This slow cooker beef and broccoli transforms tough chuck roast into melt-in-your-mouth tender meat alongside crisp broccoli florets, all swimming in a rich garlic soy sauce that rivals your favorite takeout spot. My family requests this dish weekly because it gives us restaurant-quality Chinese American flavors with minimal effort.
I first created this recipe when I was craving Chinese takeout during a particularly busy week. The slow cooker did all the work while I handled other tasks, and now it's become our go-to solution for satisfying Asian food cravings without the delivery fees.
Ingredients
- Boneless beef chuck roast: Offers the perfect balance of fat and meat that becomes incredibly tender during slow cooking. Look for well-marbled pieces for the best flavor.
- Low sodium beef broth: Creates a flavorful base without making the final dish too salty. The better quality broth you use, the richer your sauce will be.
- Low sodium soy sauce: Provides that classic umami flavor. Using low sodium allows you to control the salt level in the finished dish.
- Dark brown sugar: Balances the saltiness with subtle sweetness and helps create that glossy sauce texture. The molasses notes add complexity regular sugar just cannot match.
- Sesame oil: Delivers authentic Asian flavor with just a small amount. Always buy pure sesame oil and store it in the refrigerator to maintain freshness.
- Minced garlic: Infuses the sauce with aromatic depth. Fresh garlic provides the strongest flavor, but jarred works in a pinch.
- Cornstarch: Transforms the thin cooking liquid into that classic thick, glossy sauce that clings beautifully to the beef and broccoli.
- Frozen broccoli florets: Maintain their shape and vibrant color. The convenience factor is unbeatable, though fresh works wonderfully too if you prefer.
Step-by-Step Instructions
- Prepare the sauce:
- Whisk together beef broth, soy sauce, brown sugar, sesame oil, and minced garlic in a medium bowl until the sugar completely dissolves. This balanced mixture creates the foundation of flavor that will penetrate the meat during the long cooking process.
- Load the slow cooker:
- Place your thinly sliced beef chuck into the slow cooker and pour the prepared sauce over it, making sure to toss the meat thoroughly. Every piece should be coated to ensure even flavor development throughout the cooking time.
- Slow cook the beef:
- Set your slow cooker to LOW and let it work its magic for 2.5 to 3.5 hours. The low, gentle heat breaks down the tough connective tissues in the chuck roast, resulting in incredibly tender meat without drying it out.
- Thicken the sauce:
- About an hour before cooking is complete, remove a small portion of the cooking liquid and mix it with cornstarch in a separate bowl. This slurry should be completely smooth before slowly stirring it back into the slow cooker to prevent lumps from forming in your sauce.
- Add the broccoli:
- During the final 30 minutes of cooking, add the frozen broccoli florets and stir them into the thickened sauce. This timing ensures the broccoli retains a pleasing crisp-tender texture rather than becoming mushy.
- Serve with style:
- Transfer your beef and broccoli to serving plates alongside fluffy white rice. The contrast between the savory meat, vibrant green broccoli, and neutral rice creates a perfectly balanced meal.

The dark brown sugar in this recipe is my secret weapon. I once made this with light brown sugar in a pinch, and my family immediately noticed the difference. The deeper molasses notes in dark brown sugar create a more authentic flavor profile that really makes this dish special. My daughter actually requests this meal for her birthday dinner every year instead of going out to eat!
Perfect Rice Pairings
White jasmine rice is the classic accompaniment to beef and broccoli, absorbing the flavorful sauce perfectly. For best results, rinse your rice thoroughly before cooking to remove excess starch. This creates fluffier grains that separate beautifully rather than clumping together. For a healthier option, brown rice offers more fiber and nutrients, though it requires a longer cooking time. I sometimes serve this over cauliflower rice when we want a lower-carb meal without sacrificing the experience.
Make-Ahead Options
This beef and broccoli actually improves with time as the flavors continue to meld. You can prepare the entire dish up to two days ahead and store it in the refrigerator. When reheating, add a splash of water or broth if the sauce has thickened too much. For busy weeks, prepare several batches and freeze individual portions for up to three months. The texture of the broccoli will soften slightly when frozen and reheated, but the flavor remains excellent.
Customization Ideas
The basic recipe works beautifully as written, but there are many ways to adapt it to your preferences. For a spicier version, add red pepper flakes or a tablespoon of sriracha to the sauce mixture. Mushrooms make an excellent addition when added during the last hour of cooking. Fresh ginger adds brightness when grated into the sauce mixture. For a more authentic restaurant-style dish, add a teaspoon of Chinese five-spice powder to the sauce.
Recipe FAQs
- → Can I use fresh broccoli instead of frozen?
Yes, fresh broccoli works perfectly! Add it during the last 20-30 minutes of cooking time to maintain a crisp-tender texture. If you prefer softer broccoli, you can add it earlier, around 45 minutes before the dish is finished.
- → What cut of beef works best for this slow cooker dish?
Chuck roast is ideal because it becomes tender during slow cooking. You could also use flank steak, sirloin, or round steak. The key is cutting the beef into thin, uniform strips to ensure even cooking.
- → How can I make this dish less salty?
The recipe already calls for low-sodium beef broth and soy sauce to control salt levels. For even less sodium, you could dilute the beef broth with water or use coconut aminos as a substitute for some or all of the soy sauce.
- → Can I prepare this as a freezer meal?
Yes! Combine the beef and sauce ingredients in a freezer bag and freeze for up to 3 months. Thaw overnight in the refrigerator before cooking. Add the cornstarch slurry and broccoli as directed in the original instructions.
- → What sides pair well with beef and broccoli?
White rice is traditional, but you could also serve it with brown rice, cauliflower rice, or noodles. For a complete meal, add egg rolls, spring rolls, or a simple cucumber salad with rice vinegar dressing.
- → How can I thicken the sauce if it's too thin?
If your sauce needs additional thickening after adding the cornstarch slurry, make another small batch with 1 tablespoon cornstarch and 2 tablespoons cold water. Add it to the slow cooker, stir well, and cook uncovered on HIGH for 10-15 minutes.
