Ingredients You’ll Need

This Slow Cooker Mongolian Beef Recipe relies on a handful of straightforward, pantry-friendly ingredients, each bringing its own magic to the plate. From the salty depth of soy sauce to the natural sweetness of brown sugar, and the slight crunch and freshness of grated carrots, every component plays a vital role in the final flavor and texture of this dish.

• Flank steak, 1 ½ pounds: This cut is perfect for slow cooking, as it becomes tender without losing its meaty texture.
• Cornstarch, ¼ cup: Used to coat the beef strips, it helps create a slightly thickened, glossy sauce.
• Olive oil, 2 tablespoons: Adds a subtle richness and keeps the garlic from burning when mixed into the sauce.
• Minced garlic, 1 teaspoon: Provides an aromatic punch that enhances the savory elements of the dish.
• Soy sauce, ¾ cup: The salty backbone that gives Mongolian beef its signature umami flavor.
• Water, ¾ cup: Balances the strong flavors and helps create the perfect sauce consistency.
• Brown sugar, ¾ cup: Adds a deep caramel sweetness that contrasts beautifully with the soy sauce.
• Grated carrots, 1 cup: Offer a subtle crunch and fresh pop of color to brighten the dish.
• Green onions and sesame seeds, for garnish: These finishing touches add a burst of freshness and nutty texture.

How to Make Slow Cooker Mongolian Beef Recipe

Step 1: Prepare the Beef

Start by cutting the flank steak into thin, bite-sized strips. Place these strips into a ziplock bag along with the cornstarch. Shake the bag well until every piece is evenly coated. This step helps to lock in juices while cooking and will give your sauce that irresistible silky coating.

Step 2: Make the Sauce

In a medium-sized bowl, whisk together olive oil, minced garlic, soy sauce, water, and brown sugar. This sauce mixture balances salty, sweet, and savory flavors and is essential to turning your beef into a Mongolian masterpiece.

Step 3: Combine Everything in the Slow Cooker

Add the grated carrots and the coated flank steak into the slow cooker. Pour the sauce over the top. Give everything a good stir to make sure the beef strips and carrots are well coated with the sauce. This step ensures the flavors meld beautifully during cooking.

Step 4: Slow Cook to Perfection

Cover the slow cooker and cook on high for 2 to 3 hours or on low for 4 to 5 hours. The long cooking time tenderizes the beef and allows the sauce to thicken and intensify. You’ll know it’s done when the beef is melt-in-your-mouth tender and the sauce has a glossy finish.

How to Serve Slow Cooker Mongolian Beef Recipe

Garnishes

Garnishing with freshly chopped green onions and toasted sesame seeds is a must. The green onions add a fresh, slightly sharp flavor that contrasts the rich sauce, while sesame seeds bring a delightful nutty crunch. These simple touches elevate the presentation and taste effortlessly.

Side Dishes

This dish pairs wonderfully with plain steamed rice which helps soak up the savory sauce. For a more vibrant meal, serve it alongside stir-fried vegetables like broccoli or snap peas, or even a crisp cucumber salad for a cooling contrast.

Creative Ways to Present

For a fun twist, serve your Slow Cooker Mongolian Beef Recipe over cauliflower rice to keep it low carb or wrap the beef in warm lettuce leaves for a handheld delight. You can also drizzle a bit of extra sauce over roasted sweet potatoes for a fusion-inspired treat.

Make Ahead and Storage

Storing Leftovers

Leftovers should be stored in an airtight container in the refrigerator and will stay fresh for up to 3 days. This recipe behaves beautifully the next day as the flavors get even more concentrated.

Freezing

You can freeze the cooked Slow Cooker Mongolian Beef Recipe in freezer-safe containers for up to 2 months. Just be sure to leave some space at the top for expansion, and thaw overnight in the fridge before reheating.

Reheating

Reheat the leftovers gently on the stove over medium heat with a splash of water or broth to loosen the sauce. Alternatively, use the microwave in short bursts, stirring in between, to keep the beef tender and juicy.

FAQs

Can I use a different cut of beef for this recipe?

Yes, while flank steak is ideal because it becomes tender and soaks up the sauce well, you can also use skirt steak or sirloin. Just make sure to slice the meat thinly for the best texture.

Is it possible to make this recipe gluten-free?

Absolutely! Use gluten-free tamari instead of soy sauce to keep all the flavor without the gluten.

Can I prepare this recipe without a slow cooker?

Definitely. You can cook the coated beef in a skillet over medium heat until browned, then simmer with the sauce ingredients until it thickens and the beef is tender. It will just require more active attention.

How do I prevent the sauce from being too watery?

If your sauce is too thin after slow cooking, you can remove the lid and cook on high for an additional 15-20 minutes to reduce it, or mix a little cornstarch slurry and stir it in to thicken quickly.

Can I add other vegetables to this dish?

Yes! Bell peppers, mushrooms, or snap peas make excellent additions. Add more delicate veggies like snap peas in the last hour of cooking to prevent over-softening.
