Authentic Flavor, Low Carb Mongolian Beef
Traditionalists usually rely on tons of brown sugar for the sweetness and cornstarch to get that thick, glossy sauce. We toss those out! For that perfect sweet-savory vibe, I use monk fruit to mimic the sugar without spiking your levels. If you love searing your beef first, you definitely want to check out my advice for getting those perfect edges on your steak, which applies right here! And for the thickening? We’re using the power of xanthan gum to get that lovely coating effect, turning this into a stellar No Sugar Mongolian Beef experience.
Essential Ingredients for Your Low Carb Mongolian Beef Recipe
Okay, stop whatever you’re doing and look at this ingredient list. This is where the magic—and the low-carb victory—is won! We need really good beef here so that when it gets coated in that sauce, it sings. I always grab flank steak because it slices beautifully against the grain, which is key for tender bites. Check out my thoughts on slicing steak for the best texture; it’s important!
For the pantry staples, we are keeping things simple but high impact. You absolutely need fresh garlic and ginger—don’t even think about the jarred stuff here; the fragrance is non-negotiable for any Low Carb Stir Fry.
Our sauce build is totally clean:
- 1.5 lbs flank steak, sliced super thin (against the grain, remember!)
- 1 tablespoon avocado oil (for high heat searing)
- 1 tablespoon sesame oil (for flavor layering later)
- 4 cloves garlic, minced fine
- 1 tablespoon fresh ginger, grated
- 1/2 cup low-sodium soy sauce or tamari
- 1/4 cup water
- 1/4 cup erythritol or monk fruit sweetener (make sure it’s granulated!)
- 1 teaspoon xanthan gum (this is our secret weapon!)
- 1/2 teaspoon black pepper
- 2 green onions, sliced for that final pop of color
- And if you want crunch, toss in 1 cup of broccoli florets!
Ingredient Notes and Simple Substitutions for Low Carb Mongolian Beef Recipe
This is where folks get nervous about adapting classics, but please relax! Making a great Quick Low Carb Beef Meal happens when you treat those substitutions right. If you can’t swing erythritol, allulose is an amazing keto sweetener that browns a little more nicely, though any granulated monk fruit blend will work. For the soy sauce, if you’re avoiding soy or gluten, swap it out 1:1 for coconut aminos—it gives you that deep umami flavor we need for this Easy Keto Beef Recipe.
We’re keeping the ingredient list tight, but these swaps ensure we stay perfectly compliant!
Achieving a Thick Sauce Low Carb Stir Fry
Okay, let’s talk about xanthan gum, the hero of our Thick Sauce Low Carb Stir Fry. You cannot just dump this into the hot liquids; seriously, don’t do it, or you’ll end up with white clumps that look like tiny jellyfish! You need to create a cold slurry first. Take just one tablespoon of cold water and whisk in the teaspoon of xanthan gum until it’s totally smooth before you add it to the simmering pan. It thickens immediately, so start small. Less is almost always more with this stuff. If you add too much, your sauce will turn into a solid paste before you can blink!
Step-by-Step Instructions for Your Low Carb Mongolian Beef Recipe
Time to cook! This whole thing comes together so fast, which is why it’s one of my favorite quick low-carb beef meals. You really need to have everything measured and ready to go before you even turn on the stove, especially because the final thickening happens in seconds. It’s all about flow, just like any good Low Carb Stir Fry!
Preparing the Beef and Sauce Base for Keto Mongolian Beef
First thing: slice your flank steak thinly against the grain—this is super important for tenderness! Put the strips in a bowl. Now, in a separate little bowl, whisk together all your wet sauce components: the soy sauce or tamari, the water, your keto sweetener, and that black pepper. Give it a good swirl until the sweetener starts dissolving. Once that’s done, set that sauce bowl aside right next to your stove. Easy peasy!
Searing the Beef and Building the Low Carb Asian Dinner Flavor
Get your big skillet or wok screaming hot over medium-high heat, then add your avocado oil. You *must* sear the beef in single, uncrowded layers—if you dump it all in at once, it steams instead of searing, and steamed beef is sad beef! Cook it in batches until it’s nicely browned on both sides, then scoop it out onto a clean plate. Now, turn the heat down a little. Add your sesame oil, toss in that minced garlic and grated ginger, and cook them for just about 30 seconds until your kitchen smells incredible. If you decided to use broccoli, throw it in now and let it get a little color.
Thickening the Sauce for the Best Keto Beef Stir Fry Recipe
Toss the seared beef back into the pan with your aromatics and any veggies. Pour that premixed sauce over everything and bring it up to a gentle simmer. Remember that xanthan gum slurry we talked about? Slowly, slowly whisk that cold slurry into the simmering sauce. Keep stirring until it visibly thickens and coats the beef—this takes maybe 45 seconds. Seriously, watch it closely. Once it looks perfect, yank the whole pan off the heat immediately so it doesn’t turn into glue. Top with green onions, and dinner is done!
Serving Suggestions for Your Low Carb Mongolian Beef Recipe
Now that your amazing, flavorful **Low Carb Mongolian Beef Recipe** is ready, you need something to soak up every last drop of that sticky sauce. Forget white rice, obviously! The perfect pairing here is either delicate, fluffy cauliflower rice or the genius texture of shirataki noodles. Shirataki noodles are practically zero carbs, so they are my favorite choice for a complete **Low Carb Dinner Ideas Beef** night.
