Ingredients You’ll Need
The magic of this Slow Cooker Mongolian Beef Recipe lies in its straightforward, simple ingredients that work beautifully together. Each element contributes a vital note— from tenderizing the beef to building that signature rich, glossy sauce that Mongolian beef is famous for.
- 2 pounds of flank steak or beef chuck roast (thinly sliced against the grain): Choosing the right cut and slicing against the grain guarantees tender, easy-to-chew beef.
- 1/4 cup cornstarch: This not only helps coat the beef for a silky texture but also thickens the sauce perfectly later on.
- 1/2 cup low-sodium soy sauce: The savory backbone of the sauce, low-sodium ensures it’s flavorful without being overpowering.
- 1/2 cup brown sugar: Adds the essential sweetness and caramel notes that balance soy’s saltiness beautifully.
- 1/4 cup water: Helps to blend the sauce ingredients and create the ideal saucy consistency.
- 2 cloves garlic (minced): Fresh garlic brings that aromatic kick that makes every bite irresistible.
- 1 tablespoon fresh ginger (grated): Adds warmth and a subtle spice, enhancing the dish’s depth.
- 1/4 teaspoon red pepper flakes (optional): For those who love a hint of heat, these add just the right touch of fiery excitement.
- 2 green onions (sliced for garnish): Fresh, vibrant, and crunchy, they add a lovely pop of color and mild onion flavor at the end.
How to Make Slow Cooker Mongolian Beef Recipe
Step 1: Prepare the Beef
Start by thinly slicing your flank steak or chuck roast against the grain—this step is crucial for tender results. Toss the beef slices with cornstarch in a large bowl until every piece is evenly coated. The cornstarch ensures a silky texture on the beef and helps thicken the sauce later, so don’t skip this step!
Step 2: Mix the Sauce
In a separate bowl, whisk together the low-sodium soy sauce, brown sugar, water, minced garlic, grated ginger, and optional red pepper flakes. This perfectly balanced sauce combines sweet, savory, and slightly spicy notes that make Mongolian beef so addictive. Taking a moment here to mix these thoroughly ensures each bite is packed with flavor.
Step 3: Layer in the Slow Cooker
Place your coated beef at the bottom of your slow cooker, layering the slices gently to avoid clumping. Pour the sauce evenly over the beef, making certain that every piece is coated in that rich, fragrant mixture. This layering ensures that the flavors infuse beautifully as it cooks low and slow.
Step 4: Cook
Cover your slow cooker and cook on low for 6 to 8 hours, or if you need it sooner, set it on high for 3 to 4 hours. Keep in mind that slow cooker models vary, so it’s a great idea to check the beef around the earlier time mark for tenderness. When the beef is fork-tender and the sauce has melded into a glossy, flavorful glaze, you’re ready for the final touch.
Step 5: Finish and Serve
If you find the sauce a little too thin for your liking, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water and stir it into the slow cooker. Cook on high for an additional 15 minutes until the sauce thickens up beautifully. Give it a good stir, and your Slow Cooker Mongolian Beef Recipe is ready to be devoured!

Make Ahead and Storage
Storing Leftovers
Any leftover Slow Cooker Mongolian Beef Recipe can be stored in an airtight container in the refrigerator for 3 to 4 days. This makes for an easy, delicious lunch or dinner that reheats wonderfully without losing any of its flavor or tenderness.
Freezing
If you want to keep this dish longer, freezing is a great option. Place cooled Mongolian beef in freezer-safe containers or bags, and it will stay fresh for up to 3 months. When ready to enjoy, thaw overnight in the fridge for best results.
Reheating
To reheat, gently warm the beef in a skillet over medium heat or in the microwave. If the sauce has thickened too much, add a splash of water to loosen it so it coats the beef nicely again. Reheated Mongolian beef tastes just as amazing as fresh!
FAQs
Can I use other cuts of beef for this recipe?
Absolutely! While flank steak or chuck roast are ideal for tenderness, you can experiment with sirloin or skirt steak as long as you slice it thinly against the grain to keep it tender.
Is it important to slice the beef against the grain?
Yes, slicing against the grain breaks up the muscle fibers, making the beef much easier to chew and overall more tender—this is key for that melt-in-your-mouth experience.
Can I make this recipe Spicy?
Definitely! The red pepper flakes add a gentle heat, but you can increase the amount or add chili oil or fresh chopped chilies for a spicier kick.
How do I thicken the sauce if it’s too thin?
Mix 1 tablespoon of cornstarch with 2 tablespoons of cold water to create a slurry, then stir it into the slow cooker and cook on high for 15 minutes until thickened to your liking.
Is this dish gluten-free?
To make it gluten-free, simply use a gluten-free soy sauce or tamari. All other ingredients are naturally gluten-free.

Description
Slow Cooker Mongolian Beef is a tender and flavorful dish where thinly sliced beef is slow-cooked in a rich, sweet, and savory sauce made with soy sauce, brown sugar, garlic, and ginger. Perfect for an easy, hands-off meal that delivers deep flavors with minimal effort.
Ingredients
Beef
- 2 pounds flank steak or beef chuck roast, thinly sliced against the grain
- 1/4 cup cornstarch
Sauce
- 1/2 cup low-sodium soy sauce
- 1/2 cup brown sugar
- 1/4 cup water
- 2 cloves garlic, minced
- 1 tablespoon fresh ginger, grated
- 1/4 teaspoon red pepper flakes (optional)
Garnish
- 2 green onions, sliced
Instructions
- Prepare the beef: Slice your beef thinly against the grain to ensure tender and easy-to-eat pieces. Toss the sliced beef with cornstarch in a large bowl until all pieces are evenly coated. This helps thicken the sauce and gives the beef a nice texture.
- Mix the sauce: In a separate bowl, whisk together soy sauce, brown sugar, water, minced garlic, grated ginger, and red pepper flakes if using. This mixture will create the signature sweet and savory flavor of the dish.
- Layer in the slow cooker: Place the cornstarch-coated beef in the bottom of your slow cooker. Pour the prepared sauce evenly over the beef, making sure all slices are covered to infuse maximum flavor during cooking.
- Cook: Cover the slow cooker and cook on low for 6 to 8 hours, or on high for 3 to 4 hours. Cooking times may vary depending on your model, so check for tenderness towards the shorter end of the timing. The beef will become tender and the sauce will meld beautifully.
- Finish and serve: Once the beef is tender, stir the contents well. If the sauce appears too thin, combine 1 tablespoon cornstarch with 2 tablespoons cold water to make a slurry, then stir it into the slow cooker. Cook on high for an additional 15 minutes or until the sauce thickens to your desired consistency. Garnish with sliced green onions before serving.
Notes
- For best results, slice the beef while it is partially frozen to get thinner slices.
- You can adjust the sweetness of the sauce by adding more or less brown sugar to taste.
- Use low-sodium soy sauce to control the saltiness of the dish.
- If you prefer a spicier version, increase the amount of red pepper flakes or add a dash of sriracha.
- This dish pairs wonderfully with steamed rice or sautéed vegetables.
- Leftovers store well in the refrigerator for up to 3 days and freeze up to 2 months.
