What is Mongolian Beef in a Slow Cooker?

Mongolian Beef is a savory dish that features thinly sliced beef cooked with ingredients like soy sauce, brown sugar, and green onions. Utilizing a slow cooker amps up the flavor and tenderness, making the process virtually hassle-free. 

The heat and moisture allow the beef to absorb the sauce completely, resulting in meat that is melt-in-your-mouth tender. The original dish is often associated with American-Chinese cuisine rather than traditional Mongolian food, but that should not dim its appeal.

Why This Recipe Works

Convenience: Slow cookers are fantastic for busy folks. With minimal effort, you can toss in your ingredients and let the cooker work its magic. After a long day, coming home to a prepared meal is truly a blessing.

Deep Flavors: The slow cooking process allows the soy sauce, ginger, and garlic to deeply infuse the beef, resulting in complex flavors that standard cooking methods just can’t achieve.

Tender Texture: Slicing the flank steak thinly and cooking it slowly ensures tenderness. The low and slow method breaks down fibers in the meat, making it easier to chew and enjoy.

Flexibility: This recipe is adaptable. Don’t have flank steak? You can use various cuts of beef. Prefer spice? Just bump up the red pepper flakes; this dish plays well with your tastes.

Ingredients You’ll Need To Make This Mongolian Beef Slow Cooker

To whip up this savory delight, gather the following ingredients:

1/4 cup cornstarch: To coat the beef for added texture.
1 1/2 pounds flank steak, thinly sliced across the grain: The star of your dish.
1 tablespoon toasted sesame oil: Adds a rich, nutty flavor.
1/2 cup low-sodium soy sauce: The foundation for your sauce.
1/3 cup packed brown sugar: Offers sweetness and balances the saltiness.
1 teaspoon fresh garlic, minced: For that classic aromatic punch.
1 teaspoon fresh ginger, minced: Gives it that zesty kick.
1/2 cup water: To assist with the cooking process.
1/2 cup green onions, chopped into 1/2-inch pieces: For garnish and crunch.
1 teaspoon rice vinegar: Adds a tangy contrast.
1/2 teaspoon crushed red pepper flakes: For a hint of heat.

How To Make This?

Let’s dive into the steps that will bring this delicious dish to your table.

Step 1: Prepare the Beef

Start by slicing the flank steak thinly against the grain. This is essential, as slicing against the grain makes the beef more tender. Once sliced, toss it with cornstarch in a bowl. This step helps to create a slight crust when cooked, enhancing the texture.

Step 2: Sauté the Aromatics

In a skillet, heat the toasted sesame oil over medium heat. Add the minced garlic and ginger, sautéing for about a minute until fragrant. Don’t walk away—the aromas are intoxicating, and you don’t want to burn them.

Step 3: Combine the Sauce

In a mixing bowl, whisk together the soy sauce, brown sugar, water, and rice vinegar. You want to dissolve the sugar completely. This sweet, tangy mixture is key to the dish’s flavor profile.

Step 4: Assemble in the Slow Cooker

In the slow cooker, combine the beef with the sautéed garlic and ginger. Pour the sauce over the beef, ensuring everything is well-coated. Throw in the chopped green onions, stirring lightly.

Step 5: Slow Cook

Set your slow cooker to low heat and cook for 4-6 hours. If your day is busier, set it up for high heat for 2-3 hours. Stir occasionally if you can; it helps mix the flavors.

Step 6: Serve!

After cooking, check for tenderness. The beef should flake easily with a fork. Serve it hot, garnished with extra green onions.
