I make this three-ingredient sauce every week for whatever protein I have on hand. It's low carb, ready in two minutes, and tastes so much better than anything from a bottle.

I started making this sauce because I was tired of reading ingredient labels on store-bought bottles and finding sugar listed three different ways. I figured if the base was just soy sauce, vinegar, and garlic, I could make it myself in less time than it takes to drive to the store. Three ingredients, two minutes, and it tastes better than anything I’d been buying for years.

The flavor starts with the soy sauce and vinegar working together. The soy sauce brings salt and depth. The vinegar cuts through it and keeps things bright. I rotate between white vinegar, apple cider vinegar, and rice vinegar depending on what I’m cooking. Rice vinegar is my pick when I want something softer. White vinegar gives a sharper edge, especially with beef. The garlic ties it all together, and I always use fresh cloves when I have them. Powdered garlic works in a pinch, but the raw stuff mellows beautifully once it hits a hot pan.

One of my readers accidentally grabbed sesame oil instead of vinegar one night, drizzled it in anyway, and told me it was the best batch she’d made. I tried it on purpose after reading her comment, and she was right. That nuttiness rounds out the whole sauce in a way I didn’t expect. Now I add a small drizzle almost every time. It’s one of those happy accidents that became a permanent part of my version.

I usually double the recipe and store it in a mason jar in the fridge for the week. That way I’m not making a fresh batch every night. I just pour out what I need over whatever protein and vegetables are in the pan, put the jar back, and dinner is halfway done before I’ve even turned on the burner. I use it on chicken stir fry, keto beef and broccoli, shrimp, pork chops, or whatever I have thawed. Two minutes of prep replaces every bottled sauce in the pantry.

The ratio scales easily too. If I’m cooking for one, I cut everything in half. If I’m feeding the whole family or prepping for the week, I triple it and divide into smaller containers. It’s just as flexible as my keto teriyaki sauce, but without any sweetener at all. If you’ve never made a sauce from scratch before, this is the one to start with. No cooking, no emulsifying, no special equipment. I mix mine in a jar and shake.

How to make stir fry sauce

  1. Add the three core ingredients (soy sauce, vinegar, and garlic) to a small bowl or mason jar.
  2. Mix or seal the jar and shake.
  3. Pour out as much as you need over your favorite vegetables and proteins (chicken, beef, or shrimp). I add a thickener like cornstarch or arrowroot powder if I want it thicker.

What is stir fry sauce made of?

This recipe uses only three basic ingredients. They’re pantry staples I always have on hand.

  • Soy sauce: Regular or low-sodium both work. I use tamari when I want a gluten-free option. For soy-free, try liquid aminos or coconut aminos (though coconut aminos runs sweeter, so I add a splash more vinegar to balance it out).
  • Vinegar: I rotate between white vinegar, apple cider vinegar, and rice vinegar. Each one shifts the flavor, so I experiment depending on the protein I’m cooking.
  • Garlic: Fresh cloves are my first choice, but I reach for powdered garlic (1 teaspoon) when I’m short on time.

I have additional flavor add-ins listed below, like ginger or sesame oil.

Stir Fry Sauce

Frequently Asked Questions

Can I use this sauce as a marinade?

I do this all the time. I pour it over chicken or beef in a zip-top bag and let it sit in the fridge for at least 30 minutes (up to overnight). The vinegar and soy sauce tenderize the meat while the garlic soaks in. I switch between this and my chicken fajita marinade or cilantro lime marinade depending on the flavor I'm going for.

How long does homemade sauce last in the freezer?

I've kept mine frozen for up to 4 months with no change in flavor. I freeze it in ice cube trays so I can grab exactly what I need. The garlic mellows slightly after freezing, but once it hits a hot pan I can't tell the difference.

Does coconut aminos work the same as soy sauce in this recipe?

I've used coconut aminos many times and it works, but it runs noticeably sweeter than soy sauce. My fix is adding a splash more vinegar to balance out that sweetness. The garlic flavor actually comes through more with coconut aminos since it's less salty, which I like when I'm watching sodium.

How do I reheat this sauce?

I usually toss refrigerated sauce straight into the hot pan with my protein. It heats through in a minute or two. If I'm reheating it separately, I warm it in a small saucepan over medium heat for about 5 minutes. Microwave works too (10-15 seconds), but I prefer the pan method because the sauce reduces slightly and the flavor concentrates.

Can I use this as a salad dressing?

I do, especially on Asian cucumber salad. I skip the thickener and add a drizzle of sesame oil. It makes a light, tangy dressing that works well on cold noodle bowls and sliced vegetables. I've also tossed it with shredded cabbage for a quick slaw.

What's the difference between this sauce and teriyaki sauce?

