Why You’ll Love This Recipe
If you love Mongolian Beef, this recipe is just as delicious as your favorite take out. It is so easy to make with a slow cooker, and the beef comes out perfectly tender and delicious. As an added bonus, your kitchen will smell amazing while it cooks.

Ingredients
- sirloin steak, sliced thinly
- cornstarch
- olive oil
- onion, sliced thin
- green onions, sliced in 1 inch pieces
- garlic, minced
- soy sauce
- water
- brown sugar
- ginger, minced
- sesame oil

How to Make Slow Cooker Mongolian Beef
- Slice the sirloin steak into strips. Coat the sliced beef in cornstarch and allow to rest for 10 minutes.
- Heat oil in pan and add steak. Cook until lightly browned, 3-5 minutes. Although this step takes a few minutes, it adds flavor and texture to the dish. This step can be skipped, but I recommend trying it.
- Mix together soy sauce, sesame oil, water, brown sugar, minced garlic, and minced ginger to make the sauce.
- Place onion, steak, green onions and sauce mixture into slow cooker.
- Cook on low for 4 hours, until meat is cooked through and tender.

Add a little sliced green onion and toasted sesame seeds for garnish and serve with rice.

Looks good! I make something very similar to this with pot roast in the slow cooker without the corn starch. After the pot roast is ready, I make a gravy with the liquids in a pan on the stove by adding some flour. My family loves it!
Sandy says
I don’t really see the point of the slow cooker for this. You have to dirty up a skillet to cook the meat, and basiclly let it sit in the sauce in the slow cooker for 4 hours. The non slower cooker method is quicker, you spend a few minutes cooking the sauce in the skillet.
Leigh Anne says
Sandy, The meat gets much more tender when cooked in a slow cooker than it does if you just stir fry it up in a pan but it definitely could be done the way you describe too. Whatever works best for you.
Liz says
Thank you Leigh Anne for the nice recipe. Have a good day and week.
Mary says
I’d love to try your recipe but notice your sauce ingredients include 1 Tbsp. minced garlic and also 1/2 tsp. minced garlic. Should one of these be a different ingredient?
Leigh Anne says
Mary, good catch! That should be 1/2 tsp minced ginger. I have fixed the recipe. The garlic amount is correct.
Sheri says
It looks like the two measurements for garlic are showing up instead of the ginger
you mentioned. Looks like a good recipe.
