Slow Cooker Beef and Broccoli is a delicious homemade dinner that brings all the savory, slightly sweet flavors of your favorite takeout meal straight to your kitchen. Tender slices of beef slowly cook in a rich garlic, ginger, and soy sauce mixture until flavorful and easy to bite into. Fresh broccoli is added near the end, keeping it bright green and perfectly tender.
The sauce is what makes this dish so special. A combination of low-sodium soy sauce, brown sugar, rice vinegar, sesame oil, and fresh aromatics creates a glossy, flavorful coating that pairs beautifully with the beef and broccoli.
Best of all, your slow cooker does most of the work. Serve this comforting meal over steamed rice or noodles for an easy weeknight dinner the whole family can enjoy.

Ingredients You’ll Need
Beef flank steak or top sirloin: Thinly sliced beef works beautifully in this recipe. Slice against the grain for a more tender bite.
Fresh broccoli florets: Add them toward the end of cooking so they don’t become overly soft.
Low-sodium soy sauce: Creates the savory foundation of the sauce without making it excessively salty.
Beef broth: Adds extra beefy flavor and helps form the cooking liquid.
Light brown sugar: Provides sweetness that balances the salty soy sauce and tangy vinegar.
Rice vinegar: Adds a mild acidity that brightens the sauce.
Sesame oil: Gives the dish its distinctive nutty aroma and flavor.
Fresh ginger: Adds warmth and a fresh, slightly spicy taste.
Garlic: Brings savory depth to the sauce.
Black pepper: Adds gentle seasoning.
Red pepper flakes: Optional, but perfect if you enjoy a little heat.
Cornstarch and cold water: Combine to make a slurry that thickens the sauce into a glossy coating.
Toasted sesame seeds and green onions: Add a fresh, crunchy garnish before serving.
Vegetable oil: Optional, for searing the beef before slow cooking.
How to Make Slow Cooker Beef and Broccoli
Step 1: Prepare the Beef
Pat the beef slices dry with paper towels. Slice the meat thinly against the grain to help keep it tender.
For extra flavor, heat the vegetable oil in a large skillet over medium-high heat. Sear the beef for 2–3 minutes per side until lightly browned. This step is optional, but it adds a deeper, richer flavor.
Transfer the beef to the bottom of your slow cooker.
Step 2: Make the Sauce
In a medium bowl, whisk together the low-sodium soy sauce, beef broth, brown sugar, rice vinegar, sesame oil, grated ginger, minced garlic, black pepper, and red pepper flakes if using.
Stir until the brown sugar is dissolved and everything is well combined.
Step 3: Combine Everything in the Slow Cooker
Pour the prepared sauce over the beef, making sure most of the meat is covered by the liquid.
Give everything a gentle stir to distribute the sauce evenly.
Step 4: Slow Cook the Beef
Cover the slow cooker and cook on LOW for 4–6 hours or HIGH for 2–3 hours, until the beef is tender and easy to pull apart with a fork.
Cooking times can vary depending on the thickness of the beef and your slow cooker.
Step 5: Add the Broccoli
When approximately 30–45 minutes of cooking time remain, stir the fresh broccoli florets into the slow cooker.
Cover again and continue cooking until the broccoli is tender-crisp and bright green.
Avoid adding the broccoli too early, as extended cooking can make it mushy.
Step 6: Thicken the Sauce
In a small bowl, whisk together the cornstarch and cold water until smooth.
Carefully remove about 1/2 cup of hot cooking liquid from the slow cooker and whisk it into the cornstarch mixture.
Pour the tempered slurry back into the slow cooker, stirring to combine.
Cook on HIGH for another 15–20 minutes, until the sauce thickens to your preferred consistency.
Step 7: Garnish and Serve
Taste the sauce and adjust the seasoning if needed. Add more soy sauce for saltiness, brown sugar for sweetness, or rice vinegar for extra tang.
Serve the beef and broccoli over steamed white rice, brown rice, or noodles. Finish with toasted sesame seeds and sliced green onions.
Tips for the Best Beef and Broccoli
- Slice against the grain: This is one of the easiest ways to make beef more tender.
- Choose the right cut: Flank steak and top sirloin are excellent options for this recipe.
- Sear for extra flavor: Although optional, browning the beef creates a richer flavor.
- Add broccoli near the end: Cooking it for the final 30–45 minutes helps preserve its texture and color.
- Use cold water for the slurry: Cornstarch mixes more smoothly with cold water and helps prevent lumps.
- Adjust the sauce: Taste before serving and balance the sweetness, saltiness, and acidity to your liking.
- Don’t overcook the broccoli: Check it toward the end so it stays tender-crisp.
Easy Variations
Make It Spicier: Increase the red pepper flakes or add a little sriracha to the sauce for extra heat.
Add More Vegetables: Include sliced carrots or bell peppers for additional color, flavor, and texture.
Use Different Beef Cuts: Beef chuck, stew meat, or thinly sliced round steak can also work. Tougher cuts may need additional cooking time.
Add Extra Garlic and Ginger: Increase the garlic or ginger if you enjoy a stronger, more aromatic sauce.
Try a Low-Carb Serving: Serve over cauliflower rice or zucchini noodles instead of traditional rice or pasta.
Add an Extra Umami Flavor: A little oyster sauce can add another layer of savory flavor to the sauce.

How to Store and Reheat Leftovers
Refrigerator: Allow leftovers to cool promptly and transfer them to an airtight container. Refrigerate within 2 hours and enjoy within 3–4 days.
Freezer: Place cooled portions in freezer-safe containers or bags. Freeze for up to 2–3 months for best quality.
Thawing: Thaw frozen portions overnight in the refrigerator before reheating.
Microwave: Place an individual portion in a microwave-safe dish, cover loosely, and heat in short intervals, stirring halfway through, until thoroughly heated.
Stovetop: Warm the beef and broccoli in a skillet or saucepan over medium-low heat. Add a splash of beef broth or water if the sauce has become too thick.
Avoid overheating the broccoli during reheating, as it can become too soft.
Frequently Asked Questions
Can I use a different cut of beef?
Yes. Flank steak and top sirloin are recommended, but chuck roast, stew meat, and round steak can also work. Tougher cuts may need extra time to become tender.
