Tips and Variations
  • Beef Substitutions:
    • If you can’t find chuck roast or flank steak, you can also use sirloin, or stewing beef. Adjust the cooking time according to the cut you choose.
  • Soy Sauce Substitutions:
    • Low-sodium soy sauce, tamari, or coconut aminos can be used if you’re watching your sodium intake. Tamari is a good substitute for a gluten-free version.
  • Brown Sugar Substitutions:
    • Honey or maple syrup can replace brown sugar for a different kind of sweetness. Adjust the quantity to taste.
  • Sesame Oil Substitutions:
    • Toasted sesame oil provides a stronger flavor than regular sesame oil. Use it sparingly or mix it with a neutral oil like canola or vegetable oil if you find its taste too intense.
  • Spice Level:
    • If you prefer a milder dish, reduce or omit the crushed red pepper flakes. For extra heat, add a pinch of cayenne pepper.
  • Vegetable Additions:
    • Enhance the dish with vegetables like bell peppers, carrots, or broccoli. Add them in the last hour of cooking to maintain their texture.
