Let’s Get Cooking: Step-by-Step Instructions for Amazing Pepper Steak
Prepping the Beef (Key to Tenderness!)
- In a bowl, combine the thinly sliced steak with cornstarch, soy sauce, sugar, and black pepper. This marinade helps tenderize the beef and adds flavor. Don’t skip this step!
- Toss well to ensure each slice is coated. Let it marinate for at least 15 minutes, or up to 30 minutes in the refrigerator. The longer it marinates, the more flavorful it will be.
Sautéing the Veggies (Flavor Foundation)
- Heat vegetable oil in a large skillet or wok over medium-high heat. Make sure the pan is nice and hot before adding the veggies.
- Add the sliced onions and cook until softened and slightly caramelized, about 5-7 minutes. Caramelizing the onions adds a wonderful sweetness to the dish.
- Add the sliced bell peppers and minced garlic (and ginger, if using). Cook for another 3-5 minutes, until the peppers are crisp-tender. You want them to still have a bit of bite.
- Remove the vegetables from the skillet and set aside.
Cooking the Steak (Quick and Easy)
- Add a little more vegetable oil to the skillet if needed. Make sure the pan is still hot.
- Add the marinated steak in a single layer, working in batches if necessary to avoid overcrowding the pan. Overcrowding will cause the steak to steam instead of sear.
- Cook for 2-3 minutes per side, until browned and cooked to your desired level of doneness. Remember, it will continue to cook slightly in the sauce.
- Remove the steak from the skillet and set aside with the vegetables.
Making the Sauce (The Magic Touch)
- In a small bowl, whisk together the beef broth, soy sauce, oyster sauce (if using), cornstarch, brown sugar, sesame oil, and black pepper. Make sure the cornstarch is fully dissolved to avoid lumps.
- Pour the sauce into the skillet and bring to a simmer over medium heat.
- Cook, stirring constantly, until the sauce thickens, about 1-2 minutes. It should be thick enough to coat the back of a spoon.
Bringing It All Together (The Grand Finale)
- Add the cooked steak and vegetables back into the skillet with the sauce.
- Toss to coat everything evenly.
- Cook for another 1-2 minutes, allowing the flavors to meld together.
Serving Time!
- Serve the Pepper Steak With Onions immediately over cooked white rice.
- Garnish with chopped green onions and sesame seeds, if desired.
Pro Tips & Troubleshooting: Making Pepper Steak Perfection
Slicing the Steak
Slicing the steak thinly against the grain is crucial for tenderness. The grain refers to the direction the muscle fibers run. Slicing against it shortens those fibers, making the steak easier to chew.
Don’t Overcook the Steak
Overcooked steak is tough and dry. Cook the steak quickly over high heat to sear the outside and keep the inside tender. Remember, it will continue cooking in the sauce.
Sauce Too Thin?
If your sauce isn’t thickening, make sure the cornstarch was fully dissolved before adding it to the skillet. You can also whisk together a little more cornstarch with cold water (a “slurry”) and add it to the sauce while it’s simmering.
Sauce Too Thick?
If your sauce becomes too thick, simply add a little more beef broth, a tablespoon at a time, until it reaches your desired consistency.
Spice it Up!
Feel free to add a pinch of red pepper flakes to the sauce for a little extra heat. You can also add a dash of hot sauce to your individual serving.
