Ingredients

Instructions

  1. Step 1: In a medium bowl, combine 1 lb thinly sliced flank steak, 1 tbsp unsweetened dark cocoa powder, 3 tbsp soy sauce, and 2 tbsp hoisin sauce. Toss well to marinate for 15 minutes.
  2. Step 2: Heat 2 tbsp vegetable oil in a large wok or skillet over high heat until shimmering. Add 3 minced garlic cloves, 1 tbsp grated ginger, and 1 medium sliced fresh red chili. Stir-fry for 30 seconds until fragrant.
  3. Step 3: Add the marinated beef strips to the wok in a single layer. Cook undisturbed for 2 minutes to get a good sear, then stir-fry for another 2-3 minutes until beef is browned but still tender.
  4. Step 4: Add 1 sliced green bell pepper and 3 chopped scallions to the wok. Stir-fry for 2 minutes until vegetables are crisp-tender and coated in the sauce.
  5. Step 5: Sprinkle 1 tbsp toasted sesame seeds over the stir fry and toss gently before serving with steamed rice or noodles.

Total time is about 30 minutes (20 min prep + 10 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Chocolate Chili Beef Stir Fry?

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 thinly sliced flank steak from drying out.

Can I substitute ingredients in Chocolate Chili Beef Stir Fry?

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 Chocolate Chili Beef Stir Fry for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). 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.
