Slow Cooker Mongolian Beef: Whole30, Paleo, Low Carb, GF - Whole Kitchen Sink (2024)

This easy slow cooker Mongolian beef is quick to throw into the crock pot, and is Whole30, Paleo, low carb and gluten-free. It only needs a handful of simple ingredients to make the sauce, along with flank steak, carrots, bell pepper and broccoli for the vegetables. This family friendly meal is perfect for dinner or for a healthy meal prep recipe!

Whole30 Mongolian Beef Ingredients

You’ll need coconut aminos, beef broth, toasted sesame oil, rice wine vinegar, arrowroot flour, for pantry ingredients, which I get for a discount on Thrive Market, but they’re all widely available at major grocery stores. You’ll also need minced garlic, ground ginger, carrots, green onion, bell pepper and broccoli.

There is an option to add honey to this recipe, which you would leave out for Whole30. This recipe is really flexible though in that you can also add whatever vegetables you have on hand or prefer. Sliced zucchini, water chestnuts, and mushrooms are favorites of ours to add. Just make sure to add them at the end with the other softer vegetables, being they won’t take very long to cook and you still want them a little crisp.

How To Prepare & Cook Slow Cooker Mongolian Beef

Making this recipe first starts by only cooking the beef, sauce, carrots and green onion in the crock pot. The Mongolian beef sauce ingredients get added into the slow cooker to cook the sliced steak in, and that’s going to be the majority of the cook time. You’ll start by coating the beef with the arrowroot and adding everything to the slow cooker except for the bell pepper and broccoli.

To keep the vegetables crisp in this Whole30 slow cooker recipe, you will add the veggies you’re using 30 minutes prior to the end of the cook time. Then the last step to thicken the sauce is optional. If you’d like a thicker sauce, you’ll mix 1.5 tablespoons of arrowroot flour with a few tablespoons of water (using a fork to dissolve), and then stirring that into the slow cooker. Repeat this process once more for a really thick sauce.

Garnish with additional green onion, sesame seeds or more red pepper chili flakes for an extra kick!

Serving Suggestions & Storing

This Whole30 Mongolian beef is great served on it’s own, or accompanied with vegetable rice like cauliflower or broccoli rice. If you eat rice, that is a great choice, too and we love having it with the sauce! We also like adding crisp green beans in with this as well.

You can store this recipe for up to 5 days in air-tight containers in the refrigerator. I wouldn’t freeze this recipe, being cooked steak doesn’t typically have a great texture once it’s thawed.
