Pat the steak pieces dry with paper towels and season generously with salt and pepper.
Optional: Heat olive oil in a skillet over medium-high heat and sear the steak bites for 1–2 minutes per side until browned (this step adds extra flavor but can be skipped for convenience).
In a medium bowl, whisk together the beef broth, soy sauce, Worcestershire sauce, brown sugar, tomato paste, garlic, smoked paprika, onion powder, and red pepper flakes (if using). Set aside.
