Spicy Beef Noodle Soup / Bun Bo Hue

When most people think of Vietnamese food, pho is typically the first dish that comes to mind. It’s the unofficial ambassador of our cuisine — a comforting bowl of beef noodle soup with fragrant broth, tender slices of beef, and silky rice noodles. It’s soft-spoken, approachable, and endlessly customizable, which makes sense why it’s become such a global favorite. But ask any Vietnamese person what their favorite noodle soup is, and more often than not, you’ll hear another name come up with a gleam in their eye: Bun Bo Hue. Once considered the lesser-known cousin of pho, bun bo hue is finally getting its moment in the spotlight — and for good reason.

What is Bun Bo Hue?

Now if you’ve never had BBH or have only heard of its prowess, then you could consider Bún Bò Huế as Phở’s spicy and sassy ass cousin. While the two share some similarities, the differences and beauty of each dish are major.

Bun Bo Hue is a traditional Vietnamese noodle soup hailing from the city of Hue. Its defining feature is its robust and spicy broth, crafted from beef bones, lemongrass, shrimp paste, and chili oil. This soup boasts tender slices of beef, pork knuckles, pig’s blood cubes, and sometimes beef tendon or pork hock, all served alongside round rice noodles. Garnished with a variety of fresh herbs like cilantro, basil, and green onions, Bun Bo Hue is cherished for its rich flavors and hearty ingredients, earning it a spot as a beloved comfort food in Vietnam.

Bun bo Hue’s broth uses both beef and pork bones. It is intensely complex, and the depth of flavor is insane. It really sets itself apart with notes of lemongrass and spice throughout the broth.

The Secret Ingredient

When I traveled back to Vietnam in 2008, I spent time with family I hadn’t seen in years. One afternoon, I watched an auntie in the kitchen preparing bun bo hue the old-school way — with a giant stockpot simmering over charcoal, bundles of fresh herbs on the counter, and that unmistakable aroma of lemongrass, shrimp paste, and chili hanging in the air. But what really stuck with me was one unexpected ingredient she tossed into the pot: fresh pineapple.

I was surprised — I had never seen anyone use pineapple in bun bo hue prior to this. She explained that pineapple’s natural sweetness and acidity doesn’t just brighten the broth but elevates it. The subtle tartness balances the richness of the beef and pork, cutting through the fattiness and adding a depth of flavor that lingers on your palate. It’s not overpowering or fruity — it just adds this gentle roundness that makes every spoonful taste more alive. Additionally, the enzymes in pineapple help tenderize the meat, making the beef shank and pork hock incredibly soft without having to overcook them. It’s one of those small touches that changes everything — and ever since that trip, I’ve never made bun bo hue without it.

It’s my not-so-secret weapon now. Whenever I cook a pot of bun bo hue for friends or family, someone always asks, “Why does this taste so different, so good?” I just smile and tell them: It’s the pineapple.

The secret to amazing BBH broth is fresh pineapple; I picked up this tip during my travels to Vietnam back in 2008, and have used it ever since. Canned pineapple will also do the trick in a pinch. The pineapple adds both sweetness and acidity, which is much needed in the decadent broth.
