The easiest way you can make a Mongolian beef recipe! The beef gets meltingly tender in the slow cooker and the sauce becomes incredibly silky, with great spicy/sweet flavors!

All of the amazing spicy/sweet flavors of Mongolian beef, but in an incredibly easy slow cooker meal with just 10 minutes of prep.  This is the Mongolian beef recipe for the busiest of people!

Who here loves Chinese take-out style meals?  *raises hand frantically*  I love all the bold flavors, great sauces, and how quickly things cook!  One thing I don’t like though, is how hectic it can be to cook take-out style meals at home.  The nature of a stir fry is that things cook really quickly, which means you have to have every component in the recipe ready to go… and things can STILL get stressful right?

Slow Cooker Mongolian Beef Recipe

The main thing I love so much about this Mongolian beef recipe is that unlike some slow cooker meals, it’s made entirely in the slow cooker, with no extra steps to take.  No browning the meat, no broiling… just adding all the ingredients, turning on the slow cooker and walking away.  Simply amazing.

And this meal is certainly not short on flavor!  The garlic and ginger bring plenty of classic Mongolian beef flavor, and combined with sweet/heat combination of brown sugar and Sriracha sauce… it’s a powerhouse of amazing flavors!

WHAT SPICES ARE USED IN MONGOLIAN BEEF

Typically Mongolian beef is made with soy sauce, brown sugar, ginger, and garlic.  I like mine to be a little sweet and spicy, so I add some Sriracha to it as well.

WHAT KIND OF BEEF DO YOU USE IN MONGOLIAN BEEF?

Most recipes, including both this slow cooker version and my classic recipe, use flank steak.  I’ve also heard of people using sirloin steak as well.

TIPS AND TRICKS FOR MAKING THIS SLOW COOKER MONGOLIAN BEEF RECIPE:

  • Slice your flank steak against the grain.  As you’re looking at the beef, you’ll see lines, like the grain on a piece of wood.  You want to slice it across those lines, not alongside them.  Doing this ensures an incredibly tender piece of beef.
  • The carrots are optional, but add a great texture!
  • Add the Sriracha to your tastes.  I like this recipe to have a little heat to balance out the sweetness.
  • To make this a complete meal, add some steamed broccoli and rice!

My original classic Mongolian beef recipe has done so well, with so many of you emailing with rave reviews, so I knew I didn’t want to deviate from those flavors.  To adapt the sauce to work well in a slow cooker I added some extra soy sauce and water.  Also, since there’s no marinating with this recipe, I added some extra ginger and Sriracha to boost the flavors.

HELPFUL TOOLS:

  • 4 quart slow cooker – My absolute favorite slow cooker!

The easiest way you can make a Mongolian beef recipe! The beef gets meltingly tender in the slow cooker and the sauce becomes incredibly silky, with great spicy/sweet flavors!

Ingredients

  • 1 1/2 lbs thinly sliced flank steak (1/4 inch thick)
  • 1/4 cup cornstarch
  • 1 Tbsp vegetable oil
  • 3-4 cloves garlic, minced
  • 2 tsp fresh ginger, minced
  • 3/4 cup water
  • 3/4 cup reduced sodium soy sauce
  • 3/4 cup light brown sugar, packed
  • 1 - 2 tsp Sriracha sauce (can substitute with red pepper flakes or cayenne instead - in whatever amount you prefer)
  • 1 cup shredded carrots
  • 4-6 green onions, thinly sliced
  • sesame seeds, for garnish

Instructions

  • Add sliced flank steak and cornstarch to a large resealable plastic bag.  Close and shake to coat well.  This can be done in a large mixing bowl as well, but I find it's less messy to do in a bag.
  • To the bottom of slow cooker, add vegetable oil, garlic, ginger, water, soy sauce, brown sugar and Sriracha sauce.  Stir to combine.
  • Add in coated flank steak and carrots and stir again until everything is coated in the sauce.
  • Cover and cook on HIGH for 2-3 hours or on LOW for about 4 hours, until steak is cooked and tender.
  • Serve over white rice and garnished with green onions and sesame seeds if desired.

  1. Slice your flank steak against the grain.  As you’re looking at the beef, you’ll see lines, like the grain on a piece of wood.  You want to slice it across those lines, not alongside them.  Doing this ensures an incredibly tender piece of beef.

    I used Flat Iron Steak because I couldn’t find flank steak. I have it in the slow cooker ad I write this. Hope it will be ok and that it is tender..

    This was so yummy. I had to use skirt steak in place of flank because the flank steak was $35 at my grocery store (for comparison, skirt steak was $8), and it came out perfectly. Very tender and flavorful!
