What Ingredients You Will Need

This easy one-pot Mongolian beef recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and substitutions are easy if you need them.

• Beef: 1 lb (450g) flank steak or sirloin, thinly sliced against the grain (for tenderness)
• Vegetable oil: 2 tablespoons (for searing the beef; can use canola or avocado oil)
• Garlic: 3 cloves, minced (adds aromatic depth)
• Ginger: 1 tablespoon, freshly grated (brightens the sauce)
• Soy sauce: ½ cup (120ml), low sodium preferred (look for brands like Kikkoman for best consistency)
• Brown sugar: ⅓ cup (70g) packed (balances the saltiness with sweetness)
• Water: ½ cup (120ml) to loosen the sauce
• Green onions: 4 stalks, sliced on the diagonal (for garnish and fresh bite)
• Cornstarch: 2 tablespoons (to thicken the sauce)
• Cold water: 2 tablespoons (to mix with cornstarch)
• Optional: Red pepper flakes for a subtle kick or steamed broccoli for a veggie boost

If you want a gluten-free twist, swap soy sauce with tamari. For a low-sugar version, replace brown sugar with coconut sugar or a sugar substitute like erythritol. The ingredients are straightforward but come together to create a sauce that’s both sticky and silky, making every bite memorable.

Equipment Needed

• Large skillet or wok: A heavy-bottomed skillet works best for even heat distribution; a wok is ideal if you have one.
• Sharp knife: For thinly slicing the beef—honestly, a good knife makes all the difference.
• Cutting board: A sturdy board to prep your ingredients safely.
• Mixing bowls: For marinating and mixing the sauce.
• Measuring cups and spoons: Accuracy helps keep the sauce balanced.
• Spatula or wooden spoon: For stirring without scratching your pan.

If you don’t have a wok, no worries—your trusty skillet does the job just fine. I’ve used both and noticed the wok gives a slightly better sear due to the high sides, but the skillet is more than capable. For budget-friendly options, a non-stick skillet is great and easier to clean, though the caramelization will be better on stainless steel or cast iron.

Preparation Method

1. Slice the beef thinly: Using a sharp knife, cut 1 lb (450g) of flank steak or sirloin against the grain into thin strips, about ¼ inch thick. This helps keep the beef tender. (Tip: Freeze the beef for 15-20 minutes before slicing to make it easier.)
2. Mix the sauce: In a medium bowl, combine ½ cup (120ml) soy sauce, ⅓ cup (70g) brown sugar, ½ cup (120ml) water, minced garlic, and grated ginger. Stir well until the sugar dissolves. Set aside.
3. Prepare the cornstarch slurry: In a small bowl, mix 2 tablespoons cornstarch with 2 tablespoons cold water until smooth. This will thicken the sauce later.
4. Heat the skillet: Over medium-high heat, add 2 tablespoons vegetable oil. Once shimmering, add the sliced beef in a single layer. Avoid overcrowding; cook in batches if needed. Sear for about 2-3 minutes on each side until browned but not fully cooked through. (Tip: Don’t stir too often; this helps get a nice crust.)
5. Remove the beef: Transfer cooked beef to a plate and set aside.
6. Cook the sauce: Lower heat to medium, pour the prepared sauce into the skillet. Bring to a simmer, stirring occasionally. Let it bubble for about 3-4 minutes until it starts to reduce slightly.
7. Thicken the sauce: Give the cornstarch slurry a quick stir and slowly pour it into the simmering sauce while stirring. The sauce will thicken and become glossy within a minute.
8. Return the beef: Add the beef back into the skillet, toss to coat evenly with the sauce. Cook for another 1-2 minutes, allowing the beef to finish cooking and absorb the flavors.
9. Garnish and serve: Sprinkle sliced green onions and optional red pepper flakes over the top. Serve immediately with steamed rice or noodles.

Watch for the sauce consistency—if it gets too thick, add a splash of water. The beef should be tender and coated in a sticky, flavorful sauce. This method keeps everything in one pan, saving time and dishes.

Cooking Tips & Techniques

Getting this easy one-pot Mongolian beef just right is about a few key techniques. First, thinly slicing the beef against the grain is a game-changer for tenderness—you’ll thank me later. Also, don’t rush the searing step; letting the beef form a crisp exterior locks in juices and adds texture.

One common mistake is overcrowding the pan. If you toss too much beef in at once, it steams instead of sears, and you lose that beautiful caramelization. Cook the beef in batches if needed. Another tip: stirring the sauce slowly while adding the cornstarch slurry prevents lumps and gives you that glossy, restaurant-style finish.

Timing is everything here. While the sauce simmers, you can prep your rice or veggies, so everything finishes together. I’ve learned from experience that letting the sauce reduce just enough but not too much keeps it from getting gummy. If that happens, a splash of water fixes it right up.

Lastly, don’t skip the fresh green onions! They add a pop of color and brightness that balances the sweet-savory richness. Trust me, these little details make a big difference.

Variations & Adaptations

This easy one-pot Mongolian beef recipe is versatile and welcoming to tweaks:

• Low-carb option: Serve over cauliflower rice or sautéed zucchini noodles instead of white rice.
• Vegetarian twist: Swap beef with firm tofu or seitan for a plant-based version. Sear tofu until golden for texture.
• Spice it up: Add sliced fresh chili or a teaspoon of chili garlic sauce to the sauce for heat.
• Seasonal veggies: Toss in bell peppers, snap peas, or mushrooms for added crunch and nutrition.
• Gluten-free: Use tamari in place of soy sauce and cornstarch (ensure gluten-free brand) for thickening.

Personally, I once tried adding thinly sliced carrots and broccoli florets halfway through cooking for a colorful, nutrient boost. It was a hit! Feel free to customize based on what’s in your fridge or your mood.

Serving & Storage Suggestions

Serve this easy one-pot Mongolian beef hot over steamed jasmine rice or your favorite noodles. The glossy sauce clings beautifully, making every bite satisfying. For a fresh touch, sprinkle extra green onions or sesame seeds on top. If you want to turn it into a full meal, steamed or stir-fried veggies pair wonderfully.

Store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of water or broth to loosen the sauce and warm gently on the stovetop or microwave. The flavors actually deepen after a day, so leftovers can be even better.

If you want to freeze, portion into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating. Just keep in mind that the texture of the beef can soften slightly after freezing, but the sauce remains delicious.
