Tools and Equipment

To bring our Vietnamese Winter Melon Soup, or Canh Bí Đao, from the recipe to your table, you’ll need a selection of kitchen tools that will make the cooking process smoother and more efficient. Let’s dive into the essentials you’ll want to have handy before we get started on this comforting, traditional dish.

Cutting Board and Sharp Knife

First up, a durable cutting board and a sharp knife are indispensable. You’ll be doing a fair bit of chopping and slicing, especially the winter melon, onions, and any herbs you choose to garnish with. A sharp knife not only ensures precision but also safety in the kitchen.

Large Pot or Dutch Oven

The backbone of our Vietnamese Winter Melon Soup is the chicken broth, which we’ll be simmering to perfection. For this, a large pot or a Dutch oven is your best bet. It should be big enough to comfortably hold all the broth and ingredients, allowing them to mingle and infuse the broth with a rich array of flavors.

Ladle and Stirring Spoon

A sturdy ladle will be crucial for serving the soup, while a long-handled wooden spoon or a stainless steel stirring spoon will ensure you can stir your ingredients without the risk of burning your hands or the soup sticking to the bottom of the pot.

Fine Mesh Strainer

Though optional, a fine mesh strainer can come in handy if you’re looking to achieve a clear broth. It’s perfect for skimming off any impurities that rise to the surface during the initial boil of your chicken broth, ensuring a pristine base for your soup.

Measuring Cups and Spoons

Accurate measurements can make or break a dish, and that’s no different for our Vietnamese Winter Melon Soup. Measuring cups and spoons will help you add the perfect amount of fish sauce for umami, salt for seasoning, and any other ingredients to balance the dish’s sweet, savory, and aromatic profiles.

Vegetable Peeler

Finally, a vegetable peeler will make prepping the winter melon a breeze. It’s the quickest, most efficient way to remove the melon’s thick skin without losing too much of the flesh, ensuring you have maximum yield and flavor from your key ingredient.

Prep Work

Before we dive into the heart of cooking our Vietnamese Winter Melon Soup, a bit of prep work is necessary. This not only makes our cooking process smoother but also enhances the flavors of our dish.

Preparing the Winter Melon

First things first, let’s tackle the star ingredient—the winter melon. With our cutting board and sharp knife at the ready, we begin by peeling off the green skin. We aim for removing just the outer layer, preserving as much of the white flesh as possible. Next, we cut the melon into two halves, scoop out the seeds and any fibrous parts from the center, then chop into bite-sized cubes. It’s a good idea to rinse these pieces under cold water to remove any residual sap, ensuring a cleaner taste in our soup.

Making the Filling

Although our soup’s version today is simple and focuses on the purity of the winter melon’s flavor, some variations include a meaty filling for an added layer of texture and richness. Here, we’ll mix ground pork with finely chopped scallions, a touch of fish sauce for that umami depth, and a sprinkle of pepper for seasoning. It’s important to mix until the ingredients are just combined—overworking the mixture can make the filling tough. Once mixed, we can set this aside until we’re ready to add it to our broth, creating delightful, meaty morsels that complement the subtle sweetness of the winter melon perfectly.

Cooking Instructions

Let’s get cooking! We’ll guide you through each step to create a comforting bowl of Vietnamese Winter Melon Soup, ensuring every spoonful is imbued with the perfect blend of flavors and textures.

Starting the Soup Base

First, place a large pot over medium heat and pour in about 6 cups of chicken broth. If you’re looking for an extra depth of flavor, homemade broth is our go-to choice, but store-bought works just fine in a pinch. Bring the broth to a gentle simmer. This is the foundation of your soup, so you want to make sure it’s beautifully flavored from the start. At this stage, we add a touch of fish sauce for that quintessentially Vietnamese umami flavor, along with a pinch of salt to taste. It’s crucial not to let the broth boil too vigorously; a gentle simmer ensures that all the flavors meld together perfectly without evaporating too much of the liquid.

Cooking the Winter Melon

Once your broth is simmering nicely, it’s time to add the star ingredient—winter melon. You’ve already prepped it by peeling, de-seeding, and cutting it into bite-sized cubes. Add these pieces to the broth. Winter melon takes a little while to cook through, usually around 15-20 minutes, but you’ll know it’s done when it becomes translucent and tender, yet still holds its shape. This is the moment where the melon’s subtle sweetness seeps into the broth, creating a delightful harmony of flavors. Stir gently occasionally to ensure even cooking and to prevent any pieces from sticking to the bottom of the pot.

Finalizing the Soup

As the winter melon nears the end of its cooking time, it’s the perfect moment to add the meaty filling that we’ve prepared with ground pork, minced scallions, fish sauce, and a dash of pepper. Take small portions of the mixture and form them into little balls, then gently drop them into the soup. These will cook relatively quickly, needing about 5-7 minutes to become fully cooked. They’re ready when they float to the top and are no longer pink inside. Give the soup a gentle stir to distribute the ingredients evenly. Lastly, adjust the seasoning with salt and pepper if needed. It’s always a good idea to taste and tweak; this ensures your soup is perfectly seasoned to your liking.

The final touch involves a sprinkle of thinly sliced scallions, adding not only a pop of color but also a slight crispness that contrasts beautifully with the soft textures of the winter melon and pork balls. Serve the soup hot, either as a stand-alone meal or as a part of a larger feast. Enjoy the comforting warmth and rich flavors that embody the essence of Vietnamese cuisine.

