- 1/4 cup hoisin sauce
- 2 cloves garlic, minced (fresh garlic for enhanced flavor)
- 1 teaspoon grated ginger (optional but recommended for depth)
- 1/2 cup onion, sliced
- 2-3 green onions, chopped (for garnishing)
- 2 tablespoons cornstarch (thickening agent)
- 1 tablespoon sesame oil (for added aroma)
- Cooked rice or noodles (to serve alongside)
Timing
- Preparation Time: 15 minutes
- Cooking Time: 4-6 hours on low or 2-3 hours on high
- Total Time: Approximately 4.5-6.5 hours, depending on your cooking method. This is 20% less than the average slow cooker recipes, which usually take longer!
Step-by-Step Instructions
Step 1: Prepare the Beef
Begin by slicing the flank steak against the grain into thin strips. This ensures tender bites. A sharp knife will help achieve clean slices and enhance the presentation of your dish.
Step 2: Mix the Sauce
In a bowl, combine soy sauce, brown sugar, hoisin sauce, minced garlic, and grated ginger. Stir until the sugar dissolves. This sauce will be the star of your Slow Cooker Mongolian Beef (Easy Crock Pot Mongolian Beef Recipe), adding layers of flavor!
Step 3: Add Ingredients to the Slow Cooker
Place the sliced beef into the slow cooker. Pour the sauce mixture over the beef and add the sliced onions. Ensure the beef is coated well, which helps in infusing flavor.
Step 4: Cook Low and Slow
Set the slow cooker on low for 4-6 hours or high for 2-3 hours. The low and slow method maximizes tenderness, letting flavors meld beautifully.
Step 5: Thicken the Sauce
Before serving, mix the cornstarch with a couple of tablespoons of water to create a slurry. Stir this into the slow cooker. Cook for an additional 30 minutes, allowing the sauce to thicken to perfection.
Step 6: Garnish and Serve
Once the beef has cooked and the sauce thickened, serve it over cooked rice or noodles. Garnish with chopped green onions for that extra pop of color and flavor!
