Easy Mongolian Beef Slow Cooker Recipe

This Easy Slow Cooker Mongolian Beef is a family-friendly dish with tender, thinly sliced flank steak soaked in a sweet and savory sauce. Just toss it in your crockpot for a flavorful meal that’s ready in 4 hours.

  • Total Time: 4 hours 10 minutes
  • Yield: 8 servings 1x

Ingredients

Units Scale
  • 1.5 pounds of Flank Steak
  • 1/4 cup of Corn Starch
  • 1 medium Onion, sliced thin
  • 3/4 cup of Soy Sauce
  • 2 tablespoons of Sesame Oil
  • 1/2 cup of Sugar or Monk Fruit sweetener
  • 3/4 cup of Water
  • 3 cloves of minced Garlic
  • 1 tablespoon of Minced Fresh Ginger
  • 1/4 teaspoon Red Pepper Flakes or 1 teaspoon of Sriracha
  • Garnish with sliced Green Onions and Sesame Seeds.

Instructions

  1. Slice the Beef: Cut the flank steak into thin slices, about 1/4 inch thick. Pro tip: If the beef is slightly frozen, it’s way easier to slice!
  2. Coat the Beef: Put the sliced beef and cornstarch in a large ziplock bag. Seal it tight, then shake and mix until all the beef is coated.
  3. Add Onions: Place onion slices at the bottom of your slow cooker.
  4. Layer the Beef: Spread the coated beef slices on top of the onions.
  5. Make the Sauce: In a medium bowl, mix soy sauce, sesame oil, sugar (or Monk fruit sweetener), and water. Whisk until it’s smooth. Add minced garlic, minced ginger, and a pinch of red pepper flakes or a dash of sriracha for a little kick (skip if you want it mild).
  6. Pour and Cook: Pour the sauce over the beef in the slow cooker. Cover and cook on low for 4 hours.
  7. Check Halfway: After 2 hours, quickly lift the lid (don’t keep it off for more than a minute—it takes 30 minutes to heat back up!) and make sure the beef is covered in sauce. Stir gently if needed.
  8. Add Veggies (Optional): If you want to add bell peppers or broccoli, toss them in 1 hour before the cooking time is up.

  9. Serve and Enjoy: When the beef is done, it’ll be tender and full of flavor. Garnish with sliced Green Onions and Sesame Seeds. 

    Serve it with rice or your favorite side!

Notes

  1. Keep the lid on as much as possible to hold in the heat.
  2. Adjust the red pepper flakes or sriracha to make it as spicy or mild as your family likes.
  3. Slightly frozen beef is easier to slice, so pop it in the freezer for 20–30 minutes if it’s too soft.
