- 1 1/2 pounds flank steak: Thinly sliced against the grain for the most tender and juicy results.

- 1 teaspoon minced garlic: Provides an essential punch of fragrant flavor that wakes up the taste buds.
- 1 teaspoon minced ginger: Brings a zesty warmth that rounds out the sauce beautifully.
- 1/2 cup low sodium soy sauce: A key umami ingredient that balances sweetness and saltiness effortlessly.
- 1/3 cup brown sugar: Sweetens the sauce while creating that glorious caramelized finish.

How to Make Slow Cooker Mongolian Beef Recipe
Step 1: Coat the Beef
Start by tossing the thinly sliced flank steak with cornstarch in a mixing bowl. This coating is essential because it thickens the sauce as the beef cooks and helps seal in juices, giving you tender yet flavorful pieces every time.
Step 2: Combine Ingredients in the Slow Cooker
Place the coated steak directly into your slow cooker. Add toasted sesame oil, minced garlic and ginger, soy sauce, brown sugar, and water on top. Give everything a gentle stir to blend the flavors without disturbing the cornstarch coating on the beef. This careful step ensures the sauce stays luscious and the meat doesn’t lose its tender bite.
Step 3: Let It Slow Cook
Cover your slow cooker and set it to HIGH for 2 to 3 hours or LOW for 4 to 5 hours. This slow and gentle cooking time is where magic happens—the beef softens beautifully and soaks up all those rich, sweet, and savory notes, resulting in a melt-in-your-mouth texture that’s totally crave-worthy.
Step 4: Add Fresh Green Onions
To finish, stir in the fresh green onions just before serving. Their crispness and bright flavor create a perfect contrast to the rich sauce, giving the dish a lift both in taste and presentation.
How to Serve Slow Cooker Mongolian Beef Recipe
Garnishes
While green onions are the classic garnish, feel free to jazz it up with a sprinkle of toasted sesame seeds or a few thin slices of fresh red chili if you like a touch of heat. These simple additions add an extra layer of texture and visual appeal that makes the dish feel extra special.
Side Dishes
This Slow Cooker Mongolian Beef Recipe pairs beautifully with steamed jasmine rice or fluffy white rice to soak up every drop of that luscious sauce. For a low-carb option, serve it atop cauliflower rice or alongside stir-fried vegetables like broccoli and snap peas to keep things bright and balanced.
Creative Ways to Present
If you’re aiming to impress, try serving the Mongolian beef over crispy fried noodles or in lettuce wraps for a fun, interactive meal that’s perfect for sharing. You can also turn leftovers into a delicious noodle bowl topped with fresh herbs and a squeeze of lime for a quick lunch that feels anything but boring.
Make Ahead and Storage
Storing Leftovers
When you have leftover Slow Cooker Mongolian Beef, simply transfer it to an airtight container and store it in the refrigerator. It will stay fresh for up to 3 days, making it a convenient option for easy meals throughout the week.
Freezing
If you want to meal prep or save some for later, this recipe freezes beautifully. Place cooled leftovers in a freezer-safe container or bag and freeze for up to 3 months. Just remember to leave some room for expansion!
Reheating
Reheat your Mongolian beef gently on the stove over low heat or in the microwave. Add a splash of water if the sauce has thickened too much to bring back that luscious consistency. Either way, the flavors will be just as vibrant as when freshly made.
FAQs
Can I use a different cut of beef?
Absolutely! While flank steak is ideal because of its texture and flavor, you can substitute with skirt steak or sirloin thinly sliced. Just be mindful that cooking times might vary slightly depending on the thickness and cut.
Do I need to marinate the beef before slow cooking?
No marinating is required for this Slow Cooker Mongolian Beef Recipe. The cornstarch coating and slow cooking process allow the beef to absorb all the flavors perfectly without extra prep time.
Is this recipe spicy?
The original recipe is mild but full of sweet and savory depth. If you love spice, feel free to add red pepper flakes or fresh chili peppers to the slow cooker for an extra kick.
Can I make this recipe in an Instant Pot?
You can! Use the sauté function for the initial step, then pressure cook on high for about 15 minutes. Just make sure to adjust the liquid as needed to prevent burning.
What can I substitute for brown sugar?
If you don’t have brown sugar on hand, coconut sugar or even honey can work as alternatives, but the flavor and texture of the sauce might shift slightly. Brown sugar adds that signature caramel note that’s hard to beat.
