The great thing about this Mongolian Beef Recipe is that it uses simple, easy-to-find ingredients that each play an important role in building flavor and texture. From tender flank steak to fresh carrots and red bell peppers, every element contributes to an incredibly satisfying dish.

Flank steak: Thinly sliced against the grain for tender, juicy beef with a great bite.
Cornstarch: Provides a crispy coating on the beef when pan-fried.
Carrot and red bell pepper: Add natural sweetness, vibrant color, and crisp texture.
Green onions: Bring fresh oniony brightness that lifts the dish.
Garlic and fresh ginger: Infuse the sauce with deep, aromatic flavors.
Brown sugar: Creates the signature sweet undertone that balances the soy sauce.
Low-sodium soy sauce: Adds saltiness and umami without overpowering.
Sriracha: Brings a subtle heat that you can adjust to your liking.
Butter and neutral oil: Give you that tasty sear and richness.
Sesame seeds (optional): For a nutty garnish that adds a nice finishing touch.

Directions

Step 1: Start by placing your thinly sliced beef in a bowl and tossing it with the cornstarch until every piece is evenly coated. This step is crucial for getting that crispy texture on the outside once you start cooking.

Step 2: In a separate bowl, whisk together the brown sugar, water, low-sodium soy sauce, grated garlic, grated ginger, and Sriracha until the brown sugar dissolves completely. Set this sauce mixture aside while you cook the beef and veggies.

Step 3: Heat 1 tablespoon of oil with 1 tablespoon of butter in a large skillet or wok over medium-high heat. Once it’s hot, add the julienned carrots and sliced red bell peppers. Stir-fry them until they’re crisp-tender, which usually takes about 3-4 minutes, stirring frequently to prevent burning. Then, scoop them out onto a separate plate.

Step 4: Increase the heat to high and add the remaining 1 tablespoon of oil to the skillet. When the oil is shimmering, add the coated beef slices in a single layer without overcrowding the pan—you may need to do this in batches. Sear the beef for about 2 minutes on each side so it gets that beautiful golden-brown crust. Add a bit more oil if your pan gets too dry.

Step 5: Return the cooked vegetables and the thickly sliced green onions to the skillet. Pour in the sauce you prepared earlier and stir everything together. Reduce the heat to medium-low and let it simmer for around 3 minutes, or until the sauce thickens and beautifully coats the beef and vegetables. Garnish with sesame seeds if you like, then serve immediately.

Servings and Timing

This recipe serves 4 hungry people and is ideal for a family dinner or small gathering. You’ll spend about 10 minutes prepping the ingredients, especially if you have your veggies julienned and beef sliced ahead of time. Cooking itself takes roughly 20 minutes, including stir-frying the veggies, searing the beef, and simmering the sauce. Altogether, you’re looking at around 30 minutes from start to finish, with no resting or cooling time required.

How to Serve This Mongolian Beef Recipe

The dish shows a white plate with a base layer of fluffy white rice. On top of the rice is a thick layer of dark brown cooked beef strips mixed with thin orange carrot strips, bright green chopped scallions, and small red chili slices. The beef and vegetables are covered with a shiny dark sauce and sprinkled with small white sesame seeds. A silver spoon rests inside the plate on the right side. The whole plate is placed on a white marbled surface with a green and white cloth nearby. Photo taken with an iphone --ar 4:5 --v 7

When serving this Mongolian Beef Recipe, I love pairing it with steamed jasmine rice or fluffy white rice to soak up all that delicious sauce. For a lighter option, cauliflower rice works beautifully and helps keep things fresh. If you’re in the mood to add some greens, steamed broccoli or sautéed snap peas are great companions that complement the savory-sweet flavors without overpowering them.

Presentation-wise, I like to mound the beef and vegetables over a bed of rice and sprinkle a few extra green onions and sesame seeds on top for color and texture. Using a wide, shallow bowl or plate helps showcase the vibrant vegetables and glossy sauce. For beverages, a slightly chilled glass of Riesling or a crisp beer pairs nicely, but I also adore serving it with a cold ginger ale or iced green tea for a non-alcoholic option.