If you want a bit more substance on the plate, my recommendation is always to serve this over steamed greens like bok choy or stir-fried cabbage. If you need more ideas for beef-based keto meals, you have to check out my post on other Low Carb Dinner Ideas Beef. It’s loaded with inspiration!
Tips for Success with Your Low Carb Mongolian Beef Recipe
You’ve got the technique down, but here are a couple of quick tweaks that take this from good to “Why did I ever order takeout?” I swear by using fresh, zesty ginger—the dried stuff just doesn’t cut it here; the clean brightness is essential for our Low Carb Asian Dinner profile. Also, when searing the beef, don’t rush it! If your pan isn’t hot enough, the oil cools down, and you end up boiling the meat instead of getting that nice, craggy sear that holds onto the sauce.
Finally, taste the sauce *before* you add the xanthan gum slurry, seriously. That allows you to adjust your sweetener or saltiness perfectly while everything is still liquid and cooperative. It guarantees this will be the Best Keto Mongolian Beef you’ve ever made!
Storage and Reheating Instructions for Leftover Low Carb Mongolian Beef Recipe
This Low Carb Mongolian Beef tastes just as good (maybe even better!) the next day, trust me. Pop any leftovers immediately into an airtight container—don’t leave it stewing in the hot skillet! When you want to reheat it, the stovetop is your absolute best friend. Use medium-low heat. If you do use the microwave, keep the power set to about 60% and heat in short bursts, stirring often. This keeps the sauce from separating or thinning out too much when reheating your Easy Keto Beef Recipe!
Frequently Asked Questions About This Low Carb Mongolian Beef Recipe
I know you’ve got questions! When you’re dealing with takeout favorites that need a diet makeover, that’s totally normal. I’ve tried just about every trick in the book to keep these flavors spot on. Here are some things folks usually ask about making this delicious Easy Keto Beef Recipe!
Can I make this Low Carb Stir Fry ahead of time?
You totally can! This is a fantastic choice for meal prepping. I’d store the beef and sauce mixture separately from your cauliflower rice or noodles until you are ready to eat, just to keep everything crisper. It reheats beautifully, making it a perfect Weeknight Keto Dinner!
What is the best sweetener substitute for this No Sugar Mongolian Beef?
The standard recommendation for this No Sugar Mongolian Beef is granulated erythritol or monk fruit because they measure cup-for-cup like sugar. However, if you can find allulose, use it! It dissolves perfectly and doesn’t have that slight cooling effect some people notice with erythritol. Just measure carefully, since it converts differently.
Can I use cuts of beef other than flank steak?
Absolutely! While flank is my favorite texture-wise, sirloin or even skirt steak will work perfectly fine for this Keto Mongolian Beef. The key is to slice it thinly across the muscle fibers. That slicing technique matters way more than the specific cut for tenderness!
Estimated Nutritional Information for Low Carb Mongolian Beef Recipe
Now, I always tell people that these numbers are estimates because what you use (like low-sodium versus regular soy sauce, or which keto sweetener you chose) can change things! But, based on the core recipe serving four people, you get a massive hit of protein while staying super low in sugar. For one serving of this delicious Low Carb Mongolian Beef Recipe, expect roughly 350 calories, 38 grams of protein, and only 8 total carbs, with 2 grams of that being fiber! That’s what I call a win for your Weeknight Keto Dinner!

Low Carb Mongolian Beef
- Total Time: 30 min
- Yield: 4 servings
- Diet: Low Fat
Description
Make a quick, flavorful Mongolian Beef dish that fits a low-carbohydrate diet by replacing sugar and cornstarch with keto-friendly alternatives.
Ingredients
- 1.5 lbs flank steak, thinly sliced against the grain
- 1 tablespoon avocado oil or coconut oil
- 1 tablespoon sesame oil
- 4 cloves garlic, minced
- 1 tablespoon fresh ginger, grated
- 1/2 cup low-sodium soy sauce or tamari
- 1/4 cup water
- 1/4 cup erythritol or monk fruit sweetener
- 1 teaspoon xanthan gum (for thickening)
- 1/2 teaspoon black pepper
- 2 green onions, sliced (for garnish)
- 1 cup broccoli florets (optional addition)
Instructions
- Place the sliced steak in a bowl. In a separate small bowl, whisk together the soy sauce, water, sweetener, and black pepper. Set aside.
- Heat the avocado oil in a large skillet or wok over medium-high heat. Add the beef slices in a single layer, working in batches if necessary, and sear until browned on both sides. Remove the beef and set it aside.
- Reduce the heat to medium. Add the sesame oil to the skillet. Add the minced garlic and grated ginger. Cook for about 30 seconds until fragrant.
- If using broccoli, add it now and stir fry for 2-3 minutes until slightly tender.
- Return the beef to the skillet. Pour the reserved sauce mixture over the beef and vegetables. Bring the sauce to a simmer.
- In a very small bowl, mix the xanthan gum with 1 tablespoon of cold water to create a slurry. Slowly whisk this slurry into the simmering sauce. Continue stirring until the sauce thickens to your desired consistency, which should take less than one minute.
- Remove from heat immediately. Garnish with sliced green onions before serving over cauliflower rice or shirataki noodles.
Notes
- For a deeper flavor, use coconut aminos instead of soy sauce if you need to keep the dish gluten-free and soy-free.
- Xanthan gum is a powerful thickener; start with less than the recipe calls for if you are unsure of the amount needed for your preferred sauce thickness.
- You can substitute the flank steak with sirloin or skirt steak.
