Step‑by‑Step Instructions for Slow Cooker Mongolian Beef

Step 1: Prepare the Steak
Begin by slicing the flank steak thinly against the grain, ensuring each piece is uniform for even cooking. Aim for strips about ¼ inch thick; this promotes tenderness as it simmers. Once sliced, set the meat aside, allowing the natural juices to remain intact while you prepare the sauce.

Step 2: Mix Ingredients
In a medium bowl, blend together soy sauce, brown sugar, minced garlic, grated ginger, and water. Whisk until the sugar dissolves completely and the mixture is well combined. You’re looking for a sweet-savory balance that will enhance the Slow Cooker Mongolian Beef, so taste and adjust if necessary.

Step 3: Combine in Slow Cooker
Place the sliced flank steak directly into the slow cooker. Pour the prepared sauce mixture over the beef, ensuring every piece of meat is generously coated. Use a spatula to gently stir the contents, combining them well. This step is crucial for flavor infusion as the beef cooks.

Step 4: Cook
Cover the slow cooker with its lid and set it to cook on low for 3-4 hours or high for 1.5-2 hours. You’ll know the Slow Cooker Mongolian Beef is done when the steak is tender and easily shreds with a fork, releasing an irresistible aroma that fills your kitchen.

Step 5: Thicken Sauce (if desired)
If you prefer a thicker sauce, combine cornstarch with a couple of tablespoons of water in a small bowl. About 30 minutes before serving, stir this mixture into the slow cooker. Continue cooking uncovered, allowing the sauce to thicken, creating that glossy finish that perfectly coats the tender beef.

Step 6: Serve
Once cooked, serve the Slow Cooker Mongolian Beef over a bed of fluffy rice, soft noodles, or in crispy lettuce wraps for a fresh alternative. The dish looks inviting, with rich, dark sauce glistening, and it’s sure to make a wonderful impression on your family or guests.

How to Store and Freeze Slow Cooker Mongolian Beef

Reheating: Thaw in the fridge overnight before reheating. Warm it gently on the stovetop or in the microwave, adding a splash of water if the sauce is too thick.
