Step‑by‑Step Instructions for Slow Cooker Mongolian Beef

Step 1: Prepare the Flank Steak
Start by trimming any excess fat from the flank steak and slicing it thinly against the grain. This will ensure that the meat remains tender and melts in your mouth. Aim for slices about a quarter-inch thick. Once sliced, set the beef aside while you mix the sauce, as this will allow it to absorb more flavor during cooking.

Step 2: Make the Sauce
In a medium bowl, whisk together the soy sauce, brown sugar, minced garlic, grated ginger, and cornstarch until smooth. This luscious mixture will create that delicious sweet-savory glaze you associate with your favorite Slow Cooker Mongolian Beef. Make sure the cornstarch is fully dissolved to avoid any lumps, ensuring a silky sauce.

Step 3: Combine Beef and Sauce in Slow Cooker
Place the sliced flank steak into the slow cooker, making sure to distribute it evenly. Pour the prepared sauce over the beef, ensuring every piece is thoroughly coated. Use a spatula or wooden spoon to gently toss the beef in the sauce, creating a fragrant base for your mouthwatering Slow Cooker Mongolian Beef.

Step 4: Cook the Beef
Cover the slow cooker with its lid and set it to cook on low for about 3 hours. During this time, the flavors will meld beautifully, and the beef will become fork-tender. Keep an eye on the clock; you want to ensure the meat doesn’t overcook, which would detract from its tenderness and juicy texture.

Step 5: Finalize and Serve
Once the cooking time is up, check the beef for tenderness, and give it a gentle stir to mix in the sauce. You’ll notice it’s become thick and glossy. Serve your Slow Cooker Mongolian Beef over a bed of cooked rice or noodles, garnishing with sliced green onions or sesame seeds for an added burst of flavor and visual appeal.

Expert Tips for Slow Cooker Mongolian Beef

Slice Against the Grain: Ensure the flank steak is sliced thinly against the grain to maintain tenderness. Thick slices can result in chewy meat that’s less enjoyable.
Soy Sauce Substitutions: For a gluten-free option, always choose a gluten-free soy sauce. This small switch allows everyone to enjoy your Slow Cooker Mongolian Beef.
Watch the Cooking Time: Set a timer to avoid overcooking. Check the meat for tenderness around the 3-hour mark; it should be fork-tender but not dry.
Add Heat: If you enjoy a spicy kick, feel free to add red pepper flakes or chili paste to the sauce. This adds a delightful layer of flavor to your dish.
Incorporate Veggies: For a nutritious boost, consider adding bell peppers, broccoli, or carrots into the slow cooker. They’ll cook beautifully alongside the beef without overwhelming the flavor.
Thickening the Sauce: If you prefer a thicker sauce, feel free to mix an additional teaspoon of cornstarch in some water and stir it into the slow cooker during the last 30 minutes of cooking.
