Method
- Pat the beef strips completely dry with paper towels, then season generously with salt and black pepper.
- Heat vegetable oil in a large skillet or wok over medium-high heat until shimmering.
- Add beef strips in a single layer and cook 2–3 minutes without stirring until browned. Flip and cook another 2 minutes until browned outside but slightly pink inside.
- Remove beef and set aside. Add onions to the same pan and cook for 3 minutes until softened. Add bell peppers and garlic; cook 2–3 minutes until crisp-tender.
- In a small bowl, whisk cornstarch with 1/4 cup beef broth until smooth. Add remaining broth, soy sauce, Worcestershire sauce, brown sugar, smoked paprika, and red pepper flakes. Pour into skillet.
- Return beef to the pan. Bring to a gentle boil, then reduce heat to medium-low and simmer 8–10 minutes until gravy thickens, stirring occasionally.
Notes
Substitution Tips: Use mushroom broth for umami, arrowroot powder for gluten-free, or coconut aminos for paleo-friendly. For a lighter dish, replace half the beef with mushrooms and use low-sodium broth.
