  • Salt and pepper to taste


  • 2 heads of broccoli, cut into florets


  • 1/2 cup of soy sauce
  • 1/4 cup of oyster sauce
  • 2 tablespoons of brown sugar
  • 2 tablespoons of cornstarch
  • 1 teaspoon of sesame oil

Additional Vegetables

  • Optional: You can add other vegetables like bell peppers, carrots, or mushrooms to enhance the flavors and textures of your stir-fry. Feel free to get creative and use your favorite veggies!

Now that we have all our ingredients ready, let’s move on to the preparation process.


Preparing beef and broccoli stir-fry involves a few key steps to ensure that your dish turns out flavorful and tender. So let’s break down each step and get started with marinating the beef.

Marinating the Beef

To make the beef extra tender and flavorful, it’s a good idea to marinate it before cooking. Place the thinly sliced beef in a bowl and season it with salt and pepper to taste. You can also add other spices or marinades of your choice to enhance the flavor. Cover the bowl and let the beef marinate in the refrigerator for at least 30 minutes to allow the flavors to infuse.

Preparing the Sauce

While the beef is marinating, it’s time to prepare the sauce for our stir-fry. In a small bowl, whisk together the soy sauce, oyster sauce, brown sugar, cornstarch, and sesame oil. Make sure to dissolve the cornstarch completely to avoid any lumps in the sauce. Set the sauce aside until we’re ready to use it during the cooking process.

Cutting and Blanching the Broccoli

Next, prepare the broccoli by cutting it into florets. Remove any tough stems and leaves, and keep only the tender parts of the vegetable. Once the broccoli is cut, it’s time to blanch it. Blanching involves briefly boiling the vegetables before cooking them in the stir-fry to ensure that they become tender yet retain their vibrant green color. Bring a pot of water to a boil and add the broccoli florets. Cook them for about 2-3 minutes, then drain and transfer them to a bowl of ice water to stop the cooking process. Once cooled, drain the broccoli and set it aside.

Cooking the Stir-Fry

Now that all the preparations are done, it’s time to cook our beef and broccoli stir-fry. You have two options for cooking methods: the slow cooker method or the stovetop method. Let’s explore both methods and see which one suits your preference.

Slow Cooker Method

If you prefer a hands-off approach to cooking, the slow cooker method is perfect for you. Here’s how you can make beef and broccoli stir-fry using a slow cooker.

Preparing the Slow Cooker

Start by greasing the slow cooker with a cooking spray or by lining it with parchment paper. This will prevent the ingredients from sticking to the sides and make cleaning up easier.

Adding the Ingredients to the Slow Cooker

Place the marinated beef, blanched broccoli, and any additional vegetables you’re using in the slow cooker. Pour the sauce over the ingredients, ensuring that everything is well-coated. Give the mixture a gentle stir to distribute the sauce evenly.

Cooking and Serving

Cover the slow cooker and cook the stir-fry on low heat for about 4-6 hours or on high heat for 2-3 hours, depending on your desired tenderness. Once the beef is cooked to your liking and the flavors have melded together, it’s time to serve the dish. You can enjoy the beef and broccoli stir-fry over steamed rice or noodles for a complete and satisfying meal.

Stovetop Method

If you prefer a quicker cooking time and enjoy the hands-on process of stir-frying, the stovetop method is the way to go. Let’s dive into the stovetop method of making beef and broccoli stir-fry.

Marinating the Beef

Follow the same steps for marinating the beef as mentioned earlier. Allow the beef to marinate in the refrigerator for at least 30 minutes before continuing with the stir-fry process.

Preparing the Stir-Fry Sauce

Just like the slow cooker method, whisk together the soy sauce, oyster sauce, brown sugar, cornstarch, and sesame oil in a small bowl. Set the sauce aside until we’re ready to use it.

Stir-Frying the Ingredients

Heat a wok or a large skillet over medium-high heat and add some cooking oil. Once the oil is hot, add the marinated beef and stir-fry for 2-3 minutes, or until it’s nicely browned. Remove the beef from the wok and set it aside.

In the same wok, add the broccoli florets and any additional vegetables. Stir-fry them for a few minutes until they are tender yet still slightly crisp. Return the beef to the wok and pour the sauce over the ingredients. Stir-fry everything together for another minute or until the sauce thickens and coats the ingredients evenly.

