🥩 Ingredients

For the best results, use fresh ingredients and slice your beef thinly against the grain for tenderness.

For the Pepper Steak:

• 1 lb (450 g) flank steak or sirloin, thinly sliced against the grain
• 1 red bell pepper, sliced into strips
• 1 yellow bell pepper, sliced into strips
• 1 green bell pepper, sliced into strips
• 1 large onion, sliced
• 3 cloves garlic, minced
• 2 tbsp soy sauce
• 1 tbsp oyster sauce
• 1 tbsp cornstarch
• ½ tsp black pepper
• 2 tbsp vegetable or sesame oil
• ½ cup beef broth or water
• 1 tsp sugar (optional, balances flavor)
• 1 tbsp rice vinegar or Shaoxing wine (optional for depth)
• 2 stalks green onion, chopped (for garnish)

🔪 Instructions

1. Prepare the Beef:
   In a bowl, combine sliced beef with soy sauce, cornstarch, and black pepper. Let it marinate for 10–15 minutes while you prep the vegetables.
2. Heat the Pan:
   Heat 1 tablespoon of oil in a large skillet or wok over medium-high heat. Add the beef in a single layer. Sear for 1–2 minutes per side until browned but not overcooked. Remove from the pan and set aside.
3. Sauté the Vegetables:
   Add another tablespoon of oil. Toss in the sliced onions and bell peppers. Stir-fry for 3–4 minutes until tender-crisp and slightly charred on the edges.
4. Add Garlic:
   Add minced garlic and stir for 30 seconds until fragrant — be careful not to burn it.
5. Combine Everything:
   Return the beef to the pan. Pour in oyster sauce, remaining soy sauce, sugar, and beef broth. Stir until everything is well coated.
6. Simmer the Sauce:
   Let the sauce bubble for 1–2 minutes, allowing it to thicken and coat the ingredients evenly. Adjust seasoning with salt or additional soy sauce if needed.
7. Garnish and Serve:
   Sprinkle with chopped green onions and serve hot over steamed rice or noodles.

• Vegetarian Swap: Replace beef with tofu or seitan and use vegetable broth.

💡 Tips for Success

• Don’t Overcrowd the Pan: Cook in batches if necessary to achieve a proper sear.
• Rest the Meat: Allowing the beef to rest before mixing with sauce helps retain its juices.

🌍 Cultural Context and Origins

The Pepper Steak we know today originated as an American-Chinese adaptation of traditional Chinese stir-fries. It became popular in the mid-20th century as Chinese immigrants adjusted recipes to local tastes and available ingredients. Bell peppers replaced Chinese green peppers, and beef became the preferred protein due to its availability.

What makes Pepper Steak special is its balance — salty, sweet, savory, and slightly smoky — achieved with just a few simple sauces. It’s comfort food with cultural roots, bridging East and West in every bite.
