Step‑by‑Step Instructions for Easy Slow Cooker Mongolian Beef

Step 1: Prepare the Steak
Begin by slicing the flank steak against the grain into thin strips, about 1/4-inch thick, to ensure tenderness. Aim for uniform pieces, which will cook evenly in the slow cooker. This preparation only takes about 10 minutes and sets the foundation for flavorful Slow Cooker Mongolian Beef.

Step 2: Combine Ingredients
In a large mixing bowl, combine the sliced beef with grated ginger, minced garlic, soy sauce, brown sugar, and sesame oil. Toss the mixture until the steak is well-coated with the aromatic marinade. This step enhances the flavors and should take about 5 minutes; the mixture will have an appealing glossy appearance.

Step 3: Transfer to Slow Cooker
Pour the beef mixture into your slow cooker, spreading it out evenly across the bottom. Ensure the pieces are well-distributed for consistent cooking. Set the slow cooker on low heat to begin the magic of slow cooking, allowing it to work its wonders and permeate with deep flavors over the next several hours.

Step 4: Cook
Cover the slow cooker and cook the beef on low for 6-7 hours or on high for 3-4 hours. You’ll know it’s ready when the beef is fork-tender and easily shreds apart. The aroma wafting through your kitchen will signal that your Easy Slow Cooker Mongolian Beef is almost ready to serve!

Step 5: Thicken the Sauce
About 30 minutes before serving, mix cornstarch with a little water to create a slurry. Stir this mixture into the slow cooker to thicken the sauce, ensuring it clings beautifully to the beef. The sauce should start to bubble slightly, at which point it will become glossy and rich, signifying it’s ready for the final serving.

Step 6: Serve
Once the sauce has thickened, gently scoop the Mongolian beef onto plates or bowls. Drizzle the thickened sauce generously over the meat, and for a delightful garnish, sprinkle with sliced green onions. This final touch not only adds a pop of color but also a fresh crunch to your delicious dish!
