Step‑by‑Step Instructions for Spicy Beef Noodle Soup

Step 1: Prepare the Broth
In a large pot, bring 7 quarts of filtered water to a rolling boil. Add the pork bones and let them boil for 10 minutes to remove impurities, then drain and rinse the bones thoroughly. Blanch the brisket in the same pot, afterward rinsing it as well. This will create a clean, flavorful base for your Authentic Bun Bo Hue. Toast the cinnamon stick, whole cloves, and ginger in a separate pan until aromatic.

Step 2: Add Ingredients to the Broth
Return the cleaned pork bones and brisket to the pot with boiling water. Add the toasted spices along with the smashed lemongrass stalks. Bring the mixture back to a boil, then lower the heat and let it simmer. Skim the surface for impurities occasionally, ensuring your broth is clear. Simmer for 45 minutes, then add the whole white onion and continue simmering for another 45 minutes for deep flavors.

Step 3: Make the Oil and Seasoning Mixture
While the broth simmers, heat pure sesame oil in a small pan over medium heat. Add annatto seeds and minced garlic, infusing the oil for about 3-5 minutes until fragrant and vibrant. Strain the mixture to separate the seeds from the oil. In the same pan, sauté the shallots until golden, then combine with the infused oil and seasoning ingredients to enhance your broth’s complexity.

Step 4: Finish the Broth
Once your simmering time has elapsed, discard the solid aromatics from the broth, ensuring a clean finish. Stir in the oil mixture along with 8 cups of hot water back into the pot. Add chicken bouillon, kosher salt, and fish sauce to taste. Continue simmering for an additional 20 minutes, allowing those rich flavors from the spices and ingredients to meld beautifully in your Authentic Bun Bo Hue.

Step 5: Prepare for Serving
As the broth finishes, slice the cooked brisket and quickly blanch the tenderloin slices in the broth to keep them warm. Meanwhile, cook the Hue noodles according to the package instructions until they are tender yet chewy. Drain and keep the noodles warm, setting the stage for your delicious and hearty spicy beef noodle soup.

Step 6: Assemble the Dish
In each bowl, add a hearty serving of the warm Hue noodles. Layer on the sliced brisket and tenderloin, then ladle the aromatic broth over the noodles. For a delightful presentation, garnish with thin slices of onion, chopped green onions, and your choice of fresh vegetables. Serve your Authentic Bun Bo Hue hot, accompanied by lime wedges and the dipping sauce for an unforgettable meal.

Tips for the Best Spicy Beef Noodle Soup

Broth Clarity: Ensure clear broth by not stirring during simmering. Skim any impurities that rise to the surface gently.
Room Temperature Ingredients: Allow both the pork bones and brisket to rest at room temperature before boiling to maintain broth clarity.
Spice Balance: Adjust seasoning, especially fish sauce and shrimp paste, to enhance the flavor of your spicy beef noodle soup according to your taste preferences.
Precise Cooking: Avoid modern appliances like Instant Pots to retain the authentic texture and flavors of this traditional dish.
Fresh Garnishes: Don’t skip on fresh vegetables like bean sprouts and lime wedges; they provide a fresh contrast to the hearty broth.

Authentic Bun Bo Hue Recipe FAQs

What type of pork bones should I use for the broth?
Absolutely! For the richest and most flavorful broth, I recommend using meaty pork bones, such as neck bones or a mix of marrow and rib bones. These contain enough collagen to create a velvety texture, enhancing the overall quality of your Authentic Bun Bo Hue.

How should I store my leftover Bun Bo Hue?
To keep your spicy beef noodle soup fresh, store it in an airtight container in the refrigerator for up to 3 days. Allow the broth to cool completely before sealing it to maintain its flavors and prevent spoilage.

Can I freeze Bun Bo Hue, and if so, how?
Yes, of course! To freeze your spicy beef noodle soup, first, divide it into portions. Store the broth and noodles separately in airtight containers; the broth can be frozen for up to 3 months, while noodles should be consumed within 2 months for best texture. When you’re ready to enjoy, just thaw the broth in the fridge overnight, reheat gently, and cook fresh noodles to mix in prior to serving.

What if my broth isn’t clear?
Very good question! If your broth turns cloudy, it’s usually due to stirring or not skimming impurities. To achieve a clear broth, make sure to skim any foam or impurities that rise to the surface during simmering. Additionally, avoid stirring the pot as it can reintroduce sediment to the broth.

Is there any dietary consideration for this recipe?
Indeed! If you’re cooking for someone with shellfish allergies, I recommend omitting the shrimp paste. You can replace it with additional fish sauce for umami depth without compromising flavor. Always check for dietary restrictions of your guests to personalize this hearty meal effectively!
