This 3-ingredient Stir-Fry Sauce recipe is easy and delicious. Simply whisk and pour it over your stir fry. Meet your new instant weeknight staple!

Vegetable stir fry in a bowl with rice and  3-ingredient stir fry sauce.

I kept this stir-fry sauce recipe very simple because truly, 3 ingredients are truly all you need for a remarkably tasty result, and I think of this as a weeknight lifesaver when there’s nothing in the house.

The simplicity might prompt skepticism but I did not sacrifice tastiness for ease, trust me.

The chicken and broccoli stir fry is cooked in a large skillet.

It can, however, absolutely be as a jumping-off point, and I’ll give you suggestions on what (and how much) to add if you’ve got a few extra minutes and a well-stocked kitchen.

What is Stir-Fry Sauce Made of?

  • Broth: in a simple recipe like this, you want to have a flavourful base. Choose chicken, beef or veggie broth, something that you like.
  • Soy sauce: this both seasons the dish (adds salt) and offers a nuanced umami flavour and slight sweetness from the glutamate-rich fermented soybeans. If you’re using an unsalted broth, keep adding more soy sauce to taste until the stir-fry sauce tastes sparkling and savoury like a good potato chip.
  • Cornstarch: this is the sauce thickener. It produces a clear, glossy sauce that coats the stir fry beautifully with lustre and deliciousness.

Flavor Boosters

  • OPTIONAL flavourings: add some totally-supplementary but welcome flavour-boosters like garlic, ginger, chile, scallions, etc. if you like. See below for exact measurements.

How to Make Stir-Fry Sauce From Scratch

  • Pour the soy sauce in a large glass measuring cup and whisk in the cornstarch until smooth. It is truly key to stir the cornstarch into the soy sauce to make a smooth slurry before adding heat or more liquid. Starch needs to be dissolved cold or else the heat will make it start to hydrate and swell. When that happens, lumps are inevitable. And whisking it smoothly into a small volume to start is way easier than whisking it straight into the whole thing.
  • Whisk the broth into the soy sauce/cornstarch mixture until smooth. It’ll be cloudy, that’s normal.

OPTION 1: cook the sauce separately

  • Add the sauce to a medium saucepan, turn heat to high and bring to a boil. The sauce is done once it goes from a thin consistency and muddy opaque colour to a glossy, clear caramel colour and thicker consistency.

OPTION 2: cook the sauce in the same pan

  • Once your stir fry is 90% done (veggies are crisp-tender, meat, if using) is cooked nearly to desired doneness), simply pour the sauce over everything and the hot food will thicken the sauce in less than a minute.

How Much Stir Fry Can I Make With This Stir Fry Sauce Recipe?

This recipe makes 1 3/4 cups of stir-fry sauce, which is enough to nicely coat 8 cups of chopped veggies plus one pound of protein.

If you’re cooking less than that, don’t fret – too much spoon-licking sauce is never a bad thing.

Just make sure to cook plenty of rice or noodles to soak it up.

What Can I Add to Stir Fry For Flavour?

Ingredients for broccoli and chicken stir fry on a counter.

Add any or all of these flavour boosters to the basic stir-fry sauce recipe. Here are some quantities to use as a starting point:

  • 3 cloves garlic, minced
  • 1 tbsp minced ginger
  • 2 tbsp minced scallions
  • 1 tbsp oyster sauce
  • 2 tbsp Chinese rice wine or dry sherry
  • 1/2-1 tsp crushed red chili flakes
  • 1 tsp toasted sesame oil
  • 1 tsp honey

What Can I Use Instead of Soy Sauce in Stir Fry?

Adding broth cornstarch-soy sauce mixture.

Tamari is the perfect gluten-free alternative to soy sauce if you are avoiding wheat for whatever reason.

If you simply don’t have soy sauce on hand, use a tablespoon or two of miso paste for a similar effect.

  • ¼ cup soy sauce divided use (see notes)
  • 2 tbsp cornstarch
  • 1 ½ cups broth (chicken, veggie, or beef are all excellent)


  • Measure broth into a large spouted measuring cup and add 2 tbsp of the soy sauce. Taste it, and add remaining soy sauce to taste (see notes).
  • Whisk in the corn starch until completely dissolved. It'll be cloudy, this is normal.


  • Pour the sauce to a medium saucepan, turn heat to high and bring to a boil. The sauce is done once it goes from a thin consistency and muddy opaque colour to a glossy, clear caramel colour and thicker consistency.


  • Once your stir fry is 90% done (veggies are crisp-tender, meat is cooked through) pour the sauce over everything.
  • The sauce will come to a rapid simmer and thickens typically in less than a minute. The sauce is done once it goes from a thin consistency and muddy opaque colour to a glossy, clear caramel colour and thicker consistency. (If you prefer a thicker sauce, see notes below).



  • This recipe makes 1 3/4 cups of stir-fry sauce, which is enough to nicely coat 8 cups of raw, chopped veggies plus one pound of protein. 
  • The saltiness of the sauce will depend on the saltiness of your broth. Start with 2 tbsp of soy sauce and add more by splashes to make sure you don’t make your sauce too salty.  
  • I like the concentrated bouillon that comes in a jar (like Better than Bouillon) and dilute it with water per manufacturer’s instructions instead of opening a carton of broth. You only need 1 1/2 cups, and this will save you finding a purpose for leftovers.
  • Sauce thickness: as written, this is a glossy sauce of pouring consistency  (like the thickness of sweet chili sauce not the thickness of BBQ sauce). However, different meats and veggies release different amounts of moisture so there is some variability to the thickness of the final sauce.
    To make the sauce thicker, add 1 tbsp more cornstarch to  2 tbsp cold water. Whisk until no lumps remain, then stir it into the pan. Let it bubble up and thicken and repeat if needed. 
  • You may substitute the soy sauce with wheat-free tamari for a gluten-free version.
  • You can add any or all of these flavour boosters as variations on the basic stir-fry sauce recipe: 3 cloves garlic, minced, 1 tbsp minced ginger, 2 tbsp minced scallions, 2 tbsp Chinese rice wine or dry sherry, 1/2-1 tsp crushed red chili flakes, 1 tsp toasted sesame oil

I made this for my boyfriends work lunch to pour over his his chicken, rice and veggies. The sauce is good but just a tad bit too salty. I added garlic and red pepper flakes to mine to balance it out but it’s still a little salty if you really soak stuff in it. If you have trouble thickening it I added just a dash more of cornstarch and made sure to really baby it on the heat and stir super frequently. My boyfriend loved it though and it’s been my favorite easy sauce to do so far.

Taste was great for a base. I did add 1 tsp of sesame oil which I’d think would help and 2 TBSP of white wine. Maybe add more corn starch next time? Thickening sauces is always hard for me. Great base! Will add some ginger next time. Good-bye Kikkoman stir-fry sauce!

Hi, I am definitely going to try this! I was looking for a Chai tea recipe and looked through your site. I was happy to find this one. I do have a question. I have some turkey broth I want to use because the flavor is incredible but it already has a lot of salt. Is there a “soy” flavor substitute (other than low salt soy), that would give the dish its “Asian” flavor as soy gives? Usually I don’t add salt to my soup stock but you know Thanksgiving bones make the best stock ever and I would love to use it in a stir fry. Any ideas? I am going to add some sesame oil to. Is there something else I might add? Thanks.
