How to Make Stir-Fried Pepper Steak with Bell Peppers and Onions Recipe
Step 1: Prepare the Beef
Start by slicing your beef thinly against the grain—this is key for tenderness. Then, marinate it briefly in 2 tablespoons of soy sauce, 1 tablespoon of oyster sauce, and 1 tablespoon of cornstarch. This will flavor your steak beautifully and help it develop a nice sear while keeping it juicy inside.
Step 2: Mix the Stir-Fry Sauce
In a small bowl, whisk together the beef broth, 2 tablespoons soy sauce, 1 tablespoon oyster sauce, brown sugar, 1 teaspoon cornstarch, and freshly ground black pepper. Set this aside; it’s going to be the magic that ties your stir-fried pepper steak with bell peppers and onions recipe together with a silky, well-balanced glaze.
Step 3: Cook the Beef
Heat 1 tablespoon of vegetable oil in a wok or large skillet over medium-high heat until shimmering. Quickly stir-fry the marinated beef in batches for about 2 minutes each until it is nicely browned but still tender inside. Transfer the beef to a plate and keep warm.
Step 4: Sauté the Aromatics and Vegetables
Add the remaining tablespoon of oil to the pan, then toss in the minced garlic and grated ginger. Let their aroma fill the kitchen as you stir for about 30 seconds. Next, add the sliced bell peppers and onions, stir-frying for 3 to 5 minutes until they soften slightly but retain a pleasant crispness.
Step 5: Combine and Simmer
Return the beef to the pan with the vegetables, then pour the prepared stir-fry sauce over the top. Stir constantly as the sauce thickens and coats every strip of steak and vegetable in glossy flavor. This final simmer will take just a few minutes and bring the whole dish together beautifully.
How to Serve Stir-Fried Pepper Steak with Bell Peppers and Onions Recipe

Garnishes
Fresh herbs like chopped green onions or cilantro add a burst of color and brightness that perfectly complement the rich, savory beef. A sprinkle of toasted sesame seeds can also add a wonderful nutty crunch.
Side Dishes
This stir-fry pairs wonderfully with steamed jasmine rice or noodles to soak up every last bit of sauce. You might also enjoy it alongside lightly sautéed greens or a crisp Asian-style cucumber salad for a refreshing contrast.
Creative Ways to Present
For a fun twist, serve this stir-fry over warmed lettuce leaves for a hand-held, low-carb option. Alternatively, try tucking it into warm tortillas or serve it over a bed of quinoa for a wholesome variation that’s packed with nutrition and flavor.
Make Ahead and Storage
Storing Leftovers
Place any leftover stir-fried pepper steak with bell peppers and onions recipe in an airtight container and store in the refrigerator for up to 3 days. The flavors will continue to develop overnight, making it a great dish to make ahead.
Freezing
This dish doesn’t freeze as well as some others because the bell peppers and onions can become mushy when thawed. If you want to freeze it, consider freezing the cooked beef and the vegetables separately to preserve texture, and combine them fresh when reheating.
Reheating
Reheat leftovers gently over medium heat, adding a splash of beef broth or water if the sauce has thickened too much. Avoid reheating on very high heat to keep the beef tender and the vegetables from becoming overcooked.
FAQs
Can I use a different cut of beef for this recipe?
Absolutely! While sirloin and flank steak are preferred for their tenderness and quick cooking, you can also use skirt steak or even ribeye if you want a richer flavor. Just be sure to slice thinly against the grain.
Is it necessary to marinate the beef?
Marinating helps tenderize the meat and infuse it with flavor, but if you’re short on time, you can skip this step and still have a tasty stir-fry. Just add the seasoning directly during cooking and adjust to taste.
Can I make this recipe vegetarian?
Definitely! Swap the beef for firm tofu or a medley of hearty mushrooms like shiitake or portobello, and use vegetable broth instead of beef broth in the sauce for a delicious plant-based version.
What can I substitute for oyster sauce?
If you’re allergic or don’t have oyster sauce on hand, you can use hoisin sauce or mushroom stir-fry sauce as alternatives. These will maintain a savory-sweet balance in the dish.
How do I achieve the perfect crispness in the bell peppers?
To keep your bell peppers crunchy, avoid overcooking them. Stir-fry on high heat just until they are tender-crisp, usually about 3 to 5 minutes, then add the sauce and cook only briefly more until everything is hot and coated.

If you’re looking for a dish that combines simplicity with bold, unforgettable flavors, the Stir-Fried Pepper Steak with Bell Peppers and Onions Recipe is an absolute must-try.
