Pork Tenderloin with Ah So Sauce

My family has been making some version of Ah-So pork for ages. It’s one of those easy, reliable recipes that everyone loves. All it needs is a side of white rice and you have a fabulous meal in under an hour!

Ah So Pork

Of course Ah-So sauce is the base of the recipe and the star of the show, in all its neon red, sweet-and-sour glory. If you’re not familiar with this sauce, it’s a jarred Chinese BBQ sauce that’s popular in the northeastern United States, made with corn syrup, miso, garlic, etc. It tastes sweet, salty, garlicky, and slightly sour. If you can’t find it in your local grocery store (in the Asian foods section), here’s a link to it on Amazon and Walmart.

To add a little more depth and dimension to our Ah So pork tenderloin, I mix it with soy sauce, toasted sesame oil, brown sugar, ground ginger, and garlic (you can use fresh garlic or garlic powder). *Note: While the sauce tastes best with all of those ingredients, this recipe is incredibly forgiving. So if you’re missing one or two of the ingredients (the Ah-So sauce is a must), you’ll still be able to turn out a meal that tastes great.

Once you’ve whisked up your Ah So sauce mixture, it’s time to marinate the pork. Marinating gives the pork time to really soak up some of that delicious sauce, but if you don’t have time to marinate, fear not! The pork will still turn out great if you simply slather on the sauce and bake it immediately. To marinate: Pour the Ah so mixture into a gallon-sized plastic bag, add your pork tenderloins, press out as much air as possible, and seal the bag. Turn the bag a few times to coat the pork in marinade and refrigerate for at least 30 minutes and up to 24 hours, flipping the bag halfway through to make sure the pork marinates evenly.

When you’re ready to cook the Ah So pork, line a baking pan with aluminum foil, remove the tenderloins from the marinade (discard the liquid), place the tenderloins in the center of the pan, and bake at 350 degrees F for 40-50 minutes. Remove from the oven and let the pork rest for 10 minutes before slicing. Serve with any green vegetable you like and a side of rice.

Enjoy!

      Hi Ash! Sorry, I should have given more info on the sauce! It’s a jarred Chinese BBQ sauce that’s popular in the northeastern United States, made with corn syrup, miso, garlic, etc. It tastes sweet, salty, garlicky, and slightly sour. If you can’t find it in your local grocery store (in the Asian foods section), here’s a link to it on Amazon and Walmart.

    OMG, I didn’t think anyone else knew about Ah So Sauce. Growing up always looked forward to pork chop night because we got to have Ah So Sauce on them. MNM. The flavor is un to itself. I have taken it to the grill for grilled pork chops but I think I will bring the pork tenderloin along for the ride now. Thanks for the recipe!!!! HOW GOES THE COLIC?

    Kinda hard to try a recipe that doesn’t tell you how to make the main sauce ingredient. Disappointed in this post.

    Ah So sauce is a Northeast specialty, you should say this and offer info on how to make your own, since your readers live all over and most cant purchase it in their regular stores. That being said, you obviously disappointed all those who have no idea what you’re suggesting(mixing it with other ingredients). Next time, please be thoughtful when giving out a recipe that you truly don’t know the origins of. Now,can you share what to do for those of us who dont have Ah So sauce in their grocery stores? Thank you.

      Hi Lisa,
      Sorry, I should have given details on what the sauce is! My mistake. I have not made a homemade version of it myself so I won’t be able to provide a good recipe swap, but here are links to find the product on Amazon and Walmart.
