Dim sum dumplings, those bite-sized pockets of deliciousness, are a true culinary delight. Whether you’re savoring steamed har gow, pan-fried potstickers, or juicy soup dumplings, these delicacies offer a symphony of flavors and textures. But what happens when you have leftovers? Reheating dim sum dumplings can be tricky, as the goal is to restore them to their former glory without sacrificing their delicate textures and flavors. This guide provides a comprehensive overview of the best methods for reheating various types of dim sum dumplings, ensuring a satisfying and authentic dining experience, even the second time around.
Understanding Dim Sum Dumpling Types and Their Textures
Before diving into reheating techniques, it’s essential to understand the different types of dim sum dumplings and how their unique characteristics influence the reheating process. Different cooking methods impact the final product, which in turn affects how they should be reheated.
Steamed Dumplings: Har Gow and Siu Mai
Steamed dumplings like har gow (shrimp dumplings) and siu mai (pork dumplings) are characterized by their delicate wrappers and tender fillings. Har gow wrappers are traditionally made with tapioca starch, giving them a translucent and slightly chewy texture. Siu mai wrappers, typically made with wheat flour, offer a slightly firmer bite. The primary challenge in reheating steamed dumplings is preventing the wrappers from becoming soggy or overly sticky.
Pan-Fried Dumplings: Potstickers and Gyoza
Potstickers (also known as gyoza in Japanese cuisine) boast a delightful combination of textures: a crispy, golden-brown base and a soft, steamed upper portion. These dumplings are typically filled with a mixture of ground meat, vegetables, and seasonings. Reheating potstickers requires a method that can revive both the crispiness and the tenderness, without drying out the filling.
Soup Dumplings: Xiao Long Bao
Xiao long bao, or soup dumplings, are a culinary marvel filled with flavorful broth and a savory meat filling. Their delicate wrappers hold a treasure trove of liquid, which can easily be lost or compromised during reheating. The key to reheating soup dumplings is to preserve the integrity of the wrapper and the precious soup inside.
Deep-Fried Dumplings: Wu Gok (Taro Dumplings)
Wu Gok, or taro dumplings, are deep-fried to a golden brown perfection, boasting a crispy exterior and a soft, fluffy taro filling. Reheating these dumplings requires careful attention to prevent them from becoming greasy or losing their crispness.
The Best Methods for Reheating Dim Sum Dumplings
Now that we’ve explored the different types of dumplings, let’s examine the most effective reheating methods for each variety, ensuring optimal texture and taste.

How does steaming compare to other reheating methods for dim sum dumplings?
Steaming is widely considered the best method for reheating dim sum dumplings because it helps retain their original texture and moisture. The gentle heat of the steam prevents the delicate wrappers from drying out or becoming rubbery, which can often happen with methods like microwaving or baking. It also helps to reactivate the fillings, ensuring they remain juicy and flavorful, similar to when they were freshly prepared.
Other methods, such as microwaving, can result in uneven heating and a gummy texture. Baking can dry out the wrappers, making them hard and brittle. Pan-frying, while capable of achieving a crispy exterior, can also make the dumplings oily and doesn’t replicate the soft, steamed texture that is characteristic of most dim sum. Steaming provides the most authentic and satisfying reheating experience.
What is the best way to reheat frozen dim sum dumplings?
The best way to reheat frozen dim sum dumplings is to steam them directly from frozen. Do not thaw them beforehand, as this can lead to a soggy and uneven texture. Place the frozen dumplings in a steamer basket lined with parchment paper or cabbage leaves to prevent sticking.
Steam the frozen dumplings for a longer period compared to refrigerated ones, typically around 12-15 minutes, or until they are heated through. The exact steaming time will depend on the size and type of dumpling, so it’s always a good idea to check their internal temperature with a food thermometer to ensure they reach a safe temperature of 165°F (74°C).
Can I reheat dim sum dumplings in the microwave?
While not the preferred method, you can reheat dim sum dumplings in the microwave if you are short on time. However, it’s important to take precautions to prevent them from becoming rubbery and dry. Place the dumplings on a microwave-safe plate and add a small amount of water (about a tablespoon) to the plate.
Cover the plate with a microwave-safe lid or plastic wrap, leaving a small vent for steam to escape. Microwave on medium power in short intervals of 30-60 seconds, checking frequently to avoid overcooking. The water helps to create a steamy environment, minimizing dryness, but the texture will likely be different from freshly steamed dumplings.
What is the ideal internal temperature for reheating dim sum dumplings?
The ideal internal temperature for reheating dim sum dumplings is 165°F (74°C). This ensures that any bacteria present are killed and the dumplings are safe to eat. Using a food thermometer to check the internal temperature is highly recommended, especially when reheating frozen or larger dumplings.
Insert the thermometer into the center of the filling to get an accurate reading. If the temperature is below 165°F (74°C), continue reheating for a short period and check again. Overheating can lead to a dry and tough texture, so it’s important to monitor the temperature carefully.
How do I prevent dumplings from sticking to the steamer basket?
Preventing dumplings from sticking to the steamer basket is crucial for a successful reheating process. The best way to achieve this is to line the steamer basket with parchment paper, specifically perforated parchment paper designed for steaming. The perforations allow steam to pass through while the paper prevents the dumplings from direct contact with the basket.
Alternatively, you can use cabbage leaves or lettuce leaves as a lining. These natural options not only prevent sticking but also impart a subtle, pleasant flavor to the dumplings. Lightly oiling the steamer basket before placing the dumplings can also help, but it’s not as effective as using a liner.
What if my dim sum dumplings have different fillings; how should I adjust the reheating time?
When reheating dim sum dumplings with different fillings, it’s important to consider that some fillings may require slightly different reheating times. Fillings containing ingredients like seafood or larger pieces of meat may take longer to heat through than vegetable-based fillings. To ensure even reheating, arrange the dumplings in the steamer basket so that those with similar fillings are grouped together.
Monitor the dumplings during the reheating process and test the internal temperature of a dumpling from each type of filling to ensure they all reach 165°F (74°C). If one type of filling seems to be taking longer, you can carefully move the other dumplings to a warmer part of the steamer while allowing the slower-heating dumplings to continue steaming.
How long can I safely store reheated dim sum dumplings?
Reheated dim sum dumplings should be consumed immediately for the best quality and safety. However, if you have leftovers from the reheated batch, it’s crucial to store them properly and consume them within a limited timeframe. Allow the reheated dumplings to cool down completely before storing them in an airtight container.
Refrigerate the cooled dumplings promptly, ideally within two hours of reheating. Consume the reheated and refrigerated dumplings within 1-2 days. It is not recommended to reheat the dumplings a second time, as this can further degrade their texture and increase the risk of bacterial growth.
