Ingredients

Scale
  • 1.5 pounds flank steak (or sirloin, or chuck roast), sliced against the grain into 1/4-inch strips
  • 3 cups fresh broccoli florets (about 2 medium heads)
  • 1 medium yellow onion, thinly sliced
  • 4 cloves garlic, minced
  • 1 tablespoon fresh ginger, grated
  • 1/2 cup low-sodium soy sauce
  • 1/4 cup brown sugar, packed
  • 1/4 cup low-sodium beef broth
  • 2 tablespoons oyster sauce
  • 2 tablespoons cornstarch
  • 2 tablespoons water
  • 1 tablespoon sesame oil
  • 1/2 teaspoon red pepper flakes (optional)
  • Salt and pepper to taste
  • Cooked white rice (jasmine or basmati) for serving
  • Sesame seeds for garnish
  • Green onions, sliced, for garnish

Instructions

  1. Place flank steak in the freezer for about 15 minutes to firm up. Slice into thin strips (about 1/4-inch thick) against the grain. Season lightly with salt and pepper.
  2. In a medium bowl, whisk together soy sauce, brown sugar, beef broth, oyster sauce, minced garlic, grated ginger, sesame oil, and red pepper flakes (if using) until brown sugar is mostly dissolved.
  3. Place sliced onion at the bottom of a 6-quart slow cooker. Add sliced beef on top, then pour garlic sauce over everything. Gently toss to coat beef, keeping onions at the bottom.
  4. Cover and cook on low for 4-6 hours or on high for 2-3 hours, until beef is fork-tender.
  5. About 30 minutes before serving, steam broccoli florets until bright green and just tender (3-4 minutes in a steamer basket or 2 minutes in the microwave with a splash of water). Drain well.
  6. In a small bowl, whisk together cornstarch and water to make a slurry. Remove lid from slow cooker and stir in slurry. Cook uncovered for 10-15 minutes, stirring occasionally, until sauce thickens to a glossy consistency.
  7. Gently fold steamed broccoli into the slow cooker. Let warm through for about 5 minutes. Serve over steamed rice, garnished with sesame seeds and sliced green onions.

Notes

For best results, slice beef against the grain and add broccoli at the end to keep it crisp-tender. Don’t skip the cornstarch slurry—it gives the sauce a glossy, restaurant-quality consistency. Leftovers keep in the refrigerator for up to 4 days and can be frozen for up to 3 months.
