If you don't usually stock oyster sauce in your pantry, you might need to pick it up at the supermarket. This ingredient adds a rich, umami flavor to the dish that can't be easily substituted. Also, make sure to grab fresh bell peppers and a good quality beef sirloin for the best results.

Ingredients for Pepper Steak Recipe
Beef sirloin: Thinly sliced to ensure quick and even cooking.
Green bell pepper: Adds a fresh, slightly bitter flavor and vibrant color.
Red bell pepper: Provides a sweet contrast to the green bell pepper.
Onion: Sliced to add a mild, savory taste and texture.
Soy sauce: Brings a salty, umami depth to the dish.
Oyster sauce: Adds a rich, savory flavor that enhances the overall taste.
Cornstarch: Mixed with water to thicken the sauce and give it a glossy finish.

Technique Tip for This Recipe
When slicing the beef sirloin, make sure to cut against the grain. This will help ensure that the meat remains tender and easy to chew. Additionally, when sautéing the bell peppers and onion, avoid overcrowding the skillet. Overcrowding can cause the vegetables to steam rather than sauté, which can affect their texture and flavor.

How to Store or Freeze This Dish
Allow the pepper steak to cool completely before storing. This prevents condensation and keeps the dish from becoming soggy.
Transfer the cooled pepper steak into an airtight container. Ensure the container is sealed tightly to maintain freshness and prevent any odors from seeping in.
Store the container in the refrigerator if you plan to consume the pepper steak within 3-4 days. This keeps the beef sirloin and vegetables fresh and flavorful.
For longer storage, place the pepper steak in a freezer-safe container or heavy-duty freezer bags. Label the container with the date to keep track of its storage time.
When freezing, try to remove as much air as possible from the freezer bags to prevent freezer burn. This helps maintain the quality of the beef sirloin and bell peppers.
To reheat, thaw the pepper steak in the refrigerator overnight if frozen. This ensures even reheating and preserves the texture of the vegetables.
Reheat the pepper steak in a skillet over medium heat, stirring occasionally until heated through. This method helps retain the original flavors and texture.
Alternatively, you can reheat in the microwave. Place the pepper steak in a microwave-safe dish, cover with a microwave-safe lid or wrap, and heat on medium power in 1-minute intervals, stirring in between, until hot.
If the sauce has thickened too much during storage, add a splash of water or soy sauce while reheating to achieve the desired consistency.
Enjoy your reheated pepper steak with freshly cooked rice or noodles for a quick and delicious meal.
