I’m so excited to share my low carb pho recipe with you!

Pho is one of my favorite foods ever and is the ultimate comfort food to me. I have so many memories tied to this dish. My husband and I went on our official first date at a hole-in-the-wall pho restaurant after I raved and raved about the soup. I’ve trekked to the local pho joint mid-hangover with my BFFs knowing at the end of our journey we’d all feel 300% better. My sister and I regularly frequented one spot simply because she thought the server was cute and we would talk about what their hypothetical child, Minjiffany, would look like (Minji + Tiffany – I still remember, Tiff!). So many good things come to mind!

Unfortunately, pho is as noodley as they come. The dish is traditionally served with rice noodles, which have a MILLION carbs in them. Well, not a million but close enough. Just 1 cup of rice noodles has 42 net carbs! That’s roughly equivalent to a candy bar. Psh. No. Not anymore, pho.

Or so I thought! You see, after all these years of devouring pho left and right, I had never learned how to make it myself at home. I always swung by my favorite pho place whenever I got a hankering for beef noodle soup; it had become like fast food to me. After going keto, I started to miss my beloved soup, and I just had to make a low carb pho to curb my cravings.

I had learned to make a pretty good bone broth with my pressure cooker but hadn’t experimented with pho broth ever before – let alone a low carb pho broth. It usually takes hours (and hours and hours) to simmer on the stovetop, but I don’t have time for that. At all. I contemplated picking up pho to-go and just tossing out the noodles, but I have a hard time trusting that the broth they make doesn’t have sugar in it. Hint: it does.

So out comes the Instant Pot, using this recipe for reference and I begin constructing my game plan to perfect my version of low carb pho.

The Low Carb Pho Recipe

Rice noodles are out, obviously. I decide Shirataki Noodles are my best-bet to substitute for many reasons. First of all, they have NO carbs! Zip, zero, none. Although they only have 30 calories in an entire bag, Shirataki Noodles are actually quite filling. They also have the same underlying texture and appearance I’m looking for; there’s a little bite to the noodle, and if you choose the long, skinny spaghetti-like strands it looks pretty darn close to the real deal. I have had great success using them for low carb Asian dishes, including stir-fry recipes and even fried rice. I was pretty confident they would work well in a noodle soup, but it turned out better than I had imagined! For this dish, you don’t have to do much with the noodles, just rinse them off in water and strain.

For the broth, I parboil the bones for 15 minutes to remove impurities and increase clarity of the soup. Then I throw everything broth-related into the instant pot: the bones, onion, ginger, fish sauce, and water. I set my pressure cooker for 2 hours on high. When it’s done, I just strain it! You could then use it immediately or make it ahead of time, freeze and boil when you’re ready to use it.

Now, I could just straight up drink this broth because it’s so good. But it wouldn’t entirely be pho without all the fixings now, would it?

Pho Fixings:

  • Lime – A squirt from a lime wedge usually does the trick with minimal amount of carbs
  • Sriracha – It’s delicious, I know. But watch your portioning: there’s 1 gram of sugar per teaspoon, so it is effortless to go overboard on carbs if you are a fan of the rooster sauce or like it super spicy!
  • Chili Garlic Paste – The brand I use (Huy Fong) that is available at most restaurants has less than 1 gram of sugar and reads 0 total carbs on the nutrition label. Better option to make it spicy on a keto diet.
  • Thai Basil Super aromatic, this is a lovely herb for any soup. Plus its low carb!
  • Cilantro – Have at it! This herb is keto compliant.
  • Hoisin Sauce – Not keto friendly! It’s chalk full of sugar! Stay away.
  • Veggies – Bean Sprouts, Jalapeno, Mushrooms, Onion, Scallion, Broccoli are favorites for pho. Use what you like, just be sure to track the carbs for whatever you add. (My low carb veggie list can help you with that!)
  • Meat – A-OK on keto. Select a traditional cut of meat or get creative! Up to you!

