Ingredients
  

  • 1.5–2 pounds flank steak or sirloin, sliced thin against the grain
  • 1 large head broccoli, cut into small florets (about 5–6 cups) or a 16-ounce bag of florets
  • 1 medium onion, thinly sliced (optional but adds depth)
  • 3 cloves garlic, minced
  • 1 tablespoon fresh ginger, grated (or 1 teaspoon ground ginger)
  • 1/3 cup low-sodium soy sauce (or tamari/coconut aminos for gluten-free)
  • 1/3 cup beef broth (low-sodium preferred)
  • 2–3 tablespoons honey or maple syrup (adjust to taste)
  • 1 tablespoon rice vinegar or apple cider vinegar
  • 1 tablespoon sesame oil
  • 1/4 teaspoon red pepper flakes (optional for heat)
  • 2 tablespoons cornstarch (or arrowroot), mixed with 3 tablespoons water
  • 2 teaspoons toasted sesame seeds, for serving (optional)
  • 2 green onions, thinly sliced, for garnish
  • Cooked brown or white rice, cauliflower rice, or noodles, for serving

Method
 

  1. Slice the beef: Freeze the steak for 20–30 minutes to firm it up. Slice thinly against the grain into bite-size strips. This helps it stay tender.
  2. Whisk the sauce: In a bowl, combine soy sauce, beef broth, honey, vinegar, sesame oil, garlic, ginger, and red pepper flakes. Taste and adjust sweetness or salt.
  3. Load the slow cooker: Add the sliced onion (if using) and beef to the slow cooker. Pour the sauce over the top. Stir to coat.
  4. Cook low and slow: Cover and cook on Low for 3.5–4.5 hours or on High for 2–2.5 hours, until the beef is tender but not falling apart.
  5. Thicken the sauce: Stir together cornstarch and water to make a slurry. Pour it into the slow cooker and stir. Cook on High for 15–20 minutes until the sauce thickens and turns glossy.
  6. Add broccoli: Stir in the broccoli florets. Cover and cook on High for 20–30 minutes, until broccoli is crisp-tender. Avoid overcooking to keep the color bright and texture snappy.
  7. Finish and serve: Sprinkle with sesame seeds and green onions. Serve over your choice of rice or noodles. Taste and add a splash of soy sauce or a drizzle more honey if you want.