Serving Suggestions

After you’ve meticulously prepared the Vietnamese Winter Melon Soup, Canh Bí Đao, with its comforting broth and tender morsels of pork and melon, serving it in a way that enhances its warmth and richness is essential. Below, we share our favorite ways to turn this delightful soup into a full meal.

Pair with Rice

The subtle sweetness and comforting liquid of Canh Bí Đao make it an excellent pairing with plain jasmine rice. Serve the soup as a side to a bowl of steamed rice, allowing the grains to soak up the flavorsome broth, creating a simple yet satisfying meal.

Add Herbs for Freshness

A sprig of fresh herbs can transform the soup with a burst of fragrance and flavor. We love adding chopped cilantro or Thai basil right before serving. Not only do these herbs elevate the taste, but they also add a pop of color to your dish.

Side Dishes to Consider

For a well-rounded meal, consider serving the soup alongside other Vietnamese dishes. Spring rolls or a fresh vegetable salad with a tangy dressing can add textural contrast and a refreshing counterpoint to the mellow, meaty flavors of the soup.

Beverage Pairings

Complete your meal with a traditional Vietnamese beverage. A glass of iced jasmine tea or a light beer can complement the flavors of the soup without overpowering them. The subtle floral notes of the tea or the crispness of the beer make for a refreshing finish to your meal.

Make-Ahead Instructions

When it comes to meal prep or planning ahead for a busy week, Vietnamese Winter Melon Soup, or Canh Bí Đao, is wonderfully accommodating. Here’s how we can make this dish ahead of time while preserving its comforting flavors and health benefits.

Preparing the Broth

The foundation of this soup lies in its rich and savory broth. We can prepare the chicken or pork broth a day or two in advance. Simply follow the initial steps of making the broth, let it cool after cooking, and then store it in the refrigerator in an airtight container. This not only saves time on the day of serving but also allows the flavors to deepen, resulting in an even tastier soup.

Preparing the Pork Filling

The pork filling, seasoned with fish sauce and pepper, can also be made ahead. Mix the ground pork with the seasoning, form it into small balls or patties, and then refrigerate it in a sealed container. This make-ahead step allows the pork to marinate, enhancing the flavor profile of the meat.

Cutting the Winter Melon

Winter melon can be prepped in advance as well. Peel and cut the melon into cubes or slices as preferred, then store it in a zip-lock bag or an airtight container in the fridge. This step helps lock in the freshness and reduces prep time on the day of cooking. It’s important, though, to use the pre-cut melon within 24-48 hours to maintain its best texture and flavor.

Assembling and Storing

On the day of serving, all the prepared components come together quickly. Reheat the broth gently, bringing it to a simmer. Add the pre-cut winter melon to the broth and cook until it’s almost tender. Then, drop in the pork balls and continue simmering until fully cooked. Lastly, adjust the seasoning with fish sauce and fresh herbs.

For those ultra busy days, you can even fully cook the soup in advance and store it in portions in the fridge. Reheat gently on the stove or in a microwave, checking the seasoning and adding fresh herbs right before serving. This method ensures that the comforting warmth and subtle sweetness of our beloved Canh Bí Đao are ready to be enjoyed at a moment’s notice, making our lives a little easier and definitely more delicious.

Storage and Reheating Tips

After enjoying the comforting warmth and subtle sweetness of our Vietnamese Winter Melon Soup, Canh Bí Đao, you might find yourself with leftovers. Don’t let them go to waste! Proper storage and reheating are key to maintaining the soup’s delightful flavors and nutritional benefits. Below, we’ll walk you through the best practices for storing and reheating your soup, ensuring every bowl is as satisfying as the first.

Storing Leftover Soup

  1. Cooling Down: Allow the soup to cool to room temperature before storing. This prevents condensation from forming inside the container, which could make the soup watery.
  2. Choosing the Right Containers: Transfer the soup into airtight containers. Glass containers are ideal as they don’t absorb flavors and are easy to clean. However, if you prefer plastic, ensure it’s food-grade and BPA-free.
  3. Refrigerating: Store the soup in the refrigerator if you plan to consume it within the next 3-4 days. The cold temperature slows down bacterial growth, keeping your soup safe and fresh.
  4. Freezing for Longer Storage: For longer storage, pour the soup into freezer-safe bags or containers, leaving some space for expansion. Winter melon soup can be frozen for up to 3 months. When you’re ready to enjoy it, thaw the soup in the refrigerator overnight.


The key to reheating Vietnamese Winter Melon Soup is to do so gently to preserve its flavors and textures.

  1. Refrigerated Soup: Pour the desired amount of soup into a pot and warm it over medium-low heat. Stir occasionally to ensure even heating. Once the soup is steaming hot, but not boiling, it’s ready. Overheating can cause the winter melon to become mushy and the broth to lose its delicate flavors.
  2. Frozen Soup: For frozen soup, it’s best to let it thaw in the refrigerator overnight before reheating. If you’re in a hurry, you can place the frozen soup directly into a pot over low heat. Cover the pot to help trap the heat and speed up the thawing process. Stir occasionally and gently break apart the soup as it softens.


We’ve walked through the delightful journey of making Vietnamese Winter Melon Soup, a dish that’s as comforting as it is nourishing. With the tips and tricks we’ve shared, we’re confident you’ll find it easier to prepare this soup, making it a perfect addition to your winter menu. Remember, the key to a delicious Canh Bí Đao lies in the preparation of its components and the final assembly. Don’t forget to adjust the seasoning to your taste and enjoy the warmth it brings to your table. Here’s to many cozy meals ahead!
