Crockpot Broccoli Beef

Silky, savory beef and tender broccoli in a rich ginger-coconut aminos sauce — better than takeout and made entirely in the crockpot.
Cook Time 5 hours
Total Time 5 hours
Serving Size 5

Ingredients

  • 1 1/2 pounds flank steak thinly sliced against the grain
  • 1/2 cups coconut aminos
  • 1/3 cups beef broth
  • 3 tablespoons brown sugar packed
  • 1 tablespoons sesame oil
  • 4 garlic cloves minced
  • 1 teaspoons fresh ginger grated
  • 3 tablespoons cornstarch
  • 3 tablespoons cold water
  • 4 cups fresh broccoli florets
  • 3 green onions sliced (for serving)
  • 1 tablespoons sesame seeds for serving
  • 1/2 teaspoons red pepper flakes optional

Instructions

  • Build the sauce and add beef: Whisk together 1/2 cups coconut aminos, 1/3 cups beef broth, 3 tablespoons brown sugar, packed, 1 tablespoons sesame oil, 4 garlic cloves, minced, and 1 teaspoons fresh ginger, grated in the bottom of the crockpot. Add sliced flank steak, thinly sliced against the grain and toss to coat.
  • Slow cook the beef: Cook on LOW for 4–5 hours or HIGH for 2–3 hours, until beef is very tender.
  • Thicken sauce and add broccoli: Whisk 3 tablespoons cornstarch and 3 tablespoons cold water together until smooth. Stir into the crockpot to thicken the sauce. Add 4 cups fresh broccoli florets on top. Replace lid and cook on HIGH for 25–30 more minutes until broccoli is bright green and just tender.
  • Serve: Stir gently and serve over rice or noodles. Top with 3 green onions, sliced (for serving), 1 tablespoons sesame seeds (for serving), and 1/2 teaspoons red pepper flakes (optional) if using.

Notes

Slicing tip: Freeze the flank steak for 20–30 minutes before slicing — it's much easier to cut thin strips. 
Broccoli timing: Always add broccoli in the last 30 minutes. If it goes in at the start it will turn to mush. 
Coconut aminos: This is a soy-free, slightly sweeter alternative to soy sauce. Find it at most grocery stores near the soy sauce or in the health food aisle. 
Beef swap: Sirloin or skirt steak also work well here. 
Serve over: Steamed jasmine rice or lo mein noodles.
