Burmese Fish Noodle Soup

A deeply comforting, golden Burmese fish noodle soup (Mohinga) featuring a lemongrass-infused broth, toasted rice powder, and tender rice noodles.

Why This Recipe Works:

• Toasted rice powder acts as a natural thickener, creating a velvety body through starch gelatinization.
• Searing the aromatics in oil first coaxes out oil-soluble flavor compounds from the lemongrass and turmeric.
• Flaking the fish back into the broth ensures every single spoonful is packed with savory texture and protein.

The first time I boiled catfish in my drafty third-floor apartment, the steam coated my windows in a greasy film. I stood over the stove, tapping the wooden spoon against my hip, watching the muddy water bubble. It took three rounds of hot vinegar to finally scrub that stubborn scent out of the drywall.

I was chasing the memory of a golden, lemongrass-scented bowl from a Queens street market. My first attempt tasted flat and metallic.

I failed miserably.

The problem lies in how we treat the fish and the aromatics on a molecular level. Most recipes treat this like a quick and spicy shrimp soup by boiling everything rapidly, which completely ignores how oil-soluble flavor compounds in lemongrass actually behave. Without a proper fat medium to extract those essential oils, you end up with a watery broth that tastes like boiled pond water instead of a cohesive, velvety soup.

The secret is a two-step approach. We toast rice powder to create a starch gelatinization matrix that suspends the fish oils beautifully.

Then, we fry our aromatics in oil first to unlock their deep, savory potential. This technique transforms a simple seafood broth into something as rich and comforting as a slow-simmered chicken noodle soup with ginger and scallions or a cozy ginger garlic bok choy soup.

Ingredients

• 1 lb catfish fillets (or cod)
• 4 cups water
• 2 tbsp fish sauce
• 1 tsp ground turmeric
• 3 tbsp toasted rice powder
• 2 tbsp chickpea flour
• 3 tbsp neutral oil
• 2 stalks lemongrass, white parts bruised and finely minced
• 1 medium red onion, sliced
• 4 cloves garlic, minced
• 1 inch fresh ginger, grated
• 1 tsp Diamond Crystal kosher salt
• 14 oz dried round rice noodles
• Hard-boiled eggs, cilantro, lime wedges, and chili flakes for serving

Directions

1. In a medium pot, combine the fish fillets, water, fish sauce, and turmeric. Bring to a gentle simmer and cook for 8-10 minutes until the fish flakes easily.
2. Fish out the cooked fillets with a slotted spoon, letting them cool slightly on a plate. Keep the poaching liquid in the pot—this is your golden broth base. Flake the fish into bite-sized pieces, discarding any bones.
3. In a small bowl, whisk the toasted rice powder and chickpea flour with 1/2 cup of cold water until a smooth slurry forms. Whisk this slurry directly into the warm poaching liquid.
4. Heat the neutral oil in a large skillet over medium heat. Add the minced lemongrass, sliced onion, garlic, and ginger. Cook for 5-7 minutes until soft and fragrant, but do not let them burn.
5. Pour the sautéed aromatic mixture and the flaked fish back into the main pot with the broth. Bring to a gentle boil, then reduce heat to low and simmer for 20 minutes, stirring occasionally to prevent the rice powder from sticking to the bottom.
6. While the soup simmers, cook the rice noodles according to package instructions and drain. Divide the noodles among bowls, ladle the hot golden fish broth over them, and garnish with hard-boiled egg slices, fresh cilantro, a squeeze of lime, and chili flakes.

Notes

• Always use Diamond Crystal kosher salt; if you are using Morton's or fine table salt, cut the volume by half to avoid an over-salted broth.
• Toasted rice powder is non-negotiable. The heat-treated starches undergo gelatinization when whisked into the hot broth, which suspends the fish oils and prevents the soup from separating into water and solids.
• Keep a close eye on your lemongrass and garlic paste when frying. If they burn, the bitter compounds will ruin the delicate sweetness of the fish broth, so keep your heat at medium-low and stir constantly.
• Rice noodles act like sponges. If you store them directly in the broth, they will absorb all the liquid overnight and turn into mush. Always store the broth and noodles in separate airtight containers in the fridge.

Serving Suggestions

Complete your Burmese feast by setting out a spread of vibrant toppings. Let everyone customize their bowl to balance the rich, savory broth with bright, crunchy textures.

• Crispy split pea fritters (bayar kyaw) for a traditional crunch
• Fresh cilantro leaves and chopped scallions for a burst of herbal brightness
• Hard-boiled egg slices to add a creamy, rich element to each spoonful
• Lime wedges to cut through the deep, savory fish flavors
• Roasted chili flakes or chili oil for those who crave a fiery kick
• A side of crispy grilled zucchini to add a charred, smoky vegetable element to the table

Storage and Reheating

This broth actually tastes significantly better the next day once the lemongrass and fish flavors have had time to marry in the fridge. Store the strained golden broth in a glass jar for up to three days.

Reheat it gently on the stovetop over medium-low heat. Avoid boiling it rapidly, as this can break the starch emulsion and make the soup look cloudy.

Never freeze the noodles.

Cooked rice noodles lose their structural integrity in the freezer. If you want to prep this ahead, freeze only the broth base, then boil fresh noodles right before you plan to serve.

Ingredient Substitutes

If you can't find some of the traditional ingredients, don't panic. Here are the best swaps to keep the soul of the dish intact:

1. Catfish: Swap with cod, halibut, or tilapia. Avoid oily fish like salmon.
2. Toasted Rice Powder: You can toast raw jasmine rice in a dry skillet until golden, then grind it in a spice grinder. If unavailable, use toasted glutinous rice powder.
3. Chickpea Flour: Yellow split pea flour works beautifully as a direct 1:1 substitute.
4. Lemongrass: While fresh is best, frozen minced lemongrass works in a pinch. Avoid dried lemongrass stalks as they lack the essential oils needed for the broth.

Grab your biggest bowl, ladle in that steaming golden broth, and don't be shy with the lime wedges. It might take a little patience to get the starch emulsion just right, but once you take that first slurp, your kitchen will feel like the coziest place on earth.
