Spicy Beef & Bell Pepper Stir-Fry with Brown Rice

Lean beef and rainbow bell peppers are flash-stir-fried in a punchy, low-sugar sauce and served over fiber-rich brown rice for a light-but-satisfying lunch that supports steady afternoon energy.

Ingredients

• 1 cup dry brown rice (or 3 cups cooked brown rice)
• 1 lb (450g) lean beef steak (sirloin, rump, or flank), thinly sliced against the grain
• 3 bell peppers (any colors), sliced into 1 cm / ½-inch strips
• 1 medium onion, thinly sliced
• 3 cloves garlic, finely minced
• 1 tbsp fresh ginger, finely grated (or 1 tsp ground ginger)
• 2 tbsp low-sodium soy sauce
• 1 tbsp rice vinegar (or lime juice)
• 1 tbsp sesame oil (optional but recommended for aroma)
• 1 tbsp cornstarch
• 1/3 cup water
• 1–2 tbsp chili garlic sauce (or 1–2 tsp chili flakes + 1 tsp sriracha, to taste)
• 1 tsp honey (optional, for balance; omit for lower sugar)
• 2 tbsp neutral oil (avocado, canola, grapeseed), divided
• 1/2 tsp black pepper
• Salt, to taste (go light if using soy sauce)

Method

• 1

  Step 1: Cook the brown rice

  Rinse 1 cup brown rice until the water runs mostly clear. Cook according to packet directions (typically 1 cup rice + 2 cups water, simmer covered 25–30 minutes). Rest off heat 5 minutes, then fluff.

  Step 2: Slice the beef properly

  Pat beef dry, then slice *thinly* against the grain (this is key for tenderness). If the beef is hard to slice, chill it in the freezer for 10 minutes to firm up.

  Step 3: Make the spicy stir-fry sauce

  In a small bowl, whisk together soy sauce, rice vinegar, sesame oil (if using), chili garlic sauce, honey (if using), cornstarch, water, and black pepper until smooth.

  Step 4: Sear the beef (fast and hot)

  Heat a large wok or skillet on high until very hot. Add 1 tbsp oil, then spread beef out in a single layer. Sear 60–90 seconds until browned on the underside, then toss for another 30–60 seconds until mostly cooked. Transfer to a plate.

  Step 5: Stir-fry the vegetables

  Return pan to high heat. Add remaining 1 tbsp oil, then onion and bell peppers. Stir-fry 3–4 minutes until crisp-tender with a few browned edges. Add garlic and ginger and stir-fry 30 seconds until fragrant.

  Step 6: Bring it all together

  Return beef (and any juices) to the pan. Give the sauce a quick re-whisk, then pour it in. Toss continuously for 60–90 seconds until the sauce turns glossy and lightly coats everything. Taste and adjust: more chili for heat, a splash of water if too thick, or a tiny pinch of salt if needed.

  Step 7: Serve

  Divide brown rice among bowls and top with the spicy beef and peppers. Eat immediately for the best texture.

Tips

• **Make it extra healthy (still tasty):** Use sirloin or flank, trim visible fat, and keep peppers crisp-tender to preserve nutrients; brown rice adds fiber for steadier energy.
• **Lower sodium:** Use low-sodium soy sauce and lean on vinegar/lime and chili for punch.
• **More vegetables (pantry-friendly):** If you have them, add sliced mushrooms, snap peas, broccoli, or baby spinach—stir-fry firm veg with peppers; wilt spinach at the end.
• **Gluten-free:** Swap soy sauce for tamari or coconut aminos (both are great here).
• **Meal prep / storage:** Keeps 3–4 days in airtight containers. Reheat gently with a splash of water to loosen the sauce (microwave 1–2 minutes, stirring halfway).
• **Lunch-friendly serving idea:** Pack rice and stir-fry separately; combine just before eating to keep peppers crisp.
