Pho Broth

To make a pho broth that is rich and complex in flavor, you have to use real bones. True Vietnamese pho broth is made from beef bones that are slowly simmered for hours in order to extract all the flavor and nutrients from the bones. You can use any kind of beef bones. From marrow, oxtails, knuckles. Any bone will work.

Besides the beef bones, pho broth also uses flavors from cinnamon, cloves, anise and ginger to give that complex flavor. In a pinch, if you don’t have whole cinnamon sticks, cloves or star of anise pods, you can always just use powdered. Even ginger powder can be replaced for the fresh ginger. I recommend adding a teaspoon of ginger powder in place of sliced ginger.

Fish sauce is a major component to authentic keto pho broth as well. Although stinky, fish sauce is from fermented fish and it adds that umami flavor.

Thinly Sliced Beef

It might seem strange that we are adding raw beef and uncooked vegetables to our pho broth, especially if you have never had pho before. However, the hot broth will cook our meat and vegetables as long as they are thinly sliced.

The best way to get very thin slices of strip steak is to freeze it for 35-35 minutes. This will harden it just enough so you can run a very sharp knife through it or slice it using a meat slicer. You can also request thinly sliced steak from your butcher.

Yes, pho is keto! The broth – which makes it pho – is definitely keto approved. Make sure you add low carb vegetables and stick to noodles that are keto friendly like the hearts of palm noodles I use in this recipe. Traditional pho soup used rice noodles. These noodles are too high in carbs.

  1. Traditional Pho is subtly sweet and is cooked with a large chunk of rock candy sugar (substitute granulated erythritol).

    Veggies always includes fresh basil (preferably Thai basil) and/or culantro. Super thin onions as you suggested, green onions and cilantro is also sometimes added. Fresh bean sprouts add crunch. Sliced Jalapeno is optional for some heat. Siracha and Hoisin (definitely not keto unless you make a low carb one yourself) sauce to taste.
    Fresh lime juice really makes this dish shine!

  2. This recipe was awesome! My family loves pho and we have had challenges finding this soup since moving to Colorado from Southern California, where excellent pho is everywhere. The broth was wonderfully rich and super easy to make in my Instant Pot. I added Shirataki noodles, cilantro, green onions and a bit of Siracha (no hoisin). Wonderful recipe….can’t wait to try some of your other keto recipes. Thanks so much!
