5.0 from 3 votes

Winter melon gourd and steamed mackerel soup is a quiet, comforting Cambodian dish. The gourd turns soft and almost translucent in a light broth, while salty steamed mackerel gives each spoonful a deep savory note.

It is the kind of soup that feels gentle but satisfying, especially with hot rice. This version keeps things simple: pan-fry the mackerel with garlic, simmer the melon until tender, and finish the pot with fish sauce, a little sugar, and black pepper.

What You Need

The recipe uses a whole winter melon gourd, salty steamed mackerel, and a short list of pantry seasonings. Winter melon is a mild, watery gourd that absorbs the broth without falling apart. Salty steamed mackerel is already seasoned, so taste the soup before adding extra salt. A little sugar and black pepper round out the flavor. If you want to serve rice on the side, start cooking it before you begin the soup.

How to Make Winter Melon Gourd and Steamed Mackerel Soup

Step 1: Prepare the Mackerel (Optional)

If you want boneless fish, clean the mackerel and remove the heads and guts. Make a shallow butterfly cut along the belly, then gently pull out the central bones without breaking the fish shape. Set the fish aside. If you prefer, you can skip this step and remove bones at the table.

Step 2: Fry the Garlic and Mackerel

Heat a skillet or wok over medium heat. Add the vegetable oil and chopped garlic. Stir until the garlic turns golden brown but not burned. Remove the toasted garlic from the oil and set it aside. Add the steamed mackerel to the hot oil and pan-fry until it is lightly browned on both sides. Set the fish aside.

Step 3: Simmer the Winter Melon

Put the winter melon chunks and water (or chicken broth) into a soup pot. Cook over medium heat until the winter melon is almost tender. It should soften enough that a spoon can pierce it easily, but it should still hold its shape.

Step 4: Add the Fish and Season

Add the fried mackerel to the pot. Continue cooking until the winter melon is fully tender. Season with fish sauce, salt, sugar, and black pepper. Stir gently so the fish does not break apart. Taste the broth and adjust if needed—salty mackerel brands vary.

Step 5: Finish and Serve

Turn off the heat and scatter the chopped green onion over the top. If you kept the toasted garlic, you can add it as a garnish. Ladle the soup into bowls and serve hot.

Cooking Tips

Start with the lower amount of fish sauce and salt. The steamed mackerel is already salty, and the soup will taste different depending on the brand. You can always add more seasoning at the end.

Keep the winter melon pieces similar in size so they cook evenly. Gentle simmering is better than a hard boil once the fish is in the pot, because it helps the mackerel stay intact.

When you handle the mackerel, keep it refrigerated and use it within 1 to 2 days of purchase. For safe handling and storage reminders, see the FDA guidance on selecting and serving seafood safely.

How to Serve

Ladle the soup into bowls and serve it hot with steamed jasmine rice. The rice soaks up the savory broth and makes the meal more filling. A simple cucumber or tomato salad on the side adds a fresh contrast.

Recipe Notes

Deboning the mackerel is optional. Leaving the bones in is fine if you prefer to remove them while eating. The recipe uses 2 to 3 pounds of winter melon, which gives a flexible pot: a smaller gourd makes a thicker soup, and a larger gourd makes a lighter, more broth-forward soup.

Because the mackerel is salty, taste the broth after the fish has simmered for a few minutes before adding extra salt or fish sauce.

Frequently Asked Questions

Can I use fresh mackerel instead of salty steamed mackerel?

The supplied recipe is built around salty steamed mackerel, which is already seasoned and firm. Fresh mackerel would change the salt level and the texture of the soup, so it is not a direct swap in this version.

How should I store leftovers?

Cool the soup and refrigerate it within 2 hours. Store it in a shallow container for 3 to 4 days. Reheat gently on the stovetop until steaming hot. For more detail, follow the USDA FSIS leftovers guidance.

Is this soup gluten-free?

The main ingredients are naturally gluten-free, but fish sauce brands can differ. Check the label on your fish sauce if you need a confirmed gluten-free dish.

Final Thoughts

Winter melon gourd and steamed mackerel soup is a simple bowl with a deep savory edge. The gourd softens into the broth, and the pan-fried mackerel gives it enough richness to stand on its own. Serve it hot with rice and let the quiet flavors do the work.
