Ingredients
Scale
Main Ingredients
- 1 ½ pounds flank steak
- ¼ cup cornstarch
- 2 tablespoons olive oil
- 1 teaspoon garlic, minced
- ¾ cup soy sauce
- ¾ cup water
- ¾ cup brown sugar
- 1 cup carrots, grated
For Garnish
- Green onions, sliced
- Sesame seeds
Instructions
- Prepare the beef: Cut 1 ½ pounds flank steak into thin strips. Place the beef strips in a ziplock bag with ¼ cup cornstarch, then shake the bag well to evenly coat the beef with cornstarch.
- Make the sauce: In a medium bowl, whisk together 2 tablespoons olive oil, 1 teaspoon minced garlic, ¾ cup soy sauce, ¾ cup water, and ¾ cup brown sugar until the sugar is dissolved and the mixture is well combined.
- Combine ingredients in slow cooker: Add the grated carrots and the coated flank steak strips to the slow cooker. Pour the prepared sauce over the beef and carrots, then gently stir everything to ensure all pieces are covered in sauce.
- Cook the beef: Cover the slow cooker and cook on high heat for 2 to 3 hours or on low heat for 4 to 5 hours, until the beef is tender and the sauce has thickened slightly.
- Serve and garnish: Serve the Mongolian beef hot over steamed rice. Garnish generously with sliced green onions and a sprinkle of sesame seeds for added flavor and texture.
Notes
- For best texture, slice the flank steak thinly against the grain.
- Adjust brown sugar quantity for desired sweetness.
- Serve over jasmine or basmati rice for authentic pairing.
- Can substitute flank steak with sirloin or skirt steak if preferred.
- Green onions and sesame seeds add a fresh and nutty finish—don’t skip the garnish.
