Ingredients

  • 2 lb (≈ 900 g) beef flank steak or sirloin, thinly sliced against the grain
  • 2 cups beef broth
  • 1/4 cup soy sauce (or tamari for gluten-free)
  • 2 tablespoons oyster sauce
  • 2 tablespoons brown sugar
  • 1 tablespoon sesame oil
  • 3 cloves garlic, minced
  • 1 tablespoon fresh ginger, grated
  • 2 tablespoons cornstarch
  • 2 tablespoons water
  • 4 cups broccoli florets
  • Sesame seeds (optional, for garnish)
  • Cooked rice or noodles, for serving

Instructions

  1. Step 1: Build the sauce and add beef — In a bowl, whisk together beef broth, soy sauce, oyster sauce, brown sugar, sesame oil, minced garlic, and grated ginger. Place the sliced beef in the slow cooker and pour the sauce over it, ensuring the meat is mostly submerged.
  2. Step 2: Slow cook the beef — Cover and cook on low for 4–5 hours or on high for 2–3 hours, until the beef is tender and easily shredded or broken apart.
  3. Step 3: Thicken sauce & add broccoli — About 20 minutes before serving, mix cornstarch and water to form a slurry. Stir it into the slow cooker, then add broccoli florets. Re-cover and cook on high for 15–20 minutes until the broccoli is tender but still bright green and the sauce has thickened. Taste and adjust seasoning if needed. Serve over rice or noodles and garnish with sesame seeds.

Notes

  • Add broccoli only at the end to keep it crisp and vibrant.
  • For spice, add red pepper flakes or a dash of Sriracha.
  • Substitute hoisin sauce or soy sauce with a touch of honey if you don’t have oyster sauce.
  • Flank steak, sirloin, or even chuck roast all work well—just slice thinly against the grain.
  • Freeze leftovers without rice for up to 2 months for easy meal prep.
