Step-by-Step Recipe Instructions for Savory Beef Stir Fry with Onions and Peppers
Step 1: Prepare the Beef and Vegetables
Instructions:
Start by slicing the beef thinly against the grain. This helps ensure tenderness. You can use flank steak, ribeye, or sirloin—whichever you prefer. Once the beef is sliced, season it with salt and pepper. Next, prepare your vegetables: slice the bell peppers into thin strips, and slice the onion into thin wedges. Mince the garlic and grate the ginger.
Tip: For best results, freeze the beef for about 30 minutes before slicing. This makes it easier to cut thin slices.
Step 2: Make the Stir-Fry Sauce
Instructions:
In a small bowl, combine the soy sauce, oyster sauce, and cornstarch. Add a splash of water (about 2 tbsp) to help dissolve the cornstarch. Stir until smooth. Set the sauce aside, as you’ll use it later to create a savory glaze.
Tip: If you prefer a stronger flavor, add a bit more oyster sauce or a dash of sesame oil to the sauce mix.
Step 3: Cook the Beef
Instructions:
Place a wok or large skillet over medium-high heat. Pour in the vegetable oil and swirl it around to coat the bottom evenly. Once the oil is hot, add the beef in a single layer, cooking for 1-2 minutes on each side until it’s browned and just cooked through. Take the beef out of the skillet and set it aside.
Tip: Avoid overcrowding the pan; cook the beef in batches if necessary to get a nice sear.
Step 4: Stir-fry the Vegetables
Instructions:
In the same pan, add a bit more oil if needed. Toss in the sliced onions and bell peppers. Stir-fry the vegetables for 3-4 minutes, until they are tender yet still crisp. Add the minced garlic and grated ginger to the pan and cook for an additional 30 seconds until fragrant.
Tip: If you like your vegetables more tender, cook them a bit longer.
Step 5: Combine and Cook with Sauce
Instructions:
Add the cooked beef back into the pan with the vegetables. Pour the stir-fry sauce over the mixture and toss to evenly coat. Allow the sauce to thicken and coat the beef and vegetables, cooking for another 1-2 minutes.
Tip: If the sauce thickens too much, you can add a small splash of water to loosen it up.
Step 6: Serve and Enjoy
Instructions:
Serve the stir-fry over steamed rice or noodles, and garnish with sesame seeds or chopped green onions if desired. Enjoy your flavorful and satisfying meal!
Tip: For extra heat, add a pinch of chili flakes to the finished stir-fry.
Notes
- Ingredient Substitutions: You can swap out the beef for chicken or tofu for a different variation. The sauce pairs well with various proteins.
- Vegetable Variations: Feel free to add other vegetables like broccoli, mushrooms, or snap peas. The stir-fry is highly customizable based on what you have on hand.
- Serving Suggestions: Pair the stir-fry with a side of steamed jasmine rice, brown rice, or even quinoa for a nutritious meal.

Expert Tips for Success
- Use a Wok: A wok heats quickly and evenly, making it ideal for stir-frying. If you don’t have a wok, a large frying pan will work.
- Choose the Right Beef: For the best texture, use tender cuts like flank steak or sirloin. Avoid tougher cuts that can become chewy.
Variations and Customizations

- Vegan Option: Swap the beef for tofu or tempeh, and use a plant-based soy sauce for a vegan-friendly dish.
Storing Leftovers (Refrigeration/Freezing)
To store your Savory Beef Stir Fry with Onions and Peppers for later, follow these easy guidelines:
- Refrigeration: Let the stir fry cool to room temperature before transferring it to an airtight container. Store in the fridge for up to 3–4 days. When reheating, you can warm it in the microwave or on the stovetop until heated through.
- Freezing: If you’d like to freeze your leftovers, allow the stir fry to cool completely before placing it in a freezer-safe container or zip-top bag. It can be stored in the freezer for up to 2–3 months. To reheat, thaw overnight in the fridge or use the microwave on the defrost setting. Once thawed, heat it on the stovetop for the best texture and flavor.
Tips for Reheating: When reheating, add a splash of water or broth to prevent the stir fry from drying out. Stir occasionally to ensure even heating, and you can add a bit more sauce to bring back the flavor if needed.
Frequently Asked Questions
Can I use a different type of meat for this stir fry?
Yes! While the recipe calls for beef, you can substitute it with chicken, pork, or even shrimp. Each protein will bring its flavor to the dish, but the cooking method remains largely the same. Just make sure to adjust cooking times based on the protein you choose—chicken and pork will take a little longer to cook through, while shrimp cooks much faster.
Can I make this recipe vegetarian?
Absolutely! To make this stir fry vegetarian, you can replace the beef with tofu or tempeh. Both are excellent sources of plant-based protein and absorb the savory flavors of the sauce wonderfully. For a lighter version, you could also use a mix of hearty vegetables like mushrooms, zucchini, and eggplant in place of the meat.
Can I make this stir fry ahead of time?
Stir fry dishes are best enjoyed fresh, but you can certainly prepare the ingredients ahead of time. Slice the beef and vegetables and store them separately in the fridge. When you’re ready to cook, simply follow the steps. If you want to make the full dish ahead of time, store it in an airtight container in the refrigerator for up to 3 days, though the vegetables may soften a bit over time.
How can I make this recipe spicier?
If you prefer your stir fry with a bit of heat, you can add chili flakes or a dash of sriracha sauce to the stir fry sauce. For a more intense kick, toss in sliced fresh chilies or a spoonful of chili paste while cooking the vegetables. Adjust the spice level to suit your taste!
Can I freeze the leftovers?
Yes, you can freeze the stir fry leftovers for up to 2-3 months. To freeze, allow the dish to cool completely, then place it in an airtight container or freezer bag. When reheating, it’s best to do so in a pan over low heat to prevent the beef from becoming tough and to maintain the flavor and texture of the sauce. You can also reheat in the microwave, but be sure to cover it with a damp paper towel to retain moisture.
