Ingredients You’ll Need
To make Beef & Bell Pepper Stir Fry with Sesame Seeds, you’ll need a handful of pantry staples and fresh produce. It’s simple but powerful in flavor.
For the Sauce
- 3 tbsp soy sauce (preferably low-sodium)
- 1 tbsp oyster sauce (halal-certified)
- 1 tbsp sesame oil
- 1 tbsp rice vinegar or white vinegar
- 1 tbsp brown sugar (or honey for a lighter sweetness)
- 2 cloves garlic, minced
- 1 tsp freshly grated ginger
- 1 tsp cornstarch
- 3 tbsp water
For the Stir Fry
- 400 g beef sirloin or flank steak, thinly sliced against the grain
- 1 tbsp soy sauce (for marinating the beef)
- 1 tbsp cornstarch (for coating)
- 1 tbsp vegetable oil (for marinating)
- 2 tbsp vegetable oil (for stir frying)
- 1 red bell pepper, thinly sliced
- 1 green bell pepper, thinly sliced
- 1 small onion, sliced
- 1 tbsp sesame seeds, toasted
- 2 stalks green onions, chopped for garnish
Optional for Serving
- Steamed jasmine rice or noodles
Step-by-Step Instructions
Follow these easy but essential steps to achieve a tender, flavorful stir fry that rivals any restaurant dish.
Step 1: Marinate the Beef
Thinly slice your beef against the grain — this is crucial for tenderness. Combine soy sauce, cornstarch, and oil in a bowl, then mix in the beef slices until well coated.
Let it rest for 10–15 minutes while you prepare the sauce and vegetables. This quick marinade adds flavor and keeps the meat juicy.
Chef’s Tip: If you have extra time, marinate for up to 30 minutes in the fridge for even deeper flavor.
Step 2: Prepare the Stir Fry Sauce
In a separate small bowl, whisk together soy sauce, oyster sauce, sesame oil, vinegar, brown sugar, garlic, ginger, cornstarch, and water. Stir well until everything is smooth and combined.
This sauce is the heart of the dish — slightly thick, glossy, and rich with umami.
Pro Tip: Make sure your cornstarch is fully dissolved before cooking. This prevents lumps in the final sauce.
Step 3: Stir Fry the Beef
Heat a wok or large skillet over medium-high heat (around 200°C). Add a tablespoon of oil and swirl to coat the pan evenly.
Add the marinated beef in batches (avoid crowding) and sear for 2–3 minutes per batch until the slices are browned and just cooked through. Remove and set aside on a plate.
Why Batch Cooking Matters: Overcrowding the pan causes the beef to steam instead of sear, leading to a tougher texture.
Step 4: Cook the Vegetables
In the same wok, add the remaining tablespoon of oil. Toss in the sliced onion and bell peppers. Stir fry for 2–3 minutes until the vegetables are tender but still crisp.
The goal here is to maintain the vibrant color and fresh crunch of the peppers — don’t overcook them.
Step 5: Combine Everything
Return the cooked beef to the wok. Pour the prepared stir fry sauce over everything and toss continuously for 2–3 minutes. The sauce will thicken slightly as it cooks, coating the beef and vegetables beautifully.
Chef’s Note: If the sauce thickens too much, add a tablespoon or two of water to loosen it without diluting the flavor.
Step 6: Add Sesame Seeds and Garnish
Sprinkle toasted sesame seeds and green onions over the stir fry, tossing gently to distribute them evenly. The sesame seeds bring a nutty fragrance and subtle crunch to each bite.
Step 7: Serve and Enjoy
Serve your Beef & Bell Pepper Stir Fry with Sesame Seeds immediately while it’s hot and glossy. It pairs perfectly with steamed jasmine rice, brown rice, or even noodles.
For a more balanced meal, add a side of cucumber salad or miso soup.
Tips for Perfect Stir Fry Every Time
Getting a stir fry just right is all about technique. Here are key tips to elevate your dish:
- High Heat is Key: Stir frying requires high heat to sear and caramelize the ingredients quickly without losing moisture.
- Prep Everything First: Have your vegetables sliced, sauce mixed, and beef ready before heating the wok. Stir frying moves fast!
- Slice Against the Grain: This breaks down muscle fibers, making the beef tender.
- Use a Wok if Possible: The curved sides help distribute heat evenly and make tossing easier.
- Add Sesame Oil at the End: This preserves its aroma and prevents bitterness from overheating.
- Toasted Sesame Seeds: Always toast sesame seeds in a dry pan before using — it enhances their nutty flavor.
Flavor Variations
You can customize this recipe in many ways without losing its charm. Here are a few ideas:
- Spicy Beef & Pepper Stir Fry: Add chili flakes, sriracha, or fresh red chili slices for heat.
- Teriyaki-Style Version: Swap the sauce for teriyaki glaze and sprinkle extra sesame seeds.
- Ginger Beef Version: Increase the ginger to 1 tbsp and reduce garlic for a zesty twist.
- Vegetarian Option: Replace beef with tofu or seitan and use the same sauce for a plant-based version.
- Extra Veggies: Include carrots, broccoli, baby corn, or mushrooms for more texture and color.
Serving Suggestions
This stir fry is incredibly versatile — here’s how you can serve it for different occasions:
- With Rice: Classic pairing with jasmine, basmati, or brown rice.
- With Noodles: Toss it with soba, udon, or rice noodles for a heartier meal.
- Low-Carb Option: Serve over cauliflower rice or zucchini noodles.
- As a Bowl Meal: Layer with rice, add pickled veggies, and drizzle extra sauce for a complete bowl experience.
For presentation, serve it in a black ceramic bowl or on a white plate to highlight the contrast of the colorful peppers and dark beef glaze.
Make-Ahead & Storage Tips
If you love meal prep or cooking in advance, this dish fits perfectly into your routine.
- Storage: Store leftovers in an airtight container for up to 3 days in the fridge.
- Reheating: Warm in a skillet over medium heat for best texture. Add 1–2 tbsp of water if the sauce has thickened too much.
- Freezing: Freeze cooked beef and sauce (without vegetables) for up to 2 months. Reheat and add fresh vegetables before serving.
- Meal Prep Tip: Slice your beef and prep your sauce up to a day in advance. This cuts your cooking time in half when ready to stir fry.
Common Mistakes to Avoid
- Overcrowding the Pan: Always cook the beef in small batches.
- Skipping the Marinade: Even a short marinade makes a huge difference in tenderness.
- Adding Sauce Too Early: Add it only after beef and veggies are mostly cooked.
- Overcooking Veggies: Crisp-tender vegetables give the best texture.
- Not Toasting Sesame Seeds: Raw seeds lack the toasty flavor this dish deserves.
