- 1 lb flank steak (sliced thinly against the grain): This cut becomes wonderfully tender when sliced properly and cooks quickly for a perfect protein base.
- 2 bell peppers (red, green, or a mix, sliced into strips): Choose a blend of colors to add brightness and crispness to the dish.
- 1 medium onion (sliced thinly): Adds natural sweetness and a lovely depth that complements the beef perfectly.

- 2 tablespoons soy sauce: Brings salty, savory notes essential to the authentic taste.
- 2 tablespoons oyster sauce: Adds rich, slightly sweet umami for extra depth.
- 1 tablespoon hoisin sauce: Introduces a hint of sweetness and complexity to the overall flavor.
- 1 tablespoon rice vinegar: Gives a subtle acidity that brightens the sauce and balances richness.
- 1 tablespoon cornstarch (optional, for thickening): Helps the sauce cling perfectly to the meat and veggies if you prefer it thicker.
- 1 tablespoon vegetable oil (for stir-frying): A neutral oil that allows high heat cooking without burning.
- 1 teaspoon ginger (minced): Adds a fresh, zesty note that complements garlic beautifully.
- Salt and pepper to taste: Simple seasoning layers that enhance the natural flavors.
- 1/4 cup water or beef broth (for sauce): Creates the perfect consistency and intensifies flavor when simmered.
How to Make Pepper Steak with Bell Peppers and Onion Recipe
Step 1: Prep the Beef
Start by slicing your flank steak thinly against the grain — this is key for tenderness. Season the slices lightly with salt and pepper. For an extra touch of flavor, toss the meat in a tablespoon of soy sauce and let it marinate briefly while you prepare the veggies. This simple step will make your steak juicy and packed with savory goodness.
Step 2: Cook the Beef
Heat the vegetable oil in a large skillet or wok over medium-high heat until shimmering. Quickly stir-fry the steak strips for 2 to 3 minutes until they develop a beautiful brown crust but are not overcooked. At this point, remove the beef from the skillet and set it aside—this prevents overcooking and keeps each piece tender and flavorful.
Step 3: Stir-Fry the Veggies
Using the same skillet, add a touch more oil if needed. Toss in the sliced onions and bell peppers, cooking them for about 3 to 4 minutes so they soften but stay delightfully crisp. Then add the minced garlic and ginger, cooking another minute until you can smell their fragrant magic filling your kitchen. This step ensures your veggies maintain texture and vibrant flavor.
Step 4: Make the Sauce
In a small bowl, whisk together soy sauce, oyster sauce, hoisin sauce, rice vinegar, and your choice of water or beef broth. If you prefer your sauce thicker and clingier, whisk in the cornstarch now. This balanced sauce will bring all the flavors of your Pepper Steak with Bell Peppers and Onion Recipe together beautifully, creating that signature luscious coating.
Step 5: Combine Everything
Return the cooked steak to the skillet and pour the sauce over the meat and vegetables. Stir everything together and cook for another 2 to 3 minutes until the sauce thickens slightly and every piece is coated in that rich glaze. This final step melds the pepper steak flavors perfectly, ensuring each bite is packed with savory sweetness and a touch of tang.
How to Serve Pepper Steak with Bell Peppers and Onion Recipe

Garnishes
A sprinkle of fresh chopped green onions or a handful of toasted sesame seeds can add a lovely finish to this dish. These garnishes brighten up the plate and introduce subtle texture that keeps things interesting.
Side Dishes
Pepper steak pairs wonderfully with fluffy steamed jasmine rice or simple egg noodles, which soak up the delicious sauce. For a lighter meal, serve alongside sautéed greens like bok choy or a crisp Asian-style cucumber salad for refreshing contrast.
Creative Ways to Present
For a fun presentation, try serving the pepper steak over crispy fried rice or stuffed inside warm tortillas for a fusion-style wrap. Another great option is to pile it atop a bed of cauliflower rice for a low-carb twist, letting the vibrant colors shine on the plate for a beautiful, appetizing meal.
Make Ahead and Storage
Storing Leftovers
This Pepper Steak with Bell Peppers and Onion Recipe keeps beautifully in an airtight container in the fridge for up to 3 days. The flavors actually deepen overnight, making leftovers just as tasty if not better the next day.
Freezing
If you want to meal prep or save some for later, freeze the cooked pepper steak in freezer-safe containers for up to 2 months. Defrost overnight in the fridge before reheating to preserve texture and flavor.
Reheating
Gently reheat your pepper steak in a skillet over medium heat, adding a splash of water or broth if it looks dry, to keep the meat tender and the sauce rich. Avoid microwaving when possible as it can toughen the beef, but it works in a pinch.
FAQs
Can I use a different cut of beef for this recipe?
Absolutely! While flank steak is ideal for its tenderness and quick cooking time, you can use sirloin, skirt steak, or even thinly sliced ribeye. Just be sure to slice against the grain for best results.
Is it possible to make this recipe vegetarian?
Yes, swap the beef for firm tofu, tempeh, or seitan to enjoy a vegetarian version. Use vegetable broth instead of beef broth and keep the sauce components the same for fantastic flavor.
What kind of bell peppers work best?
A mix of red, green, and yellow bell peppers makes for the best combination of sweetness and color. You can choose your favorite colors or use whatever you have on hand to keep it vibrant and tasty.
Can I prepare the sauce ahead of time?
Definitely! The sauce can be mixed and stored in the fridge for up to 3 days before cooking. This is a great time-saver and lets you focus on quick stir-frying when ready to eat.
Should I use fresh ginger or ginger powder?
Fresh ginger is recommended for its bright, zesty flavor that complements the garlic perfectly. However, if you don’t have fresh, a small pinch of ground ginger will work in a pinch, though the flavor will be slightly different.
Final Thoughts
This Pepper Steak with Bell Peppers and Onion Recipe is a comforting and delightful dish you’ll want to keep in your regular rotation. It’s quick to make, packed with vibrant flavors, and perfect for any occasion that calls for a home-cooked meal full of love.
