You can make it quickly in an Instant Pot for a quicker meal, just like we used to enjoy on weekends in Vietnamese homes. Súp nui sườn heo is a beloved comfort food in Vietnam, especially in Saigon, and even makes a great hangover soup with its nourishing, savory flavors.

Vietnamese Macaroni Soup Ingredients

To make a rich and nourishing Vietnamese macaroni soup, you’ll need a handful of familiar ingredients that work together to create bold, comforting flavors. I’ve cooked this soup dozens of times for my family, and it’s one of those dishes that instantly makes everyone feel at home—especially when the weather cools down.

• Pork Spare Ribs
  This is where the magic begins. Pork spare ribs are the soul of this soup. Slow-simmering them builds a naturally sweet, umami-packed broth. Over the years, I’ve found that giving the ribs time to soften unlocks a depth of flavor you just can’t rush. My grandmother used to remind me: “Good soup starts with patient bones.” She was absolutely right.
• Macaroni
  Elbow macaroni is the traditional choice, and it’s fantastic at soaking up the savory broth. I’ve also swapped in rotini and fusilli when I was low on pantry stock, and those worked well too. The key is choosing pasta that holds its shape and absorbs flavor without getting mushy.
• Carrots
  Chopped carrots bring gentle sweetness and vibrant color to the bowl. They also add a soft crunch that balances the richness of the meat. I used to skip them—until I realized how much they brighten up the soup. Now, they’re a must.
• Onion
  Onions bring another layer of flavor to the broth. I usually simmer them whole with the ribs and fish them out before serving. That way, you get the sweetness without the texture overpowering the other ingredients. My mom always did it this way, and now it’s part of my own cooking routine.
• Fish Sauce
  A touch of fish sauce gives this dish its signature Vietnamese flavor. It’s packed with umami and balances the broth beautifully. I once made a batch without it—never again. It’s that essential. If you're new to it, start with a little and taste as you go.
• Chicken Bouillon
  When I don’t have time for a long simmer, chicken bouillon is my go-to shortcut. It deepens the broth’s savory flavor quickly. Just a small spoonful can really elevate the whole pot, especially on busy weeknights.
• Black Pepper
  A small sprinkle adds warmth and enhances every other ingredient. I always finish my bowl with a pinch before serving—it gives that final touch of homemade comfort.
• Salt
  Salt pulls everything together. It highlights the natural flavors in the meat, veggies, and broth. I recommend starting light and adjusting after tasting. That way, you don’t overdo it early on.
• Water
  Water is the foundation that lets every ingredient shine. It helps extract all those rich, slow-cooked flavors and transforms basic pantry items into something truly special.

One of the best parts about this soup is how accessible the ingredients are. Most of them can be found in any Asian grocery store—or online if needed. Whether you're cooking a quick family meal or prepping a cozy weekend treat, this Vietnamese macaroni soup delivers warmth, flavor, and nourishment in every bite.

Expert Tips for best Vietnamese Macaroni Soup

• To make Vietnamese macaroni soup truly rich and clear, start by blanching the bones. This simple step helps remove blood and scum, which can cloud the broth. I first learned this from my mom when I was around seven. We were in our small kitchen, and she showed me how clear broth always starts with clean bones.
• Keep the simmer gentle and steady—never a rolling boil. My mom always said the secret to deep flavor is low heat and patience. And she was right. The difference in taste is huge.
• Don’t toss out the meat after blanching! Once simmered, the bits on the bone turn soft and flavorful. I remember sneaking little pieces off the bones when Mom wasn’t looking—it was always the best part to me.
• To level up your broth even more, use the stems of fresh cilantro. They’re packed with flavor and work great in simmering soups. Just avoid soggy or old ones—they’ll turn the broth bitter.
• Do all these steps, and you’ll get a clean, deeply savory soup that tastes just like the ones I grew up with. Trust me, it's worth the little extra effort.

How to Make Vietnamese Macaroni Soup

Let’s make a delicious and comforting Vietnamese Macaroni Soup with pork spare ribs! Cooking the ribs in an Instant Pot for about 35 minutes will make them so tender that they’ll practically slide off the bone. 

If you don’t have an Instant Pot, don’t worry—you can use a regular pot, but it will take longer. Once the ribs are cooked, we’ll simmer the meat to enhance its tenderness before adding macaroni and vegetables. 

This recipe is simple yet flavorful, perfect for a hearty meal that your whole family will love. I’ve made this many times, and trust me, it’s one of those dishes that brings warmth to the soul.

Step 1: Parboil Pork Spare Ribs

Start by adding the pork spare ribs to a pot with enough fresh water to cover them. Bring it to a boil and let it cook for about 10 minutes. 

This step helps remove scum and impurities, resulting in a clear and clean broth. 

