This incredible slow cooker Mongolian beef is bound to be a hit at home and is so easy to prepare.

Slow Cooker Mongolian Beef v2

You’re able to use a tougher cut of beef since you will be cooking it for a long time. By using a tough piece of beef, you will save money, and the result will still have a ton full flavor. Don’t worry about it being tough as by the time it’s finished cooking it will be very tender.

This dish as you would imagine is best to serve on top or next to some freshly cooked rice. For the best results make sure that you cook it on either the stove or in a rice cooker.

The leftovers of this dish are certainly worth keeping as they will reheat nicely. Just make sure you store it in an airtight container in the fridge. You could also freeze the leftovers as well. The dish will last for a few days in the refrigerator. However, I would be careful of keeping leftover rice as this can spoil quite fast especially if it’s at room temperature for too long.

Cooking Tips

  • As I mentioned above, make sure you use a tough piece of beef for the best results.
  • If you don’t like your food spicy, then leave the chili flakes out. The chili will give the dish a bit of heat but not enough to have you grabbing the nearest glass of water.
  • Try to avoid full sodium soy sauce as you may find the dish a bit too salty for your liking if you end up adding it. If regular soy is all you have, then half the amount and make up for the missing amount with some water.
  • For the best results use beef stock instead of just plain water. You can use powered (made per instructions), fresh, carton or any other type of beef stock that you have around. It doesn’t matter what type you go with so don’t worry about changing the amount you use.
  • If you love things on the sweeter side, then you can try increasing the amount of brown sugar to three-quarters of a cup.
  • You can leave hoisin out, but it’s an essential ingredient for getting the full experience of this dish.
