Ingredients

Scale
  • 1.5 pounds flank steak or sirloin, thinly sliced against the grain
  • 4 cups fresh broccoli florets (about 300 g)
  • 4 cloves garlic, minced
  • 1/2 cup low-sodium soy sauce (120 ml)
  • 1/4 cup beef broth or water (60 ml)
  • 3 tablespoons brown sugar
  • 2 tablespoons oyster sauce (optional)
  • 1 tablespoon sesame oil
  • 2 teaspoons cornstarch mixed with 2 tablespoons cold water
  • 1/4 teaspoon ground black pepper
  • Optional garnishes: toasted sesame seeds, sliced green onions

Instructions

  1. Slice the flank steak thinly against the grain into strips about 1/4 inch thick.
  2. In a medium bowl, whisk together minced garlic, soy sauce, beef broth, brown sugar, oyster sauce (if using), sesame oil, and black pepper until sugar dissolves.
  3. Add sliced beef to the sauce and toss to coat. Marinate for about 10 minutes.
  4. Place the marinated beef and sauce mixture into the slow cooker. Add broccoli florets on top without stirring.
  5. Cover and cook on low for 3.5 to 4 hours until beef is tender and broccoli is cooked but still bright green.
  6. About 15 minutes before serving, stir in the cornstarch slurry. Cover and cook for another 10-15 minutes until sauce thickens.
  7. Taste and adjust seasoning if needed. Garnish with toasted sesame seeds and sliced green onions before serving.

Notes

For firmer broccoli, add it during the last hour of cooking or steam separately and add before serving. To thicken sauce, add cornstarch slurry near the end. Slice beef thinly against the grain for tenderness. Use tamari for gluten-free version. Optional oyster sauce adds richness.
