How to Make Slow Cooker Mongolian Beef:

Embark on this culinary adventure with a step-by-step guide to creating the perfect Slow Cooker Mongolian Beef. While browning the beef in a frying pan before slow cooking is an optional step, it elevates the dish by locking in the steak’s juices, enhancing the overall flavor. For those who prefer a crunchier texture, adding peppers and onions towards the end is an excellent tweak. Spice enthusiasts can rejoice by incorporating a pinch of red pepper flakes into the sauce, giving the dish an extra kick.


Delve into the simplicity of Slow Cooker Mongolian Beef with its minimal yet impactful ingredients. The star of the show is the flank steak, with sirloin serving as a suitable substitute (avoid stew meat). Cornstarch acts as a natural tenderizer, while garlic, soy sauce, and water contribute to the rich, saucy goodness. The dance of flavors continues with the addition of brown sugar and the crunch of grated carrots. Optionally, garnish with green onions and sesame seeds for a visually stunning and flavorful finish.

Tips and Variations:

Transform this Mongolian masterpiece into a family favorite with a few tweaks and variations. Optimal slicing of the flank steak against the grain ensures tenderness, with the thickness maintained at about 1/4 inch. Introduce additional textures and nutritional elements by stirring in roasted broccoli, green beans, or red bell peppers. Short on time? Fear not – convert this slow cooker wonder into an Instant Pot marvel by following simple sauté and pressure-cooking steps.

Preserving the Culinary Delight:

Leftovers are a blessing in disguise, as Mongolian beef reheats beautifully. Store it in the refrigerator for up to 4 days in a sealed container, or freeze for up to 4 months in an airtight container or freezer ziplock bag. Thaw in the refrigerator before reheating, providing a quick and satisfying meal for any occasion.


Are There Substitutes for Flank Steak?

Absolutely! While flank steak is the preferred choice, skirt steak, hanger steak, or thinly sliced sirloin steak can be delightful alternatives.

Why is it Called Mongolian Beef?

Originating in Taiwan, Mongolian beef gained popularity in the region where the first Mongolian restaurants emerged. This style of cuisine became synonymous with dishes like Slow Cooker Mongolian Beef, explaining its intriguing name.
