Most of the ingredients in this recipe are easy to find at your local supermarket. The only ones you might want to look for carefully are oyster sauce and cornstarch. Oyster sauce is a thick, savory sauce that adds a nice depth of flavor, and you can usually find it in the Asian foods aisle. Cornstarch is a common thickener that helps the sauce get just the right texture.

OYSTER SAUCE: A rich, slightly sweet sauce made from oysters that adds depth to the stir-fry.

Technique Tip for This Stir-Fry
One of the most important moves in this Pork and Green Bean Stir-Fry Recipe is how you stir-fry the pork and green beans. Stir-frying means cooking food quickly in a hot pan while moving it around a lot. Here’s how to do it step by step:
- Heat your wok or pan over high heat before adding any oil. This makes sure the food cooks fast and gets a nice color.
- Add the vegetable oil and swirl it around so the whole surface is coated.
- Toss in the minced garlic and stir it for about 30 seconds until it smells amazing but doesn’t burn.
- Add the thinly sliced pork tenderloin and keep stirring or tossing it so every piece touches the hot pan. This helps the pork brown evenly and stay juicy.
- When the pork looks cooked, add the trimmed green beans and keep stirring for a few more minutes. Moving the food constantly stops it from sticking or burning.
Doing this right makes your stir-fry taste better because the pork gets a nice brown crust, and the green beans stay crisp and fresh instead of soggy. Plus, it cooks everything fast, so the flavors stay bright and yummy.
A little secret I learned is that if you don’t keep the food moving, the pork can get tough or dry. At first, I didn’t stir enough and ended up with some burnt bits, which wasn’t fun. Now, I make sure to keep my hands busy with the spatula or tongs, and it really makes a difference. Also, slicing the pork tenderloin thin helps it cook quickly and stay tender, which is perfect for stir-frying.

How to Store or Freeze This Stir-Fry
Allow the pork and green bean stir-fry to cool to room temperature before storing. This helps prevent condensation, which can lead to sogginess.
Transfer the stir-fry to an airtight container. For best results, use a shallow container to ensure even cooling and reheating.
Store the container in the refrigerator if you plan to consume the dish within 3-4 days. This will keep the pork tender and the green beans crisp.
For longer storage, place the stir-fry in a freezer-safe container or a heavy-duty freezer bag. Ensure you remove as much air as possible to prevent freezer burn.
Label the container with the date of storage to keep track of its freshness. The stir-fry can be frozen for up to 2 months without significant loss of flavor or texture.
When ready to enjoy, thaw the frozen stir-fry in the refrigerator overnight. This gradual thawing helps maintain the dish's quality.
Reheat the stir-fry in a wok or skillet over medium heat. Add a splash of water or soy sauce to refresh the flavors and prevent drying out.
Stir occasionally to ensure even heating, and serve hot with freshly cooked rice for a delightful meal.
How to Reheat Leftovers
Use a microwave: Place the pork and green bean stir-fry in a microwave-safe dish. Cover it with a microwave-safe lid or plastic wrap, leaving a small vent for steam to escape. Heat on medium power for 1-2 minutes, then stir. Continue heating in 30-second intervals until warmed through. This method is quick and retains moisture, but be cautious not to overheat, which can make the pork tough.
Reheat on the stovetop: Add a splash of vegetable oil or a bit of water to a non-stick skillet. Heat over medium heat and add the stir-fry. Stir occasionally to ensure even heating. This method helps maintain the texture of the green beans and keeps the pork tender.
Use an oven: Preheat the oven to 350°F (175°C). Place the stir-fry in an oven-safe dish and cover with foil to prevent drying out. Heat for about 10-15 minutes, checking occasionally. This method is ideal if you want to reheat a larger portion without using the microwave.
Try a steamer: If you have a steamer basket, place the stir-fry in it and steam over boiling water for 5-7 minutes. This gentle method helps retain moisture and keeps the vegetables vibrant.
Use an air fryer: Preheat the air fryer to 350°F (175°C). Place the stir-fry in the basket, ensuring it's spread out evenly. Heat for 3-5 minutes, shaking the basket halfway through. This method can add a slight crispiness to the green beans while keeping the pork juicy.
