Keto Beef Broccoli Stir-fry

Keto Beef Broccoli Stir-fry is our at-home version of a classic Chinese restaurant dish. For most, Chinese restaurant food is not part of their low carb diet. Simply too many carbs, either from sugar in the sauces, or corn starch in the thickeners. However, Joanie makes a delicious savory and sugar-free sauce that is thickened with Xanthan Gum for this recipe. The result is a perfect Keto beef recipe. If you are missing Chinese food, try this low-carb version tonight!

We love cooked mushrooms served with any dish. Especially when a gravy is part of the recipe. They go together so well. You can see a perfect example of this classic combination in our Keto Chopped Steak with Mushroom Gravy recipe. Mushrooms and gravy are also central to our Chicken and Mushrooms in a Garlic Wine Sauce recipe. Joanie’s Chinese sauce for this recipe is very much like a gravy.


Beef is the main player in this recipe. Some recipes call for using flank steak that has been cut across the grain. However, unless you marinate the flank steak for a long time, it is hard to avoid a tough and chewy result. Joanie likes to use sirloin steak instead. Cut into approximate 3 inch strips and trimmed of most fat is her preference. It is fairly lean and starting with thin strips will mean less cooking time over high heat and a delicious beefy taste.

To enhance the beefy taste, Joanie makes a delicious sauce that is both low-carb and sugar free. She uses coconut aminos in place of soy sauce to keep the carbs down. Chinese fish sauce and sesame oil add even more Chinese flavor. To replace the sugar normally found in Chinese sauces, Joanie uses Sukrin Gold. This brown sugar substitute is perfect for making Keto Chinese sauces. Garlic is a necessity for taste in this sauce and just a bit of Sriracha adds the needed heat. You will love the flavor of the marinade and the sauce it makes.

Preparation Tips

The first tip to prepare Joanie’s Beef and Broccoli Stir-fry into make sure all of your ingredients are ready to go before you start. Chinese food cooks quickly! That goes for your plates, as well. Set the table and be ready to go! In fact, you might be smart to have your guests or family seated at the table – it is best served hot.

Also, make sure your beef is marinated and maintained at room temperature. You can see by our photos that it should be cut into thin strips. We actually found that many markets will sell thinly sliced sirloin beef for stir-fry recipes. Go for that! The broccoli and mushrooms are actually best cooked separately. They will be fine on a plate waiting while you sear the meat. Just make sure that before you toss in the garlic you remove the wok from the heat – it will cook rapidly and you do not want it to burn.
