Ingredients
- 1.5 lbs flank steak, sliced thinly against the grain
Flank steak is a lean cut of beef that benefits from the slow cooking process, becoming tender and flavorful as it cooks in the crockpot. Slicing it thinly against the grain ensures that each piece remains tender and easy to chew. - 4 cups broccoli florets
Broccoli adds both nutrition and color to the dish. When added towards the end of the cooking process, it retains a vibrant green color and a slight crunch, balancing the tender beef. - 1/2 cup soy sauce
Soy sauce is the base of the sauce, contributing a rich umami flavor that enhances the beef and vegetables. It also helps to tenderize the meat as it cooks. - 1/4 cup brown sugar
The brown sugar provides sweetness that counters the saltiness of the soy sauce, creating a more rounded flavor profile. It also aids in caramelizing the beef. - 2 tablespoons sesame oil
Sesame oil adds a nutty flavor that complements the other ingredients, enhancing the overall taste of the dish. It's rich in antioxidants and gives the sauce a luxurious texture. - 3 cloves garlic, minced
Garlic is a staple in many Asian dishes, providing a fragrant aroma and depth to the flavor. It infuses the meat and vegetables with its distinct sharpness. - 1 teaspoon ground ginger
Ginger adds warmth and a hint of spice, balancing out the savory and sweet notes of the dish. It's also beneficial for digestion. - 2 tablespoons cornstarch mixed with 2 tablespoons water (slurry)
This cornstarch slurry acts as a thickening agent, turning the sauce into a luscious coating for the beef and broccoli. It ensures that the sauce clings to the ingredients.
Directions & Preparation
Step 1: Prepare the beef
Start by slicing the flank steak into thin strips against the grain. This is crucial as it ensures the meat remains tender after cooking. Thin slices allow the flavors from the sauce to penetrate more thoroughly, ensuring each bite is infused with taste.
Step 2: Make the sauce
In a mixing bowl, combine the soy sauce, brown sugar, sesame oil, minced garlic, and ground ginger. Whisk until well blended. This mixture will serve as the base for flavoring the beef and broccoli, so spend a little extra time ensuring it's well incorporated; this will help every ingredient shine.
Step 3: Add ingredients to the crockpot
Layer the sliced beef in the bottom of the crockpot and pour the sauce over the top. It's important to ensure that the beef is evenly coated to maximize flavor absorption during cooking. This method also allows the beef to marinate while it cooks.
Step 4: Cook on low
Cover and cook the mixture on low for 4-6 hours. Keeping the heat low ensures that the meat becomes tender without drying out, while the lengthy cooking time allows the flavors to meld, resulting in a rich and savory dish.
Step 5: Prepare broccoli
About 30 minutes before the cooking time is complete, add the broccoli florets to the crockpot. This timing ensures that they cook through but remain crisp. Overcooked broccoli can become mushy and lose its vibrant color, so timing is key.
Step 6: Thicken the sauce
In a small bowl, mix 2 tablespoons of cornstarch with 2 tablespoons of water to create a slurry. After adding the broccoli, stir this mixture into the crockpot to thicken the sauce. This step enhances the dish's texture, making it more enjoyable to eat.
Step 7: Serve your dish
Once the sauce has thickened and the broccoli is cooked to your liking, it's time to serve. Ladle the beef and broccoli over a bed of rice or noodles, soaking up the delicious sauce. Garnish with sesame seeds or chopped green onions for added flavor and presentation.

Choosing the Right Cut of Beef
Selecting the right cut of beef is vital for a tender and flavorful dish. Flank steak is ideal due to its lean composition, which becomes tender during the slow cooking process. If flank steak isn’t available, you can substitute with sirloin or chuck roast, but remember that cooking times may vary slightly based on the cut. Always slice against the grain to enhance tenderness.
The Importance of Broccoli Timing
Adding the broccoli florets at the right time makes a significant difference in texture and flavor. If added too early, they may become mushy and lose their bright color. By waiting until the last 30 minutes of cooking, the broccoli remains crunchy and vibrant, providing a nice contrast to the tender beef and rich sauce. This technique not only retains nutrients but also makes for a visually appealing dish.
Customization for Personal Taste
This recipe is incredibly adaptable, allowing you to include other vegetables or adjust the sauce to suit your preferences. Consider adding bell peppers, carrots, or snap peas for added color and flavor. For a spicier kick, add crushed red pepper flakes or chili paste. The versatility of this dish means it can cater to a wide variety of tastes and dietary needs, making it a fantastic option for family dinners.
FAQs
What if the beef turns out tough?
If the beef is tough, it may not have been cooked long enough. Ensure that you cook on low for the full 4-6 hours to allow the beef to tenderize properly.
How can I adjust the sauce flavor?
To adjust the sauce flavor, consider adding more brown sugar for sweetness or more soy sauce for saltiness. Start with small increments to avoid overpowering the dish.
Why is my sauce too thin?
If the sauce is too thin, you can thicken it further by mixing a bit more cornstarch with water and adding it back to the crockpot during the last 30 minutes of cooking.
Could I use different vegetables?
Absolutely! You can incorporate vegetables like bell peppers or snap peas, adjusting the cooking time accordingly to prevent overcooking.
What if I want a milder dish?
For a milder flavor, reduce the amount of soy sauce and garlic. You can also omit the ginger or replace it with less spicy alternatives.
How do I know when the cooking time is right?
The cooking time is typically four to six hours on low. Check the beef; it should be fork-tender, and the broccoli should be vibrant and tender yet crisp.
