How to Make Slow Cooker Mongolian Beef

1. Make the Sauce
   In a slow cooker, combine the soy sauce, brown sugar, beef broth, garlic, ginger, and black pepper. Stir well until the sugar dissolves completely.

2. Add the Beef
   Add the sliced flank steak to the slow cooker. Make sure to coat the beef evenly in the sauce for maximum flavor.

3. Cook Low and Slow
   Cover and cook on low for 6-8 hours or until the beef is tender and easily shreds with a fork.

4. Thicken the Sauce
   In a small bowl, mix the cornstarch with a little water to create a slurry. Stir this into the slow cooker and cook for an additional 30 minutes, ensuring the sauce thickens nicely.

5. Serve and Garnish
   Serve the Mongolian beef over rice and garnish with the sliced green onions for a burst of freshness.

Tips for Success

• Slice Against the Grain: When cutting the flank steak, always slice against the grain to ensure it remains tender.
• Don’t Skip the Slurry: Adding the cornstarch slurry is crucial for achieving the desired sauce thickness, so don’t skip this step.
• Timing is Key: For best results, set your slow cooker for the right amount of time according to how tender you want the beef.
• Adjust the Sweetness: If you prefer a less sweet flavor, reduce the brown sugar by a couple of tablespoons.

Easy Variations

• Substitute Protein: Swap the flank steak for chicken breast or tofu for a different protein source.
• Add Vegetables: Toss in bell peppers or broccoli during the last hour of cooking for added nutrition and flavor.
• Spicy Kick: Add a teaspoon of red pepper flakes to the sauce for a spicy version of the dish.
• Gluten-Free Option: Use tamari sauce instead of soy sauce for a gluten-free version.

What to Serve with Slow Cooker Mongolian Beef

• Steamed Rice: The perfect base to soak up the delicious sauce.
• Vegetable Fried Rice: For added flavor and texture, this is a great pairing.
• Sautéed Greens: Bok choy or spinach bring a fresh element that balances the richness of the beef.
• Egg Rolls: A fun side option that complements the Asian flavors of the dish.

Storage and Reheating

• Refrigerator Storage: Store any leftovers in an airtight container in the fridge for up to 4 days.
• Freezer Storage: This dish can be frozen for up to 3 months. Just ensure it cools completely before freezing.
• Reheating: Reheat gently on the stovetop or in the microwave. If reheating from frozen, it’s best to thaw overnight in the fridge before warming.
• Preserve Texture: Reheat it on low to avoid overcooking the beef again, which could make it tough.

Common Mistakes to Avoid

• Overcooking the Beef: While slow cooking is forgiving, be careful not to cook longer than necessary as this can dry out the meat.
• Underseasoning: Make sure to thoroughly mix the sauce ingredients so every bite of beef is flavorful.
• Not Thickening the Sauce: Skipping the cornstarch slurry will result in a watery sauce, so don’t forget this step.
