Step‑by‑Step Instructions for Slow Cooker Mongolian Beef

Step 1: Prepare the Flank Steak
Begin by slicing the flank steak into thin strips against the grain, ensuring tenderness when cooked. Aim for uniform pieces approximately half an inch wide to promote even cooking. Once sliced, set the beef aside while you prepare the sauce; this way, you’re ready for the next steps without any delay.

Step 2: Mix the Sauce
In a medium bowl, whisk together soy sauce, brown sugar, minced garlic, and grated ginger until fully combined. The mixture should be a smooth, glossy liquid that highlights the rich flavors of the soy and the sweetness of the sugar. This will form the luscious sauce that will coat the flank steak during the slow cooking process.

Step 3: Combine Beef and Sauce
Transfer the sliced flank steak into the slow cooker and pour the prepared sauce over the top. Use a spatula to gently coat each piece of beef, ensuring that they are evenly submerged in the aromatic sauce. This step is crucial for infusing the flavors throughout the meat as it cooks in your slow cooker.

Step 4: Set the Cooking Time
Cover the slow cooker with its lid and set it to cook on low for 3 hours, or on high for 1.5 hours. This gentle cooking method allows the flavors to meld together while the beef becomes beautifully tender. Keep an eye on the clock; you’ll know it’s ready when the meat can easily be shredded with a fork.

Step 5: Thicken the Sauce
Once the cooking time is complete, carefully remove the beef and set it aside on a plate. In a small bowl, mix cornstarch with a little water to create a slurry. Stir this mixture into the sauce left in the slow cooker, then cover and cook on high for an additional 30 minutes. This step thickens your sauce, creating that delightful glossy finish.

Step 6: Serve
Finally, return the tender beef to the slow cooker, stirring gently to coat every piece in the thickened sauce. Allow it to warm through for another few minutes before serving. Present your Slow Cooker Mongolian Beef over rice, noodles, or in lettuce wraps for a delicious, satisfying meal that’s sure to impress!
