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

Step 1: Prepare the Steak
Start by slicing the flank steak against the grain into thin strips, about 1/4 inch thick. This ensures tenderness after cooking. Aim for uniform slices for even cooking. Set aside while you gather the remaining ingredients, as this will prep the main star of your Easy Slow Cooker Mongolian Beef.

Step 2: Combine Ingredients
In a large mixing bowl, combine the sliced steak with grated ginger, minced garlic, soy sauce, brown sugar, and sesame oil. Mix everything well until the steak is evenly coated in the flavorful marinade. Letting it sit for at least 30 minutes, or overnight, allows the flavors to penetrate the meat, enhancing your Slow Cooker Mongolian Beef.

Step 3: Transfer to Slow Cooker
Pour the marinated beef mixture into your slow cooker, spreading it out evenly. Ensure the sauce, coated around the steak, sits at the bottom. This allows the meat to absorb the delicious flavors while it cooks. Set your slow cooker to low heat, preparing for a comforting meal to simmer!

Step 4: Cook Low and Slow
Cover the slow cooker and cook on low for 6-7 hours or on high for 3-4 hours. The beef should be tender and easily pull apart with a fork when cooked properly. Resist the urge to uncover the lid too often, as this will release steam and potentially increase cooking time for your Easy Slow Cooker Mongolian Beef.

Step 5: Thicken the Sauce
About 30 minutes before you’re ready to serve, mix the cornstarch with a couple of tablespoons of water until smooth. Stir this mixture into the slow cooker and gently mix to combine. This step will ensure your sauce thickens beautifully, clinging to the tender beef for a rich consistency.

Step 6: Serve
Once cooked, carefully plate the Slow Cooker Mongolian Beef, drizzling the thickened sauce over the meat. Garnish with freshly sliced green onions for an added pop of flavor and color. Serve immediately over fluffy rice or noodles for a delightful meal that showcases the warming aromas of garlic and ginger.

Expert Tips for Slow Cooker Mongolian Beef

Marinate Longer: Allow the steak to marinate for at least 30 minutes, or even overnight, to deepen the flavors of your Slow Cooker Mongolian Beef.
