Ingredients

Scale
  • 1 lb flank steak, thinly sliced against the grain
  • 3 cups broccoli florets, fresh
  • 1/3 cup low sodium soy sauce
  • 1/4 cup packed brown sugar
  • 3 cloves garlic, minced
  • 1 tablespoon freshly grated ginger
  • 1/2 cup low sodium beef broth
  • 2 tablespoons cornstarch mixed with 2 tablespoons water (slurry)
  • 2 tablespoons vegetable oil
  • 2 stalks green onions, sliced thin
  • 1/4 teaspoon red pepper flakes (optional)

Instructions

  1. Thinly slice flank steak against the grain into bite-sized strips. Toss with cornstarch slurry to coat evenly and set aside.
  2. Turn Instant Pot to sauté mode and heat vegetable oil. Add minced garlic and grated ginger, stirring for about 30 seconds until fragrant.
  3. Add beef strips in a single layer and sear for 2-3 minutes until browned on edges but not cooked through.
  4. Pour in soy sauce, brown sugar, and beef broth. Stir to combine, scraping browned bits off the bottom.
  5. Seal Instant Pot lid and set to high pressure for 8 minutes. Allow about 10 minutes to come to pressure.
  6. Quick release pressure, open lid, and add broccoli florets. Stir into sauce and switch back to sauté mode. Cook uncovered for 3-4 minutes until broccoli is bright green and tender-crisp.
  7. Add slurry made from 1 tablespoon cornstarch and 1 tablespoon water. Stir constantly for 2 minutes until sauce thickens to a glossy finish.
  8. Turn off Instant Pot, sprinkle sliced green onions and optional red pepper flakes. Stir and serve.

Notes

Slice beef thinly against the grain for tenderness. Sear beef in batches to avoid overcrowding. Use fresh garlic and ginger for best flavor. Add broccoli after pressure cooking to keep it crisp. Thicken sauce last with cornstarch slurry. For gluten-free, substitute soy sauce with tamari or coconut aminos.
