And not only is this meal super easy to prepare, but it is soooooo good! The beef is covered in a delicious, tangy, flavorful sauce that is not too spicy, but just right. This crock pot recipe actually tastes just like a meal you would get from an Asian restaurant!

This crockpot Mongolian Beef pairs well with steamed rice. I usually serve it with rice or lo mein noodles.  You could pair it with your favorite vegetables as well.

Instructions

Cut your flank steak into thin slices, making sure you slice against the grain. Then dice into smaller pieces. Place the steak into a bowl.

Season flank steak with salt, pepper and onion powder, and coat with cornstarch. Stir until combined, then set aside. Discard any leftover cornstarch. 

Mince both your ginger and garlic.

At the bottom of your slow cooker add the vegetable oil and then the steak.

In a bowl, mix the garlic, ginger, brown sugar, sesame oil, soy sauce and water until well combined.  Gently pour over the steak. 

Cover and cook steak on High for 2-3 hours or on Low for 4-5 hours.

About 20 minutes before serving, whisk together 2 tablespoons of cornstarch with 2 tablespoons of cold water. Add this mixture to the slow cooker and stir. Cook for an additional 20 minutes or until the sauce thickens.

Garnish the Mongolian Beef with scallions and sesame seeds. 

Serve over a bed of rice, noodles, or your favorite steamed vegetables. Enjoy!
