Ingredients You’ll Need

For a recipe this rich and flavorful, each ingredient plays a pivotal role. From the pork bones forming a robust broth base to the lemongrass and spices injecting fragrant warmth, these ingredients blend beautifully to create that amazing Bun Bo Hue experience. When you shop, look for fresh aromatics and quality beef cuts to bring out the best taste.

• Pork bones: Essential for making a rich, flavorful broth; get meaty bones for the best depth.
• Brisket: Adds tender beef flavor and substance to the soup.
• White onion: Adds subtle sweetness and helps clarify the broth when roasted.
• Ginger: Adds warmth and balances the spices; fresh slices work best.
• Lemongrass: The unmistakable citrusy note; smack or smash to release its oils.
• Garlic: Used both in the broth and oil mixture for aromatic depth.
• Cinnamon stick: Adds subtle sweetness and complexity.
• Whole cloves: A little goes a long way in perfume and flavor.
• Pure sesame oil: Adds nutty richness in both the oil mixture and seasoning.
• Annatto seeds: Infuse a beautiful color and subtle flavor to the oil.
• Shallots: Minced for oil mixture to boost the aroma.
• Red pepper flakes: You control the heat here—adjust to taste.
• Shrimp paste: The secret umami booster for authentic flavor; look for a good quality one.
• Chicken bouillon: Enhances the broth’s savory depth.
• Kosher salt: Balances and seasons all elements.
• Fish sauce: A crucial savory backbone, adding the quintessential Vietnamese touch.
• Beef tenderloin: Thinly sliced for cooking quickly in the hot broth.
• Hue noodles: Thicker round rice noodles typical for this soup; you can find them at Asian markets.
• Vegetables: Water spinach, banana flower, bean sprouts, fresh oregano, lime wedges, and optional shredded red cabbage for freshness and texture.
• Side sauce: Fish sauce mixed with Thai chilies and shrimp paste for extra heat and seasoning at the table.

Variations

I love making this recipe my own by tweaking the spice and toppings based on the season or what I have on hand. Don’t hesitate to experiment — that’s part of the fun! This soup is forgiving and allows for some great personalization.

• Spice level: When I want a milder soup, I reduce red pepper flakes and skip the spicy side sauce; for a fiery kick, I add extra Thai chilies.
• Protein swaps: Sometimes I add pork shank or beef shank for a different texture, giving the broth some extra gelatinous goodness.
• Vegetarian version: I’ve tried making a mushroom and tofu-based broth with lots of lemongrass and spices as a substitute, which works well if you skip the shrimp paste.
• Seasonal veggies: Depending on what’s fresh at the market, I’ll swap out water spinach for bok choy or add fresh herbs like Thai basil for a vibrancy boost.

How to Make Authentic Bun Bo Hue – Spicy Beef Noodle Soup Recipe

Step 1: Building the Broth Base

Start by blanching the pork bones in boiling water for about 10 minutes to remove impurities, which keeps your broth clear and clean-tasting. Then rinse the bones and brisket under cold water before adding them to a large pot with 7 quarts of fresh water. Toss in the whole white onion, ginger slices, smashed lemongrass, garlic cloves, cinnamon stick, and cloves. Let this simmer gently for at least 3 hours—patience here is key. A slow simmer extracts incredible depth without clouding the broth. Skim off any foam that rises to keep it clear and flavorful.

Step 2: Making the Oil Mixture

While your broth simmers, prepare the oil mixture that will give the soup its vibrant hue and aroma. Heat pure sesame oil in a small pan and add the annatto seeds, cooking until the oil turns a gorgeous red-orange color (don’t burn the seeds!). Strain out the seeds, then return the oil to the pan to sauté minced shallots and garlic until golden and fragrant. This step adds a smoky, sweet depth you won’t want to skip.

Step 3: Seasoning the Broth

Once the broth’s been simmering and the brisket is tender, remove the meat and set aside to cool before slicing thinly. Add the oil mixture and combine the seasoning mix: pure sesame oil, red pepper flakes, minced lemongrass, shrimp paste, chicken bouillon, kosher salt, and fish sauce. Stir carefully, and let the broth continue to simmer gently for at least another 30 minutes so the flavors mingle beautifully. Taste frequently and adjust salt or spiciness to your liking—it’s your bowl of awesome, after all!

Step 4: Preparing Noodles and Meat

While the broth finishes, soak or cook the Hue noodles per package instructions so they’re tender but still have a bit of bite. Slice the beef tenderloin very thin—this will cook perfectly when ladled over the hot broth later. Similarly, thinly slice the cooled brisket you set aside earlier. This layering of beef textures gives the soup extra richness and mouthfeel.

Step 5: Serving Your Bun Bo Hue

At last, assemble your bowl! Place a portion of noodles into a bowl, top with sliced brisket and tenderloin, then ladle the steaming hot broth over it. Add thinly sliced white onion and chopped green onions for freshness. Now, gather your veggies and herbs for the finishing touches.

Garnishes

I always keep fresh banana flower, water spinach, bean sprouts, and oregano on the side. The lime wedges are a must for brightening up the broth, and if you’re feeling adventurous, shredded red cabbage adds a lovely crunch and color contrast. Don’t forget the side sauce—fish sauce with sliced Thai chilies and shrimp paste—which packs an extra punch for those who like their soup extra spicy and savory.

Side Dishes

I like pairing this spicy noodle soup with simple Vietnamese spring rolls or a crisp green papaya salad. If you have some Vietnamese iced coffee to sip alongside, you’re officially living the experience. These sides offer refreshing textures and flavors that balance the soup’s heat perfectly.

Creative Ways to Present

For special occasions, I’ve served Bun Bo Hue in individual bowls with edible flower petals and fresh herbs artistically arranged on top—your guests love the visual appeal! Another idea is offering a “build-your-own” noodle bar where people customize toppings and spice levels, making it a fun and interactive meal.

Make Ahead and Storage

Storing Leftovers

I usually store leftover broth and meat separately in airtight containers in the fridge for up to 3 days. Keeping noodles apart helps prevent them from getting mushy. When you’re ready to eat again, warm the broth slowly and add fresh noodles and veggies—you’ll get almost that fresh-cooked feeling all over again.

Freezing

If you want to freeze, pour the broth and meat into freezer-safe containers but hold off on freezing veggies or noodles—they don’t reheat well. Keep frozen for up to 2 months. When thawed, just boil the broth and add fresh noodles and garnishes.

Reheating

Reheat the broth gently on the stove, stirring occasionally to keep the flavors vibrant. Add beef slices briefly to warm through without overcooking, then drop in freshly cooked noodles and your preferred veggies. Quick and delicious—just like the first time!