This dish is perfect for warming up chilly weeknights or impressing guests at casual gatherings. I recommend serving it hot or warm to really appreciate the texture of the crispy beef and the freshly cooked vegetables. Leftovers can be gently reheated, though freshly made is always best to enjoy that perfect saucy crunch.

Variations

Over time, I’ve experimented with different twists on this Mongolian Beef Recipe to suit various tastes and dietary needs. One simple variation is swapping flank steak for sirloin or skirt steak if you prefer a slightly fattier cut that still cooks quickly. For a leaner option, you can use thinly sliced chicken breast or even firm tofu for a vegetarian twist—the sauce adapts beautifully to these changes.

If you need a gluten-free version, just make sure to use tamari or a gluten-free soy sauce instead of regular soy sauce. You can also swap out the cornstarch for arrowroot powder to keep the crispy coating intact. For those who like their meals with a little more heat or complexity, adding finely chopped fresh chili or a touch more Sriracha can take the spice level up several notches.

Different cooking methods can also be fun to try. While I usually stir-fry in a skillet or wok for that perfect sear, this recipe works well under a broiler too. Lay the coated beef slices on a baking sheet and broil them briefly to get a similar crispy texture before tossing with the sauce and veggies.

Storage and Reheating

Storing Leftovers

If you have any leftovers from this Mongolian Beef Recipe, store them in an airtight container once the dish has cooled to room temperature. Glass or BPA-free plastic containers work best to keep flavors fresh. You can safely refrigerate your leftovers for up to 3 days, making it an excellent option for quick lunches or second dinners.

Freezing

Although I love enjoying this Mongolian Beef fresh, you can freeze leftovers if needed. Place the cooled beef and vegetables with sauce into freezer-safe containers or heavy-duty freezer bags, removing as much air as possible to prevent freezer burn. It’s best to freeze in portion sizes so you only thaw what you’ll eat. These will keep well for up to 2 months. When you’re ready, thaw overnight in the refrigerator before reheating.

Reheating

The best way to reheat Mongolian Beef is gently in a skillet over medium heat with a splash of water or broth to loosen the sauce and prevent drying out. Avoid microwaving if possible, as it can make the crispy beef lose its texture and become chewy. Stir frequently until heated through and the sauce is glossy again. If the sauce thickens too much, just add a little extra liquid and stir to bring it back to life.

FAQs

Can I use other cuts of beef for this Mongolian Beef Recipe?

Absolutely! While flank steak is ideal for its tenderness and quick cooking time, you can use sirloin, skirt steak, or even ribeye if you want a bit more marbling. Just remember to slice thinly against the grain for the best texture.

Is this recipe spicy? Can I adjust the heat?

The recipe includes Sriracha to add a mild kick, but you can easily adjust the spiciness. If you prefer no heat, simply leave it out or add less. For more spice, increase the Sriracha or add fresh chilies or chili flakes to your taste.

Can I make this dish vegan or vegetarian?

Yes! Replace the beef with firm tofu, tempeh, or even seitan for a plant-based version. Use a vegan soy sauce and adjust cooking times accordingly. The sauce is naturally vegan-friendly aside from the butter, which you can substitute with oil or vegan butter.

Do I need to marinate the beef before cooking?

No marinating is necessary since the cornstarch coating ensures a crispy texture and the sauce adds plenty of flavor during cooking. This keeps the process quick and simple without sacrificing taste.

Can I prepare parts of this recipe ahead of time?

Definitely! You can slice the beef and vegetables a few hours or even a day ahead to save time. The sauce mix can also be made in advance and refrigerated until ready to use. Just wait to cook everything fresh for the best texture.

Conclusion

I’m so excited for you to try this Mongolian Beef Recipe! It’s one of those dishes that feels both special and approachable at the same time—a perfect weeknight meal or a dish to impress your guests.