The fixings are all optional dependent on preference and taste. A well-constructed broth usually doesn’t need much, so I leave a lot of the sauces out when I enjoy the way my broth turns out. Play around with it to find your perfect combo!

There’s a variety of meats to include in traditional pho as this post over at Serious Eats illustrates, but my personal preference is to use raw flank steak shaved paper thin. You can ask your local butcher to cut it for you or buy a side of the raw beef at your closest pho joint – but I guarantee you’ll get more bang for your buck at the butcher. When you are ready to serve, place the meat in the steaming hot broth in your bowl to let it gradually cook. Then add in the rest of your ingredients.

To serve, place your meat of choice and shirataki noodles in a large bowl and cover in piping hot broth. I would recommend tasting your broth before adding any sauces – you may like it just the way it is. Taste first, then season! Add your desired fixings, mix and slurp away! Enjoy your low carb pho!

I like to plate the pho fixings separately in a community style bowl or plate to share with my family, that way we can all pick our favorite additions to the soup and I don’t have to worry about keeping everyone’s order straight. Even my toddler loves this dish! She demands “SOUP! SOUP! SOUP!” Like mother, like daughter.

If you don’t have a pressure cooker, you could just use the stovetop method. But I would seriously consider getting one to save you some prep time in the kitchen. It’s much easier to stick to a diet when you can prepare things on the fly and make things as uncomplicated as possible. I use an electric pressure cooker called the Instant Pot so I can set it and forget it instead of staring at the stovetop. I’m a bit of an Instant Pot evangelist since getting one for my birthday last year, I use it constantly and preach to my friends and family about it. But there are plenty other pressure cookers out there that will get the job done!

  • How much shirataki noodles would be in the typical restaurant regular bowl of Pho? Seems like it might be more than a 7 ounce typical shirataki noodle package.

  • Hi, I made this recipe for tonight’s dinner. I used organic beef broth, but otherwise followed the recipe exactly. It was DELICIOUS! My hubby practically cried tears of joy! Thanks for sharing!

  • Thank you Thank you! I’ve been on Ideal Protein (keto diet) and this week have been in Vancouvuer / stuck in hotels with their expensive and not so keto friendly menu’s. My saviour was a Vietnamese Pho stand in the casino of all places – and I could choose my broth/veg and protein. When I got home yesterday I realized there is nowhere near me that does it and I quite liked using my protein and veggies allowance in this way. I didn’t put the Shiritaki noodles in just yet until I get the all clear from my diet lead but I put beansprouts in as a substitute. I have a fussy family so I quickly blanched my Shirtaki Mushrooms/Broccoli and Asparagus separately and then put those atop my beansprouts – my thinly sliced beef and some green onion – poured over this broth ………aahhhhh. It smelt devine and hit the spot. Bonus I have enough broth left over for tonight and I now know how simple this is to make. (I also used organic low sodium/0 Carb beef broth – but I will buy some bones and do it the proper way – I am sure the flavour is even more intense. YUM YUM I am so glad I googled 🙂 Thanks! (PS I did two dinners last night as I didn’t think my kid would eat it – he saw me and said I’d eat that if it had noodles in it hahaha – so thats his supper later too!). Yehah!

  • Hi there – just ordered my shirataki noodles online(nowhere to be found in my corner of the world) and am SO excited to try this recipe. Could you describe how to cook the broth without a pressure cooker? I have a slow cooker if this helps.


  • When you cook the broth, did you manually release the pressure or let it do it naturally?? I don’t have a ton of experience with our Instant Pot abs don’t wanna mess this up lol. I’ve been dying for some good pho and was ecstatic to come across your recipe! I’m going to make it this weekend. I can’t wait

    • On broths, I usually let it do the natural release because I’m always a little scared of getting sprayed with liquid on the quick release. It won’t make much of a difference with this recipe, usually quick release is just to prevent overcooking under pressure so you can quickly open the top and take the food out. Pretty important with things like veggies, certain kinds of proteins, etc. But for a soup, you could go either way. If I’m impatient, sometimes I will let the natural pressure release for a while and then bump the release valve manually to speed things up. 🙂

  • Curious — what size is your slow cooker? We made this recipe the other day and my wife was a little worried it was too full with a gallon of water (so we ended up doing the broth in 2 batches). We had borrowed a 6 quarter from friends and were being extra careful since we had never used one before!

