There is no fixed standard for the cooking time of quick-frozen green beans. It mainly depends on whether they are defrosted and the cooking scenario (cooked alone / cooked with other ingredients). It is usually between 2-8 minutes. The key is to cook them until they are "emerald green, no raw taste, crispy and tender" to avoid boiling them for too long and causing them to become soft and rotten. How to buy Tangshan quick-frozen green beans

1. Unthawed quick-frozen green beans: cook for 3-8 minutes (depending on the scene)
There is ice inside the unfrozen green beans. The time needs to be adjusted according to whether they are paired with other ingredients. Boil them in boiling water first, which can quickly lock in moisture and color.
Cook separately (cook and then serve cold/quick stir-fry)
Once the water comes to a boil, add the unthawed green beans and cook over medium heat for 3-5 minutes.
Judgment criteria: The color of the green beans changes from light green to deep emerald green, they can be easily pierced with chopsticks, there is no icy residue or raw bean smell when biting open, and they are crisp and tender before being fished out.
Cook with other ingredients (soup/rice stew)
If it is cooked with cooking-resistant ingredients such as ribs and corn (such as ribs soup), add unthawed green beans when cold water is put into the pot, and cook for 5-8 minutes (adjust according to the doneness of the main ingredients).
If you simmer it with rice, place it directly on the rice. After the rice is cooked (about 20 minutes), the green beans will be cooked at the same time, so there is no need to control the time.
2. Thawed quick-frozen green beans: cook for 2-3 minutes (avoid making them too soft)
The thawed green beans have softened, and the cooking time needs to be greatly shortened to prevent the taste from changing. This is suitable for scenarios where "quick meal preparation" is pursued.
Cook separately (cook and serve cold)
After the water boils, add the thawed green beans and cook over medium heat for 2-3 minutes.
Note: There may be water on the surface of the green beans after thawing. It is recommended to drain them before putting them in the pot to avoid excessive water leakage during cooking, which will affect the taste.
Pair it with easy-to-cook ingredients (such as shrimps and eggs)
When cooking with ingredients that can be cooked in 1-2 minutes, such as shrimps and eggs, when the main ingredients are almost cooked (such as shrimps turning red), add thawed green beans, cook for 1-2 minutes and then turn off the heat to ensure that all ingredients are cooked at the same time and the green beans are not rotten.
3. 3 Key Tips to Avoid Overcooking
Don’t cook them in cold water for a long time: Cooking them in cold water will keep the green beans in a low-temperature environment for a long time, making them easy to soften and turn yellow. Boil them in boiling water first, as they can quickly set their shape at high temperatures and lock in their crispiness.
Add "color-protecting ingredients": add a little salt (about 1g) and a few drops of cooking oil after the water is boiled to keep the green beans green and avoid dull color after cooking.
Pour cold water after cooking: Regardless of whether they are defrosted or not, take out the cooked green beans immediately and rinse them with cold water for 10 seconds. This can quickly cool down the beans and further lock in the crispy and tender taste. It is especially suitable for cold salad or subsequent quick frying.
