Crock Pot Mongolian Beef Recipe:

We love getting Chinese take out but it really gets expensive for our family. Now, we make this instead and save a ton of money while enjoying a really great dinner. The flank steak is cooked with soy sauce, brown sugar and ginger and it taste better then what you would get at a Chinese restaurant.

The best part is the crock pot does all the work so that dinner time is a breeze. Crock pot Mongolian Beef is so tasty and really satisfies that craving for Chinese food.

You can also make Instant Pot Mongolian Beef Recipe. It is just as good but ready in 20 minutes! Perfect for the nights you forgot to plan for dinner. If you love this recipe, see 35 Easy Shaved beef recipes for another easy meal.

We love our Crock Pot!

We love crock pots around here. I have several and they get tons of use. If you are in the market for something new, I really love my Instant Pot Aura Multi-Cooker. The nice thing about this is you can brown the meat right in the same slow cooker!

Cooking the meat in the crock pot saves me so much time as I only have one pan to clean! It has become of my favorite kitchen appliances.

I also really like this crockpot as well.  My favorite feature is that you can lock the lid down. This is awesome for when you need to take the crockpot to a family get together or party!

Another favorite is this programmable crock pot  for when I am am not at home all day. I love coming home to a nice meal ready and waiting!

Mongolian Beef makes a great stir fry!

Did you know that you can also make this recipe as a stir fry? That is why I love this recipe! It is great in the instant pot, crock pot and even on your stove top!

You use the same ingredients you just cook it in a Wok or a iron skillet. Just start with some olive oil and add the flank steak and the remaining ingredients. Dinner will be done in about 30 minutes.

We love making a stir fry at our house! It is a great way to use up vegetables that you have leftover from the week and make a great meal.

Why is it called Mongolian Beef?

This dish actually originated in Taiwan and the name refers to Mongolian BBQ, a style of food and not a place. This style of food is very popular in Taiwan and is where the first Mongolian restaurants starting opening up.

This type of beef is a Chinese-American dish and is very popular at Chinese restaurants. It is tenderized slices of meat that is simmered together in a sweet and savory sauce.

What to serve with Mongolian Beef?

We love to serve Mongolian Beef over rice and garnish with the green onions and sesame seeds. Did you know that you can also cook rice in the slow cooker?  I like to cook a ton of rice in my crock pot and then freeze rice for recipes like this one. This way I always have some cooked rice on hand for recipes that require it or for a quick side dish in not time at all.

To complete our meal, we like steamed broccoli in the microwave for a quick and easy side dish. It is so simple and really delicious with Mongolian Beef.

Have you roasted broccoli in the oven? It has become one of my favorite side dishes and the broccoli comes out perfectly! You might also like this amazing oven roasted parmesan asparagus recipe

Are there any substitutes for Flank Steak?

We generally use flank steak but you can try using round steak or skirt steak.  I like to use what I can purchase on sale at the grocery store or already have in the freezer.

The great thing about this recipe is how versatile it is. It is easy to modify for what you have on hand and this really helps your budget. By cooking like this, it really helps me to save money on groceries. It is a huge help to our budget.

If you do not prefer red meat, you can also make this with chicken instead.  Follow the same process and slice the chicken breasts or thighs to make a delicious instant pot Mongolian chicken meal.  

Other Variations:

If you have a gluten allergy, coconut aminos can be used instead of the soy sauce in this recipe.  Coconut Aminos still has that great soy sauce taste but is a gluten free product so you can still enjoy this great Mongolian beef recipe in the crock pot. You can also try some hoisin sauce.

If you prefer spicy dishes, you may also add red pepper flakes to this beef dish to add some kick to this Mongolian beef recipe.

This recipe calls for shredded carrots and I love to use this vegetable grater to shred my carrots quickly.  However, if you do not like carrots, you can use broccoli instead to make a delicious instant pot beef and broccoli recipe for your family to enjoy.

    We really liked it but I think I will reduce the sugar next time. I also added an extra cup of boiling water near the end to thin the sauce a bit

  2. Jen Rice says:

    Oh my goodness! My family loves beef but I only eat it occasionally. This recipe was very easy to make and it was delicious! I went back for seconds!

  3. Marsha Schoolcraft says:

    My family LOVES this one!

  4. Jill M DeLapp says:

    This looks really good. My family likes a lot of sauce with dishes like this. Should I double the wet ingredients, or is there a lot of sauce when it’s cooked?

  5. Carrie says:

    Sorry about that. This was a typo. I did not use ginger in this recipe and I have updated the post. Thank you.

  6. Carrie says:

    Yes, I would cook on high pressure for 20 minutes with a quick release. Let me know how it turns out. Thank you.

  7. Valerie says:

  8. Liesl Nielsen says:
