Preparation Phase & Tools to Use (Essential Equipment & Their Importance)

Getting everything prepped before the cooking starts is key to making your Mongolian Beef smooth and stress-free. Stir-fries like this one come together quickly, so having your tools and ingredients ready will ensure you don't miss a beat.

Here’s what you’ll need:

• Sharp Chef’s Knife: Essential for slicing the beef thinly and evenly. Uniform slices mean the meat cooks evenly and stays tender.
• Cutting Board: Preferably a large one to give you space for prepping both meat and aromatics (like garlic and ginger).
• Mixing Bowls: Use one bowl for marinating the beef and another for mixing the sauce. This keeps everything organized and easy to grab.
• Large Skillet or Wok: A wide cooking surface allows for proper searing without crowding the meat, which helps you achieve that nice caramelization.
• Tongs or Wooden Spoon: Ideal for flipping and stirring the beef during cooking without damaging the texture.
• Grater or Microplane: For grating fresh ginger and garlic, which bring a punch of flavor to the sauce.
• Measuring Spoons & Cups: To ensure the perfect balance of sweet and salty in your sauce.
• Paper Towels: To pat dry the beef before searing—this step helps it brown instead of steam.

Preparation Tips

• Slice Against the Grain: When prepping your flank steak or sirloin, always slice against the grain. This shortens the muscle fibers and makes the beef more tender.
• Partially Freeze the Meat: Pop your beef into the freezer for 20–30 minutes before slicing. This firms it up slightly and makes cutting thin slices much easier.
• Use Fresh Aromatics: Fresh garlic and ginger make a huge difference in flavor. Don’t substitute with powders unless absolutely necessary.
• Marinate Briefly: A quick 10-minute marinade in cornstarch and soy sauce helps tenderize the beef and gives it a glossy coating when cooked.
• Don’t Overcrowd the Pan: Sear the beef in batches if needed to avoid steaming. You want those crispy edges!
• Make the Sauce First: Mix all sauce ingredients before you start cooking. Stir-fries move fast, so you won’t have time to measure mid-cook.
• Preheat the Pan Well: A hot pan ensures the beef sears quickly and locks in juices without becoming tough.

Step-by-Step: How to Make Mongolian Beef

Follow these easy steps to create restaurant-style Mongolian Beef right at home. The process is fast and simple, so keep everything prepped and close at hand before you start cooking.

---

Step 1: Prep the Beef

• Slice the flank steak thinly against the grain. For best results, partially freeze the beef for 20–30 minutes first.
• In a bowl, toss the beef with soy sauce and cornstarch until fully coated. Let it sit for 10 minutes while you prep the sauce.

---

Step 2: Mix the Sauce

• In a separate bowl, whisk together soy sauce, brown sugar, water, sesame oil, rice vinegar, garlic, ginger, and red pepper flakes (if using).
• Set aside near the stove — you’ll need it ready once the beef is cooked.

---

Step 3: Sear the Beef

• Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat.
• Sear the beef in batches to avoid overcrowding the pan. Cook each batch for 1–2 minutes per side until browned and slightly crispy. Remove and set aside.

---

Step 4: Cook the Sauce

• In the same pan, add a little more oil if needed and pour in the sauce mixture.
• Let it simmer for 2–3 minutes, stirring occasionally, until it begins to thicken and bubble.

---

Step 5: Combine Beef & Sauce

• Return the cooked beef to the pan and stir well to coat every piece in the thickened sauce.
• Simmer together for another 1–2 minutes until everything is heated through and well-glazed.

---

Step 6: Garnish & Serve

• Remove from heat. Sprinkle with chopped green onions and sesame seeds.
• Serve hot over a bowl of steamed white rice and enjoy every flavorful bite.

---

Notes

• Choose the Right Cut: Flank steak is traditional, but sirloin or skirt steak also work beautifully. Just be sure to slice thinly against the grain for tenderness.
• Control the Sweetness: If you're watching your sugar intake, reduce the brown sugar to ⅓ cup without compromising too much on flavor.
• Double the Sauce: Love saucy stir-fries? Double the sauce ingredients so you can drizzle some extra over your rice or veggies.

Watch Out for These Mistakes While Cooking

• Slicing with the Grain: This results in chewy, tough beef. Always slice against the grain for melt-in-your-mouth texture.
• Skipping the Cornstarch: Cornstarch doesn’t just tenderize—it gives the beef that glossy, lightly crisp exterior. Don’t skip it.
• Overcrowding the Pan: Cooking too much beef at once causes steaming instead of searing. Work in small batches for the best caramelization.
• Burning the Garlic: Garlic burns quickly and can turn bitter. Add it with the sauce, not to an empty hot pan.
• Not Simmering the Sauce Long Enough: The sauce needs a minute or two to bubble and reduce—this is what gives it that rich, sticky finish.
• Using High-Sodium Soy Sauce Without Adjustments: If not using low-sodium soy sauce, cut back on added salt or balance with more water or rice vinegar.
• Not Drying the Beef Before Cooking: Patting the beef dry helps it sear properly instead of steaming in its own moisture.
• Walking Away From the Stove: Stir-fries cook fast. Stay close and keep an eye on heat levels to avoid overcooking.

Storage Instructions

One of the great things about Mongolian Beef is how well it stores and reheats, making it a solid choice for leftovers or meal prep.

• Refrigeration: Store leftovers in an airtight container in the fridge for up to 4 days.
• Reheating: Warm gently on the stovetop over medium heat or in the microwave. Add a splash of water or broth if the sauce thickened too much.

• Make-Ahead Tip: You can slice and marinate the beef a day in advance. The sauce can also be mixed ahead and stored in the fridge separately.
