It coats every tender piece of beef, creating a deeply satisfying experience that will leave you wanting more.

It’s a delicious and often healthier alternative to restaurant versions.
  • Highly Customizable: This recipe serves as a fantastic foundation for your culinary creativity. Want to add more vegetables? Bell peppers, carrots, or snap peas would be excellent additions. Prefer a bit of heat? A dash of chili flakes or sriracha can easily elevate the spice level. You can even experiment with other proteins like chicken or pork for variation.

Essential Ingredients for the Perfect Mongolian Beef and Broccoli

Crafting exceptional Mongolian Beef and Broccoli starts with selecting the right ingredients. Each component plays a vital role in building the dish’s signature flavor and texture.

Choosing Your Beef

For convenience, pre-cut beef “stir fry strips” available at most grocery stores are an excellent choice. They save time and are typically cut to an ideal thickness. However, if these aren’t available, or you prefer to cut your own, select a lean and tender cut like flank steak, sirloin steak, or skirt steak. These cuts are perfect for stir-frying as they cook quickly and absorb flavors beautifully. You don’t need an expensive cut for this recipe; the marinade and quick cooking process ensure the beef remains moist and exceptionally tender.

Expert Tip for Slicing Beef! Achieving thin, uniform slices is crucial for tenderness and quick cooking. This is easiest when the beef steak is partially frozen. If you’re starting with a completely frozen steak, let it thaw just enough so you can slice it with a sharp knife. If you’re working with fresh beef, pop it into the freezer for about 30 minutes before slicing. Always slice the beef across the grain to shorten the muscle fibers, resulting in a much more tender bite. Aim for slices about 1/4-inch thick and 2-3 inches long.

The Vibrant Broccoli

Broccoli is the perfect companion to the rich, flavorful Mongolian beef sauce. Its slightly bitter notes and crisp texture offer a refreshing contrast to the savory beef. We recommend steaming the broccoli until it’s tender-crisp – still vibrant green with a slight bite, not mushy. While it’s traditionally served alongside the beef in a bowl, you can certainly add the steamed florets to the skillet with the beef during the last minute of cooking if you prefer to mix everything together before serving. This allows the broccoli to soak up some of that delicious sauce.

The Signature Mongolian Sauce Components

The heart of this dish lies in its exquisite sauce. Here are the key ingredients that create its irresistible balance:

  • Soy Sauce: The foundation of umami. Low-sodium soy sauce is highly recommended to give you more control over the saltiness of the dish, preventing it from becoming overly salty while still delivering depth of flavor.
  • Water: Helps to thin out the sauce to the right consistency and allows the flavors to meld beautifully.
  • Fresh Garlic: Minced garlic provides an essential aromatic warmth and pungent flavor that is characteristic of many Asian dishes. Don’t skimp on this!
  • Fresh Ginger: Grated ginger adds a zesty, slightly spicy, and incredibly fragrant note that brightens the entire dish. Fresh is best, but ginger paste can be used in a pinch.
  • Vegetable Oil (for sauce): A small amount of neutral oil helps to carry the fat-soluble flavors and contribute to the sauce’s body.
  • Light Brown Sugar: This is what gives Mongolian beef its signature sweetness, balancing the savory soy sauce and adding a wonderful depth of caramel-like flavor.
  • Cornstarch: The thickening agent for both the beef marinade and the final sauce. When mixed with cold water to form a “slurry,” it creates that glossy, rich texture we all love.
  • Baking Soda (for marinade): A secret weapon for incredibly tender beef. Just a small amount in the marinade helps to break down the beef fibers, ensuring a melt-in-your-mouth texture.
  • Rice Vinegar (for marinade): Adds a subtle tang and brightens the flavors in the marinade, complementing the savory beef.

Step-by-Step Guide: Crafting Your Own Mongolian Beef and Broccoli

Follow these detailed steps to create a truly unforgettable Mongolian Beef and Broccoli dish that will impress everyone.

  1. Prepare and Marinate the Beef: If you’re starting with a whole steak, slice it thinly (about 1/4-inch thick and 3 inches long) across the grain. Place these beef strips into a medium bowl or a sturdy zipper-lock bag. In a separate small bowl or measuring cup, whisk together all the marinade ingredients: baking soda, white sugar, cornstarch, soy sauce, rice vinegar, and vegetable oil until well combined. Pour this marinade over the beef, ensuring every piece is thoroughly coated. Cover the bowl with plastic wrap or seal the bag, then refrigerate for at least 30 minutes. For even more tender and flavorful beef, you can marinate it for up to 8 hours.
  2. Prepare the Sauce Mixture: While the beef is marinating, prepare the delicious Mongolian sauce. In another small bowl or liquid measuring cup, combine the sauce ingredients: low-sodium soy sauce, water, minced garlic, grated fresh ginger, vegetable oil, and light brown sugar. Whisk everything together until the sugar is dissolved and the mixture is uniform. Cover and set this aside for later use. Having both the marinade and sauce ready beforehand streamlines the cooking process.
  3. Cook the Marinated Beef: Heat a large skillet or wok over medium-high heat. Once hot, add the marinated beef in a single layer, ensuring not to overcrowd the pan. If necessary, cook the beef in two batches to achieve a good sear rather than steaming the meat. Cook the beef for 2-3 minutes, stirring and flipping the pieces frequently, just until it is no longer pink and has developed a nice brown crust. Be careful not to overcook the beef, as this can make it tough.

  1. Add the Sauce and Simmer: Once the beef is cooked, pour the prepared sauce mixture directly into the skillet with the beef. Bring the sauce to a gentle boil, stirring occasionally. Reduce the heat slightly and allow the sauce to simmer for about 2-3 minutes. During this time, the flavors will meld together, and the sauce will begin to reduce slightly, intensifying its taste.
  2. Thicken the Sauce to Perfection: In a very small bowl, whisk together the cornstarch and cold water to create a smooth slurry. With the sauce simmering in the skillet, gradually add the cornstarch slurry, a little bit at a time, while continuously stirring. Continue adding until the sauce reaches your desired thickness and achieves a beautiful, glossy sheen. You may not need to use the entire cornstarch mixture; stop once the sauce is perfect for your preference.
  3. Prepare the Broccoli: While the beef and sauce are finishing, steam your broccoli until it’s tender-crisp and bright green. (See “Recipe Notes” for microwave steaming instructions.)
  4. Serve and Garnish: Your Mongolian Beef and Broccoli is now ready! Serve immediately with the steamed broccoli. For a truly complete meal, spoon it over a bed of freshly cooked rice. Garnish with sliced green onions and a sprinkle of sesame seeds for added flavor and visual appeal. Enjoy your homemade, restaurant-quality creation!

Expert Tips for the Best Mongolian Beef and Broccoli

Elevate your Mongolian Beef and Broccoli to new heights with these handy tips and tricks:

  • Optimal Beef Slicing: As mentioned, partially freezing the beef before slicing makes it much easier to cut thin, uniform strips across the grain. This technique is key to achieving that desirable tender texture.
  • Flexible Marination Time: Don’t feel rushed with the marinating. While 30 minutes is sufficient for tenderizing and infusing flavor, letting the beef marinate for up to 8 hours (or even overnight) in the refrigerator will result in an even deeper flavor and more tender beef.
  • Broccoli Your Way: You have options for your broccoli! Serve it separately alongside the beef and sauce, or for a fully integrated dish, toss the steamed broccoli directly into the skillet with the beef and sauce for the last minute of cooking. This allows the florets to absorb some of that incredible flavor.
  • Speedy Microwave Steaming for Broccoli: The microwave is a fantastic tool for quickly steaming broccoli. Simply place the florets in a microwave-safe bowl with about 1-2 tablespoons of water, cover tightly with plastic wrap (or a microwave-safe lid), and microwave on high for 60-90 seconds. Check for tender-crisp doneness; adjust time as needed. Alternatively, a traditional stovetop steamer works perfectly.
  • Scaling the Recipe: This recipe is designed to yield 2-3 servings from 1 lb. of beef, making it ideal for smaller households. If you’re feeding a larger crowd, feel free to easily double or even triple the recipe. Just ensure you use a larger skillet or wok, or cook the beef in batches to avoid overcrowding the pan.
  • Don’t Overcrowd the Pan: When cooking the beef, it’s crucial not to overcrowd your skillet or wok. Overcrowding lowers the pan’s temperature, causing the beef to steam rather than sear, resulting in a less desirable texture. Cook in batches if necessary, ensuring each piece gets direct contact with the hot surface for a beautiful brown crust.
  • Taste and Adjust: Always taste your sauce before and after thickening. Adjust the sweetness with a little more brown sugar, the saltiness with more soy sauce, or add a splash more rice vinegar for tang, if desired. Personalizing the flavor to your preference is key to a truly enjoyable dish.
  • Consider Different Veggies: While broccoli is a classic, don’t hesitate to experiment with other stir-fry friendly vegetables. Sliced bell peppers, carrots, snap peas, or even mushrooms can be wonderful additions, cooked separately or quickly blanched before adding to the skillet.

