Ingredients

If you have any ingredients leftover from this small batch Mongolian Beef recipe, check out our Leftover Ingredients Recipe Finder.
- Flank Steak: The best cut for Mongolian beef. It’s lean, flavorful, and budget-friendly. If flank steak isn’t available, skirt steak or hanger steak work well. Flat iron or sirloin steak are also good options. Leftover flank steak? Use it in Carne Asada and Steak Fajitas.
- Pro Tip: For tender beef, slice against the grain into 1/4-inch thick strips. A sharp knife helps with precision. Freezing the steak for 20 minutes before slicing makes it easier to cut thinly without tearing.
- Cornstarch: Thickens the sauce and gives it a glossy finish. If unavailable, flour can be used, but the sauce won’t have the same clear sheen.
- Soy Sauce: Provides a rich umami flavor. I use low sodium soy sauce to better control the salt level. Regular soy sauce works but will make the dish saltier. For a gluten-free option, use tamari.
- Brown Sugar: Adds sweetness and balances the salty soy sauce. White sugar can be used but lacks the depth of flavor from molasses. You can also try homemade brown sugar, honey, or maple syrup.
- Vegetable or Avocado Oil: Ideal for stir-frying due to their high smoke points. Canola, sunflower, or grapeseed oil are good alternatives.
- Fresh Ginger: Adds warmth and depth. Leftover ginger? Use it in Chicken Tikka Masala, Saag Paneer, or a Green Smoothie. If fresh ginger isn’t available, use 1/8 teaspoon of ground ginger per teaspoon of fresh.
- Garlic: Essential for building flavor. If fresh garlic isn’t available, substitute with jarred minced garlic or 1/8 teaspoon of garlic powder.
- Green Onions: Add color and mild onion flavor. If unavailable, chives, leeks, or shallots can work, though leeks and shallots have a stronger taste.
Recipe Variations
Mongolian Beef is easy to customize! Here are a few ways to change up the dish:
- Spicy Mongolian Beef: Add red pepper flakes, sliced jalapeños, or a dash of sriracha for extra heat.
- Vegetable-Packed: Stir in bell peppers, broccoli, snap peas, or carrots for added color and nutrition.
- Extra Crunch: Top with toasted sesame seeds or crushed peanuts for a bit of texture.

Delicious! Made this tonight, doubled the recipe, and hubby loved it. Added 1/4 tsp chili flakes
Another delicious, easy recipe! Thank you!
Joanne, once again, another delicious recipe will be making this again!
So satisfying! I made as directed and was so yummy. Next time I’ll try adding asparagus, or green pepper, or broccoli or….
Made this for my dinner this evening. It was very tasty.
Thank you. I’m so happy you enjoyed it.
Hi Joanie! First off, thank you for all you do to support us one-two person households who were used to cooking larger meals for more. It’s difficult to adjust to making smaller meals, so I’m appreciative of all you do. I’m positive others’ will agree.
I have a bottle of hoisin sauce in the fridge. Do you think I could sub maybe 1/2 cup in place of the soy sauce/water? I love hoisin sauce and use it in place of catsup and bbq sauce depending on the recipe. Thank you once again.
Thank you, Kaitlyn. I think hoisin sauce should work just fine.
Made it tonight for dinner. Delicious! Added 2 very thinly sliced zucchini. Will definitely make again.
I’m so happy you enjoyed it!
Good recipe.
Thank you!
Is step 6 supposed to be : add the steak back to the pan and mix with the sauce?
Yes, add the steak back to the pan and stir frequently for 2-3 minutes, or until the sauce has thickened.
Good recipe. Didn’t have low sodium soy sauce so used regular. Might try again with low sodium sauce to compare. Definitely worth making again.
