What Is Bun Ga Nuong?

Bun ga nuong (bún gà nướng) is a Vietnamese rice vermicelli bowl topped with lemongrass-marinated grilled chicken, fresh vegetables and herbs, and a sweet-tangy fish sauce dressing called nước chấm. The bowl typically includes cool rice noodles, sliced grilled chicken, lettuce, cucumber, mint, pickled daikon and carrot known as đồ chua, crushed roasted peanuts, and a spoonful of scallion oil, or mỡ hành. Everything is assembled in one bowl, dressed with nước chấm, and mixed together just before eating.

English speakers can pronounce bún gà nướng approximately as “boon gah noo-ung.” The words gà nướng simply mean “grilled chicken.”

In this version, chicken takes the place of the pork more commonly associated with bún thịt nướng, while the southern Vietnamese bowl structure remains the same: rice vermicelli, greens, đồ chua, mỡ hành, peanuts, and a light fish sauce dressing assembled together. This differs from Hanoi-style bún chả, in which the noodles, herbs, grilled meat, and dipping sauce are usually served as separate components.

You will spot it on American menus under the "vermicelli bowl" or "bun" section. This is where a lemongrass-citrus marinade meets a savory-sweet fish sauce dressing, crunchy pickled vegetables, and the herbal lift of fresh mint and lettuce.

Grilled lemongrass chicken, vermicelli, herbs, and fish sauce create a balanced Vietnamese noodle bowl. 

Why You'll Love Bun Ga Nuong

You'll love this bun ga nuong because the lemongrass marinade does all the heavy lifting, and every bite gives you a mix of smoky chicken, tangy pickles, crunchy peanuts, and fresh herbs.

• You can easily change up the flavor. The lemongrass marinade brings out a great mix of citrus, garlic, and sweet, caramelized flavors in the chicken, while the fish sauce dressing brings all the fresh, crunchy, and smoky elements together. Feel free to add as much chili as you like.
• It works perfectly for 1 person or a whole crowd. You can whip it up for a quick weeknight dinner, or just set out the noodles, chicken, herbs, and toppings so everyone can build their own bowl.
• It takes only 30 minutes of active cooking. The marinade takes care of the flavor while you get everything else ready, so the whole bowl comes together without any special tools.

Bun Ga Nuong Ingredients

This bun ga nuong comes together from 5 main parts: the chicken and marinade, the pickled veggies, the dipping sauce, the scallion oil, and the noodles with herbs. This recipe uses 18 ingredients in total and serves 4 people.

Chicken and Marinade

• 1.75 to 2 lb (800 to 900 g) boneless chicken thighs or breasts, with the skin and bones removed. We prefer thighs over breasts here because thighs stay super juicy during high-heat cooking and handle the marinade well without drying out. Breasts work fine too, but keep a close eye on the cooking time so they do not get dry and chalky.
• 1 tbsp fish sauce (nước mắm), preferably 30 to 40°N. The °N rating reflects the sauce’s total nitrogen content, which contributes to its depth and savory flavor rather than directly indicating saltiness. Since both flavor intensity and salt levels vary by brand, adjust to taste if needed.
• 1 tbsp oyster sauce.
• 1 tbsp Vietnamese caramel sauce (nước màu). If unavailable, dark soy sauce can provide color, but it will add soy flavor and extra salt.
• 1 tbsp scallion oil.
• 1 tbsp sugar.
• 1 tbsp honey.
• ½ tbsp lime juice.
• 2 stalks of lemongrass, bruised and sliced. Smash the stalks with the back of your knife before slicing them, because crushing them breaks the fibers and releases the aromatic oils inside. This helps the marinade soak up a much stronger lemongrass flavor in less time.
• 2 to 3 cloves of garlic, minced.

Pickled Vegetables (Đồ Chua)

1 medium daikon radish, 1 small carrot, 1 tsp salt, ⅓ cup warm water, ⅓ cup rice vinegar, and 3 tbsp sugar.

Dipping Sauce (Nước Chấm)

Fish sauce, sugar, lime juice, and water, mixed at a 1:1:1:5 ratio, plus some minced garlic and sliced chili.

Scallion Oil (Mỡ Hành)

3 to 4 scallions, washed and sliced, plus 1 to 2 tbsp of cooking oil and a pinch of salt.

Noodles and Herbs

• 2.2 lb (1 kg) fresh rice vermicelli (bún tươi). We love using fresh rice vermicelli because it is softer, silkier, and just like what you get at a real Vietnamese restaurant. You can usually find fresh vermicelli in the fridge section at most Asian grocery stores in the US. If you cannot find it, dried rice vermicelli (bún khô) cooked according to the package instructions works as a backup, even though it turns out a little firmer.
• Fresh veggies and herbs: some lettuce, cucumber, bean sprouts, and fresh herbs, adjusted to your own taste.
• Roasted peanuts, crushed up for a nice crunch.

