One of the great things about this Slow Cooker Mongolian Beef recipe is its versatility. You can easily customize the dish to suit your preferences or dietary needs. For a healthier option, consider using leaner cuts of beef or adding more vegetables. Bell peppers, broccoli, or snap peas can be tossed in during the last hour of cooking for added nutrition and color.

If you prefer a spicier kick, simply increase the amount of red pepper flakes or add a splash of sriracha to the sauce. Additionally, this recipe serves as a fantastic base for meal prep.

Perfect Pairings

When it comes to serving Slow Cooker Mongolian Beef, the options are endless. While it's traditionally enjoyed over rice or noodles, feel free to experiment with different sides. Steamed jasmine rice or brown rice are excellent choices, but you can also serve it with cauliflower rice for a lower-carb option. If you're looking to add more texture, crispy egg noodles or even a fresh salad can complement the dish beautifully.

To round out your meal, consider pairing it with a light appetizer or dessert. Spring rolls or dumplings make great starters, while a refreshing fruit salad can be a perfect ending to your meal. With so many pairing possibilities, you can create a restaurant-quality dining experience right at home.

Ingredients

Gather the following ingredients to make this delicious Mongolian Beef:

Ingredients

  • 2 lbs flank steak, sliced against the grain
  • 1/2 cup soy sauce
  • 1/2 cup brown sugar
  • 1/4 cup water
  • 1 tablespoon minced garlic
  • 1 tablespoon minced ginger
  • 1/4 teaspoon red pepper flakes
  • 1/4 cup cornstarch
  • 2 tablespoons vegetable oil
  • 1 bunch green onions, chopped

Make sure to have all ingredients prepped before starting your slow cooker.

Instructions

Follow these steps to create your Slow Cooker Mongolian Beef:

Prepare the Beef

In a bowl, combine the sliced flank steak with cornstarch until well-coated. This will help in thickening the sauce later.

Make the Sauce

In a separate bowl, whisk together soy sauce, brown sugar, water, minced garlic, minced ginger, and red pepper flakes.

Combine in Slow Cooker

Add the coated beef to the slow cooker, then pour the sauce over it. Stir to combine.

Cook

Cover and cook on low for 8 hours or on high for 4 hours until the beef is tender.

Finish and Serve

Once cooked, stir in chopped green onions and serve over rice or noodles. Enjoy your meal!

Let your Slow Cooker Mongolian Beef sit for a few minutes before serving to allow the flavors to meld.

Storing Leftovers

If you happen to have leftovers, you're in luck! Slow Cooker Mongolian Beef stores well in the refrigerator for up to three days. Simply transfer the cooled beef and sauce into an airtight container to keep it fresh. For longer storage, consider freezing the dish. It can be frozen for up to three months. Just make sure to label your containers with the date so you can keep track of freshness.

When you're ready to enjoy your leftovers, reheat them in the microwave or on the stovetop. If the sauce has thickened too much in the fridge, you can add a splash of water or broth while reheating to reach your desired consistency.

Tips for Success

To achieve the best results with this recipe, it's essential to slice the flank steak against the grain. This ensures that the meat remains tender and easy to chew. Additionally, don't skip the cornstarch coating; it plays a vital role in thickening the sauce and giving it a luscious texture.

For optimal flavor, consider marinating the beef in the sauce for a few hours before adding it to the slow cooker. This step is especially helpful if you have time the night before. Just mix the sauce ingredients and let the beef soak overnight for a deeper flavor.