  • Are bean sprouts ok? It’s about 5 net carbs for a serving of nine, which is a small serving. Jalapenos aren’t too high in carbs, but have a fair amount of sugar. Fish sauce also has about .7 grams of sugar/tbsp. You would need to incorporate a little more fat in this recipe if you guys are on a strict keto diet. But a good tasting recipe overall. Thanks

    • 5 stars
      Came across your Pho recipe and am drooling!
      Joyfully completing your informationsite sections to receive additional recipes and Low Carb/Keto suggestions.

  • So excited to try this! Which style of noodle do you prefer for this dish? I see they have angel hair, fettuccine and spaghetti… also, can these noodles be found liar locally, like Whole Foods or Trader Joe’s? Thank you in advance!

    • I prefer the skinny ones for sure. I have found shirataki noodles at Safeway in the refrigerated produce section, usually where they store the tofu and refrigerated salad dressings. Hope that helps!

  • I think for best results, try using organic beef joints (I personally use oxtail-it’s rich and filling), organic will make worlds of difference. While parboiling the bones (or oxtail), char the halved yellow onions AND 2 pieces of ginger (sliced lengthwise) to release the sweetness of both, once charred, scrape and rinse the blackened bits off of them and place them in a pressure cooker. Then, add a stick of real ceylon cinnamon, a teaspoon of coriander, a teaspoon of fennel, a few pieces of clove, a couple star anise and a couple black cardamom pods to a dry (cast iron or stainless steel) pan and leave it on med-low for several minutes (careful not too high or it will burn) to release the oils. Throw all the aromatics in a coffee filter and tie it with cooking string and place it in the pressure cooker with filtered water (beware of plastic water bottles, they have particles of plastic in the water) almost up to the 2/3 line (I have a Kuhn Rikon, so IDK if other pressure cookers have those lines) and add the rinsed bones, 1/4 cup of fish sauce, 2T of yellow rock salt (may be omitted) and 1T of coarse kosher sea salt. Cook at 15lbs for 90 min, then use natural release. Ladle broth over prepared miracle noodles, paper thin slices of white onion, thin slices of beef, chopped green onion, torn thai basil, cilantro leaves (no stems) and then squeeze freshly cut lime. Let it sit 10 mins, it’ll be divine by that time

  • Have you (or anyone) tried making chicken pho?? I’m not a huge fan of beef pho but love chicken and miss it tremendously!! Thanks in advance!

  • 5 stars
    So what if I do shortcuts and buy bone broth instead? What changes for the recipe? I don’t really have to ability or access to do beef broth from bones.

    • You just miss out on all the spices/aromatics that are cooked into the pho broth. Traditional southern Vietnamese style pho cooks the broth with star anise, cinnamon, cloves, cardamom, and maybe 1 or 2 others I’m forgetting (Hanoi-style pho has a slightly different spice profile, but I’m not familiar with that one). These spices/aromatics are what makes pho broth different from bone broth. You could probably try putting the spices in a spice bag (or coffee filter) and simmering them in the bone broth for awhile, but I’ve never tried that, so I’m not sure how much of the flavor you get.

  • I can’t imagine this actually taste like traditional pho!. Like real viet pho.. it would be easy for a non viet to make something they believe is similar, but u can’t mimic real pho! That’s my problem. It’s not the real deal

    • It’s not the real deal, but it curbs a craving. Pretty much like any other low carb/ketofied version of an original dish.

      On a side note, I was recently at a Vietnamese restaurant and they had zucchini noodles you could substitute instead of the rice noodles. It was a pretty cool offering and certainly more “authentic”.