Once you see the water turning murky and foamy, discard it, rinse the ribs thoroughly, and set them aside.

 I used to skip this step when I first learned to make this soup, but I quickly realized that parboiling makes a huge difference in the broth’s clarity and taste!

Optional Step: How to Cut Carrot Flowers

Want to make your soup look extra special? 

Try cutting the carrots into cute flower shapes! Simply peel and cut the carrots into small sections, then make shallow cuts at an angle to shape them like flowers. 

This little trick not only adds a fun touch to the soup but also makes it more appealing—especially for kids. I remember the first time I served these to my niece; 

she was so excited about the "flower carrots" that she ate all her veggies without hesitation!

Step 2: Make Broth for Vietnamese Macaroni Soup

Now, let’s build a flavorful broth. In an Instant Pot, add the rinsed pork ribs, carrots, onions, chicken bouillon, fish sauce, black pepper, and a pinch of salt. 

Stir everything well, then seal the Instant Pot lid and set it to pressure cook on high for 20 minutes. 

If you're using a regular pot, let it simmer gently for 40-60 minutes until the pork is fall-apart tender. 

The key here is patience—the longer it simmers, the richer the flavor!

Step 3: Cook Macaroni for Vietnamese Macaroni Soup

While the broth is simmering, it's time to cook the macaroni (or any short pasta like rice macaroni, fusilli, or elbow macaroni) in a separate pot. 

I always follow the package instructions to get the perfect texture—overcooking can make the pasta too soft and mushy. Once cooked, drain the pasta and set it aside. 

Trust me, cooking it separately is a game-changer! It keeps the broth beautifully clear and prevents the soup from getting overly starchy, which is something I learned after a few messy attempts.

Step 4: Release the Steam

 When the Instant Pot finishes cooking, it's time to release the steam. Carefully turn the steam release handle to the venting position. 

Be extra cautious—the steam is extremely hot! I always use oven mitts to protect my hands because, believe me, I’ve made the mistake of underestimating it before. 

Wait until the float valve drops completely before opening the lid. Patience is key here, and it’s worth it for a safe and smooth cooking process.

Step 5: Taste & Adjust (Súp Nui)

Now comes the fun part—tasting! Remove the onion from the pot and take a sip of the broth. Adjust the seasoning as needed. 

If it’s too salty, add a bit more water. If it needs more depth, a splash of fish sauce or a squeeze of lime can work wonders. 

I always do this step with my mom’s advice in mind—seasoning is all about balance!

Step 6: How to Serve (Súp Nui)

Time to put it all together! Divide the cooked macaroni into serving bowls. Ladle the hot, flavorful broth over the pasta and add the carrots and pork ribs to each bowl. 

For the finishing touch, garnish with fresh cilantro, crispy fried shallots, a dash of black pepper, and a squeeze of lime for a refreshing zing. 

If you love spice, add some chili oil or Thai chili peppers for an extra kick.

This dish has been a staple in my home, especially on chilly evenings when I need something comforting yet easy to prepare. Give it a try, and I’m sure it will become a favorite in your kitchen too!

Leftovers & Storage

From my 7 years of hands-on cooking experience, I’ve found that the best way to store leftover Vietnamese macaroni soup is by keeping the broth and macaroni separate. This simple method helps preserve texture and flavor. If you store them together, the macaroni absorbs too much broth and turns soggy—something I learned early on during a week of batch-cooking for my family. To avoid this, I always place the noodles and broth into different airtight containers.

Once the soup has cooled, store it in the fridge. This keeps it fresh and safe for up to 4 days, which is ideal for busy weeks or meal prep. When you're ready to enjoy it again, reheat gently on the stovetop or in the microwave. I suggest adding a splash of broth before warming—it revives the soup and keeps the texture just right. This step is especially helpful when you’ve made extra for future meals.

If you’re prepping ahead, trust me—keeping the macaroni and broth apart is a game changer. It stops the pasta from swelling too much and keeps your soup tasting freshly made, even days later.

How to Reheat: Microwave Method

Another easy option is to microwave súp nui sườn in a heat-safe bowl.

I recommend heating the macaroni first for about a minute, then pouring in the broth and giving it another quick warm-up.

Doing it this way helps everything reheat more evenly without drying out the pasta or overcooking the pork.

Microwave times vary, but usually 1–2 minutes per part works well. I’ve learned this the hard way—once I overheated it and ended up with mushy noodles. So now I always go slow and check halfway through!

How to Reheat: Stovetop Method

If you’re using the stovetop, just place the amount of súp nui sườn you need into a small pot.

Set your burner to low or medium heat, and gently let it warm through until it’s steamy and hot.

This keeps the broth flavorful and stops the macaroni from turning too soft.

I’ve reheated it this way many times—especially when I meal prep a big batch. It helps the soup stay as close to fresh as possible without changing the texture.
