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?

MY LATEST RECIPES

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.

Calories: 330 kcal
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
  1. 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.

  2. To the bottom of slow cooker, add vegetable oil, garlic, ginger, water, soy sauce, brown sugar and Sriracha sauce.  Stir to combine.

  3. Add in coated flank steak and carrots and stir again until everything is coated in the sauce.

  4. Cover and cook on HIGH for 2-3 hours or on LOW for about 4 hours, until steak is cooked and tender.

  5. Serve over white rice and garnished with green onions and sesame seeds if desired.

  1. OMG SOOOOOOOO good thank you for sharing.

  2. Is there any reason not to just mix the cornstarch with the sauce ingredients, rather than coating the meat with it, since it all gets stirred together?

  3. Followed receipe…too sweet! Next time I will cut the sugar😁 I will try it again but will tweek the receipe. Is this suppose to be sweet?

  4. Hi,
    If I double, or even triple this recipe, will the cooking time be more or less the same? And it would just be yummier re-heated wouldn’t it….. 🙂

    • Hi Hege 🙂 I’ve never doubled or tripled the recipe, but I would assume the cooking time would be about the same, maybe a little bit longer. And yes, reheated leftovers taste great!

    • Hi there 🙂 I don’t provide full nutritional information for my recipes, as I’m not a nutritionist and don’t want to inadvertently pass out incorrect information.
