Quick, colorful, and loaded with flavor, this ground beef stir fry tosses tender beef with crisp veggies in a glossy, garlicky sauce—perfect for busy weeknights.
In a bowl, whisk soy sauce, oyster sauce, beef broth, rice vinegar, brown sugar, and cornstarch until smooth; set aside.
Prep vegetables: slice bell pepper, onion, and carrots; cut broccoli into bite-size florets; mince garlic and ginger.
Heat a large skillet or wok over medium-high. Add neutral oil.
Add ground beef and cook, breaking it up, until browned and no longer pink, about 4 to 5 minutes. Drain excess fat if needed.
Stir in garlic and ginger; cook until fragrant, about 30 seconds.
Add carrots and broccoli; stir-fry 2 minutes. Add onion and bell pepper; cook 2 to 3 minutes until crisp-tender.
Pour in the sauce and red pepper flakes; stir and simmer until thickened and glossy, about 1 to 2 minutes.
Turn off heat; stir in sesame oil and half the green onions. Season with salt and black pepper to taste.
Garnish with remaining green onions and sesame seeds. Serve hot over steamed rice or noodles.
Notes
For extra sauce, double the sauce ingredients. Swap broccoli for snap peas or zucchini as desired. Use 90% lean beef to reduce fat or ground turkey for a lighter option.
