Slow Cooker Mongolian Beef Ingredients

For the Beef
• Flank Steak – This cut becomes melt-in-your-mouth tender and is perfect for slow cooking; substitute with sirloin or chuck roast if needed.

For the Sauce
• Soy Sauce – Provides that essential umami flavor base; opt for gluten-free soy sauce if you’re keeping it gluten-free.
• Brown Sugar – Adds the perfect level of sweetness to balance the salty soy sauce; try coconut sugar for a lower glycemic alternative.
• Garlic – Fresh minced garlic enhances the dish’s aromatic qualities and depth of flavor; dried garlic powder works in a pinch.
• Ginger – Adds a fresh, spicy kick to the sauce; fresh ginger is best, but ground ginger can be a convenient substitute.
• Cornstarch – Used to thicken the sauce for a silky finish; you can skip it if you prefer a thinner sauce.
• Water – Helps create a cooking liquid that prevents the beef from drying out during slow cooking.

Step‑by‑Step Instructions for Slow Cooker Mongolian Beef

Step 1: Prepare Ingredients
Begin by slicing the flank steak thinly against the grain; this ensures maximum tenderness. While prepping, mince the garlic and ginger finely, allowing their flavors to release. Gather your ingredients and have your slow cooker ready to create the delightful Slow Cooker Mongolian Beef.

Step 2: Mix Sauce
In a large mixing bowl, combine ½ cup soy sauce, ½ cup brown sugar, the minced garlic, and ginger. Sprinkle in 1 tablespoon of cornstarch, stirring thoroughly until the mixture is well-blended and smooth. This thick, fragrant sauce will be the heart of your Slow Cooker Mongolian Beef.

Step 3: Combine in Slow Cooker
Place the sliced flank steak into the bottom of the slow cooker, spreading it out for even cooking. Pour the prepared sauce mixture over the beef, ensuring all pieces are adequately coated. This will help infuse the flavors deeply, enhancing the final dish’s taste.

Step 4: Cook
Cover and set your slow cooker to low for 4-6 hours or high for 2-3 hours. The key here is to allow the beef to absorb the sauce and become tender. You’ll know it’s ready when you can easily shred the beef with a fork, indicating it’s cooked to perfection.

Step 5: Finish
Once the cooking time is complete, remove the lid and stir the beef and sauce together to combine. This last step helps ensure each piece of beef is coated in the delicious sweet-savory sauce, making your Slow Cooker Mongolian Beef irresistible and ready for serving.
