Ingredients about Slow Cooker Mongolian Beef
To create your Slow Cooker Mongolian Beef, gather the following ingredients:
- 1 1/2 pounds flank steak, thinly sliced against the grain
- 1/4 cup cornstarch
- 1 tablespoon toasted sesame oil
- 1 teaspoon minced garlic

How to Make Slow Cooker Mongolian Beef Directions
Making Slow Cooker Mongolian Beef is an uncomplicated process that delivers impressive results. Begin by slicing the flank steak thinly against the grain. This is crucial as slicing against the grain results in a more tender bite. Coat the sliced beef pieces generously with cornstarch, ensuring they are evenly covered. This coating will help to thicken the sauce and give the beef a delightful texture.
Next, place the coated beef into the slow cooker. Pour in the toasted sesame oil, which not only adds a rich flavor but also enhances the overall aroma of the dish. Add the minced garlic and ginger to the slow cooker for an explosion of flavor. Now, it’s time to bring in the liquid ingredients. Pour in the low-sodium soy sauce, brown sugar, and water, and give everything a gentle stir to combine all the components well.
Set your slow cooker to HIGH and let it cook for 2-3 hours, or select the LOW setting for 4-5 hours. The longer cooking time on low will yield meat that is incredibly tender and infused with flavor. About 15 minutes before serving, stir in the sliced green onions. This not only adds a pop of color but also a refreshing crunch that complements the dish beautifully.
When the cooking time is complete, you’ll be ready to serve this mouthwatering dish over a bed of fluffy rice or noodles. Every bite will offer a tender, savory experience that is sure to impress anyone at your table.
How to Serve Slow Cooker Mongolian Beef
Serving Slow Cooker Mongolian Beef is as simple as it is satisfying. Once your Mongolian beef is ready, you can choose to serve it over rice or noodles. Steamed white rice is a classic option, soaking up the sauce and balancing the dish. Alternatively, you can use egg noodles or rice noodles for a different twist.
To elevate your meal, consider adding a side of stir-fried or steamed vegetables. Broccoli, bell peppers, or snap peas complement the flavors of the Mongolian beef excellently. You may also serve the dish with additional green onions on top for a vibrant garnish. Don’t forget to keep some extra sauce on the side, as many people love to drizzle more over their rice or noodles!
This meal is not only filling but also provides a range of flavors and textures, making it suitable for family dinners or potlucks. It’s a dish that will definitely have your guests raving about your cooking skills!
Expert Tips: Slow Cooker Mongolian Beef
To ensure your Slow Cooker Mongolian Beef comes out perfectly every time, consider these expert tips. Always slice the flank steak against the grain; this technique is essential for achieving tender meat. If slicing it is challenging, freeze the flank steak for about 30 minutes before cutting. This will firm it up and make it easier to slice thinly.
Pay attention to the cooking time; if you’re using a higher quality cut of meat or your slow cooker runs hot, you can opt for a shorter cooking time. It’s better to check the beef for tenderness before the end of the cooking time. If you’re short on time, you can sauté the garlic and ginger before adding it to the slow cooker; this can enhance the flavors even more.
Feel free to tweak the sweetness according to your taste. You can adjust the amount of brown sugar if you prefer a less sweet sauce. And if you love crunch, add vegetables like bell peppers or snap peas to the slow cooker during the last 30 minutes of cooking to keep them vibrant and crisp.
How to Store Slow Cooker Mongolian Beef
Storing your Slow Cooker Mongolian Beef is quite straightforward. Allow the cooked beef to cool down to room temperature before transferring it to an airtight container. Properly stored, you can refrigerate the leftovers for up to 3-4 days.
If you want to store it for a longer duration, consider freezing the Mongolian beef. It can be frozen for up to 2-3 months. When you’re ready to enjoy it again, simply thaw in the refrigerator overnight before reheating. Reheat it on the stove over low heat or in a microwave-safe dish until warmed through. Always ensure it’s heated evenly, especially if it’s been frozen.
Variation of Slow Cooker Mongolian Beef
While the classic recipe for Slow Cooker Mongolian Beef is delightful, you can explore variations to suit your palate. For a spicy kick, add red pepper flakes or sriracha to the sauce before cooking. Alternatively, you can switch up the protein by using chicken or tofu, although you may need to adjust the cooking time accordingly.
To enhance the nutritional profile of your meal, consider adding vegetables right into the slow cooker. Carrots and bell peppers not only add color but also nutrition and flavor. If you prefer a less sweet sauce, you can use less brown sugar or substitute it with a sugar alternative like agave nectar.
For a creative twist, try adding lime or lemon juice at the end of cooking. This bright acidity can bring a fresh dimension to the dish, balancing the richness of the sauce.
