How to Make Slow Cooker Mongolian Beef

Step 1: Prep the beef

Begin by thinly slicing your beef against the grain. This will ensure tenderness after slow cooking. Set it aside while you prepare the sauce.

Step 2: Mix the sauce

In a bowl, combine soy sauce, brown sugar, minced garlic, and grated fresh ginger. Stir until the sugar dissolves completely, creating a sweet and savory marinade.

Step 3: Combine ingredients in slow cooker

Place the sliced beef into the slow cooker, pour the sauce mixture over the top, and add a splash of water or broth to keep things moist. Save some green onions for garnish.

Step 4: Cook low and slow

Cover and cook on low for 4 to 6 hours, or until the beef is tender and has absorbed the sauce. Resist the urge to open the lid too often so the heat stays consistent.

Step 5: Thicken the sauce

About 20 minutes before serving, mix cornstarch with cold water and stir it into the slow cooker. Turn the heat to high to help the sauce thicken and become luscious and glossy.

Step 6: Garnish and serve

Sprinkle the reserved green onions over the top and serve hot over steamed rice or noodles for a complete meal.

Pro Tips for Making Slow Cooker Mongolian Beef

• Slice beef thinly: Use a sharp knife and cut against the grain to ensure tenderness.
• Don’t skip fresh aromatics: Fresh garlic and ginger dramatically elevate the flavor compared to powders.
• Keep the lid closed: Avoid lifting the slow cooker lid too often to maintain steady cooking temperature.
• Adjust sweetness: Taste the sauce before cooking and tweak sugar levels to your liking.
• Use cornstarch slurry last: Adding cornstarch toward the end helps the sauce thicken perfectly without becoming gummy.