Based on typical US grocery prices, the amount of ingredients used costs about $30 to $35 in total, or roughly $7.50 to $8.75 per serving. The upfront grocery bill may be higher if you need to buy full bottles and packages of pantry staples such as fish sauce, oyster sauce, vinegar, sugar, and cooking oil. 

How to Make Bun Ga Nuong Step by Step

Making bun ga nuong takes about 1 hour and 30 minutes from start to finish, including marinating time. The recipe has 8 simple steps, with around 30 minutes of preparation and cooking time.

Step 1: Prep the Chicken

Remove the chicken from its packaging and pat it dry with paper towels. Trim off any excess fat if needed, then place it in a clean bowl for marinating.

Do not rinse raw chicken, as splashing water can spread bacteria to nearby surfaces. Wash your hands and clean any utensils or surfaces that touched the chicken.

Step 2: Marinate the Chicken

In a large bowl, mix the chicken with all the marinade ingredients: fish sauce, oyster sauce, caramel sauce, scallion oil, sugar, honey, lime juice, smashed lemongrass, and garlic. Cover it and refrigerate for at least 1 hour, or overnight for a deeper flavor. Keep it under 24 hours max, because anything longer will ruin the texture of the meat.

Step 3: Make the Pickled Vegetables

Cut 1 medium daikon and 1 small carrot into thin strips. Toss them with 1 tsp salt and let them sit for 10 minutes, then rinse well and squeeze out the excess water.

In a bowl, stir together ⅓ cup warm water, ⅓ cup rice vinegar, and 3 tbsp sugar until the sugar dissolves. Add the daikon and carrot, then refrigerate for at least 15 minutes while the chicken marinates. Drain before serving.

Step 4: Make the Dipping Sauce

Mix 3 tbsp fish sauce (30 to 40°N), 3 tbsp lime juice, 3 tbsp sugar, and 15 tbsp water in a bowl using a simple 1:1:1:5 ratio. Stir it well until all the sugar dissolves, then toss in the minced garlic and sliced chili so they float right on top.

For an easy-to-balance nước chấm, use a fish sauce with a rounded aroma and enough savory intensity to remain noticeable after dilution. A 30 to 40°N fish sauce works well here; the °N value refers to total nitrogen, not saltiness. CHIN-SU fish sauce can be used for this recipe, then adjusted with water, lime juice, or sugar to taste.

Step 5: Make the Scallion Oil

Wash and finely chop 3 to 4 scallions, then add a pinch of salt. Pour 1 to 2 tbsp of hot neutral oil over the scallions and stir briefly. The oil should soften them and release their aroma without browning. Mỡ means “fat,” but modern mỡ hành is often made with vegetable oil. You can also mix the scallions, salt, and oil in a microwave-safe bowl and heat for about 20 seconds.

Step 6: Cook the Chicken

Preheat a skillet over medium to medium-high heat and add a thin layer of oil. Remove the chicken from the marinade and brush off any loose pieces of lemongrass and garlic, as they can burn quickly and turn bitter.

Pan-sear the chicken, turning as needed, until both sides are golden brown and the thickest part reaches 165°F (74°C). Because the marinade contains sugar, honey, and Vietnamese caramel sauce, reduce the heat if the surface darkens before the chicken is cooked through. The nước màu helps give the chicken its amber glaze and subtle bittersweet depth. Transfer the chicken to a clean plate, let it rest briefly, then slice.

The chicken can also be cooked using one of these methods:

• Oven: Bake at 375°F (190°C) for about 20 minutes. Broil for 1 to 2 minutes at the end if more color is needed.
• Air fryer: Cook at 380°F (193°C), flipping halfway through and checking for doneness after about 8 minutes.
• Charcoal grill: Grill over medium-high heat, turning as needed and checking for doneness after about 6 to 8 minutes.

Cooking time will vary depending on the thickness of the chicken, its starting temperature, and the appliance. Use these times as starting points and always confirm that the thickest part reaches 165°F (74°C).

Step 7: Prepare the Noodles

If the fresh bún is ready to eat, gently separate the strands and divide them among the bowls. Briefly blanch it only when required by the package instructions. For dried rice vermicelli, cook according to the package directions, rinse briefly under cool running water, and drain thoroughly.

Step 8: Prep the Herbs and Vegetables

Rinse the lettuce, cucumber, bean sprouts, and herbs thoroughly under cool running water, then drain and dry them well. Slice the cucumber into thin strips. Leave the bean sprouts raw for more crunch, or blanch them briefly for a softer texture. Crush the roasted peanuts and set them aside for topping.

