How to Make Slow Cooker Mongolian Beef

Step 1: Prepare the Beef

Slice your beef thinly across the grain to ensure tenderness and quick cooking. Toss these strips in cornstarch briefly to help the sauce stick and give the beef a slight crisp edge once cooked.

Step 2: Mix the Sauce

Whisk together soy sauce, brown sugar, minced garlic, grated ginger, and a splash of water or broth. This mixture will create that signature balance of sweet and savory that defines Mongolian Beef.

Step 3: Layer Ingredients in Slow Cooker

Add the beef strips into the slow cooker, then pour the sauce evenly over the top, ensuring every piece is coated. You don’t need to stir just yet — the slow cooker will do the work.

Step 4: Cook Low and Slow

Set your slow cooker on low for about 4 to 6 hours. This slow and gentle heat allows flavors to meld perfectly and the beef to become melt-in-your-mouth tender without drying out.

Step 5: Finish and Garnish

About 15 minutes before serving, stir the beef gently, sprinkle over sliced green onions, and add any optional vegetables if desired. Let those flavors mingle just before you plate.

Pro Tips for Making Slow Cooker Mongolian Beef

• Use thin beef slices: It’s key for tenderness and quick cooking in the slow cooker environment.

• Adjust sweetness: Taste the sauce before cooking and tweak sugar levels to your preference.
• Layer ingredients strategically: Place beef at the bottom for best saucing or in the middle if adding vegetables on top.
• Resist over-stirring: Let the slow cooker do its magic for the best texture and flavor development.
