If you’ve tuned in to Instagram Stories, you’ll know that pork tenderloin makes a weekly appearance at our house. It’s seasoned simply with salt, pepper and garlic powder, then roasted and glazed with my go-to Thai sweet chili sauce for one seriously lip-smacking transformation from humble “other white meat” to family favorite entrée.
My dear Sweet and Sour Pork Tenderloin, I don’t want to be the bearer of bad news, but you have some serious competition in the dinner department. And we all have Justin Chapple to thank for putting the “tender” in “tenderloin!”
Justin and I met awhile back at the Aspen Food & Wine Festival and I’ve been a fan of his fresh and approachable take on cuisine ever since. His cookbook, Just Cook It! serves up 145 recipes with an emphasis on ease, from Caramelized Peach French Toast Casserole and Chicken Enchilada Stacks to Ravioli Lasagna and Free-Form Apple Tart.
As a working mom of 4, you better believe that I am all for meals that are easy, fast, fresh and totally family-friendly.
But in all my years of cooking, never had I ever thought of slicing a pork tenderloin lengthwise then into small pieces before cooking it. Mind legit blown.
The result is the most tender pork I have ever tasted—in a restaurant or in my home kitchen. Toss in some crisp asparagus and a hearty portion of freshly cracked black pepper and you have a 30-minute meal that tantalizes your taste buds and takes the stress out of dinner prep.
Besides cooking oil, you need just five simple ingredients for this pork stir fry recipe. I like to garnish the dish with toasted sesame seeds and sliced scallions, but these are totally optional.
- Pork tenderloin: This lean cut of pork is perfect for stir-frying as it cooks quickly and remains tender. Slice the tenderloin thinly against the grain to ensure maximum tenderness.
- Low-sodium soy sauce: I find using regular soy sauce can often result in overly salty dishes, so I prefer opting for a low-sodium variety. If you’re gluten-sensitive, tamari sauce is a great alternative.
- Cornstarch: Not only does it help to thicken the sauce, but it’s also my go-to ingredient for tenderizing meat. Similar to my recipe for Mongolian beef, this recipe stars an abridged version of a classic Chinese cooking technique called velveting.
- Black pepper:I recommend using freshly ground black pepper for the best flavor, but pre-ground pepper works in a pinch (and the results will be just as delicious!). Adjust the amount according to your taste buds.
- Asparagus: I love the crunch and hint of sweetness asparagus brings to this stir-fry. But don’t be afraid to mix it up! Swap it out for broccoli, bell peppers or snap peas. Just be sure to adjust the cooking time based on the vegetable you choose.
- Vegetable oil: Because we’re cooking at high heat, it’s essential to use an oil with a high smoke point. I prefer vegetable oil because of its neutral flavor, but canola or peanut oil also work. Avoid using olive oil because its lower smoke point may lead to a bitter taste.

- Cut the pork. Use a sharp knife and try to slice it as thinly and evenly as possible. This ensures quick and even cooking.
- Let it marinate. In a large bowl, mix the pork with the soy sauce, cornstarch, black pepper and a pinch of salt. Allow it to marinate for at least 15 minutes to allow the flavors to penetrate the meat. For even more flavor, you can marinate it for up to 30 minutes.
- Cook the pork. Heat a large skillet over high heat. Add 2 tablespoons of the vegetable oil and swirl to coat the pan. Add the pork and spread it into an even layer. Cook the pork, undisturbed, until it is browned on the bottom, 3 to 5 minutes, then continue cooking the pork while stirring for an additional 2 minutes.
- Using a slotted spoon, transfer the pork to a plate.
- Cook the asparagus. Add 1 tablespoon of vegetable oil to the pan and reduce the heat to medium-high. Add the asparagus and a pinch of salt and cook, stirring, until the asparagus is crisp-tender, about 3 minutes.
- Return the pork to the pan and cook, stirring, until hot, about 1 minute.
Serve this with steamed coconut rice or your favorite Asian-style noodle. Or, complete your feast with my favorite Cauliflower Fried Rice with Pineapple!
- Stir-frying is a fast cooking method so have everything prepped and ready to go before you fire up the flames.
- When slicing the pork tenderloin, aim for thin and uniform slices. This ensures that it cooks quickly and evenly.
- Test to make sure your oil is hot before you begin cooking. You can test it by dipping the end of a wooden spoon into the oil – if bubbles form around it, the oil is ready to go. This is important for achieving perfectly seared pork slices.
- Avoid overcrowding the pan, which can lead to steaming instead of browning. If you need to, cook the pork in batches.
- Taste the dish as you go and adjust the seasoning levels to suit your preferences. Add more black pepper for extra kick or soy sauce for a saltier flavor.
Frequently Asked Questions
While the pork is best served immediately after cooking for optimal flavor and texture, you can prepare the ingredients in advance to save time. However, I recommend cooking the pork just before serving to ensure it’s hot and fresh.
While marinating the pork adds flavor and helps tenderize the meat, you can still make a delicious dish without it. However, I highly recommend marinating the pork for at least 15 minutes to enhance its flavor and texture.
Yes, you can use frozen asparagus if fresh is not available. Simply thaw the frozen asparagus before cooking and adjust the cooking time as needed. Keep in mind that frozen asparagus may be slightly softer in texture compared to fresh, but it will still work well in the recipe.