Serving the Dish

Once the beef and broccoli stir-fry is cooked to perfection, it’s time to serve the dish. You can garnish it with some sesame seeds or chopped green onions for added flavor and presentation. Serve the stir-fry over steamed rice or noodles, and enjoy the delicious combination of flavors and textures.

Tips for Success

To ensure that your beef and broccoli stir-fry turns out perfectly every time, here are some tips to keep in mind:

Choosing the Right Cut of Beef

When it comes to stir-frying beef, it’s important to choose a cut that is tender and flavorful. Opt for cuts like flank steak, sirloin, or ribeye, as they tend to work well in stir-fries. Be sure to cut the beef against the grain to ensure tenderness.

Properly Blanching the Broccoli

Blanching the broccoli helps to preserve its vibrant green color and crisp texture. Make sure not to overcook the broccoli during the blanching process, as it will continue to cook when stir-fried. The goal is to have slightly tender yet still crisp broccoli florets.

Adjusting the Sauce to Taste

The sauce is what brings all the flavors together in a beef and broccoli stir-fry. Feel free to adjust the amount of soy sauce, brown sugar, or other seasonings based on your personal preference. If you prefer a sweeter dish, add a bit more brown sugar. If you like it spicier, add some chili flakes or a dash of hot sauce. Don’t be afraid to experiment and make the dish your own.

Adding Additional Vegetables

While beef and broccoli are the star ingredients of this stir-fry, you can always customize it by adding other vegetables of your choice. Bell peppers, carrots, onions, or mushrooms are all great options that can add extra color, flavor, and nutrients to the dish. Just make sure to adjust the cooking time accordingly, as different vegetables may require different cooking times.


To switch things up and add some excitement to your beef and broccoli stir-fry, here are a few variations you can try:

Spicy Beef and Broccoli Stir-Fry

If you’re a fan of heat, add some red chili flakes, diced jalapeƱos, or a spicy sauce like sriracha to your stir-fry. The spicy kick will elevate the flavors and give your dish a little extra zing.

Garlic Beef and Broccoli Stir-Fry

For garlic lovers, a garlic-infused version of beef and broccoli stir-fry is a must-try. Simply mince a few cloves of garlic and add them to the stir-fry during the cooking process. The aroma and flavor of garlic will take this dish to another level.

Teriyaki Beef and Broccoli Stir-Fry

For a sweet and savory twist, try making a teriyaki version of beef and broccoli stir-fry. Replace the oyster sauce in the sauce recipe with teriyaki sauce, and you’ll have a deliciously sticky and flavorful dish.

Feel free to get creative and experiment with different flavors and ingredients to find your favorite variation of beef and broccoli stir-fry.

Health Benefits

Beef and broccoli stir-fry not only tastes amazing, but it also offers several health benefits. Here are a few reasons why you should include this dish in your meal rotation:

Protein from Beef

Beef is an excellent source of high-quality protein, which is essential for building and repairing tissues, supporting muscle growth, and maintaining a healthy immune system. By including beef in your stir-fry, you’re adding a good amount of protein to your meal.

Vitamins and Fiber from Broccoli

Broccoli is a nutrient-dense vegetable packed with vitamins like vitamin C, vitamin K, and vitamin A, as well as fiber, which aids in digestion and helps you feel fuller for longer. By incorporating broccoli into your stir-fry, you’re boosting the nutritional value of your meal.

Low-Carb and Gluten-Free Options

If you’re following a low-carb or gluten-free diet, beef and broccoli stir-fry is a great option. By skipping the rice or noodles and serving the stir-fry on its own, you can enjoy a delicious and nutritious meal that fits your dietary needs.


As with any recipe, there may be some questions that arise. Here are answers to a few commonly asked questions about beef and broccoli stir-fry:

Can I use frozen broccoli?

While fresh broccoli is preferred for its vibrant color and crisp texture, you can certainly use frozen broccoli in this stir-fry. Just make sure to thaw and drain the frozen broccoli before adding it to the dish. Keep in mind that frozen broccoli may be slightly softer compared to fresh broccoli.

Can I use chicken instead of beef?

Absolutely! If you prefer chicken over beef, you can easily substitute it in this recipe. Thinly sliced chicken breast or thigh meat works well in a stir-fry and can be cooked using the same methods outlined in this article.

Can I substitute the soy sauce with another ingredient?

If you have dietary restrictions or simply prefer a different flavor profile, you can substitute the soy sauce with alternative ingredients like tamari, coconut aminos, or a homemade low-sodium soy sauce alternative. These options can provide a similar umami flavor without the added sodium content.