My teriyaki sauce is thicker and has sweetener, which gives it that sticky glaze. This one is thinner, sharper from the vinegar, and has no sweetener at all. I swap between the two depending on whether I want savory or sweet. They use similar base ingredients so I make both from the same pantry shelf.

Does this sauce need to be refrigerated?

Yes. I always refrigerate it after making a batch. Homemade sauces without preservatives need to stay cold. Mine lasts up to two weeks in the fridge in a sealed mason jar.

Flavor add-ins I keep coming back to

Whether I’m pouring this over chicken, beef, or vegetables, the three-ingredient base is just the starting point. I almost always add something extra depending on my mood.

My go-to add-ins:

  • fresh ginger (my favorite, especially with chicken)
  • ginger powder
  • garlic powder
  • red pepper flakes
  • sesame seeds
  • sriracha sauce
  • lime juice
  • orange juice *
  • lemon juice
  • pineapple juice *
  • oyster sauce *
  • hoisin sauce *
  • dry sherry
  • sesame oil (a reader added this by accident and I started doing it on purpose, it adds a nuttiness that rounds everything out)
  • black pepper
  • vegetable broth
  • brown sugar *
  • chicken broth
  • fish sauce
  • peanut butter

* These options are higher in sugar. I skip them to keep things low carb.

How to thicken this sauce

The sauce naturally thickens a bit as it cooks down in the pan, but I sometimes want it thicker so it coats the meat and vegetables properly.

Options I’ve tested:

  • 1 tablespoon cornstarch (mix with cold water first to avoid clumps)
  • 1 teaspoon arrowroot powder
  • 1/2 teaspoon xanthan gum (this gives it a silky, glossy texture that’s closest to takeout)
  • 1 egg yolk

What to cook with this sauce

I use this sauce with almost everything in my fridge. The flavor works across proteins and vegetables, so I don’t overthink it.

  • For protein, I rotate between chicken, beef, shrimp, pork, and tofu. It pairs especially well with keto chicken katsu when I want something crispy.
  • Vegetables: snap peas, snow peas, carrots, onions, bell peppers, bok choy, zucchini, broccoli, water chestnuts, bean sprouts, mushrooms. I pull from whatever’s in the crisper drawer.
  • Serve it over shirataki noodles or cauliflower rice.

Storage and meal prep

Refrigerate: I store leftover sauce in an airtight container or mason jar in the fridge for up to two weeks.

Freeze: I pour the sauce into an ice cube tray and freeze it. Once the cubes are solid, I pop them out and transfer to a gallon-size zip-top bag. It keeps in the freezer for up to 4 months. This way I grab exactly what I need without thawing the whole batch.

Reheat: For frozen cubes, I toss them straight into the hot pan with my protein and vegetables. They melt in about a minute. For refrigerated sauce, I warm it in a small saucepan over medium heat for 2-3 minutes or microwave for 10-15 seconds.

Label and date the bag so you remember what you saved.

    I was convinced three ingredients couldn't taste like anything worth pouring over chicken, but here we are. The vinegar and garlic do something to each other that I can't explain, it just works.

    My mom used to make her own stir fry sauce every Sunday and I couldn't have it anymore after going low carb. Made this with the soy sauce and garlic and it took me right back. Didn't expect that at all.

    First time making stir fry sauce from scratch and honestly didn't think three ingredients would cut it. The garlic pulls way more weight than expected. Can you use this as a marinade ahead of time too?

    1. Annie Lampella
      Annie Lampella Mar 5, 2026

      Yes, I do this all the time. Zip-top bag, at least 30 minutes in the fridge, up to overnight. The vinegar starts tenderizing right away and the garlic really gets in there.

    Had no idea three ingredients could turn into anything worth repeating, but the garlic does something once it hits the pan. Made it on a cold weeknight and it's already replaced my go-to bottle.

    Heather Feb 22, 2026

    I only had coconut aminos so I used that instead of soy sauce and figured it would be close enough, but it came out way more mellow and the garlic flavor actually got to shine without everything tasting like salt. Then I grabbed the sesame oil by accident when I was reaching for the vinegar and drizzled some in anyway, and I'm glad I did because now that's just part of my version. This whole sauce took me two minutes on a cold weeknight and I poured it over chicken and zucchini and it was so much better than anything I've bought at the store. I feel like I've been wasting money on those little sauce packets for years. Already have a batch sitting in the fridge for tomorrow.

      That sesame oil slip was a good one. It adds a nuttiness the original doesn't have. Might start doing that on purpose.

      Two minutes is about right! I keep this one on repeat too. Sometimes I'll double the batch and store it in a jar for the week.

    Used coconut aminos instead of soy sauce. Came out a little sweeter but still good on chicken.

      Andre yeah coconut aminos run sweeter than soy sauce. Adding a splash more vinegar helps balance it out if that bothers you.

      Maple syrup pulls it toward teriyaki territory. Not a bad direction if that's what you're after.
