How to Make Pepper Steak with Onions Recipe

Start by slicing your steak thinly against the grain. This is the number one trick for tender beef. Toss it with the soy sauce and cornstarch and let it sit while you prep everything else. Get your rice cooking now, because this comes together fast.

Heat your wok or large skillet over high heat. You want it screaming hot. Add the oil, then sear the beef in a single layer. Don’t crowd the pan. Cook it for just 1-2 minutes per side until browned but not cooked through, then remove it to a plate.

Tips for Perfect Pepper Steak with Onions

Slice Against the Grain

Look for the lines running along the steak. Cut perpendicular to them. This shortens the muscle fibers and is the single biggest factor in preventing chewy beef. It makes all the difference.

High Heat is Non-Negotiable

You’re not steaming, you’re stir-frying. A super hot pan sears the beef quickly and keeps the veggies crisp tender. If your pan isn’t hot enough, everything will stew and get soggy. This technique is similar to what gives those fluffy Japanese souffle pancakes their structure, just for a totally different result.

Ingredients

  

For the Beef & Marinade

• 1.5 lbs flank steak or sirloin thinly sliced against the grain
• 3 tbsp low-sodium soy sauce divided
• 2 tbsp cornstarch divided
• 1 tbsp vegetable oil for coating
• 1/2 tsp black pepper freshly ground

For the Stir-Fry

• 2 tbsp vegetable oil divided
• 1 large yellow onion cut into 1-inch chunks
• 1 large green bell pepper cored and cut into 1-inch chunks
• 1 large red bell pepper cored and cut into 1-inch chunks
• 3 cloves garlic minced
• 1 tsp fresh ginger grated

For the Sauce

• 1/2 cup beef broth or water
• 3 tbsp low-sodium soy sauce
• 1 tbsp oyster sauce or hoisin sauce
• 1 tbsp rice vinegar
• 1 tbsp brown sugar
• 1 tsp sesame oil

For Serving (Optional)

• 4 cups cooked white rice steamed
• 2 green onions thinly sliced
• 1 tsp sesame seeds for garnish

Method

 

1. In a medium bowl, combine the thinly sliced beef with 1 tablespoon of soy sauce, 1 tablespoon of cornstarch, 1 tablespoon of vegetable oil, and the black pepper. Toss until the beef is evenly coated. Let it marinate for at least 10 minutes while you prepare the other ingredients.
2. In a small bowl or measuring cup, whisk together all the sauce ingredients: beef broth, the remaining 3 tablespoons of soy sauce, oyster sauce, rice vinegar, brown sugar, sesame oil, and the remaining 1 tablespoon of cornstarch. Set aside. Prepare your onion and bell peppers into uniform chunks and mince the garlic and ginger.
3. Heat a large skillet, wok, or cast-iron pan over high heat until very hot. Add 1 tablespoon of vegetable oil. Add the marinated beef in a single layer, working in batches if necessary to avoid crowding. Sear without moving for 1-2 minutes, then stir-fry for another 1-2 minutes until just browned but not fully cooked through. Transfer the beef to a clean plate.
4. In the same pan over medium-high heat, add the remaining 1 tablespoon of oil. Add the onion and bell pepper chunks. Stir-fry for 4-5 minutes until they are crisp-tender and have some charred spots. Add the minced garlic and ginger and cook for 30 seconds until fragrant.
5. Return the cooked beef and any accumulated juices to the pan with the vegetables. Give the prepared sauce a quick stir (as the cornstarch may have settled) and pour it over everything. Bring to a simmer, stirring constantly. Cook for 1-2 minutes until the sauce has thickened and become glossy, coating the beef and vegetables evenly.
6. Remove the pan from the heat. Serve the pepper steak hot over a bed of steamed white rice. Garnish with sliced green onions and sesame seeds if desired.
