Step‑by‑Step Instructions for Pepper Steak and Onions
Step 1: Prepare Sauce
In a medium bowl, whisk together ¼ cup of soy sauce, ¼ cup of oyster sauce, ½ cup of chicken stock, 1 tablespoon of cornstarch, and 2 tablespoons of water until smooth and well combined. This savory mixture will be the base of your Pepper Steak and Onions stir-fry, thickening beautifully as it cooks. Set this sauce aside for later use.
Step 2: Marinate Beef
In a large bowl, toss 1 pound of boneless sirloin tips with a pinch of salt and a splash of the soy/oyster sauce mixture. Allow the beef to marinate for about 5 minutes; this brief period helps enhance the flavors and tenderness of the meat. Meanwhile, gather your stir-fry vegetables for a quick transition to the next step.
Step 3: Sear Beef
Heat 2 tablespoons of vegetable oil in a wok or large skillet over high heat until shimmering. Add the marinated sirloin, ensuring not to overcrowd the pan; let it cook undisturbed for about 30 seconds. Then, stir-fry the beef for an additional 2 minutes or until browned and just cooked through. Remove the beef from the pan and keep it warm on a plate, allowing the residual heat to continue cooking the meat slightly.
Step 4: Cook Vegetables
In the same pan, add another tablespoon of oil if needed, and toss in the sliced bell peppers and onion. Stir-fry for 2 minutes until the vegetables are vibrant and slightly tender but still crunchy. Then, add 3 cloves of minced garlic and 1 tablespoon of grated ginger, stirring for an additional 2-3 minutes until they're aromatic and the onions become translucent.
Step 5: Combine & Thicken
Pour the prepared sauce over the cooked vegetables in the pan, stirring continuously for about 2 minutes. The sauce should thicken and coat the veggies nicely, creating a glossy finish that enhances the vibrant colors of your Pepper Steak and Onions. Add the cooked beef back into the pan, gently mixing everything together until heated through.
Step 6: Finish & Serve
Once everything is well combined and hot, remove the pan from heat. Top your Pepper Steak and Onions with chopped green onions for a fresh crunch, and drizzle with optional hot sauce for added kick. Serve this delectable stir-fry over warm rice or noodles for a complete, satisfying meal that’s sure to beckon family to the table.

Expert Tips for Pepper Steak and Onions
- Don’t Overcrowd: Avoid adding too much beef to the pan at once; this can lead to steaming instead of searing, preventing that lovely caramelization on your sirloin tips.
- Timing is Key: Keep an eye on the bell peppers and onions while cooking; stir-fry them long enough to retain their crunch but not so long that they become mushy.
- Sauce Consistency: Adjust the amount of cornstarch based on your sauce thickness preference; a little can go a long way in achieving that glossy finish you desire for your Pepper Steak and Onions.
- Flavor Boost: If you have more time, consider marinating the beef longer than 5 minutes to deepen the flavor; even 30 minutes can make a difference!
- Taste as You Go: Always taste your sauce and adjust seasonings before adding the beef back for the final mix; this ensures your dish is perfectly seasoned to your liking.
- Versatile Add-ins: Feel free to incorporate other vegetables such as broccoli or snap peas; they add more color and nutrition to your dish without complicating the recipe.

Pepper Steak and Onions Recipe FAQs
How do I choose the best bell peppers for this recipe?
Absolutely! Look for bell peppers that are firm, shiny, and vibrant in color. Avoid those with dark spots or wrinkles, as they can indicate overripeness. Opt for a mix of colors to add visual appeal to your dish!
What is the best way to store leftover Pepper Steak and Onions?
Store your leftovers in an airtight container in the fridge for up to 3 days. If you plan to keep it longer, it’s a good idea to freeze it. Make sure it cools completely, then transfer to a freezer-safe container or bag—this will keep it fresh for up to 2 months!

What should I do if my sauce is too thin?
No problem at all! If your sauce isn’t thickening, mix 1 teaspoon of cornstarch with 2 teaspoons of water to create a slurry. Gradually add this mixture into the sauce while stirring continuously over medium heat until it thickens to your liking.
Are there any dietary considerations I should be aware of?
Very! If you or someone you're serving has allergies, make sure to check the ingredient labels for allergens like soy or oyster sauce.
