Ingredients

For the Beef

1½ pounds (680 g) beef chuck roast or flank steak, thinly sliced
¾ cup low-sodium soy sauce
½ cup beef broth
⅓ cup packed brown sugar
1 tablespoon sesame oil
4 cloves garlic, minced
1 tablespoon fresh ginger, finely grated
1 tablespoon rice vinegar
1 tablespoon cornstarch
2 tablespoons cold water
4 cups fresh broccoli florets

For Serving

Cooked white or brown rice
Sliced green onions
Sesame seeds
Optional: red pepper flakes for heat

How to Make Slow Cooker Beef & Broccoli

Step 1: Prepare the Beef

Trim away any large pieces of excess fat from the beef.

Slice the meat thinly against the grain. Thin slices cook more evenly and are easier to eat once tender.

If you’re having trouble slicing the beef thinly, place it in the freezer for about 20–30 minutes first. It will firm up slightly and become much easier to slice.

Step 2: Make the Sauce

In a bowl, whisk together:

Soy sauce
Beef broth
Brown sugar
Sesame oil
Minced garlic
Fresh ginger
Rice vinegar

Whisk until the brown sugar is mostly dissolved.

Step 3: Add Everything to the Slow Cooker

Place the sliced beef into your slow cooker.

Pour the sauce over the beef and gently toss everything together.

Cover with the lid.

Step 4: Slow Cook

Cook on:

LOW for 4–6 hours

HIGH for 2–3 hours

Cooking time can vary depending on the thickness and cut of the beef, so avoid relying only on the clock. The beef should be tender when finished.

Step 5: Thicken the Sauce

About 20–30 minutes before serving, whisk together:

1 tablespoon cornstarch + 2 tablespoons cold water

to make a smooth slurry.

Stir it into the sauce in the slow cooker.

Cover and continue cooking until the sauce thickens.

Step 6: Add the Broccoli

Add the fresh broccoli florets during the last 20–30 minutes of cooking.

Stir gently so the broccoli becomes coated in the sauce.

Cook just until the broccoli reaches your preferred tenderness.

For brighter, crisper broccoli, don’t add it too early. Cooking it for the entire slow-cooking period can leave it overly soft.

Step 7: Serve

Spoon the beef and broccoli over hot cooked rice.

Finish with sliced green onions and sesame seeds.

For a little heat, sprinkle with red pepper flakes.

Serve immediately and enjoy!

🥩 Best Beef for Slow Cooker Beef & Broccoli

Several cuts can work well.

Chuck Roast

Chuck becomes wonderfully tender with slow cooking and is a good choice if you want very soft, flavorful beef.

Flank Steak

Flank steak has a strong beefy flavor and works particularly well when sliced thinly against the grain.

Sirloin

Sirloin is leaner and can also be used, although it shouldn’t be overcooked because it can become less tender.

Tip

Whatever cut you choose, slicing the meat properly makes a big difference.

Look for the direction of the muscle fibers and cut across them rather than along them.

🥦 How to Keep the Broccoli From Getting Mushy

This is one of the most important tricks in the recipe!

Don’t put the broccoli into the slow cooker at the beginning.

Instead, add it toward the end.

Fresh broccoli only needs a relatively short cooking time to become tender. Adding it during the final 20–30 minutes helps preserve its color, texture, and flavor.

If you prefer very crisp broccoli, you can even steam it separately and stir it into the finished beef and sauce just before serving.

🌶️ Easy Ways to Customize It

Want to change things up?

Try adding:

For heat:
Red pepper flakes, chili garlic sauce, or a little sriracha.

For extra flavor:
A splash of toasted sesame oil at the end.

For sweetness:
A little extra brown sugar or honey.

For vegetables:
Sliced bell peppers, mushrooms, snow peas, or carrots.

For crunch:
Cashews or chopped peanuts.

🥡 Storage and Reheating

Allow leftovers to cool and refrigerate them in a covered container within 2 hours.

Store the beef and broccoli in the refrigerator for up to 3–4 days.

For longer storage, freeze the beef and sauce in a freezer-safe container. The broccoli may soften somewhat after freezing and reheating.

Reheat leftovers thoroughly until steaming hot.

If the sauce becomes too thick after refrigeration, add a small splash of beef broth or water while reheating.
