Some soups don’t ask for much. They don’t need fancy toppings or a long list of spices. They just need a pot, a little time, and whatever good things you already have on hand. This Mustard Green Soup with Roasted Meat is that kind of soup. It’s a quiet Cambodian home dish made with leftover roasted pork, duck, or chicken, simmered with tender mustard greens in a light, savory broth.

The roasted meat does most of the heavy lifting here, giving the broth a deep, gentle flavor without any extra work. Mustard greens soften into the liquid and bring a mild peppery bite that keeps every spoonful interesting. It’s the kind of soup you make when you want something warm and unfussy that still tastes like it took effort.

What You Need

You only need a handful of ingredients for this soup, and most of them are pantry staples. The key players are leftover roasted meat and fresh mustard greens. Use whatever roasted meat you have — pork, duck, chicken, or a mix of all three works beautifully. The broth is built from chicken broth and water, seasoned simply with fish sauce, sugar, and black pepper. Green onions go on top at the end for a fresh finish.

Equipment

Soup pot: To simmer the broth, roasted meat, and mustard greens together.

Chef’s knife: To cut the mustard greens into 2-inch lengths and chop the green onions.

Cutting board: To safely prepare the mustard greens and green onions.

Measuring cups: To measure the chicken broth and water.

Measuring spoons: To measure the fish sauce, sugar, and black pepper.

Wooden spoon or cooking spoon: To stir the soup as it cooks.

Ladle: To transfer the finished soup and broth into serving bowls.

Serving bowls: To serve the hot soup with rice.

How to Make Mustard Green Soup with Roasted Meat

Step 1: Build the broth base

Pour the chicken broth and water into a soup pot. Add the leftover roasted meat. Place the pot over medium-high heat and bring the liquid to a bubbling boil. The roasted meat will start to release its flavor into the broth as it heats through.

Step 2: Add the mustard greens

Once the broth is bubbling, add the mustard greens. Give everything a good stir. Let the soup come back to a bubbling boil. The greens will wilt and soften into the broth.

Step 3: Season the soup

Season with fish sauce, sugar, and black pepper. Stir well and taste. The fish sauce brings saltiness and depth, the sugar rounds out the edges, and the black pepper adds a gentle warmth.

Step 4: Finish and serve

Top with chopped green onions. Ladle the hot soup into bowls and serve with steamed rice.

Cooking Tips

Use whatever roasted meat you have. This soup is designed for leftovers. Roasted pork, duck, chicken, or a combination all work well. The meat is already cooked, so it just needs to heat through and flavor the broth.
Don’t overcook the mustard greens. They only need a few minutes in the boiling broth to soften. They should still have a little texture, not turn mushy.
Taste before serving. Fish sauce brands vary in saltiness. Start with the amount listed, then adjust if needed.

How to Serve

Serve this soup hot with steamed jasmine rice. The rice soaks up the savory broth, and the mild bitterness of the mustard greens pairs nicely with the rich roasted meat. It’s a complete, comforting meal in one bowl.

Frequently Asked Questions

What kind of roasted meat works best for this soup?

Any leftover roasted meat works — roasted pork, duck, chicken, or a mix. The meat is already cooked, so it mainly adds flavor to the broth and heats through.

Can I use fresh mustard greens instead of another type of green?

This recipe calls for mustard greens specifically. They have a mild peppery flavor that works well with the roasted meat. If you can’t find them, you could try another sturdy green, but the taste will be different.

How should I store leftovers?

Store leftover soup in an airtight container in the refrigerator. According to USDA food safety guidance, most cooked leftovers remain safe for 3 to 4 days when properly refrigerated.

Is this soup gluten-free?

Fish sauce is typically gluten-free, but brands vary. Check the label of your fish sauce to confirm. The other ingredients — chicken broth, water, roasted meat, mustard greens, sugar, black pepper, and green onions — are naturally gluten-free.

Can I make this soup ahead of time?

Yes. The soup reheats well. Make it a day ahead and store it in the refrigerator. Reheat gently on the stovetop, adding a splash of water if the broth has thickened.

What does mustard green soup taste like?

The broth is light and savory, with a gentle richness from the roasted meat. Mustard greens add a soft, mild peppery note. It’s not spicy — just warm, comforting, and clean-tasting.
