I love the tender flank steak that's a bit crispy and coated in a delicious + sticky sesame ginger sauce. It really can't be beat. Let's get to the in's and out's of the recipe!

Can I use regular erythritol instead of brown?

Yes, you can. I like the brown erythritol here as it adds a nice flavor to the sauce but any type of granulated sugar replacer will work just fine.

Can I use coconut aminos instead of tamari?

Yes, you can swap our the tamari for coconut aminos, please note that it will increase the carb just a bit so be sure to use your specific ingredients to calculate the nutrition.

What to serve with Keto Mongolian Beef...

Cauliflower rice, obviously. This is also great with our Keto Fried Rice, steamed veggies, or stir fried broccoli!

Can I use almond flour or coconut flour in place of whey protein isolate?

Yep, just swap out the same amount. I like the whey protein because it's not heavy and adds a light texture to the beef.

prep time: 45 Mcook time: 10 Mtotal time: 55 M


  • 1 lb flank steak cut into ¼” strips
  • 1 tablespoon tamari
  • 1 teaspoon toasted sesame oil
  • ¼ cup whey protein isolate
  • ½ cup neutral oil (avocado, algae, or refined coconut oil)
  • 1 tablespoon grated ginger
  • 4 garlic cloves, minced
  • ¼ cup tamari (or soy sauce if not gluten-free / or coconut aminos for soy free)
  • 3 tablespoons brown erythritol
  • 4 green onions, cut into 1” pieces
  • 2 teaspoon sesame seeds


How to cook Keto Mongolian Beef

  1. In a glass container with a lid combine the flank steak, tamari, and sesame oil. Toss to coat and refrigerate 30 minutes.
  2. In a small jar or bowl whisk together the ginger, garlic, tamari, and brown erythritol. Set aside.
  3. Heat the oil in a large 10.5” cast iron skillet over medium high heat (about 350° F).
  4. Place the whey protein isolate on a small plate. Working in batches to not overcrowd the pan, dredge each piece of steak through the protein then drop into the hot oil. Cook for about 2-3 minutes until crispy. Remove the beef from the oil with a large slotted spoon, and allow to drain on paper towels to remove excess oil.
  5. Drain all but 2 tablespoons of oil from the skillet. Pour in the sauce mixture and bring to a simmer. Once simmering add in the beef and green onions. Continue to cook for about 2 minutes until the onions have softened.
  6. Serve with cauliflower rice, broccoli rice, or Keto Fried Rice.