Prep Time: 10 mins
Cook Time: 15 mins
Marinating Time: 30 mins
Total Time: 55 mins
Yield: 3 servings

Ingredients

  • 1 lb beef stir fry strips, or cut strips from a 1 lb. flank, sirloin, or skirt steak

For the marinade:

  • 1/2 teaspoon baking soda
  • 1 teaspoon white sugar
  • 1 Tablespoon corn starch
  • 1 Tablespoon soy sauce, low-sodium recommended
  • 1 teaspoon rice vinegar
  • 2 Tablespoons vegetable oil, or similar neutral cooking oil

For the sauce:

  • 1/4 cup soy sauce, low-sodium recommended
  • 1/4 cup water
  • 2 teaspoons garlic, minced
  • 1/2 teaspoon fresh ginger, grated, or ginger paste
  • 1 teaspoon vegetable oil, or similar neutral cooking oil
  • 6 Tablespoons light brown sugar

To thicken sauce:

  • 1 1/2 Tablespoons corn starch
  • 1 Tablespoon cold water

To serve:

  • Steamed broccoli, *see Notes for how to steam broccoli
  • Cooked rice, optional

To garnish:

  • Sliced green onions
  • Sesame seeds

Instructions

  1. If starting with a whole steak, slice across the grain into 1/4-inch thick slices, about 3 inches long. Place beef strips into a bowl or a zipper bag.
  2. Make the marinade and sauce: In a small bowl or measuring cup, combine all the marinade ingredients and stir well to combine. While you have the soy sauce and vegetable oil out, go ahead and make the sauce. Combine all the sauce ingredients in a small bowl or measuring cup and stir well. Cover and set aside.
  3. Pour marinade over the beef and stir or shake to coat the beef well. Cover and refrigerate at least 30 minutes or up to 8 hours.
  4. Heat a skillet over medium-high heat on the stovetop. Add the beef and cook, stirring/flipping the pieces, just until the beef is no longer pink. Add the prepared sauce mixture and bring to a boil. Reduce heat slightly and allow to cook a bit more, until the sauce has thickened slightly.
  5. Combine the cornstarch and water in a small bowl. Add to the sauce, a bit at a time, until the sauce is thickened to the desired level. You may not need to use all of the cornstarch mixture.
  6. Serve with steamed broccoli and optionally, with cooked rice.

Notes

If cutting beef strips from a whole steak, you’ll find it easiest to slice thin if the steak is partially frozen. You can either cut while the steak is thawing and still a bit frozen, or if the steak is fresh, pop it in the freezer for 30 minutes before slicing.

The microwave makes short work of steaming broccoli. Simply add to a bowl, cover with plastic wrap and microwave on high for 60-90 seconds, or until tender crisp. Alternately, steam in a steamer on the stove-top.

I like to serve the broccoli alongside the Beef in a bowl, but you could certainly add it to the skillet with the beef at the end of cooking, if you like.

This recipe starts with just 1 lb. of beef and serves 2-3. Feel free to double or triple up if you are feeding more.
