Best Bún Riêu Recipe (Vietnamese Crab, Pork & Tomato Noodle Soup)

Bun rieu is a Vietnamese noodle soup that’s like no other. This soup is prepared with shrimp, tomatoes, meat broth, tofu, vegetables, and many other herbs and spices. Its major component is tofu, but what makes it truly unique are the rieu, which are meatballs made of pork, shrimp, prawns, or crab.

Just like you, at some point, I got tired of ordering bun rieu from random restaurants and getting disappointed. Hence, we went and did the research ourselves and found an easy yet delicious bun rieu recipe that hits just the right spot!

Bowl of Bun Rieu

Here’s what to expect while making bun rieu with us.

Quick and Easy Bun Rieu Recipe

There are a few different ways to prepare bun rieu. Some of these are straightforward, while others need more effort. However, as someone with only a moderate amount of experience in the kitchen, I’d say that making bun rieu is easy and simple. That is, provided that you are aware of the ingredients you need.

Bun Rieu ingredients

If you go to Vietnamese restaurants as often as I do, you’ve definitely noticed that this dish is almost always on the menu. It’s literally that easy to put together! As a result, it is safe to say that whoever developed the Vietnamese crab noodle soup known as bun rieu created it for convenience. As if someone wanted to prepare soup with the ingredients they had and, in the process, made a masterpiece in the kitchen.

If, on the other hand, you are interested in trying something a little bit different, you can look at a slightly altered version of the recipe that we have provided below.

Savory Pounded Mini Crabs

Rieu was created with freshly pounded small crabs, but in this recipe, we’ll be making this with other ingredients. After all, in this day and age, only some enjoy such a resource. Not to mention that pounding crab is extremely time-consuming, laborious, and requires the expertise of a trained professional!

As a result, in this recipe, we will replace it with a can of chopped prawns or crabs and fresh crab meat – an alternative that is less expensive, easier to find, and with flavor that’s just as good.

Canned or Homemade Broth

The broth is a standout component of the Bun Rieu Vietnamese crab noodle soup. Depending on the flavor you’re going for, you can add canned chicken or pork broth. It doesn’t really make a difference which broth you use because they both pack tons of meaty goodness!

You should have no trouble finding canned broths at any of your neighborhood grocery stores. However, if you have the time, you can prepare your own broth by boiling pork bones. To say that homemade broth tastes better than canned pork or chicken broth would be too bold of a statement for me to make. Either way, you are in for a fun time no matter what path you pick.

In my perspective, Bun Rieu already has a lot of flavor because of all its ingredients combined. So, I prefer it with less amount of meat in the broth. However, meat fans can feel free to put as much shredded meat as they like in the broth. To each their own!

Fermented Shrimp Paste

You’ll love the fermented shrimp paste addition if you have a knack for funky flavor. Its strong flavor and aroma add a kick to your Bun Rieu, which I absolutely love. Many people shy away from its strength but don’t worry. We can always tone down the aroma later on!

Shrimp paste is one of the ingredients that you save for later in the process. This way, you can opt in or out of adding more, depending on your preference. In other words, if your bun rieu lacks intense flavor, you can add shrimp paste. If not, then you can keep it as it is.

Pro Tip: Mix in shrimp paste into the entire broth instead of your bowl as you eat. This minimizes the intense aroma of the paste but adds more richness!

We also use a lot of other sauces and pastes in the bun rieu recipe, like fish sauce, crab paste, and so on!

Ketchup for Added Flavor

This might not make sense initially, but trust me when I say it works like MAGIC. I like to believe that putting ketchup on your bun rieu is a cheat code or something like that. I mean, it’s not only a simple way to add spice to your soup, but it also gives you that nice, vibrant red color you are looking for.

In addition, you won’t have to go out and buy a whole bottle of vinegar and tomato paste when all you need is a tablespoon or two of each of those.

But if it still tastes a bit too odd, you can try doing it the other way. Squeeze in a few lime wedges to your bowl, together with some tomato paste and annatto seeds, for some color.

Vegetables and Herbs

This bowl of Vietnamese noodle soup, like any other Vietnamese dish, is incomplete without a variety of greens.

There are two herbs that are absolutely necessary for the preparation of your soup. The first is Vietnamese balm, also known as Kinh Gioi. The second is Tia to, also known as perilla or shiso. The latter is, however, optional!

As for the vegetables, water spinach is going to be the main ingredient. In most cases, you have to add it raw. You also need to cut the water spinach stems with a Dao Che Rau Muong in order to make the leaves softer and chewable. In English, this device is called a water spinach splitter.

This vegetable is only available at certain times of the year. As a result, there may be times when it is either extremely costly or entirely unavailable.
