Slow cooker Mongolian Beef

Chinese dishes are some of my favorites. We used to go out to our favorite restaurants at least once a week before I realized that it is so easy to make it right in the comfort of your own home. Some of our favorites have been our sweet and sour chicken recipe, our Ninja Foodi Orange chicken, and this easy to make slow cooker Mongolian beef recipe. 

Once you try this dish you will fall in love with the tender pieces of steak with the beautiful Mongolian flavor. This dish is the easiest way to enjoy your favorite Chinese dish, with hardly any mess and very little prep. 

Ingredients:

• 1 lbs. flank steak

How to Make Slow Cooker Mongolian Beef

• Thinly cut the flank steak against the grain, and then dice. Put the steak in a bowl.

• Season flank steak with salt and pepper to taste, and coat with cornstarch. Mix until well combined.

• Mince your ginger and garlic.

• At the bottom of the slow cooker, add the vegetable oil and then add the steak.
• Then add the garlic, ginger, brown sugar, sesame oil, soy sauce and water. Mix until well combined.

• Turn the slow cooker on 2.5 hours on high or 4-5 hours on low. Then stir when done cooking.
• Slice the scallion.

• Garnish the Mongolian beef with scallions and sesame seeds and serve over rice.

Tips Tricks and FAQs

• It can be difficult to cut flank steak, to ensure nice clean cuts, you may want to slightly freeze the meat for about 30 minutes. This makes the cutting much easier. 
• Be sure to slice your steak against the grain. This ensures tender pieces of meat. 
• We use low sodium soy sauce for this recipe. If you prefer you can also use regular soy sauce. This will make the dish a little more salty. If you do use this, I recommend omitting the salt. 
• If you cannot locate flank steak, you can also use skirt steak or hanger steak. As a last resort sirloin steak can work you will just need to slice it really thin.

What can I serve with my slow cooker Mongolian beef?
