Step 1: Marinate the Shrimp : In a bowl, combine shrimp with soy sauce, sesame oil, and cornstarch. Toss to coat evenly and let marinate for 5–10 minutes while preparing the vegetables.
Step 2: Prepare the Sauce : In a small bowl, whisk together soy sauce, oyster sauce, rice vinegar, honey, sesame oil, cornstarch, and chili flakes (if using). Set aside.
Step 3: Stir-Fry the Broccoli : Heat 1 tbsp olive oil in a large skillet or wok over medium-high heat. Add broccoli florets and stir-fry for 2 minutes. Add ¼ cup water or broth, cover, and steam for 2–3 minutes until tender-crisp. Remove broccoli and set aside.
Step 4: Cook the Shrimp : In the same skillet, add a little more oil if needed. Add marinated shrimp and cook for 2 minutes per side, until pink and cooked through. Add garlic and ginger in the last minute and stir to release aroma.
Step 5: Combine Everything : Return broccoli to the skillet. Pour in the sauce and toss to coat shrimp and broccoli evenly. Stir-fry for 1–2 more minutes until the sauce thickens and glazes everything beautifully.
