How to Make Slow Cooker Mongolian Beef
Step 1: Prepare the Beef
Slice your beef thinly against the grain to ensure maximum tenderness. Toss it with a little vegetable oil and cornstarch to help create a crispy coating once slow cooked.
Step 2: Mix the Sauce
In a separate bowl, combine soy sauce, brown sugar, minced garlic, and fresh grated ginger. Stir until the sugar dissolves and the mixture smells fragrant.
Step 3: Combine in the Slow Cooker
Place the beef in the slow cooker first, then pour the sauce evenly over the meat. Toss gently to coat all the pieces thoroughly.
Step 4: Cook Low and Slow
Set your slow cooker to low heat and cook for 4 to 6 hours. The low and slow method tenderizes the beef and allows the flavors to meld beautifully.
Step 5: Thicken the Sauce
About 30 minutes before serving, stir in a cornstarch slurry (cornstarch mixed with a little water) to thicken the sauce to a luscious consistency.
Pro Tips for Making Slow Cooker Mongolian Beef
- Use Thinly Sliced Beef: Slicing against the grain ensures every bite is tender and easy to chew.
- Don’t Skip the Sauce Stirring: Mix the brown sugar well into the soy sauce to avoid grainy texture.
- Layer Flavor: Adding fresh garlic and ginger makes a huge difference in complexity.
- Use the Thickening Step: Adding cornstarch slurry towards the end guarantees a restaurant-quality glossy finish.
- Serve Immediately After Thickening: The sauce thickens as it cools, so enjoy your Mongolian beef when it’s fresh and warm.

FAQs
Can I use other types of beef for this recipe?
Absolutely! While flank steak or sirloin works best for tenderness, you can substitute with skirt steak or even chuck roast, though cooking times may vary.
Is it possible to make this recipe without a slow cooker?
Yes, you can make a quicker version on the stovetop by simmering the beef and sauce gently for 30 to 40 minutes, but slow cooking yields the best tender results.
How do I prevent the beef from becoming tough?
Be sure to slice beef thinly against the grain and cook it low and slow; overcooking or slicing with the grain can make it chewy.

Definitely! Use gluten-free tamari instead of soy sauce and double-check your other ingredients to ensure they contain no gluten.

Feel free to try cauliflower rice, quinoa, or even noodles, depending on your dietary preferences and what you have on hand.
