Make easy Slow Cooker Beef and Broccoli! This simple recipe features tender beef and broccoli in a savory-sweet sauce.

Ingredients

Scale

Here’s the complete list of ingredients, with precise measurements:

  • 1.5 lbs beef flank steak, thinly sliced (Strongly consider substituting 1.5 lbs beef chuck, cut into 1-inch cubes for better results with slow cooking)
  • 4 cups broccoli florets
  • 1/2 cup soy sauce (low sodium recommended)
  • 1/4 cup brown sugar, packed
  • 1/4 cup beef broth
  • 3 cloves garlic, minced
  • 1 tsp ginger, grated
  • 1 tbsp cornstarch (optional, for thickening)
  • Cooked rice, for serving
  • Sesame seeds, for garnish
  • (Implied: 1-2 tbsp cold water for cornstarch slurry if using)

These quantities create a good amount of sauce for the beef and broccoli.

Instructions

Let’s walk through this easy slow cooker process, keeping the beef choice in mind:

1. Combine Beef and Sauce in Slow Cooker:

  • Thinly slice the flank steak against the grain (or use cubed chuck roast).
  • In the insert of your slow cooker, combine the sliced beef, soy sauce, brown sugar, beef broth, minced garlic, and grated ginger.
  • Stir everything together well to ensure the beef is evenly coated with the sauce ingredients.

2. Cook the Beef:

  • Cover the slow cooker securely with the lid.
  • Cook on the LOW heat setting for 4-5 hours OR on the HIGH heat setting for 2-3 hours. This timing is appropriate for flank steak to just cook through, but may not fully tenderize chuck. If using chuck roast, cook on LOW for 6-8 hours until tender. The goal is tender beef.

3. Add Broccoli and Thicken Sauce (Optional):

  • About 30 minutes before the end of the cooking time, add the broccoli florets to the slow cooker. Stir gently to incorporate them into the sauce.
  • (Optional Thickening): If you desire a thicker sauce, whisk the 1 tablespoon of cornstarch with 2 tablespoons of cold water in a small bowl until smooth. Stir this slurry into the liquid in the slow cooker.

4. Finish Cooking:

  • Replace the lid and continue cooking for the final 30 minutes, or until the broccoli is tender-crisp and the sauce has thickened slightly (if using cornstarch).

5. Serve:

  • Serve the hot Slow Cooker Beef and Broccoli immediately over cooked rice.
  • Garnish generously with sesame seeds before serving.
