I can’t tell you how excited I am about how this recipe turned out! It is not only gorgeous but it tastes like the real deal…like you got it at a Chinese restaurant. And, not one of those buffet style places either.

You will be proud to serve this dish to your family and company alike. It’s THAT kind of good.

It’s not just “Keto” food. It’s healthy, fresh, delicious food that anyone (Non-Keto kids and family) will love too.

And, did I mention how easy this is?

Low Carb Stir Fry

Let’s get started making Keto Keto Beef Stir Fry

The meat.

Stir fry Steak

I used London Broil because it was on a great sale. I am pretty sure you can use whatever beef cut the you want.

Just make sure to slice it across the grain so that it stays tender. Sometimes I marinate London Broil in apple cider vinegar for an hour or two if I am going to use it in things like stir fry or tacos.

It doesn’t make the meat taste like vinegar. The enzymes break down the meat a bit so that it’s tender.

I did NOT do this with this meat because I was checking it out to see what it would be like if I needed to make a super quick meal for the busy people out there. It came out fine and tender anyway.

One suggestion that I would like to make is to pop this baby in the freezer for a bit before slicing. Not until it’s frozen, but just until it’s stiff. It makes it easier to slice thin.

DO NOT OVERCROWD YOUR PAN. You’ll never get a good sear.

You can make as many servings of this dish as you like. Just change the amount of servings in the recipe card below.

I suggest using a large wok like this one if you are going to make the full recipe. And take turns with your meat if the pan looks too crowded.

In these photos I used a smaller pan because I was checking out the recipe card servings calculator to make sure it tasted the same in different serving sizes…it does.

I am not trying to pat myself on the back too much here but we do try out several different versions of recipes that we like before we post them. Yeah, it takes us longer and we eat a lot of fails lol.

I am lucky that Thom is almost as happy with leftovers as he is with a new dish.

Here is the finished product and I let this one do it’s thing before I flipped the meat…

The Ginger Make the Keto Beef Stir Fry Flavor

I used to hate ginger. But I have grown to enjoy it because the flavor mellows so much when you saute it and it adds an almost floral note to this dish. ( Ginger is a theme in Asian Cooking).

It will not over power the dish like I was afraid it would.

To make your dish look and taste gorgeous you’ll need to julienne the ginger like this…

Cooking the meat first and removing it from the pan while you cook the veggies is key with this Keto Beef Stir Fry Dish.

You will get all of the flavor from the meat but you won’t over cook the steak into shoe leather.

One of the other things that I notice about this method the most is that the meat doesn’t become “cloudy” looking from the vegetable juices. It somehow looks “cleaner” to me.

This recipe tastes great but don’t underestimate the visual appeal here. It’s important and affects peoples perception of taste more then you know. You deserve beautiful food!

I used frozen bell peppers for ease but there are some other benefits too.

Not all frozen veggies hold up in the same way. But frozen bell peppers are great for a couple of different reasons.

First of all, they are usually less expensive than fresh peppers ( at my local Safeway at least).

Second of all, they are a time-saver because they are pre-sliced. And, third because they are frozen at their peak. This helps keep all of the vital nutrients intact. You might as well get all of the benefits of your food.

So unless you really like slicing bell peppers than you should give the frozen kind a whirl.

You should never use sesame oil  with the heat on.

Sesame oil is delicate and has a low smoking point. It is a finishing oil and should be added after the heat has been turned off ( just like truffle oil).

This one is full of flavor, organic and better than what I have found in my local store…in the sticks.

You can add the green onions after the heat has been turned off or you can let people add their own at the table.

Sliced green onion is a staple in Asian cooking. But with that said, I know that not everyone loves them. My teen is a perfect example.

She’ll eat regular cooked onions in a dish, but if I sprinkle fresh onions on top of her food than you can be sure there will be a little pile of them going into the garbage at the end of the meal. Why waste ’em?

If you are not familiar with Chinese cooking than you might be surprised at the addition of erythritol at the end of the process.

You know that yummy flavor at your favorite Chinese take-out joint? The one you just cant put your finger on? The thing that makes you want more? It’s sugar.

Chinese restaurants have long been adding sugar to their dishes in the U.S. (I don’t know about in China since I have never been).

But I do know this:

For years I couldn’t figure out why my stir fry tasted Tex-Mex-ish unless I bought one of those little packs of Chinese Sauce. I was missing the sugar.

We don’t do sugar here on our Keto Site and erythritol is the best option as as as we are concerned. It’s not a lot and will not give you an upset belly.

The sweetness takes stir fry to the next level in tasting “authentic”.

You could serve this over cauliflower rice or zoodles but you don’t have to.

This dish is satisfying on it’s own and the hearty portion of steak will keep you full.

If you are trying to go “all out” with this dish than you should consider the Keto Fried Rice to go with it.

It will take away the “time-saving” portion of this dinner because Keto Fried Rice takes a while to make ( There is a lot of chopping and frying going on).

But, you’ll probably have some leftovers for lunches and snacks…an important consideration around here for sure.

And lets not forget the one of the most important parts of the dinner meal…

Consider Dessert to go with Keto Beef Stir Fry

Traditionally (here in the U.S.), Chinese meals are ended with an almond or fortune cookie…but I am not going to attempt fortune cookies because I don’t wanna.

But these Keto sugar/shortbread-esque cookies with a little almond extract will do for almond cookies.

And, we have a big collection of other sweets made Keto-style if those don’t sound like your thing.

These Chocolate/Peanut butter truffle bombs are my current favorite…

Keto Chocolate Peanut Butter Cheesecake Treats

I think that’s it for this recipe…

This recipe is delicious as is but don't forget to use you imagination too.  Add some other veggies like broccoli if you want to.  Change to chili peppers if you would like a little more spice.

  • 1 tbsp soy sauce
  • 1 tbsp fish sauce
  • 2 tbsp toasted sesame oil
  • 1 tbsp Allulose
  • 1 tbsp Sesame seeds *optional

    Ginger for Stir Fry
  • In a large skillet or wok, over medium high heat, fry the steak strips in coconut oil until steak done (no longer pink or until desired).
  • Remove the steak.
  • Add ginger to the wok . Cook for a minute before adding other veggies.
  • Add peppers and onions and cook on high until the onions are translucent and other veggies are as soft as desired. (I like mine when they are still a little bit crisp).
  • Turn to low heat and add the steak back with the veggies.
  • Add fish sauce and cook for one minute.
  • Turn off heat.
  • In the wok, toss with Allulose, sesame oil and soy sauce.
  • Enjoy.


Sesame oil is a finishing oil. You should not use it for frying. The high heat breaks down the oil, and ruins the flavor.

    I was thinking this would be more complicated. Most Asian recipes written by bloggers are. But this was so simple and clean. We loved it.
