A plate of food with broccoli, with Beef and Steak

Steak Stir Fry

Steak stir fry is just as easy as take-out, but it’s so much healthier. Low carb, keto friendly, and bursting with Asian flavors. 

When I was a kid my parents used to make stir fry using a bag of frozen vegetables and some chicken breast.

I loved it then, but nowadays I just can not do the frozen vegetables.

Am I the only one who thinks they get terribly icky after being frozen? They just get so soggy when you cook them and I am definitely more of a tender-crisp girl when it comes to my veggies.

This steak stir fry recipe starts with fresh vegetables and they come out perfectly tender-crisp and bursting with flavor.

Also, did I mention there is steak? I mean, you literally can not go wrong with steak, in my opinion. It’s my absolute favorite thing to eat.

Anyway, this low carb stir fry can be totally customized using whatever low carb vegetables you prefer. This time around I went with bell peppers, broccoli, and onions. I’ve made this with cauliflower and either diced or spiralized zucchini as well. Brussels sprouts would be tasty and so would some chopped cabbage or green beans.

Basically, what I’m saying is that this low carb stir fry can handle just about whatever veggie you throw at it. So good!

How to make low carb stir fry sauce:

Asian food tends to be absolutely full of sugar, which is probably a big reason everyone loves it so much.

It’s got that nice balance of sweet, savory, spicy, salty – all good things to have in one dish, right?

I make my low carb stir fry sauce with this honey substitute (affiliate link). It works just like honey would in this recipe and doesn’t have any funky aftertaste. This product uses xylitol and has 1 net carb per tablespoon.

I combine the honey substitute with soy sauce, vinegar, garlic, ginger, and chili paste.

Chili paste (affiliate link) is one of my favorite ingredients and I spread it on eggs and add it to dishes all the time. It adds a great spice to foods.

This low carb stir fry sauce just gets whisked together and poured over the stir fry. Easy as can be.

How to make beef stir fry:

I’m starting with sirloin for this recipe, but you can use any cut of beef that you prefer.

I slice my steak into bite-sized pieces or strips, depending on my mood and cook it over high heat just long enough to brown the outside.

Next, I pour in my low carb vegetables – in this case, we’re using broccoli, bell peppers, and onions.

Once your vegetables have cooked for a couple of minutes, whisk together your beef stir fry sauce and pour that right into the pan.

Cook for another couple of minutes, stirring the whole time, until everything is cooked to your liking and coated in that glorious stir fry sauce.

You’re done! Wasn’t that easy?

    Do you really need the honey/honey substitute in the recipe? Your recipes are really good. I have made a few but plan on making many more.

      You could skip it, but most Asian sauces are sweet and we think it helps to balance the flavors. You could use a granular sweetener too, so long as you let it dissolve.

  2. This recipe sounds great! Can’t wait to try it. I took a fall in September just after I found your web site and started getting the Keto recipes collected. I broke my left wrist and had a laceration on the left side of my face from that fall. I have been in a brace for 8 week on that wrist but have been working on getting recipes and ingredients together. Along with reading up on Keto and reviewing the information you send me. Think I am finally ready to proceed. This will be among the first recipes I will try. Thanks for all the information and recipes you provided.

      Hi Lan! So glad that you’re healing and doing better! Hope you love the recipes. 🙂

    Great recipe!! Just tried it!! I didn’t use the sweetener subsitute, but I did have candied ginger, so I just used that. It worked well!!

    I also do the velveting with bi-carb of soda on all my stirfry meats – makes the meat so tender. I use 1/4 teaspoon bi-carb to 1/4 cup water and let sit for at least 45 mins in the fridge. Wash thoroughly and pat dry with a paper towel.

      I’m not sure what your dietary restrictions are, but if you’re following a strict/clean keto diet, you might want to swap in coconut aminos for the soy. I follow keto with a closer watch on carbs than ingredients so soy is fine for me.

  5. To make it just like the chinese take out we ‘velvet’ our meat which is just mixing 1tablespoon of water with 1 tablespoon of bicarb soda and mixing the paste through the sliced meat. Leave for 20 minutes. Rinse thoroughly important to make sure all bicarb is rinsed off otherwise stirfry will bubble and taste soapy. Meat then melts in your miuth same texture as chinese takeaway! Can be done with all stirfry meats.

      It’s just a sugar free option that tastes like honey. I like to the one I use in the post.

  6. I just found your site. Your stk stir fry sounds great and I can’t wait to fix the egg Ava ado salad

        Not certain why you bother with the imitation honey. While nature’s hollow is 11 g of carbs, other honey substitutes are EXACTLY the same as sugar at 17 g. While the glycemic index may make a difference for diabetics, for those on keto carbs are carbs. Not just kvetching, looking for an explanation to learn from.

        1. Karly Campbell

          Hi Nicole! I count net carbs rather than total, as do many people following keto. I deduct fiber and sugar alcohols – sometimes all of the sugar alcohols and sometimes just half, depending on the type. You’ll have to decide what you’re most comfortable with yourself and proceed accordingly. 🙂

          1. Your recipe looks fantastic. Thanks for sharing.

            The honey a substitute that you recommend contains xylitol. Fine for humans but deadly for dogs.

            Xylitol is extremely toxic to dogs. Even small amounts of xylitol can cause hypoglycemia (low blood sugar), seizures, liver failure or even death in dogs.

            Only 0.1 gram of xylitol per 2.2 pounds of body weight can cause hypoglycemia, while only . 5 grams can cause liver failure. Since a piece of sugarless gum can have between 0.3 and 1 gram of xylitol, it will only take a few pieces to poison a dog. There are 190 grams of xylitol in 1 cup of the sweetener.

            I never knew this and many other dog owners might not either. I’m sure people’s dogs would also love your beautiful stirfry so it will be good to warn people not to share.

    Just found your site and I love the sound of your recipes. I’m looking forward to trying them out soon!

    Thanks for this! I love that you didn’t include corn starch (like so many do!) Can I use apple cider vinegar or does that not matter?

    1. Karly Campbell

      Either type of vinegar will work fine! I just prefer white vinegar, but I know a lot of people like the apple cider. 🙂
