What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Here’s everything you’ll need to whip up this quick savory Mongolian beef:

• Beef: 1 pound (450g) flank steak, thinly sliced against the grain (tender and cooks quickly)
• Cornstarch: ¼ cup (30g) for coating the beef (gives it that crispy edge)
• Vegetable oil: 2 tablespoons for frying (can swap with canola or peanut oil)
• Soy sauce: ½ cup (120ml) low-sodium preferred (adds umami depth)
• Brown sugar: ⅓ cup (67g) packed (balances the savory with sweetness)
• Garlic: 4 cloves, minced (the soul of the sauce)
• Ginger: 1 teaspoon, freshly grated (optional but highly recommended for warmth and zing)
• Green onions: 3, sliced thinly (for freshness and color garnish)
• Red pepper flakes: ¼ teaspoon (optional, adds a subtle kick)
• Water or beef broth: ½ cup (120ml) to balance the sauce

For best results, I prefer using a fresh flank steak from a trusted butcher—thinly slicing it yourself ensures perfect texture. If you want to keep this recipe gluten-free, substitute tamari for soy sauce and double-check your cornstarch brand. Also, in summer, fresh green onions add a lovely pop of color and bite, but scallions will work any time of year.

Equipment Needed

• Large skillet or wok: A heavy-bottomed skillet or wok works best for even cooking and good searing.
• Mixing bowls: For coating the beef and mixing the sauce ingredients.
• Measuring cups and spoons: To get your sauce ratios just right.
• Tongs or a spatula: To flip and toss the beef evenly.
• Sharp knife and cutting board: For slicing the beef thinly and chopping garlic and green onions.

If you don’t have a wok, a large non-stick skillet will do just fine. I’ve tried cast iron too, and it really brings out a nice sear, but be sure to monitor the heat to avoid burning the sugar in the sauce. For those on a budget, a sturdy stainless steel pan is a great option that lasts forever. Just keep your tools sharp—thin beef slices are easier to manage and cook more evenly.

Preparation Method

1. Slice the Beef: Using a sharp knife, thinly slice 1 pound (450g) of flank steak against the grain into strips about ¼ inch (6mm) thick. This helps keep the beef tender. Set aside.
2. Coat the Beef: Place the sliced beef in a medium mixing bowl. Add ¼ cup (30g) cornstarch and toss until each piece is lightly coated. This step is key for that perfect crispy texture.
3. Prep the Sauce: In a small bowl, whisk together ½ cup (120ml) low-sodium soy sauce, ⅓ cup (67g) packed brown sugar, ½ cup (120ml) water or beef broth, minced 4 garlic cloves, 1 teaspoon freshly grated ginger (if using), and ¼ teaspoon red pepper flakes (optional). Set aside.
4. Heat the Oil: In a large skillet or wok, heat 2 tablespoons vegetable oil over medium-high heat until shimmering but not smoking (about 2 minutes). This ensures a quick sear without sticking.
5. Cook the Beef: Add the cornstarch-coated beef in a single layer (you might need to do this in batches). Cook for 2-3 minutes without stirring to get a nice crust, then toss and cook for another 1-2 minutes until browned but not fully cooked through. Remove beef from the pan and set aside.
6. Make the Sauce: Lower heat to medium and pour the sauce mixture into the hot skillet. Stir constantly, scraping up any browned bits from the bottom. Let it simmer for 3-4 minutes until the sauce thickens and becomes glossy.
7. Combine and Finish: Return the beef to the pan, tossing to coat evenly in the sauce. Cook for another 1-2 minutes until beef is cooked through and the sauce clings beautifully.
8. Add Green Onions: Stir in sliced green onions (3 stalks) just before serving for a fresh pop of flavor and color.

Pro tip: Avoid overcrowding the pan when searing the beef, or it will steam instead of crisping up. If your sauce thickens too quickly or starts to burn, add a splash more water or broth to loosen it. You want that sticky, luscious coating without any bitterness.

Cooking Tips & Techniques

Cooking quick savory Mongolian beef is all about timing and technique. Here are some tips I’ve learned through trial and error:

• Thin slices matter: Slicing beef thinly (against the grain) is the secret to tender, quick-cooking meat. If your beef is thick, it’ll take longer and might get tough.
• Don’t skip cornstarch: This coating crisps up the beef in the pan, creating that addictive texture contrast with the sticky sauce.
• High heat is your friend: Searing the beef on medium-high heat locks in juices and creates caramelized edges. But watch carefully—too high and the sauce can burn.
• Batch cooking helps: Overcrowding the pan lowers the temperature and leads to soggy beef. Cook in batches if needed and keep the first batch warm in a low oven.
• Simmer sauce gently: Once you add the sauce, keep it at a gentle simmer to reduce and thicken evenly without burning the sugar.
• Fresh aromatics make a difference: Don’t skimp on garlic and ginger—fresh is best for that punchy, authentic flavor.

I once tried tossing all the beef in cornstarch and sauce at the start and ended up with a clumpy mess—lesson learned! Also, multitasking by prepping ingredients while the beef sears saves precious time.

Variations & Adaptations

This quick savory Mongolian beef recipe is versatile and easy to tweak to your liking:

• Vegetarian version: Swap beef for firm tofu or seitan. Coat and cook the same way for a plant-based take that still offers that crispy, saucy goodness.
• Spicy twist: Add extra red pepper flakes or a splash of sriracha to the sauce for those who like a fiery kick.
• Gluten-free option: Use tamari instead of soy sauce and cornstarch as is. For a low-carb version, try almond flour or coconut flour for coating.
• Seasonal veggies: Toss in sliced bell peppers, snap peas, or broccoli florets during the sauce simmer step for added nutrition and color.
• Sweet swap: Use honey or maple syrup instead of brown sugar for a different kind of sweetness.

Personally, I’ve tried adding thinly sliced shiitake mushrooms and loved the umami boost it gave the dish. Feel free to experiment and make it your own!

Serving & Storage Suggestions

This quick savory Mongolian beef is best served hot and fresh over steamed white rice or fluffy jasmine rice. It also pairs beautifully with simple sides like sautéed bok choy, roasted broccoli, or even crispy egg rolls for a full Chinese-American feast. Garnish with extra sliced green onions or sesame seeds for a little flair.

For leftovers, store the beef and sauce in an airtight container in the refrigerator for up to 3 days. When reheating, warm gently in a skillet over medium heat with a splash of water to loosen the sauce. Avoid microwaving if possible, as it can toughen the beef. Flavors tend to deepen after a day, making leftovers even more flavorful.

If you want to freeze it, portion into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
