• 1/2 cup low sodium soy sauce: The salty umami backbone of the sauce, balancing the sweetness and adding complexity.
• 1/3 cup brown sugar: Essential for that signature caramelized sweetness Mongolian beef is famous for.
• 1/2 cup water: Helps create just the right sauce consistency to coat the beef and prevent drying.
• 1/2 cup green onions cut into 1/2 inch pieces: Adds a fresh pop of color and a mild onion bite to finish the dish.

How to Make Slow Cooker Mongolian Beef Recipe

Step 1: Prepare the Flank Steak

Begin by slicing your flank steak thinly against the grain to ensure every bite is tender. Toss the slices in cornstarch until they’re evenly coated. This step is crucial because the cornstarch not only protects the meat as it cooks but also helps thicken the sauce for that irresistible glossy finish.

Step 2: Assemble in the Slow Cooker

Place the cornstarch-coated flank steak directly into your slow cooker. Then add the toasted sesame oil, minced garlic, minced ginger, soy sauce, brown sugar, and water. Stir everything gently to make sure each piece of beef is bathed in all those flavorful ingredients, guaranteeing every mouthful bursts with that characteristic Mongolian beef taste.

Step 3: Slow Cook to Perfection

Cover your slow cooker and set it to cook on high for 2 to 3 hours or on low for 4 to 5 hours. The magic of this Slow Cooker Mongolian Beef Recipe happens here as the beef becomes tender and the sauce thickens into a luscious glaze. It’s so convenient since the slow cooker does the heavy lifting, letting you relax and anticipate the delicious meal ahead.

Step 4: Add the Final Touch

Just before serving, stir in the green onions. Their fresh, bright flavor cuts through the richness of the sauce and adds a lovely crunch and color contrast, making your dish visually inviting and pleasantly balanced in taste.
