Ingredients
- 1 1/2 pounds beef sirloin or flank steak, thinly sliced against the grain
- 1 cup low-sodium beef broth
- 1/2 cup low-sodium soy sauce
- 1/3 cup dark or light brown sugar
- 1 tablespoon sesame oil
- 3 teaspoons (about 3 cloves) minced garlic
- 2 tablespoons cornstarch
- 3 cups (about 1, 12-oz bag) broccoli florets (fresh or frozen)
- 1–2 tablespoons Sriracha or chili garlic sauce (optional, for spice)
- 2–3 green onions, thinly sliced
- Cooked jasmine or white rice, for serving
- Sesame seeds, for garnish (optional)
Equipment Needed
- 4- to 7-quart slow cooker or crockpot
- Sharp chef’s knife
- Mixing bowls
- Whisk
- Measuring cups and spoons
Instructions
- Prep the Beef: Slice the beef against the grain into quarter-inch strips. Place the beef strips directly into the base of the slow cooker.
- Mix the Sauce: In a medium bowl, whisk together the beef broth, soy sauce, brown sugar, sesame oil, minced garlic, green onions, and Sriracha (if using). Make sure the brown sugar is dissolved and ingredients are well-blended.
- Combine and Cook: Pour the sauce mixture over the beef in the slow cooker. Stir or toss gently to coat the meat evenly. Cover with the lid and set the slow cooker to cook on LOW for 3.5 to 4 hours, or until the beef is very tender and fully cooked.
- Thicken the Sauce: Once the beef is done, ladle out a few tablespoons of the hot broth into a small bowl. Whisk together with cornstarch until smooth—this is your slurry.
- Return the Slurry: Pour the slurry back into the slow cooker and stir well. This will help thicken the sauce as it heats up.
- Add the Broccoli: Add the broccoli florets (frozen is fine) to the slow cooker, nestling them into the beef and sauce. Place the lid back on and cook for an additional 20–30 minutes, until the broccoli is just tender and the sauce is glossy and thickened.
- Serve: Spoon the beef and broccoli over bowls of cooked jasmine rice. Garnish with extra green onions and a sprinkle of sesame seeds, if you wish.

Tips for Best Results
- Slice the beef against the grain for the most tender texture.
- For extra flavor, briefly sear the beef in a skillet before adding to the slow cooker (optional).
- If using frozen broccoli, it can be added straight from the freezer. For softer broccoli, thaw slightly or add earlier.
- Let the cornstarch slurry fully dissolve before stirring back into the cooker to avoid lumps.
- Customize the sauce—add more Sriracha for heat, extra brown sugar for sweetness, or a dash of ginger for brightness.
- Make this dish gluten-free by using gluten-free soy sauce (tamari) and checking your other ingredients.
Variations and Add-Ins
- Vegetable Medley: Toss in snow peas, water chestnuts, or sliced red bell peppers along with the broccoli for more color and crunch.
- Garlic-Lover’s Version: Double the garlic for an extra pungent punch.
- Sweet & Spicy Blend: Use honey instead of brown sugar and increase the chili sauce.
- Low-Carb Option: Serve over cauliflower rice and reduce the brown sugar to taste.
Expert Advice: Common Mistakes to Avoid
- Do not overcook the broccoli—add it only in the last 20 to 30 minutes to keep it vibrant.
- Resist lifting the lid unnecessarily, as this can noticeably reduce cooking efficiency and delay cooking times.
- Make sure the beef is fully submerged in sauce for the most even cooking and flavor absorption.
- If your sauce isn’t thickening, add a little more cornstarch slurry in small increments and simmer a bit longer.
Serving Suggestions
- Steamed white or jasmine rice is classic, but brown rice or quinoa offer healthy alternatives.
- For a fun twist, serve the beef and broccoli in lettuce cups for a carb-conscious lunch.
- Top with toasted sesame seeds and a drizzle of extra sesame oil for enhanced fragrance.
- Pair with crispy wontons, spring rolls, or a simple Asian-style slaw for a complete meal.
Storage and Reheating
- Refrigerate: Store cooled leftovers in an airtight container for up to 4 days.
- Freeze: Beef and broccoli (without rice) can be frozen for up to 3 months. Thaw overnight and reheat gently in a pan or microwave.
- Reheat: Add a splash of beef broth or water when reheating to keep the sauce silky and prevent dryness.
Frequently Asked Questions

Chef’s Tips For Next-Level Beef and Broccoli
- Use fresh broccoli for the best texture, but frozen works well for convenience.
- If you enjoy a sauce with extra zing, add 1 tablespoon minced fresh ginger during the initial mixing step.
- Taste and adjust the sauce after slow cooking, adding soy sauce, sugar, or chili sauce to dial in your preferred flavor.
- If your broccoli is extra large, cut any thick stems into smaller pieces so they cook evenly.
Nutritional and Dietary Considerations
This dish is high in protein, offers a solid serving of fiber and vitamins from the broccoli, and can be made gluten-free or lower-carb with minor adjustments. Reducing the amount of brown sugar or serving with a whole grain will improve its nutritional profile without sacrificing taste.
