Sweet and Sour Pork

By Kate Shungu ● Updated May 20, 2025

Sweet and Sour Pork Tenderloin is a lighter take on a classic favorite, with no frying required. Tender slices of pork are coated in a tangy, flavorful sauce that hits the perfect balance of sweet and savory.

Kate’s Recipe Rundown

I love a good 30-minute dinner that the whole family enjoys, and this Sweet and Sour Pork delivers on both! 

The recipe is adapted from a 1970’s church cookbook (actually, a few cookbooks had a very similar recipe). The pork is SO tender and juicy, and I love using a lean cut like pork tenderloin because it’s packed with protein AND has great flavor.

And, when you purchase pork at any grocery store in the United States, you’re supporting family farms in Iowa and across the United States. That’s a win-win for me as the granddaughter of a farmer. Thank you to Iowa Pork for sponsoring this post!

Enjoy! Kate

Ingredients

pork tenderloin, pineapple, bell pepper, and other ingredients.
  • I chose pork tenderloin for this dish because it’s lean and cooks quickly (a 30-minute dinner must-have!)
  • You can use whatever color of bell pepper that you have on hand
  • Canned pineapple is key here—we will use the juice for the sauce.
  • Don’t have dry mustard? A squirt of regular or dijon mustard works well in its place.
  • You can use apple cider vinegar like I did, or white vinegar works, too.

How to Make Sweet and Sour Pork (Stir Fry Method)

  1. Start by sautéing the sliced peppers and onions in a skillet until soft.
  2. Then, sauté the pork tenderloin until lightly browned on both sides.
  3. Whisk the sauce ingredients together.
  4. Add the sauce to the pork, along with the sautéed peppers and onions, and the pineapple. Garnish with green onions and enjoy!

How to know when the Pork is done

Since this meal cooks quickly, we’ll use a simple method to ensure the pork stays juicy but is still cooked to a safe internal temperature.

Simply put, we’ll sauté the pork until it’s browned on both sides. Then, we’ll briefly cook it in the sweet & sour sauce until it reaches 145°F. Three minutes later, it’s ready to eat! You can read more about cooking pork to the perfect temperature with this handy guide from Pork.org.

Notes

You can use leftover pork in place of the tenderloin, if you’d like. Give it a quick stir fry in the oil before adding the other ingredients. 
Don’t have dry mustard? Add a teaspoon or two of yellow mustard or dijon mustard, or just leave it out. 
Leftovers will keep in the refrigerator for up to 5 days. You can also freeze this dish, then defrost and reheat when you’re ready to enjoy it again.
