Instructions

  1. Step 1: In a bowl, toss 12 oz thinly sliced flank steak with 3 tbsp soy sauce and 1 tbsp cornstarch until steak is evenly coated; set aside for 10 minutes.
  2. Step 2: Heat 2 tbsp vegetable oil in a wok or large skillet over high heat until shimmering, about 1 minute. Add marinated beef and stir-fry for 2-3 minutes until browned but still tender; remove beef and set aside.
  3. Step 3: In the same pan, add 1 sliced red bell pepper, 1 sliced yellow bell pepper, 1 tbsp finely grated ginger, 3 minced garlic cloves, and 1/2 tsp red chili flakes; stir-fry for 3-4 minutes until peppers are crisp-tender and fragrant.
  4. Step 4: Return beef to the pan along with 2 sliced green onions and drizzle 1 tsp sesame oil; toss everything together for 1 minute until well combined and heated through. Serve immediately.

Frequently asked questions

How do I store leftover Spicy Beef Stir-Fry with Bell Peppers and Ginger?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep flank steak from drying out.

Can I substitute ingredients in Spicy Beef Stir-Fry with Bell Peppers and Ginger?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Spicy Beef Stir-Fry with Bell Peppers and Ginger for a different number of people?

The recipe is written for 3 servings. Multiply each ingredient by (your serving target / 3). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
