Slowly cooked beef combined with broccoli creates a flavorful dish that's tender and satisfying. Thinly sliced flank steak simmers in a blend of soy sauce, brown sugar, garlic, ginger, and sesame oil, picking up savory depth as it cooks. Broccoli is added near the end to maintain freshness and crisp texture. The sauce is thickened with a cornstarch slurry for a glossy finish. Serve hot over rice with optional garnishes of green onions and sesame seeds for a complete meal reminiscent of classic Chinese-American takeout, made more convenient at home and perfect for busy weeknights.

Tender beef slowly infused with a savory soy and ginger sauce becomes comfort food at its best here and crisp broccoli adds fresh crunch for a weeknight dinner you will crave again and again This slow cooker beef and broccoli tastes just like my favorite takeout but is even more satisfying and easy to prepare at home

The first time I made this I was amazed by how little effort was needed for such amazing flavor My kids now ask for it every time I say we are having Chinese food night

Ingredients

  • Flank steak or sirloin: Choosing the right cut means you get tender slices that soak up every bit of flavor Buy fresh beef and slice thinly against the grain for best results
  • Low sodium soy sauce: Brings the classic savory depth but keeps salt in check Look for good quality brands with clean ingredients
  • Brown sugar: Balances out the salt and adds a caramel sweetness Use fresh packed sugar for guaranteed sauce richness
  • Sesame oil: Infuses a nutty aroma and authentic Asian flavor Ideally pick toasted sesame oil for its robust taste
  • Garlic and fresh ginger: Fresh aromatics build the backbone of the sauce Choose firm garlic cloves and a plump ginger root for maximum flavor
  • Cornstarch and water: The classic thickener combo Use fresh cornstarch for a glossy smooth sauce
  • Beef broth: Adds complexity and hearty depth Opt for low sodium and choose a broth without additives
  • Broccoli florets: Fresh or frozen works Pick firm green florets for best color and crunch
  • Optional green onions and sesame seeds: Brighten the finished dish with freshness and gentle bite Pick vibrant green onions and fresh sesame seeds if using

Broccoli is easily my favorite part of this recipe since it drinks up the sauce and keeps its crunch I remember serving this for Chinese New Year and watching everyone go back for seconds because the flavors were just that good