How to Serve Bun Ga Nuong

Bun ga nuong is a simple one-bowl meal where you just pile everything together, pour the sauce on top, and mix it all up right before you take a bite. To build your bowl, just layer everything from the bottom up. The classic setup goes like this:

• Rice vermicelli, either fresh or dried, works as your base.
• Sliced grilled lemongrass chicken, added while it is still warm, right out of the pan.
• Lettuce, cucumber, and fresh herbs to give it a cool, crisp layer.
• Pickled daikon and carrot bring in a nice tangy flavor.
• Crushed roasted peanuts and a spoonful of scallion oil dropped right on top.
• Nước chấm served alongside or poured over the bowl just before eating.

For family-style serving, give each person an individual bowl and place the herbs, toppings, and nước chấm in shared dishes at the center of the table. For a larger meal or backyard cookout, set out all the components separately so everyone can build their own bowl.

Serve the noodles, vegetables, and herbs cool or at room temperature, with the chicken added while it is still warm. Add the nước chấm gradually, mix from the bottom so it reaches the noodles and vegetables, then taste before adding more.

For a more convenient option, use CHIN-SU Sweet and Sour Dipping Fish Sauce as a ready-made nước chấm. 

Tips for the Best Bun Ga Nuong

These 5 small choices make all the difference between good bun ga nuong and great bun ga nuong.

• Marinate overnight if you can. 1 hour works fine, but an overnight rest lets the fish sauce and lemongrass season the chicken all the way through. Keep it under 24 hours max, since the acid starts breaking down the texture after that.
• Brush off the lemongrass before cooking. The small bits burn super fast in a hot pan and turn bitter, so leave only what naturally sticks to the meat.
• Get the pan screaming hot before the chicken goes in. High heat gives you that perfect caramelized sear and a grilled look even without a grill. If the pan smokes too much, turn down the heat slightly and add a splash of water.
• Prep the pickled vegetables and dipping sauce first. Both taste much better after spending a little time in the fridge, and making them while the chicken marinates keeps your actual hands-on cooking under 30 minutes.
• Use fresh vermicelli if you can find it. Fresh rice vermicelli has a softer, chewier texture than dried vermicelli, and you can easily find it in the refrigerated section at Asian grocery stores. Dried rice vermicelli works well as a backup for US kitchens.

What Can You Substitute or Change in Bun Ga Nuong?

These substitutions help you make bun ga nuong with regular US grocery store ingredients without losing the dish's core flavor.

Ingredient swaps

• Lemongrass paste or frozen minced lemongrass replaces fresh lemongrass. You can use about 1 tablespoon of paste instead. The aroma turns out a bit milder, but the citrus note still carries through, and you can easily find both options at Asian grocery stores.
• Dried rice vermicelli replaces fresh. Dried noodles lose the soft chew of fresh ones, though they are widely available at any Asian market or regular supermarket. Just cook them according to the package instructions.
• Chicken breast replaces chicken thigh. Chicken breasts dry out much faster, so you need to watch the cooking time closely.
• Mint or Thai basil replaces perilla (tía tô) or Vietnamese balm (kinh giới). You might lose the peppery bite of perilla, but the herb plate still works great, so just treat these as optional if the originals are hard to find.
• Homemade Vietnamese caramel sauce is the closest substitute for bottled nước màu. Dark soy sauce can provide color in a pinch, but it adds soy flavor and extra salt, so it should not be treated as an equal replacement.

Cooking method swaps

• An oven, air fryer, or charcoal grill replaces the pan-sear. You can bake the chicken at 375°F (190°C) for 20 minutes, air-fry it at 380°F (193°C) for 8 minutes, flipping it halfway through, or grill it over charcoal for 6 to 8 minutes total. The pan-sear gives you a nice caramelized crust, the grill brings out a smoky char, and the oven is the easiest hands-off option.

You can change things up as often as you need to. Still, the closer you stay to the original ingredients, the closer you get to that authentic Vietnamese flavor.

How to Store Bun Ga Nuong

Bun ga nuong is best eaten fresh, but leftovers can be stored by keeping each component in a separate airtight container. Assembling the bowls ahead of time can make the noodles soggy and cause the herbs to wilt.

Keep the cooked chicken in the fridge for up to 3 to 4 days and reheat it gently before serving. Store the noodles for up to 3 days, then microwave them under a damp paper towel until softened and let them cool before assembling the bowl.

Fresh herbs are more delicate and are best used within 2 to 3 days. Lettuce, cucumber, and bean sprouts should also be stored separately and used while they are still crisp. The pickled vegetables and nước chấm keep longer than the fresh produce when sealed and refrigerated.

Assemble each bowl only when you are ready to eat.
