pineapple Pork Loin

Published on January 21, 2016 By Lauren

Sometimes it pays to simplify.  This recipe only has 5 ingredients, but it’s loaded with flavor and yum!  Pineapple pork loin is not a new concept, but this easy version takes all the complicated steps and makes your meal truly amazing in one afternoon.

I came up with this recipe when I was wanting a little spice and a little sweet.  Do you ever want to just mix it up!?

Pork is so flexible.  It goes well with savory and sweet, so I knew that this was a perfect start.  Pineapple is perfect because it’s a little acidic and so sweet when it’s ripe.  Pineapple juice flavors the meat and even tenderizes it while it cooks.  Yes!  Pineapple is a natural meat tenderizer.  Throwing the crushed red pepper in was a no-brainer.  The perfect spark of flavor!

I didn’t add any extra oil or juice to this recipe because the pineapple chunks were fresh and everything came out perfectly!  If you use frozen or canned pineapple, you might want to add a tablespoon of juice or water to the slow cooker.  This will make sure that everything cooks up nice and tender.

Leave the pork loin whole before cooking.  That’s right: Don’t cut it, chop it, or slice it.  Leaving it whole will allow it to stay tender and juicy.  Trust me.  Serving up these delicious slices at dinnertime will be worth the wait.

Success note: Make sure that you don’t overcook the pork.  The internal temperature should reach 145 degrees Fahrenheit for a perfectly cooked pork loin.

Of course, like most of our slow cooker recipes, you can prep this and freeze it ahead of time.  It won’t freeze as flat as the other meals so make sure you have space for the pork loin in your freezer.

You will not believe that this Slow Cooker Pineapple Pork Loin recipe only has 5 ingredients.  No fuss!  Just flavor!
