Save This comforting slow-cooked dish features thinly sliced flank steak that becomes incredibly tender after hours in the crock pot, paired with vibrant broccoli florets. The savory sauce combines low-sodium soy sauce, beef broth, brown sugar, and aromatic garlic and ginger for rich Chinese-American flavors.
Simply coat the beef in cornstarch, pour over the whisked sauce, and let your slow cooker do the work. Add fresh broccoli during the last 30 minutes for perfect texture. Serve over steamed rice with optional sesame seeds and green onions.
The kitchen timer beeped somewhere in the distance while I wrestled with takeout containers, again. That Tuesday evening when my slow cooker transformed into my dinner savior, this beef and broccoli recipe became our weekly rotation hero. Something about walking through the door to that garlic soy aroma makes everyone gravitate toward the kitchen.
My neighbor actually knocked on my door asking what smelled so amazing the first time I made this. Now it is the most requested dish for every family gathering and potluck.
Ingredients

Instructions

Save This dish has officially replaced our Friday takeout habit, and honestly nobody misses the delivery fees.
Make It Your Own
Swap in chicken thighs or shrimp for a lighter protein option, just adjust your cooking time down for shrimp so they do not get rubbery tough.
The Rice Game
Day old rice actually works best here if you have it, but fresh steamed rice soaks up that sauce like nothing else.
Prep Ahead Magic
Everything can be assembled the night before and kept in the refrigerator, then just turn on your slow cooker before heading out for the day.
- Cut your beef the night before and store it coated in cornstarch
- Mix your sauce in a jar and shake it up right before pouring
- Bag your broccoli florets separately so they stay crisp until cooking time
Save Nothing beats coming home to a meal that tastes like you spent all day cooking when it really did all the work itself.
Recipe FAQs
- → What cut of beef works best?
-
Flank steak or sirloin sliced thinly against the grain yields the most tender results. The slow cooking process breaks down connective tissues, making even lean cuts wonderfully tender.
- → Can I make this gluten-free?
-
Yes, substitute tamari or coconut aminos for soy sauce and ensure your oyster sauce is certified gluten-free. Cornstarch is naturally gluten-free but always verify labels.
- → How do I prevent broccoli from overcooking?
-
Add broccoli florets during the final 25-30 minutes of cooking time. This keeps them bright green and tender-crisp rather than mushy. Frozen broccoli works too but may need slightly longer.
- → Can I cook this on high heat?
-
Cook on high for 2 hours instead of 4 hours on low. The beef will still become tender, though low-and-slow cooking typically yields more succulent results. Adjust broccoli timing accordingly.
- → What sides complement this dish?
-
Steamed white or brown rice is traditional. You could also serve over cauliflower rice for low-carb meals, or with Asian noodles. Extra steamed vegetables like snap peas or bell peppers make great additions.
- → How long do leftovers keep?
-
Store in an airtight container in the refrigerator for 3-4 days. The sauce helps keep the beef moist when reheating. Avoid adding broccoli until serving leftovers to maintain texture.
