How to Store or Freeze This Dish
Allow the green beans to cool completely before storing. This prevents condensation, which can make them soggy.
Transfer the cooled green beans to an airtight container. Make sure the container is clean and dry to maintain the freshness of the vegetables.
Store the container in the refrigerator. The spicy Chinese mustard green beans will stay fresh for up to 3-4 days.
For freezing, spread the cooled green beans in a single layer on a baking sheet. This prevents them from sticking together.
Place the baking sheet in the freezer for about 1-2 hours, or until the green beans are frozen solid.
Once frozen, transfer the green beans to a freezer-safe bag or container. Label the bag with the date to keep track of freshness.
When ready to eat, thaw the green beans in the refrigerator overnight. Reheat in a skillet over medium heat until warmed through, adding a splash of soy sauce if needed to refresh the flavors.
Avoid reheating in the microwave as it can make the green beans mushy. Opt for stovetop reheating for the best texture and taste.
How to Reheat Leftovers
Microwave: Place the green beans in a microwave-safe dish. Cover with a microwave-safe lid or plastic wrap, leaving a small corner open for steam to escape. Heat on high for 1-2 minutes, stirring halfway through. Check for desired warmth and texture.
Stovetop: Heat a skillet over medium heat. Add a small amount of vegetable oil or a splash of water to prevent sticking. Add the green beans and stir occasionally for 3-5 minutes until heated through.
Oven: Preheat the oven to 350°F (175°C). Spread the green beans in a single layer on a baking sheet. Cover with aluminum foil to retain moisture. Bake for 10-15 minutes, stirring halfway through, until heated evenly.
Air Fryer: Preheat the air fryer to 350°F (175°C). Place the green beans in the air fryer basket in a single layer. Heat for 3-5 minutes, shaking the basket halfway through to ensure even reheating.
Steamer: Place the green beans in a steamer basket over boiling water. Cover and steam for 3-5 minutes until heated through. This method helps retain the crisp-tender texture.
