I LOVE easy takeout copycat recipes!

Who doesn’t love easy weeknight dinners? That’s why the concept of takeout is so popular. 🙌 But this recipe for keto Crockpot Mongolian Beef comes together quickly so you don’t have to spend hours in the kitchen cooking and you can skip ordering out and save yourself some money too.

To keep things simple, you can make this in a Crockpot or Instant Pot. And stovetop actually works too! The flavor is amazing and is really just like takeout… but better, because you know everything that went into it! It even makes great leftovers as well. 🥡

Your family won’t even believe it’s keto!

This keto Crockpot Mongolian Beef is adapted from our Hip2Save Instant Pot Mongolian Beef recipe. To make it keto, we switched out the brown sugar for a keto brown sweetener (I love Swerve) and used xanthan gum in place of corn starch as the thickener. We also served it over cauliflower rice instead of traditional rice.

Tips for making the best keto Crockpot Mongolian Beef:

    • You can use flank steak or a sirloin steak to make this recipe. Flank steak is more traditional, but sirloin steaks generally tend to be more affordable.
    • If you’re running short on time, you can cook this in a large skillet and skip the Crockpot. If opting for the skillet method, add the sauce to the meat in the skillet after you sear it and let the meat cook for about 10-15 minutes. Then sprinkle in the xanthan gum and stir in the green onions.
    • To make this recipe in your Instant Pot, add oil to the bottom of the pot and turn the Instant Pot to sauté. Brown the steak in the oil, and note that you may need to do this in batches. Then add the sauce, close the lid, and set the time for 12 minutes (manual) on HIGH. Carefully vent when finished to release the pressure. Turn the Instant Pot back on sauté function and sprinkle in the xanthan gum to thicken.
    • Broccoli also makes a great addition to this meal if you’re looking to add in more veggies!
    • If you want to add some heat, try adding in 1/4 teaspoon red pepper flakes or top with Sriracha.

My Hip sidekick Jen tried out this Mongolian beef recipe and here’s what she had to say:

“This was a HUGE hit in our house and it’s surprisingly so fast to throw together! The meat is really tender and savory. This recipe is super versatile for people who are not eating keto. My non-keto eaters loved this because they could put theirs over regular rice while I used cauliflower rice. Another plus is that this meal is really filling and makes a lot! It’s hard to keep everyone in the family happy but we all loved it!”
